NASCAR has issued a new technical bulletin to its Sprint Cup teams, detailing major changes to cooling systems for 2012 Speedweeks at Daytona International Speedway in an effort to better regulate tandem drafting. According to Chris Paulsen, president and owner of C&R Racing Inc. — which manufactures nearly all of the radiators used in NASCAR’s premier series — the sanctioning body will be significantly reducing the size of the radiators and changing the location of the grille openings before the cars return for Daytona testing in January. “[Sprint Cup Series director] John Darby is implementing a two-gallon maximum radiator size,” Paulsen said. “So in other words, the big, huge five-gallon radiators everybody’s running will be down to two. And that accumulator can was a one-gallon max volume. It’s going down to a half-gallon-sized can.” The idea is to make the cooling systems less efficient, Paulsen said, forcing the cars to run in open air to keep water temperatures down. “We’ll probably see some result from that, but it’s not going to be huge, mainly because they’ve got these things figured out now,” Paulsen said. “But it’s still going to have an effect. The bigger effect is going to be moving the grille opening up to the bumper fascia area. Because now when they’re tucked up behind another car, they’re really going to kill all the air. So I think they’re on the right track with that. They’ll get the result that way.”
