I have had my scat pack for a couple months now and haven't had the opportunity to get it to a drag strip yet closest to a strip was an airport runway in the high Nevada desert for a weekend race. I'm wondering how much of a difference I can expect when I get it on a prepped track? At DA of 9500 in the desert with no prep on the runway I was able to run a 13.9 at 102 mph in 1/4 with an ugly 5.1 0-60, back in the sf Bay Area I've been able to pull down 4.5, 4.6 0-60's when playing on deserted highways and a best in car timer of 12.9 at 108. YES I'm still learning the clutch / gas peddle dance !!
