A supercharger is a device that forces more air into the engine. Since it’s driven by the engine, it can help the engine make more power, especially at lower speeds.
Power adders are upgrades that help an engine make more power. They usually work by getting more air into the engine so it can burn more fuel efficiently.
A turbocharger uses the engine’s exhaust to spin a device that pushes more air into the engine. More air can mean more power, as long as the engine is set up to handle it.
An air intake is how air gets into the engine. If the intake is restrictive, the engine can’t breathe as well—so upgrading it can help the engine perform better.
The air filter keeps dirt out of the engine. If it gets clogged, it can make it harder for the engine to get the air it needs to run well.
Term
restricting my performance
This is about anything that makes it harder for the engine to breathe. If air can’t flow freely, the engine can feel weaker and use fuel less efficiently.
Velocity here means how fast the air is moving into the engine. If the intake is restrictive, the air doesn’t move as well, and the engine can lose power.
Concept
boost of ice
They’re talking about ways people try to push extra air into an engine to make it feel stronger. If the engine can use that extra airflow, it can make more power.
Cams (camshafts) control valve timing—when the engine opens and closes its intake and exhaust valves. Changing cam profiles can shift where an engine makes power and torque, which matters for both acceleration feel and fuel economy.
The Dodge Charger is a large performance car made for fast acceleration. People often modify them to make more power, especially if they’re interested in racing or quick launches. It’s brought up when someone is talking about experimenting with upgrades and results.
A “bagger” is a touring motorcycle with bags (saddlebags) and usually a big fairing. The hosts are pointing out that this one is being used for racing, not just cruising.
A brushless fan is a fan driven by a motor that doesn’t use brushes. It can spin efficiently and reliably, which helps when you’re trying to move a lot of air.
A dyno is a test machine that measures how strong an engine is. Instead of guessing, you can try different parts and see what actually improves power or efficiency.
A backing plate is a support piece that helps hold the intake part in the right position. Where it sits and how it’s shaped can change how smoothly air flows into the engine.
Wide open throttle means you’re pushing the gas pedal all the way down. That’s when the engine gets the most air, and dyno tests often measure power at that extreme.
Atmospheric pressure is how heavy the air is where you live. If the air is heavier, engines can usually get more oxygen, which can change how much power you make and how the engine runs.
Concept
altitude vs air density (Denver vs Florida)
Places at higher altitude have thinner air. Thinner air means less oxygen for the engine, so the same setup can feel different depending on where you ride or drive.
The throttle blade is a small valve that controls how much air can get into the engine. When you open it, the engine gets more air quickly, so it reacts faster when you press the gas.
Throttle response is how quickly the car or bike reacts when you press the gas. Better throttle response means it feels like it “gets going” right away instead of after a delay.
Turbo lag is the hesitation you can feel when you hit the gas and the turbo hasn’t started boosting yet. It’s basically a short delay before the engine gets the extra airflow.
Vacuum here means low pressure in the intake. The idea is that some systems need time to “pull” air in, while the setup being discussed already has air ready so it doesn’t feel delayed.
“psi” is a unit for pressure. The speaker is saying that at baseline you’re relying on normal air pressure (around 14 psi) to push air through the intake.
Volume efficiency is a measure of how well the engine fills its cylinders with air. If it’s high, the engine can make the airflow it needs more efficiently.
Term
750 cfm carburetor
A carburetor’s CFM rating is basically how much air it can handle. The speaker’s point is that if the carb is way bigger than what the engine can use, it won’t perform as well.
20–60% throttle describes the common part-throttle operating range where engines spend a lot of time in real-world driving. In that range, throttle opening and airflow matching (not just peak WOT capability) strongly influence response and efficiency.
Higher altitude means thinner air. Since engines need oxygen to make power, thin air can make the engine feel weaker or less responsive unless it’s tuned for it.
The idea is that if the engine gets air more easily, it doesn’t need as much gas to maintain speed. Less throttle at cruise can mean better fuel economy.
