I am familiar with the formula that calculates predicted RPM for given tire height. Have also calculated (predicted) converter slippage for new converter. I would like to cross the finish line between 5800 and 6000rpm. The unknown factor is adding a 250 shot of nitrous. The converter was built for the nitrous and should be very tight, shooting for 3200 on motor and 4000 to 4200 on the gas. What tire would you experienced nitrous users choose?
130 mph on motor
T-400
3.73 gear
Max size I can use...30" / 10.2" wide
Should I wait and see what the converter does before purchasing tires in case the converter is a little too tight or loose? Thanks
