What "Country Boy" explained. Last year NASCAR decided to see and had Rusty Wallace (retired now) take a few laps at Talladega WITHOUT a restrictor plate below the carburetor. The only car on the track, he got up to 232 mph so they flagged him in. Tires won't last.

They are the two tracks on the NASCAR circuit that require the use of restrictor plates, Daytona and Talladega. Because of the size of these two tracks, NASCAR uses a restrictor plate to keep speeds down. Basically a restrictor plate is a machined steel plate that is inserted between the carburetor and the intake-manifold that reduces the size of the air hole, restricting the amount of air going into the engine. It significantly reduces the amount of horsepower the engine produces, lower the top speed of the car.

Definition: A flat device with holes drilled in it designed to limit the amount of air that enters the engine. This effectively limits the horsepower of the engine and slows the cars down.
These devices are used primarily at Daytona and Talladega.
Examples: The restrictor plates reduce the horsepower so much during plate races that aerodynamics often decide the winner instead of the engine.

Denis, A restrictor plate is a flat surface plate with holes machined in them that is sandwiched between the carburetor and intake manifold to restrict the air and fuel from entering the cylinder heads and combustion chambers.
This device severely lowers the horsepower of the engines to slow them down on the two super-speedways. Ordinarily the horsepower ranges around 820 - 830 horsepower. The super speedway motors we saw yesterday where only capable of just short of 500 hp.
If left unrestricted yesterdays cars would have been sailing along at speeds of 225 - 235 mph. Tires and driver safety is the reasoning behind slowing them down

Nascar and their insurance companies have determined that speeds above 200mph can result in race cars getting airborne and possibly landing in the grandstands. Daytona and Talledega speeds had been exceeding 200 many years ago so they require a restrictor plate between the carburetor and the engine to reduce power and speeds to below 200.

A plate that is designed to not let as much air into the engine-it saps horsepower so cars cannot reach really high speeds
They are used at Daytona and Dega

In the battle of car manufacturers, it is a way to level the playing field.
Chevy is better, no Ford, No Dodge...........NOPE! They are all restricted together to be equal. Makes no sense to me, so I don't watch. Not only do they limit what a car can do, but they place drivers on a round track taking away all driver negotiation, no braking, no hard turns, no downshifting. NO real racing as far as I am concerned.
Racing is supposed to be a test of both driver and machine, pitting each team against another. Instead, NASCAR has created a pseudo-sport where all cars are equal and drivers do nothing but get to top speed as quickly as possible and draft whenever possible.
Dull. Give me Rally anyday.