Throttle position tells you how much you’re pressing the gas pedal. If you can go the same speed with less throttle, the engine is working more efficiently.
The air cleaner is the part that filters the air going into the engine. If you change it, the engine can breathe differently, which can change how the bike runs.
This is an airbox with a fan that helps push air into the engine. The idea is to make sure the bike gets enough air during racing so it can run faster.
Butterfly valves are like adjustable doors for the air going into the engine. If they open quickly, the engine gets the air it needs faster when you press the throttle, so the bike feels more responsive.
Hood scoops are openings on the body that help funnel air toward the engine intake. The idea is to get more useful airflow to help the engine run better.
Fuel injection is a modern way of adding fuel to the engine using electronically controlled nozzles. It can make the bike run more smoothly and respond better than older carburetor setups.
“Carbureted” means the bike uses a carburetor to mix fuel and air. Fuel injection does that job more precisely, which usually helps with efficiency and smooth running.
“Timing” is when the engine’s spark happens during the engine cycle. Changing it can help the fuel burn at the right moment for more power and better efficiency.
They’re talking about how better fuel/air mixing can make dirt bikes feel stronger and use fuel more efficiently. They mention motocross, trails, and enduro as places where those improvements show up.
Term
cordless
“Cordless” means it runs on a battery instead of a plug. They’re using it as an example of how batteries and efficient motors can deliver a lot of power.
Brushless motors are electric motors that don’t use physical brushes to run. They’re generally more efficient and can pack more power into a smaller package.
Brand
Harley one
They’re talking about two different filter designs, including one associated with Harley. The main idea is how the filter is built and how it fits without looking bulky.
The Rolls-Royce Phantom is a very expensive luxury car designed to feel smooth and quiet. It’s known for being a top-of-the-line sedan rather than a racing car. It may be mentioned in a story because it’s noticeable and signals luxury right away.
A utility patent is the kind of patent that covers how a product works, not just how it looks. The speaker is saying their invention is about function—what it does to the engine system.
An internal combustion engine is the type that burns fuel inside the engine to make power. The speaker is saying their idea applies to gas/diesel-style engines.
LIVE
It is two guys garage podcast. He is Kevin Byrd. I am Willie B and man today
I love this we're going back to two wheels y'all most often times we talk four wheels
But today we're talking to two-wheel love because this is a really cool invention with a really cool cat
I stumbled upon Kevin like four wheels whether you're doing it honestly on 234 wheels six wheels
I don't care what you do it on
As long as you're getting a little throttle therapy, I think that makes everybody happy
And in a day we got some real throttle therapy man. That's right. That's right now
This is a new one for me
So I'm kind of coming into this like super fresh
So looking forward to kind of getting some of the skinny and it's all about right the intake side
Building power Kevin's smartest car guy I've ever met my life. So he's gonna get this really easy
It's simple right more air right you get a more fuel more spark more power
So on a on a motorcycle and on any car, right?
We know how difficult power adders can be power adders like turbos and superchargers
You know, they they have their place
There's no arguing that when you want to make crazy nutty power
But let's just talk two wheels and power adders
You don't see a lot of turbos and superchargers you're starting to on some but man that costs huge money
But nowadays you can get a little more power than the other guy simply by adding a really cool air intake
Think about your air filter. So you've seen air filters on your dirt bike, right?
How many times have you changed the air filter yet on your dirt bike? Oh, yeah, well, you know cleaned it oiled it all that
Yeah, yeah, right. So imagine if there was a way that that air filter could actually
Shoot air into your your fuel injection into your system, right? If you could speed that velocity up
What as opposed to clogging the air as opposed to restricting my performance, right?
Yeah, imagine if if you will a fan
inside of that air filter
You're like, wait a minute. What what do you mean a fan?
