damn son, i replied without really messing with that site and all the ratios. but i just did and that thing is bad ass. the calculations are true and correct, cause i carried my car to a certain high rpm _000 and was doing a certain high speed 1_ _ and the calculator was dead on. i put in the ratio of the ls fifth from a sheet i have with all my other b-16 gearings and in 5th i gained 20 mph more than the b-16 5th gear. and on a big plus it tells you what rpm you will be at at a certain cruising speed when in top gear. wow... much much respect, and big up!!! but still would like to feel how it transitions though
