OK so say I make peak power at 5500 so about 325 to 350 hp and add 50 - 75 hp shot of Nos for a 400 hp engine. So say now I got to shift and cross around 6000 rpm so replace everywhere I said 2.94 gears with 2.76 gears. So end result would be like a powerglide with 4.25 gears.
i agree with rocco's sentiment above, shifting right before the finish line isn't gonna help you. Im curious, why are you so dedicated to shifting before the finish line?