So we've seen this before it was the I want to say it was the the 24 hour of lemons
We saw some guys take hairdryers, you know and shoving their air intake and actually make some power
Yeah, we've seen you know over the years, right people putting leaf blowers or anything else
You know their hot rod or whatever and and you know try to go out there and make a home brood sort of boost of ice
Yeah, yeah, but this is something not only increases power, but miles per gallon
Unbelievable and and there's honest God
There's crazy science and equations and math around it and the guy we're gonna get into today Kevin
Our other Kevin for now one Kevin birds gonna go his bird
But our guest Kevin today has really got it down. He's he's been pursuing something
That was an idea to concept that it makes sense when you think about it. However
Application there's some big hurdles and when you think about what what he's done
And you know if you're moving the needle say you have 10 horsepower
If you increase 10 horsepower by a horsepower or two, man
You made a big impact, right on on how that feels how that 10 horsepower feels
But if you're you know if you got 40 horsepower and you're making a difference on
Mouth per gallon and how it feels and torque man
You could definitely feel that and that's what that's what it's all about is getting power that you could feel at a price
You can afford and I just made that up. That's something that somebody should take that's a tagline like Kevin
If you want to use that feel free
But that was just on the fly. I mean that was almost whoo. That's worth the price of admission right there
But Kevin man, welcome welcome to the podcast. So where where did you get inspired to go down this road?
I raised my bagger. I've been racing my bagger for since 2008 for top speed and
Over the years I've been trying different things different motor combos different cams different exhausts different trying different things
I ran a pro charger on my bike for a couple years to see on that but
Phenomal for power great. They were on extremely hot and everything but they were unreliable for power and
I've always been trying to promote that my performance packages need to be able to be ridden from state to state and
Doesn't leave the customers stranded somewhere along the line in the middle of nowhere and man
You came up with something as simple if you understand
What what it is every engine out there is nothing more than an air pump, right? It's a big fancy air pump
Yeah, huge. It's a huge air compressor. How fast can you get the area and how fast can you get it out?
That's the main thing
It's like a bank account you put it in you take it out you lose interest
All right, so look man. We got a great way if you own a motorcycle to increase power again
And it won't break the the book as far as savings book the checkbook the pocketbook
And it's really clever what he did and their hurdles he faced we'll get into it next
But during the break check out straight shooter air intake. You'll get a glimpse into what we're gonna be talking about
It's two guys garage podcast. He's Kevin bird. I will it be we're talking to you after the break
It is two guys garage podcast he's Kevin bird I will it be
He's gonna be referred to as bird from this moment forward because our guest Kevin
Kevin joins us now. Do you want to check out something called straight shooter air intake?
He has a motorcycle shop in Colorado called Rhodes skulls and apparently when he said he was racing a bagger
He's not playing y'all the guy has been a glamist on his bagger setting world speed records
That's saying something when you think about a bagger
Most people see bagger on a highway with a dude all leathered up with his wife on the back running groceries or toys
To the latest you know toy driver, you know Santa Claus run
But when you're thinking baggers this dude's been on the Bonneville soft flats cracking 150 plus ass
So that's hauling the mail for a bagger
Kevin welcome welcome to podcast and it man. I gotta ask you bro
We me and bird here. We we adore speed in every shape form of fashion
It's that quest for speed that drove you to this straight shooter air intake
But let's walk through the early steps man. How'd you come up with the idea?
What made you go this route and and tell me a little bit about that pursuit for speed?
Well, uh, beans. Yeah, I had that pro charger on my bike and I mean, let's be honest
It's a turbo pro charger. You're getting power and what are they doing? They're jamming air and so I came back from a Georgia race
One year and I was just trying to think about how do I get more air into my bike?
And so I started getting down and looking in and searching the internet and
Behold I found a fan and I just started drilling holes into a $500 air cleaner to figure out how to get that fan to work to blow
Arian now bird you'll appreciate this Kevin once told me he said man. This is how I came up with it
I ain't Mary. I don't have any kids
I lived in a dino shop for years and basically that was his life man. It really was. Oh, yeah
I mean, I I still to this day
If you find me here most of the times on the nights and weekends, I'm in the dino
Finding out what combinations work, you know, and what doesn't work, you know
And don't get bamboozled on what's out there for sale and everything and stuff and for instance this product
With this air cleaner, I would be the first one to throw rocks at it, you know
There's a there's a working but until I put it through the test and found out. Oh boy
We just left there's been a lot of force power left on the table that no one's paying attention to well
Give us a give us a little bit of walkthrough because right someone thinks a fan like it's just you know
Those big old plastic square box fans just kind of duct tape to the side of your bike
Like how did you integrate it in? What's the size and shape?
