Dodge Dart

"Kevin's waiting there patiently 72 Dodge Dart. And a question about what Kevin? Kevin, welcome back. What's going on with this car?"

The Dodge Dart is a small car made by Dodge, popular in the 1970s. The 1972 version is known for being reliable and easy to maintain.

Term

octane

"Do you have any recommendations there? Octane?"

Octane is a rating that tells you how well a fuel can handle pressure without causing problems in the engine. Higher numbers mean better performance for powerful engines.

Term

compression ratio

"Well, it's supposedly 10 to 1 about the car, and they say 10 to 1, but when I do a compression test on it, I'm about 225 pounds per cylinder."

The compression ratio tells you how much the air and fuel mixture is compressed in the engine. A higher number means more power, but it might need special fuel.

Term

compression test

"Well, yeah, but you see compression, a compression test, compression, pressure, and compression ratio are two different things."

A compression test checks how well the engine's cylinders are working by measuring the pressure inside them. If the pressure is low, it might mean there are problems.

Term

flat top piston

"And then the other question is if it's a 10 to 1 compression, is it a flat top piston? Does it have a dome to it?"

A flat top piston is a type of engine part that has a flat surface on top. This shape helps the engine run better and can affect how powerful it is.

Term

horsepower

"...I said I wanted 500 horsepower on the street, and I don't want to have to work on it..."

Horsepower tells you how powerful an engine is. The more horsepower, the faster and stronger the car can go.

Term

torque

"...it makes 400, and I think it's 490 foot pounds of torque at 5200 RPM..."

Torque is how strong an engine is when it starts moving. Higher torque means the car can accelerate faster and pull heavier loads.

Term

quarter mile

"...run 93 and go to the track and measure it in the quarter mile..."

The quarter mile is a distance used in racing to see how fast a car can go. It's a popular way to test how powerful a car is.

Term

automatic transmission

"...at least it's the consistency of the automatic, right, which is a whole lot better..."

An automatic transmission is a system in cars that changes gears for you, so you don't have to do it manually. It makes driving easier, especially in traffic.

Brand

Sonoco

"I either run, and like I said, I either run Sonoco 93, and if I can't find a sonoco, I'll use Shell, whatever their high octane stuff is..."

Sonoco is a brand that makes gasoline, including special types for racing cars that need higher performance.

Brand

Shell

"I either run, and like I said, I either run Sonoco 93, and if I can't find a sonoco, I'll use Shell, whatever their high octane stuff is..."

Shell is a company that sells gasoline, including special types that are good for fast cars.

Term

stall converter

"What stall converter did you put in this car? I remember this car. Now you're talking to me about 2800."

A stall converter helps your car accelerate faster by letting the engine spin faster before it actually moves the car. It's like a way to get more power when you start driving.

Term

stall speed

"The original hot rod black run, black one ran a 40 200 stall speed converter. It was the nuttiest thing I ever put on a street car."

Stall speed is how fast your engine can spin before the car actually starts moving. A higher number means you can get more power when you start driving, which is good for racing.

Term

detonation

"I'm just worried about the kind of running good, you know, detonation and stuff like that."

Detonation is when the fuel in your engine explodes too early, which can make a knocking sound and hurt the engine. It's something you want to avoid for a smooth ride.

Term

drag racing

"...they're like, where's all the drag racing? I'm like, yeah, there is no drag racing in this movie..."

Drag racing is a race between two cars that go straight down a track to see which one is faster. It's all about speed and quick starts.

Concept

hot rodding

"...it's the idea of hot rotting. And sometimes I think we're like the last Jedi. Right. You know, it's like Star Wars..."

Hot rodding is when people take older cars and make them faster and more powerful by changing parts and adding modifications. It's a fun way to express creativity and love for cars.

Term

high beam switch

"...we had the high beam switch on the floor. Right. Yeah. We had the high beam switch on the floor..."

The high beam switch is what you use to turn on the bright lights of your car when you need to see better at night. In older cars, it was a pedal on the floor instead of a lever on the steering wheel.

Term

carburetor

"...about Kevin in his hot rod what he's doing what he's going through dialing in in the carburetor and jetting. When we did that as a society..."

A carburetor helps engines get the right mix of air and fuel to run properly. It's an older technology that has mostly been replaced by newer systems in modern cars.

Term

350 automatic

"Okay it's 350 automatic with the quadrujit carburetor."

The 350 automatic is a type of engine and transmission combination often found in Chevy cars and trucks, known for its reliability and power.

Term

purge valve

"I think it was the early 80s when the purge valve problem happened when they put the purge valve up on top."

The purge valve helps control fuel vapors in the car. If it doesn't work right, it can cause problems with how fuel gets to the engine.

Term

choke flap

"this is why I want you to be able to get to the top of the choke flap to look at it..."

The choke flap is a part that helps the engine start when it's cold by making the fuel mixture richer. It helps the engine run better until it warms up.

Term

main jets

"that's how they drilled the ports for the main jets and then at the factory they just dripped some solder in there..."

Main jets are parts inside the carburetor that help control how much fuel goes to the engine when you're driving fast. They help the engine run smoothly.

Term

float bowl

"Well 50 years later those solder plugs have rattled loose and they're draining the float bowl and that's where your fuel is coming from and you'll never see it."

The float bowl holds fuel in the carburetor and helps keep the right amount of fuel available for the engine. It works like a small tank that fills up and stops when it's full.

Term

needle and seats

"If you determine that it's not flooding over the top and it's not dripping past the needle and seats such as the fuel is boiling because fuel fuel today is very different than it was in 1975."

Needle and seats help control how much fuel goes into the carburetor. They make sure the fuel doesn't overflow and keeps the engine running well.

Term

fuel boiling

"As long as we know the carburetor is for lack of a better way to say it mechanically sound and not boiling over through the throat."

Fuel boiling happens when the fuel gets too hot and turns into vapor. This can cause problems for the engine because it needs liquid fuel to run properly.

Term

solder plugs

"The only other place that fuel can be coming from is out of the solder plugs in the bottom of the carburetor and you're going to take the carb out you're going to just leave it on the work bench."

Solder plugs are used to close holes in the carburetor. If they get old or damaged, they can leak fuel, which can cause problems with how the engine runs.

Car

Kia Rondo

"Well it's a 2008 Kia Rondo and it is only a hundred five thousand miles on it and it's not a lot of miles considering it's a 2008 but the air conditioner has broken down three times."

The Kia Rondo is a type of car that's good for families because it has a lot of space inside. It's not as common as other cars, but it was made to be practical and useful.

Part

compressor

"the first time was in 2018 it was the compressor and the second time was twenty twenty three and it was the evaporator and now it's the compressor again"

The compressor is like a pump for the car's air conditioning. It helps make the air inside the car cool when you turn on the AC.

Part

evaporator

"the first time was in 2018 it was the compressor and the second time was twenty twenty three and it was the evaporator and now it's the compressor again"

The evaporator is a part of the car's air conditioning that helps cool the air inside. It takes heat out of the air so that the AC can make it nice and cool.

Car

Plymouth Valiants

"...s for the low and the high ones the pacifists the valiants for the optimists and the pessimists the ones who..."

The Plymouth Valiant is a small car that was made a long time ago, from 1960 to 1976. It was popular because it was affordable and practical for everyday use, and it helped start the trend of smaller cars in America.
