What is a restricted plate race in NASCAR?

Question

I hear about it all the time in the raes what does it mean

Answer 1

A restricotr plate race in NASCAR is when they place a restrictor plate on the car. NASCAR places them on the car and the teams never touch them. You can use the Wilkipedia link that the above poster gave you if you want to know more about restrictor plates.
Simple answer...it's a plate that goes in the intake of the engine and has 4 holes to restrict the air flow to the engine.
It slows the cars max speeds down. It slows down acceleration rate.
Nascar first utilized them to let teams with smaller engines (less money) have a fair shot. Then they went to the same size engine and used them for safety reasons. First at Dega and then at Daytona following some horrific crashes. They are currently used at Talladega and Daytona. They were once used in a race at New Hampshire following two very tragic deaths so closely together. The reason was thought to be a stuck throttle and the restrictor plate was used to prevent that. However, there was only one leader and the race was deemed boring with the inability to pass and off came the restrictor plates.
Rusty Wallace once hit 228MPH at Dega w/o a restrictor plate back in 2005.
If you look up past answers on Yahoo I have answered this question twice in great detail..but you can find that same info on Wilkipedia and About.Com and even Nascar.Com

Answer 2

A restrictor plate race in any of the larger tracks where they can go over 190 miles an hour because of the length of the track. They put a plate on the engine entering the carburator that has a smaller airhole than they would have at a short track which restricts airflow thus slowing the car down. They did this to ensure the safety of all the drivers because there were so many accidents and injuries going on at these tracks before the implimentation of the plate

Answer 3

they(NASCAR) have the teams place a plate between the carburetor and the intake manifold,,it has smaller inlet holes to cut the air flow,causing less horsepower in the cars,,,it also affects the acceleration of the cars on the track,,making it harder to drive away from traffic,,,in the restrictor races(Talledehga & Daytona),,the cars are always bunched up,,,they need a drafting "buddy" to make a pass on anyone,,,thats why sooooo many of us real NASCAR fans find those race tracks boring,, they are also noted for the "waiting for the big one to happen" tracks,,,restrictor plates we're brought into use in the late 1989, after Bill Elliott set some very fast race speeds qualifying and winning race's,hope this was helpful to you

Answer 4

Nope...and it is the reason it is the appropriate race at Daytona...they have about 2 hundred a lot less hp,push plenty better air,run a diverse carburetor and intake...higher spoilers too i imagine. the outcome is...compared to cup or Busch,they could develop off the accelerator and under no circumstances lose floor in case you want to position lower back and set up a run and create a Sling Shot flow to bypass different automobiles with or and under no circumstances using a pusher.as sturdy because the 5 hundred develop into,the automobiles had yet another 3 way end...i love it!!!

Answer 5

It restricts the air flow into the engine to lower the horsepower and speed. The problem is that it bunches up the cars and when one wrecks, it takes out a lot more cars.

Answer 6

a restrictor plate restrictes the amount of air that can get to the engine, making the car go slower. they do this to make it safer on some racetracks where the cars go around 200 mph

Answer 7

it's to slow down the car's from going to fast, but i don't like the restiriced plate races but nascar has there rules

Answer 8

it restricts the airflow into the carb to cut the horsepower by about 50%.

Answer 9

makes cars go slower
instead of 212 mph
they only go 190
they did it as a saftey thing
there was a bad crash one year
it may hve killed someone(i think neil bonnet)
that is why they did it

Answer 10

only at talladega and daytona beach. all cars will have equal speed. it's safer in a way but more dangerous in a way. they drive in clusters. if there is a wreck it is a big one.