Do you see this fan hanging off the side of your bike as it integrated in somehow like yeah
Where what are you talking about a fan explain? What kind of fan?
It's it's it's a it's a brushless fan. It's a runs at 7500 rpms blows 150 cfms in and it's blown into wind speed at
A 25 to 27 mile an hour wind speed right directly into your intake
Oh from where though from where?
It's underneath the air filter element. Uh, for instance, this is the harley davis
The harley davis an air cleaner here. Um, you know as far as that goes, right?
You can't see it in anything, but it's inside there the fans inside underneath the air filter element
and so for instance, uh
You can tell that on this one here. It's it had to keep it at the aesthetically pleasing to the eye
But you can see here and hear it
And you can oh wow
So you for let me okay, let me explain what's going on for people who can't oh, that's wow
They can't maybe see so the the regular conical shape air filter you see on the side of a harley
Right, whether it's a k and n or something else what he's done is put this little device inside that conical shape filter
right that
Moose moose air
From the outside that filter through the filter and straight into the intake and that fan that you just heard
He was just holding it up to his
Extraordinarily long goatee, which i'm sure is a riot when he's driving his harley down the road
Um, it was blowing into wind like he's doing 45 miles an hour. So it's something that obviously
You see the effect right there now if it's going to help your bike if it's going to give you power
It's going to give you performance it gives you miles per gallon
He had no idea if it was going to do that or not, but he had an idea
So you take this idea and what happens? How do you start assembling this what has become the straight shooter air intake?
Uh, but by all means test one on the dyno trying to figure out what's working what doesn't work
How you know how to set it up the design of the backing plate? Um has a lot to do with it. Um
I tried different things at the products that are out there on
On people's air cleaners that they have designed. I've tried some of their stuff kind of seeing what works. What doesn't work
Um, and then I finally got working with this company to build these special fans for me
To be able to run at such a high rpm and put out that amount of air for the sides of the fan
Um, do not make me wrong. We get all the time. It's a computer fan
It's not a computer fan if you've got it a fan in the computer like this you're mining bitcoin
You're not
You're not it's not your local home computer
Um, but they that's a hard thing to get over and then too is like you guys already know
You're not a motive industry back in the 90s
They had a thing called the I think it was a turbulent or something like that
That they put inside the tube and it had a fan and everything and I had to fight that for my patent
Um and everything that why you know why that didn't work and this does
Um, but it comes down to it is is just trial and error figuring out what worked
And then all of a sudden when I got it to a certain point, that's when I really started noticing it and
coming over it with everybody
They're so used to
dino numbers
It's been instilled to us and everybody in the automotive truck anything any
Horsepower and torque numbers. What's it give horsepower and torque? What's it do? You know, they don't know what they don't understand is that's wide open throttle
Yes, they're chasing that holy grail of who's got the most horsepower and torque
But they don't realize is when they ride on the road you're only at 25 30 throttle at any given time
And so you're I'm keeping constant air pressure against the throttle blade
So when you wick the throttle you get fast quick acceleration quick throttle response cooler intake air temps
Increase the horsepower and torque and the number one thing that everybody's come feedback is increase of fuel mileage
So do you run it constantly then that that higher speed or is it somehow controlled with rpm or
Twisting the throttle or anything like that? I actually had an electrical and mechanical engineer worked for the automotive industry to come in to make me a controller
Um, and I took him through all the steps of how I developed this and everything and he looked like lurch off the adams family
He was a tall seven foot tall dude
He had a scowler look on his face and then I used to taking him around showing him everything
And by all means in the back of my head, I was like, oh boy, this guy doesn't like it
He's gonna tell me to stop don't waste my money on my patent in there
Hang and when I got done I asked him I says, what do you think?
