Daytona Beach, FL, United States (AHN Sports) – NASCAR has a new kind of two-car racing at Daytona International Speedway this Speed Weeks but due to the speeds they produce the sanctioning body is adding a new wrinkle to slow the cars down in the interest of safety.
A pressure release radiator-cap will be implemented on the cars beginning Wednesday in an effort to slow their speeds by reducing the amoung of two-car drafting.
“What we know is, we can have good races at 200 miles an hour and 100 miles an hour, and everything in between,” said John Darby, NASCAR’s Sprint Cup Series director. “I think we can all agree … that 206 is probably a little bit to the extreme side.”
Each car’s front grille, which currently measures between 100-150 square inches, but it will now be a uniform 50 square inches.
The additional wrinkle is each car’s radiator will be equipped with a pressure-relief valve set to 33 psi, which will force each driver to keep an eye on his engine temperature gauge or risk blowing the valve and losing the water out of his radiator.
It is an indirect way of trying to bring down the speeds from Saturday night’s Budweiser Shootout. The rear car in a two-car draft will have to occasionally move out of line, into open air, in order to cool its engine, thus the breaking of the draft will slow the speeds.
“The speed is the problem,” said Jimmy Makar, who runs the racing operation for Joe Gibbs’ team. “I think we’re all a little nervous about the speed. We don’t need to be running that fast.”
By possibly limiting the two-car drafting, NASCAR is hamstringing an unusual style of racing that hasn’t been universally embraced by onlookers.
“They’re all related; you don’t have the chicken without the egg,” said Darby. “All this does is, it puts a ceiling on how hot you can run. If everybody has to quit pushing when it gets to 250 degrees, that’s your limit. The world’s not broken, we just want to tweak it a little bit.”
