![]() If you really want to crunch numbers and have dyno sheets and your trans gear ratios, you can do it mathematically. You multiply the rear gear by 1st gear, times that by the torque at whatever rpm you want to check. do the same for second. When the value for second becomes greater than the value for first, that’s the shift point. Pretty simple, but we don’t race calculators, and the real thing is always a little different.
