About this episode

Bill Goldberg and DeAndre trade garage stories and build plans, starting with a cautionary tale: race fuel sitting for years can go bad without the right detergents/stabilizers, wrecking drivability in Goldberg’s Cobra and forcing him to dilute, idle, and drive it out. They then geek out on Goldberg’s 1970 Trans Am track car—built from a mix of top shops, powered by an LS7, and nearly ruined by a simple panhard bar install oversight. The conversation expands to a supercharged farm-truck-style project (Whipple + manual swap) and ends with Porsche event/value talk and upcoming racing weekends.

Technical Too Afraid to Ask
Term

detergents

"It doesn't have the detergents and stuff in it. It doesn't have the stabilizers, the detergents, doesn't have any of that stuff that we get"

Detergents are additives in gas that help keep the engine clean. Without them, the engine can get gunkier over time, which can hurt how it runs.

Term

stabilizers

"It doesn't have the stabilizers, the detergents, doesn't have any of that stuff that we get"

Fuel stabilizers are chemicals that help keep gasoline from going bad when it sits. Without them, the fuel can turn into sticky deposits and make the car run badly later.

Term

race fuel

"I poured some fricking race fuel in the Cobra, and man, it did not like it, like, by no means. And it only sat there for probably, I don't know, two years?"

Race fuel is a special kind of gasoline made for racing. It can be formulated differently than normal gas, so a street car might run poorly on it or not behave the same over time.

Brand

Costco

"I remember years ago, there was a big change where Costco was really getting into the fuel thing and building out more gas stations, but their fuel was crap."

Costco is discussed as expanding into fuel retail by building more gas stations. The speaker’s anecdote suggests Costco’s early fuel quality was inconsistent, highlighting that “same pump” gasoline can still differ by supplier and additive package.

Car

Ford Mustang

"And I put it in a 65 Mustang and it ran like shit. And then at some point over the years, you know, this could be 20 years ago, I can't recall exactly."

They put a certain gas into a 1965 Ford Mustang and the car ran badly. It’s an example of how different gasoline blends can change how an older car behaves.

Term

racing fuel

"Like we need to be, you know, the right tier fuel compete with everybody else... But yeah, it comes down to and light, your racing fuel, like light, heat, how you store it..."

Racing fuel is special gas made for performance engines. It’s meant to burn more reliably when the engine is hot and working hard, so it doesn’t “knock” or lose power.

Term

carburetor

"And I mean, that carburetor doesn't like it and it throws so much futile in there that it's like a rush of really shitty whiskey or something."

A carburetor is the part that mixes fuel with air for the engine. If the fuel isn’t right, it can make the engine run rough or spit out bad combustion.

Concept

SEMA

"it was staged out front of SEMA. You and I were out there. And then you had a little accident with this little, yeah, I was at El Toro doing Optima"

SEMA is a huge car show focused on aftermarket parts and custom builds. If a car is staged around SEMA, it’s usually because it’s a big deal to the performance community.

Term

spacer

"And so we were going to spacer, right? Because of the width of the wheel on one side. And we were going to spacer on the other side, you know, which you don't want to be doing that."

A wheel spacer is a thickness added between the wheel and hub to change wheel offset and track width. While it can correct fitment or stance, it can also create new issues (like stress on bearings/bolts) if used to mask a deeper alignment or suspension problem.

Concept

display engine

"You could just clean it up and have a display engine or, or even paint it before you rebuild it and just have a pretty cool display engine on it."

A “display engine” is an engine that’s kept mainly to look cool, not necessarily to drive the car. People clean it up and make it look nice for showing off.

Term

valve covers

"There's a few things, you know, maybe change the valve covers if they're rusted or a little bit. Cause I saw a little bit of rust, I think in the photo."

Valve covers are the top covers on an engine that help keep oil inside. If they’re rusty, swapping or cleaning them can make the engine look a lot nicer.

Concept

period correct

"I mean, I'd love to make it completely period correct looking right now and have it as a, you know, a placard in the middle of the fricking garage."

“Period correct” means you try to make it look the way it would have back when it was new. It’s more about the right look and details than adding modern stuff.

Term

crate engine

"I mean, I've got, you know, the 170 engine in a crate. You can't see it. Right. And so it'd be nice to have this as a display."

A crate engine is an engine you can buy and install without building it from scratch. It comes packaged like a kit, so it’s easier to get running again.

Concept

port the heads

"...am I going to rebuild it and we're going to port the heads? What are we going to do?"

Porting the heads is when a shop reshapes the inside openings in the engine’s head. The goal is to help air and fuel move through more easily so the engine can make more power.

Concept

machine work

"That usually requires some machine work too. You, you know, so you probably have that sent out, but."

Machine work is when a machine shop uses precision tools to make engine parts fit correctly again. It’s often needed after tearing an engine down so everything seals and runs right.

Term

bedliner

"But this is the one that has like the, the bedliner all over it. You know, so it's, it's meant to, to be thrashed a little bit more."

A bedliner is a protective layer inside the truck bed. It helps keep the bed from getting damaged when you haul stuff or use the truck rough.

Term

PPF

"you know, it's PPF and it's ceramic coated and it's, you know, like there's only so far you can take it."