And he smiled from ear to ear and he said congratulations
He goes, I don't think anybody will know the amount of time and technology and setup you did designed up into this
He told me I hit something. I didn't even know I was hitting and I
That's when I was like, okay, what'd I hit? I know what the dyno tells me. I know what the bike tells me
I know what it feels I can see it
you know
Constant air pressure against that throttle blade
He says I can slow the fan blade down. I can even speed it up faster than you the fan
Will you you know if you wake the throttle?
He says but you keep a constant air pressure against that throttle blade
So when you wake that throttle your bike don't have to work so hard to get that air in there
um kind of
so now
Kevin let me let's point out something that has has gone kind of under the table
He's in Denver, Colorado where the just atmospheric pressure
Is significantly different than it is say in florida
Or you know where you're at or anybody at sea level here. It's 14 seven or something along those lines
You know
Down at down at different altitudes air is going to act and feel much different as it gets consumed
In any sort of engine especially, you know at this altitude where air is one of the things you're starved for
So you can see how this component keeping constant pressure on that throttle blade and he's right when you're driving around
You know, I wicked up all the time at 100 percent. It is 25 to 45 to 50 percent
You know on how you ride your motorcycle
So having that constant pressure on that throttle blade you can see how that response time would be a lot quicker
Uh in that throttle response
Much happier when you have that air right there. Well, it's like the opposite of turbo lag, right?
You're not waiting for anything. It's already there as soon as you right crack the throttle correct
Correct. Just like you said, right? You're not trying to pull and and right create a vacuum
And then you only have that 14 psi of atmosphere trying to push its way through the filter and down the inlet
You're already sitting there with it. Uh ready to rock. Yeah, and and and that's the thing too is a lot of people don't understand too is
um
They're all they're all instilled with the dyno numbers
But now they're instilled with your your motors being so big they they say it's going to be robbing me of the air flow or the
Power and everything I need to get in there
But they really don't realize is is just for instance a 129 cubic inch motor
at uh volume efficiency of 85 percent only needs 96 cfms
But they don't understand that. Yeah, I was going to ask you what that yeah that baseline is because I've seen
Like I said some kind of homebrew version
You know, whether it's in a hot rod magazine article or something where you know
some are on the internet somebody's put a leak blow on their car and uh, you know, usually what it seems like
I've noticed is on a big v8. They run out of steam
Right, this fan just doesn't have enough oomph to keep up with a 750 cfm carburetor
But when you only have a two-cylinder right a v twin or a tv or whatever that's making a whole lot less
You know size wise making a whole lot less power
That fan actually has
What sounds like the oomph to keep up from right idle to to wide open correct?
