Restrictor Plate Tracks: A Driver's Nightmare
Love ‘em or hate ‘em, or don’t know about ‘em, restrictor plates are a part of NASCAR, for now at least. Simply explained, restrictor plates are devices installed at the intake of engines to limit their power, which slows both the acceleration and the overall top speed of the car.
A more detailed explanation (for the Clint Bowyer/PEAK car enthusiast) reveals that a restrictor plate is a square aluminum plate with four holes drilled into it. The hole size is determined by NASCAR and varies between 0.875 inches and 1 inch. Restrictor plates reduce air flow and fuel into the engine's combustion chamber, reducing horsepower and speed. Got it? Good.
So why does NASCAR want to slow cars down when the purpose is to go fast? Good question. And the answer is fairly simple. Safety. NASCAR has superspeedways, which allow cars to exceed speeds of 225 mph. With this type of speed combined with other cars on the track, crashes are almost inevitable, causing safety issues for both drivers and spectators. But this notion is of much debate. Some say restrictor plate racing defeats its own purpose because it leads to bunched-up racing due to cars being less capable of gaining separation.
Regardless of the debate, NASCAR’s restrictor plate superspeedways consist of two tracks. Daytona International Speedway and Talladega Superspeedway. They are dubbed superspeedways because of their distance. Both oval tracks exceed 2.5 miles in distance. So NASCAR has ruled that all cars at these tracks must use restrictor plates.
One of these restrictor plate races is coming up on July 6th in Daytona. And as the most anticipated race of the year, this one is sure to not disappoint. For the big race, we’ll be unveiling our new BlueDEF graphics for Clint Bowyer’s #15 car. Wish Clint luck, if you see him.
So what do you think about restrictor plate racing? Is it safer? Do you enjoy watching it? Or do you think only the PEAK car should be able to use PEAK products?
