NASCAR Makes Changes To Eliminate Two-Car Tandems

NASCAR has made two technical changes to limit the two-car drafting that was prevalent in the Bud Shootout, according to The air inlet for the cooling system will now be 2 1/2 inches tall by 20 inches wide, and the pressure release valve on the water system will be set at 33 pounds per square inch.

These two changes are meant to make the car overheat if two cars run in tandem for too long. Robin Pemberton, NASCAR’s vice president of competition, said:

[These changes] will bring down the temperatures so the teams can’t run at 290 or 300 degrees [without overheating] on the extended push of 30 or 40 laps. This will put [the water temperature in the engines] back in the 250-degree range.

At this point, NASCAR has not changed the size of restrictor plates, but that still remains an option depending on what the sanctioning body sees during Wednesday practice and Thursday during the duels.
