stick racers-flywheel inertia and gearing???s

[rickster]

i have a 33-3400# 69 camaro that is a drive to the track street/strip car,motor made 752hp at 6400 and 670 ft lbs at 5200,548" pump gas bbc,the trans is a g-force 101 4 speed [2.98 first],i have 4.29's out back,32" tire with double adj coilovers and ladders.just got the car to the track last week,best pass after finding a decent clutch tune [10.5 sintered],10.05 at 135 with a lousy 1.43 60'er,1/8 mile is 6.42 at 109+

i launch the car at around 6000,and it quickly pulls the motor down to around 4000,and obviously struggles to recover,except for those runs with clutch or tire spin,which don't help the 60' much

i will go as far as a 4.71 rear gear as i can still go 60 on the highway and only turn 3000,and turn 6800 IF i ever get 137 mph in the traps

does anyone have a good simulation program that will tell me what 60' improvement can be had with this gearchange ???

also,can switching to a steel flywheel with more stored energy keep the rpm's from dropping to 4000,or is the effect really only good for a few hundred rpm's????

thanx
