Bruce and Hales make good tire points. I still think 200 + for 9 seconds is the obvious ('Cause they did it) limit for Hoosiers or 'Cup tires. The Cup guys change them every 20 or so laps on the long tracks touching a 200
average.
Certainly the 'chute removes a lot of the heat soak into the tires from the brakes. Wonder if nitrogen helps race tires run cooler??
But I still wanna know how this produces 5+ HP/CI. A ProStock 500 inch engine makes 3.5HP/CI -but without boost. So how much boost? How do you keep the heads on? How big intercoolers? Spray??
Sorry-I love the tech and can't get it.
Bruce, will your NA GT touch 200? And what came with it-Goodyear F-1's?
