jp99gt Posted September 24, 2003 Share Posted September 24, 2003 For any regions running time trials, I have a question about rating the exhaust components for points. The rules mention catbacks, and aftermarket headers, but make no mention of aftermarket H- or X-pipes, with or without high flow cats. Has anyone addressed this, and for the national folks reading this, how about a clarification in the rules? Quote Link to comment Share on other sites More sharing options...
wm577 Posted September 30, 2003 Share Posted September 30, 2003 I noticed the rules are not quit complete yet myself. There is no mention of things like: light weight flywheel, small batteries or no battery at all, min height of cars, removing sun roof (weight reduction), performance suspension bushings, aftermarket mass airflow sensors, bigger throttle bodies, ect... I think that someone with a coil over set up for the street 300ish lbs/inch rates, should get +7 points, were someone with race springs 650+ lbs/inch should get the full +9. But I’m just rambling about the rules I’m sure the rules will get better as TT grows. Quote Link to comment Share on other sites More sharing options...
NASA Jim Posted October 1, 2003 Share Posted October 1, 2003 TT is based on the NASA-X autocross system. I think a key part of it was to keep it simple. However, this is the place to suggest rules changes. There isn't really a TT Series director, and a lot of things will vary by region, but we are always open to suggestions. John Lindsey and are are probably the ones to talk to... his user name is JWL. -Jim Quote Link to comment Share on other sites More sharing options...

Well, I think there'd need to be a sliding scale for spring rates, not a fixed amount because the spring rates vary greatly from vehicle to vehicle and their effectiveness depends on the design of the suspension. But I could see how there should be levels and not just all or nothing. I don't recall if there is a rule about TT cars needing to be street legal... if they were then maybe it would be self enforcing because no one would want to drive a 650lb/in sprung car on the street Quote Link to comment Share on other sites More sharing options...
