Thanks for the response, Jim; I appreciate it!!!
On #2, I am curious as to what the safety issue is with compressed air valve springs (or, did I get the numbers wrong?) Formula 1 cars race around CORNERS at 200 MPH and the F.I.A deems these springs as safe to use (they've been on all F-1 cars for years), so what's the problem with straight-line racers' safety isues with them? I don't understand what "safety issue" of concern is, here.
And on #3, your answer of "How do you monitor that will a tell tale?" relative to boost didn't really explain anything RE: why screw superchargers are banned. They have a reputation as being more efficient than Roots blowers, and I'm sure somebody's "blower dyno" has all the answers about how much power it takes to drive any of the popular configurations to X-pounds of boost, but the question was, "Why are they banned?" I'm certain NHRA doesn't ban them because they're inefficient...
I have my own ideas, but you having been "in the business," would have a much better idea than I would.
Thanks again for your response. Is your A/SA car a Stage III Wedge? Good luck in 2009!!!