And that's why I even raced my bike down at bonneville this last august with a 129 cubic inch motor with stock heads stock intake stock valves
Did the cam change? I had the brocks performance carbon fiber wheels on there with this brocks performance swing arm
And I rode it from northern colorado to bonneville
Raced it and rode home got 41 miles to a gallon running 85 90 miles an hour
And top speed was 150
So just to show everybody if it's going to rob me of power
It shouldn't let me go 150 miles an hour for it's wide open for three miles. Yeah, man packers don't do that
Yeah
I think what you've done that I haven't seen other people do is
right size
Right, you've you've right sized the fan capability to the size of the engine and the air demand
Correct, correct. You know everybody over overlooks it. They don't look I mean anybody can go on the internet and try to just google up
CFMs for an engine and come to summit racing and you put in your rpm and your size of your motor
It's going to tell you what you can do is at you know a street legal side a straight car of 85 percent or
up racing side of 110 percent
What is it going to need for CFMs and no one ever talks about that the throttle blade is your restriction
Um, not you're not riding at wide open throttle like dinos and the head work. Everything's done wide open throttle
Most of us are driving around with that thing, you know, like you mentioned that that you know 20 to 60 percent
We live kind of there
Um, and you know response especially the altitude especially here and especially like you mentioned on a smaller engine
Right, you could feel this number that's up taking performance because like you said the air is there
It's feeding it and it's um, it's pliable you feel that in the response something you don't normally
You know, you wouldn't feel in a v8, you know, so way cool
Uh, we're going to take a break now, but when we come back we're talking some of the hurdles
You had some of the testing you've gone through and applications because if you think it ends with baggers
You'd be sadly mistaken
Kevin and I both love dirt bikes
And this man has found a way to increase horsepower
And yeah in our old dirt bikes and new dirt bikes
Man, this is this is unbelievable you guys
This is a great trick and this is the two guys garage podcast. He's kevin bird. I'm willy b. We're back happy to break
It is two guys garage podcast. He is kevin bird. I am willy b and
Man, we have our boy kevin on check out this site. It's called road skulls. That's the name of his shop
He's created something called the straight shooter air intake and we just kind of went through the process of you know
Matching that fan to the right size engine intake
What what's really cool is the amount of rnd research amount of time on a dyno
And the amount of real-time racing he's done the biggest
Wow factor in this has been the gas mileage. Do you know why that is?
Kevin why why would gas mileage be so drastically increased?
um with this
Well, this is distant of this fan
Well, be honest with you
You know by watching and looking and seeing on everything on the dyno and stuff is
Say you're running at 85 miles an hour down the highway
Your throttle position might be at 30 35 throttle
Well, now you got the air getting in there at 25 throttle and it's still getting out of that much
Power to be able to maintain 25 throttle at 85 instead of 35 throttle
It's one of the ones that I feel it is one of the biggest reasons on the fuel mileage and everything and uh
Yeah, I just got back from arizona bike week sold a whole bunch down there
And the biggest thing everybody came back to his fuel mileage
One guy said he gained 30 miles to a tank by just installing that air that week
That's a big improvement man and traveling on bike week
What about restrictions because a lot of people would argue if they first see that
Probably the argument they would have against it is that big speeds or higher, you know rpm
It would be a restriction, but you've tested this right you've you've put that up against it and what'd you find?
Yeah, well, I've done this uh before I even started going to the market with this and everything I said
My I had to have enough testing to make sure that none of the stuff on the
No one's bike was going to get blown up by my product because I should I shouldn't have come into forward to buy anybody any motors
So I've tested it in quarter mile half mile mile bonneville's three miles
Um, I've had it on customers bikes since 2017 2018 testing them running them giving me their feedback, you know of uh
The how it fits on their bike compared to what it needs and everything
And don't get me wrong when we first started out with the fan and everything the first fan we started with
It wasn't putting enough air flow to it. And uh, you know, it was it was kind of bulky fan and anything
Um until we started getting into the technology having the brushless fans
That's when it was became a game changer because the brushless fans a brushless technology is amazing man
I got I got a remote control brushless car that runs 74 miles an hour
It's crazy
Um, all right, that's some crazy technology
But you knew you hit something and people giving you this feedback had to feel pretty positive
I feel like you're just hitting your stride in this you put up big numbers at bonneville. Anybody's ever been out there
It's a true testing ground
Uh, man, and you started moving over to different applications because you ride a Harley bagger
I ride a you know a v max yama v max
Do you have anything for guys that rides something other than a bagger?
