On the Nascar race Saturday nighted, they said it was a "restrictor plate" race? What does that mean?

Answer 1

the air intake on the furl injection system has smaller holes in it. it makes the car burn fuel slower, thus the speeds are reduced

Answer 2

WOW! If u don't know that, u must be new to NASCAR. I explained this to my one friend in an email. It was long enough to be a book! I'll try to sum it up. It's a square piece of metal with four holes in the middle. NASCAR puts one on each driver's engine. This cuts down the amount of air that gets to the engine by about 50%. That makes the cars go a little slower, so instead of going 215 m.p.h. & crashing every where, they go about 180-200 m.p.h. Then, when there's a resticter plate on the engine, the drivers have to bump draft, I'll just assume u don't know what that is either. Okay, 2 or more cars get together, bumper to bumper in a line, that's drafing. Now, the drivers can also carefully bump the car in front of them to help both cars go faster. If there are 5 cars drafting on the inside of a restrictor plate track (Daytona & Talledega) & 10 on the outside of the track, drafting, then chances are the line of cars with more cars will go faster & move ahead, in this case, the ouside line. There, that's restrictor plate racing & bump drafting in a nut shell.

GO Dale Earnhardt Jr.!!!!!!!! # 8!!!!!!!!

Answer 3

Pretty much what everyone else said above is correct. A restrictor plate is the common name, but it's also considered to be an air restrictor and that names pretty much sums it all up. It is set to to reduce overall speeds and also decrease speed acceleration. There are mixed feelings on them. The theory is that they are for safety, b/c of the high speeds they would hit w/o them, but some believe that the tight bottlenecking of traffic, esp on restarts causes more problems. Many feel that it makes for better competition too.

It is used all over in motor vehicles, but in Nascar it is used at Daytona and Talladega Superspeedways, b/c of their sizes. Without it one time Rusty Wallace tested at like 235 MPH at Dega.. Originally it was set in place to reduce engine size, hence giving smaller, less wealthy teams the chance to compete against the other teams. That ended in the mid 70's when Nascar went to smaller engines period. The second reason it became instated was obviously for safety reasons. The 1987 accident of Bobby Allison is what set it in full swing. In 2000 after two of the sports most memorable tragic deaths it was utilized shortly (one race if I rememer correctly) in New Hampshire to help lower the speed coming into turns. Both of those accidents were thought to be b/c of a stuck throttle and the plates were to help reduce that. However, the 300 was deemed boring, b/c it was led all by one person, and there was no passing so Nascar removed them and went back to the two track usage. As the user above mentioned tehy are issued by Nascar and installed by Nascar. The team never touches it. Also, the winning plate is then removed from the circuit.. So for example, the plate in Tony Stewart's car will remain in NASCAR piles of stuff forever.

Answer 4

they put a plate on the carburetor that has smaller holes for intake than normal. the difference is only .58 mm but it keeps the car from being able to go too fast. On a restrictor plate track the cars were going upwards of 200 miles an hour and there were too many drivers getting hurt.

Answer 5

If you don't know what a restrictor plate is then you must be new to NASCAR. Everybody else explained it pretty good. Glad to see more fans getting interested in NASCAR. Due some research and get to know everything you can about the great sport. NASCAR.com is a great web-site for info.


GO JR !!!!

Answer 6

all of the above answers are correct, but I want to add one item. The restrictor plates are handed out by NASCAR, and are installed with the inspector looking on, the sealed.

Answer 7

A special carberator(sp) plate with smaller holes restricts the flow of fuel into the engine resulting in slower speeds. This has 2 results; 1)- speeds are slower with less chance of a car becoming air-borne, but 2)- it keeps the cars bunched up longer and results in THE BIG ONE- a multi-car crash usually happens. NASCAR does this at Daytona and Talladega

Answer 8

in layman's terms the engine will not go as fast as a regular nascar engine, this keeps the bad wrecks at a minimum, the 200 plus mile per hour days are over with!

Answer 9

THERE IS A PLATE UNDER CARBURETOR OF ENGINE, IT HAS 4 HOLES DRILLED IN IT. AT A RESTRICTER PLATE RACE TRACK WHICH WOULD BE DAYTONA AND TALLADEGA. THE 4 HOLES IN PLATE ARE DRILLED SMALLER TO ALLOW LESS AIR AND FUEL IN ENGINE.THUS REDUCING THE AVAILABLE HORSEPOWER THE ENGINE CAN MAKE. MAKING FOR SUPPOSEDLY SAFER RACES FOR BOTH DRIVERS AND SPECTATERS.
