Re: gearbox calculator
 

Very interesting.

I figured mechanicly shifting would take advantage of the power better, but The other curve still looks like it is pretty decent. with some more tweaking it may be possible to make it even closer. possibly running all three cims at different speeds.

It will never match a mechanical shifter, but I think it would be possible to make a reletively light, effecient, cheap, and simple "two/three speed automatic shifting" gearbox that doesn't rely on any pneumatics or programming input.

You would have to figure out how to make this work in forward and reverse though