Because I know last week talks you had an amazing amount of great stats and facts for dirt bikes
And this is gonna be
Kevin wait till you Kevin bird wait till you hear this. Yeah, so what I did is I
I started stumbling on and I was like, you know, we all grew up on hard dirt bikes, you know and stuff
So I started looking into them and they don't need as much air even a 450 at
13 000 rpms only needs like 105 cfms
So I started designing them for them and everything and like this one here is my yamaha air
air cleaner and all it is is, you know, and you get the same thing but
Wow
Like a jet engine taking off man
And it fits in there in the normal application all they got to do is change your air filter cage out with this
Plugging the wire hook to the battery and it comes with the um a push on switch
So now I've got him designed for the dirt bikes. I got him designed for the ktm husk of arna gas gas
Honda and uh, then uh, yamaha
all fuel injection and then I've designed the the new um,
One is I got designed for and I got a kid out there. He's a three-time champion on the west coast arena cross
And I came up with the air cleaner box
Like this that now has the fan built into this box
Um to be able to help hit blow him air too as far as that goes
Um, and he's been running he just ran this whole season this last year
And won the arena cross with it making all his whole shots. He's been improving his lap times by almost a second and a half
Um with and without the air filter
It's wild because back in the day I was reading an article about the yamaha vmax one of the first articles
That that really got me inspired to have one of those bikes and it was talking about
How fast the butterfly valves could open and how quick that velocity how it would speed the velocity of the air up
As it as it hit the intake and you think about, you know, just that theory and how it made more power and and you know, the old, um
The Oda
Functioning air intake hood scoops on cars how it would open up and allow
You know the air to come in straight into the carburetor and you know, these were making
You know numbers when the car was running and moving it was making a little bit of improvement
Now you take this refine it
Put it on something like a dirt bike where you're you're really instant throttle response quick responses
You you die for that if you can get that
Diled in through turns you could throw your bike into a turn really low
Skip through it and that wick that throttle. You don't have any build time
But it's right there with big power big performance a lot of air you feel that in your ride can compensate
Uh for so many things uh to speed you around that track. I imagine the dirt bike response has been pretty significant, man
Just knowing what I know about dirt bikes. I'm not gonna lie
You're still going over overcoming the part people think is a computer fan
But the people that have put it on I haven't had one person send one back. Let me put it that way
I got a 30 day money back satisfaction guarantee on all my air cleaners
But once they put it on that's when they find out that quick throttle response acceleration
They're able to come out of the berms uh in a higher gear without down shifting before they hit their jumps
They can just hit their throttle and go and they're able to maintain the third gears and stuff when they hit their jumps
Um and everything and I could totally see how that's a huge improvement. It is it's uh
That's the part where people don't get it is because back in the day they was tried
And they just it's good that's got instilled in their head that it don't work
But now with fuel injection that was back in carbureted days. We didn't you know in that time we didn't uh
Have that stuff or you know carbureted bikes are a lot different as far as the air
You don't want your fuel to bounce into each other where the carburetor would make bigger droplets
Um, so the whole point of having uh fuel injection. It's a totally different animal. Yeah the atomization. Yeah
So much more efficient and if you get more air in there, you could add a little more fuel to it
increase that atomization increase that you know timing and
Wicked off a little early get more a lot more power and better mileage to boot so
I see it making big big impacts on things like motocross things like dirt trail riding
Uh enduro riding things like that where people get significant gains out of it. You know your adventure bikes, kevin
Uh, you know guys like to go on big long rides on six fifties
In the mountains and and in the canyons. This is something that could really help in a lot of ways
Oh, definitely. Well, I think you hit it earlier, right?
The technology for fans for electric motors, right?
I mean all this cordless stuff cordless drills and all the power that you're getting
You know from a from a cordless device because of
Deficiency and the power and the density you get out of right these brushless motors. I think between like you said before
Uh, the the fan technology itself and then the right sizing it on the application
You've kind of you know found that that sweet spot that just wasn't there before
And you know, you had this, you know the two different styles of filters
So the the the v2 and the harley one, right? I mean it looks like you would think an a and filter
There's not this chunky thing somewhere like it's basically
Embedded in there and it's got some great little styling to it the way you've put it together and then the
You know the dirt bike version, right? I mean
From the you know the outside you can't tell it's just this foam
Filter just like you have in your bike, right when you flip it over on the inside of it
It's all integrated so there's there's nothing to to see there's nothing to try to you know hide from a styling perspective
It's a really clean integration
It looks like you just pretty much take your old filter off and drop this one on right pretty much exactly that every cage
I've built is made to
Bolt into whatever they their cage how it's set up
And everything so
Design wise I imagine if I'm at the starting line if I'm pushing my bike to the starting line
And some dude turns that phantom before he kicks his bike on I'm gonna be like what the what is that?
