What carb size? I'm building up a '06 Corvette LS2 for my Panoz road race track car and need a little advice on carb size. Acceleration off the turns is the most important feature, of course top end power is also needed, but pulling off the turns is most important. The motor is a stock '06 Corvette, running a TR3550 5 speed and a car weight of 2500lbs.
Any help?

This should get you in the range you need.

Just so you know...there are quite a few people that believe you should run considerably larger than what is recommended on the calculator.

Carb Thanks for the calculator. Interesting answers, as a test I put in my current engine spec, 392W stroker, 6500RPM max and the 100% answer was 710cfm and the 85% answer was 625cfm or so and I currently run a 750HP and the engine pulls like a tractor with a Vic Jr intake from 2500RPM on the track. From 4000RPM on up it really cranks. So I'm with you that we should spec out a larger carb than the one the calculator specs out.
Thanks for the time.
