Thanks to all of you for the answers. That 18,000 to 20,000 RPM range was just mind boggling to me. I knew they had to have some kind of trick stuff for valves and such. I also heard them mention what one of the gear boxes cost and it was out of sight.
Ken,
Thanks for taking the time to tell me what you did. I watched them interview one of the older drivers back from before all the turbo charging and everything, and he had taken a test drive in one of the cars that ran in the class he used to. I believe his statement was, Thank God I didn't have to drive that much power and so fast. He said that when the power kicked in he almost lost control of the car. All interesting to me as I have never even sit in one of those type cars, let alone driven one. Now if I could just get one to make one run through Redding.