Uh
Like that's some that's some trick stuff, man
And nowadays a it advantage you can get man you take that advantage and run with it
So if you're a mountain bike a trail bike and if you're a ride any sort of dirt bike and dirt bike
Uh any of the adventure rides things like that man definitely something to look at
How do people find you say on social media if they're interested in these you know setups for a dirt?
What is it if you don't mind me asking?
What does it go for on the price of a dirt bike application? How much are these things the dirt bike applications?
The dirt bike dirt bikes are 350 dollars
The atv one is 8 850 and the harleys are 900
They all come with a 30-day money back satisfaction guarantee on them
And everything but I haven't had one person yet send an air cleaner back
And I've sold several hundred of these so far in in different countries also
Yeah, man, way cool. What a cool little way add just that extra edge if you're looking for it
And I'm not done the patent doesn't isn't just for motorcycles
It's for any internal combustion motor and it's not a design patent. It's a utility patent
So I'm not done with it. I just started cracking this egg
It if I can figure out how to uh feed these uh vehicles to feed the ones that turbo to help it on that turbo lag
Um, we're gonna be doing a lot of research and development on creating different products or different vehicles
Interesting, man. All good stuff to know and keep it up. Where do people follow you or find you on social media?
What's the best routes?
Uh, you can find us on road skulls
Um, we got a facebook instagram and a youtube channel that we got videos
My guy Jason with creation films has done a lot of informational videos and stuff to tell everybody explain to everybody
For all the questions of what we uh, we get on our air cleaner setups
Yeah, man, uh and road skulls with a z
No, it's an s with an s you always got to confirm that
Uh road skulls with an s. All right. All right road skulls with an s
Uh and one more time if they're googling it check out the straight shooter air intake
Uh really cool design
And all combined all in how many years have you spent just busting your hump for this thing?
78 years now. We've been going at it
Yeah, man, and it's it's starting to get legs now
Now, you know people are putting them on their bikes and running them and finding out the truth instead of being what social media
would have to say about it
Good man. We got to be proud
Uh, we see the best of luck and thanks for sharing a little bit of that story with us, man. All right, much appreciated. Thanks guys
Thanks for having me on yeah, man. Hey and make sure you check out our show air weekends on the motor chin network

Kevin you show up to the line with just a little bit more power a little bit more oomph out of turns and berms
Man, it's gonna make a difference on motocross, dude
It makes a big impact on that man. I'm i'm happy to see that go in that market
I think he's got a big future in that that market alone
Well, the whole game there man is to get the lightest bike you can get with enough power to rip the quarks, right?
So if you can do any kind of downsizing down waiting
You know and still have the the giddy up and go that's a win
Well next next guy we have to get on as the electric dirt bike guys
Have you seen the electric dirt bikes the starks? Oh my god. That's an ugly world. All right, man
Well, hope you guys had some fun. Hope you got to check out something cool

About this episode
Power and fuel economy get tied together through airflow-first upgrades: the hosts frame engines as “air pump” systems and compare classic “power adders like turbos and superchargers” with simpler intake changes. The guest explains how a forced-induction mindset led to a fan-assisted intake, including airflow specs and dyno validation. They also break down why dyno wide-open-throttle numbers can mislead real riding, emphasizing part-throttle behavior, throttle-blade restriction, and matching airflow capacity to engine demand—plus reported mileage gains from the Straight Shooter Air Intake.
From concept to patent to power, Kevin and Willie delve into the journey of the RoadSkulls V-Twin Performance "Straight Shooter" air intake system that represents a revolutionary advancement in motorcycle performance technology. Creator Kevin Edgmon enlightens the guys on just how his utility-patented design is making a significant impact on engine power and responsiveness, especially on motorcycles and vehicles battling turbo lag.
