Re: I'm lost, ignorant and out of my league, no doubt.

once in high gear and at max rpm you will travel at max mph, reducing 60 ft. times will decrease E.T. and actually could lower MPH because youll reach the timers before max mph.

Re: Launch problem

squats way to much...do you know the IC length and height?

strikes the tires so hard the wheelie bars and smacking the ground....extension setting on shocks is where?

check with the tire manufacturer if the tire matches the application.

if i spot your car at the grove sometime ill stop by.

Re: TOO MUCH TRACTION?

tuning a nitrous car without the nitrous on is impossible, the gear selected, the converter stall, even the carbs are all set to have the additional torque. all nitrous cars are pigs when run on motor and they dead hook, the additional power from the nitrous is needed to break the tires loose and ge...

Re: Big tire setup and tire shake...
