What motor, turbo or supercharger. And gear ratios?? Maxed out??

Well, the best thing you can do is to tickle around with gear ratios. Do a dyno run to find out at what rpm are the peak power and torque. Then according to this data make a close-ratio (the numbers are “close” to each other so that there’s little gap between them) transmission setup. Make a long first gear and then try adjusting the each next gear so that the rpm drops down to about the level where the peak power and torque are. Tune the final drive ratio to adjust the maximum spread of each gear if the car seems too slow or tops out before the race end. That’s basically it.
