In the few months I've been driving mine, I know for a fact that the launch/first 60' is where this car really sucks at life. Although, I haven't had the brass to do a 4500RPM launch, either.
But these cars are far too light and far too hot once you get 'em rolling to be confined to the 14's until death do us part.
I think it's all in the launch, clearly. Fastest N/A time I've seen prior to this was a 14.7 and you've beaten that consistently by .3 every run... with stock paper, nonetheless. That's a testemonial to your driving skills. Most people claim that a good CAI can drop .4/.5 off your ET. Add a tune, and I see no reason why it shouldn't be good for another three tenths off the bottom line. Add injectors... you get the idea.
I still think Franc needs to hit the track... he's comfy with a 6-speed and has about $2,000 into his motor. But, he's never raced his. If he can't crack 13's, somthing's up.