PPF is a clear protective film that you put on the paint. It helps protect the truck from small damage like rock chips and light scratches.

Concept

show truck

"When I bought this truck originally, it was a show truck. I swear to you, it was absolute."

A “show truck” is basically a truck that’s meant to look great, like for events or photos. Later, they used it for something rougher where looks mattered less.

Term

body panels

"...you're not worried about like, oh, that I just cave in like an original door piece because we've done body panels on the car. We're not too worried about the fitment of things..."

Body panels are the exterior sheet-metal or composite parts that form the car’s outer surfaces (doors, fenders, quarter panels, etc.). In a track-focused build, replacing body panels is often part of the normal repair cycle after impacts.

Term

weak links

"...you got to do a couple of the weak links on it."

“Weak links” are the parts that can’t handle the extra stress. When you make a vehicle faster, those parts may break first unless you upgrade them.

Concept

NHRA

"NHRA, the Winter Nationals. So I'm going to head out Sunday to Pomona."

NHRA is the big organization that runs drag races in the U.S. If you hear NHRA, it usually means a real, official drag-racing event with set rules and categories.

Brand

Porsche

"It's crazy. ... It's, it's no secret what Porsche is, you know, the attention Porsche has been getting the past, you know, I want to say several years, but maybe a little longer than that."

They’re talking about Porsche and why people have been paying so much attention to the brand. The idea is that Porsche started allowing more personalization, which made more fans and builds show up.

Concept

customization

"I think what it is, is, is when Porsche started to embrace the customization, the personalization of the cars, not, not just, you know, like instead of going, we make a Porsche 911, you know, you shouldn't touch it."

Customization here refers to allowing owners to personalize their cars beyond factory configuration. In the Porsche context, the speaker argues that embracing modified builds helped the brand connect with the enthusiast community.

Concept

computer access

"... because Dodge was like, you can't get into our computer."

The speaker is talking about whether people can access the car’s computer to tune or change things. If a brand restricts that, it can make modifications harder for shops and owners.

Brand

Dodge

"but like once you turned it into a commercial business, it was frowned upon by Dodge. So until Dodge finally embraced it and said, we, we were back."

Dodge is the automaker behind the Charger and Challenger, and the speaker credits Dodge’s stance as a key factor in whether tuning solutions were accepted or discouraged. The segment suggests Dodge eventually “embraced” the aftermarket/tuning ecosystem.

Brand

Magnus Walker

"Guys like Magnus Walker, who's been a fan of modifying his cars and personalizing his cars... Instead of going, we don't talk to him because we don't like him messing with our stuff."

Magnus Walker is a famous Porsche fan who builds and personalizes cars. In this discussion, he’s used as an example of someone Porsche culture has welcomed.

Company

Bring a Trailer

"They pop up on bring a trailer and Grand Ray Hall performance and they're a million, million, 1, million, 2..."

Bring a Trailer (BaT) is an online auction platform focused heavily on enthusiast and collector cars. The segment uses it as an example of where these high-value Porsche-related cars show up and sell.

Concept

right time to sell a car

"So there's never, you know, you, when is the right time to sell a car? [2576.5s] In most cases, it's is hold it as long as you can. [2579.8s] So the answer to that is, is what it's the right time for you."

This is basically asking when you should sell your car. Sometimes waiting longer helps the price, but the “right time” is different for everyone depending on their needs.

Car

Porsche 935

"So the value of that nerd 935 has probably gone up enough to cover what all those mirrors would be going for today... one of the most famous Porsche racing cars was the Apple computer Porsche 935"

The Porsche 935 is a famous Porsche race car. People love it because it’s a serious track machine and also a big collector favorite. The hosts are saying this specific 935’s value has probably gone up a lot.

Concept

Laguna Seca

"since he's had that car raced at multiple times at Laguna Seca, uh, you know, uh, the Duke of Richmond flew it to Goodwood"

Laguna Seca is a well-known race track in California. It’s challenging, so if a car has been raced there, it usually means it’s been proven on a real course. They’re using it to highlight the car’s racing background.

Concept

Goodwood hill climb

"the Duke of Richmond flew it to Goodwood, you know, so we can get it there on time and race the hill climb with that thing."

Goodwood is a famous UK motorsports venue. The hill climb is a timed event where cars drive up a steep course, and it’s a big deal for special or historic cars. They’re saying the car was flown there to compete.

Concept

livery

"we have it in the Paul Newman Hawaiian Tropic livery, but the Apple car, and we've always talked about the second, you know, phase of this car"

A “livery” is the car’s paint and sticker design—its overall look. It can be tied to a specific team or sponsor. Changing livery usually means more than just repainting; it can require matching decals and body details.

Part

fiberglass or carbon fiber

"we probably got a like handmade kind of fiberglass or carbon fiber, like one or two of the missing body pieces."

Fiberglass and carbon fiber are materials used to make lightweight body parts. If you’re missing panels, using these materials can help you rebuild the shape, but it still takes careful craftsmanship to make everything fit right.

Concept

project car

"Adam, it's got to get us, you know, it's got to, like any of these projects, my projects, your projects, got to get the time, the energy, the money, you got to get everything lined up to do it."

A project car is a car you’re working on for a while. It usually needs repairs or upgrades, and you have to plan the time and money to make it happen.
