If engine turns at 22.000 rpm, and the gear ratio was 2.2, divided by internal ratio(IR) "2" so the wheel rpm(W) will be 5000rpm.
Im sure the 2spd shaft was turns at 2500 rpm.
To achive the same W value (5000 rpm), but to reduce the shaft rpm the IR must be in higher than 2, says it will be 2.5. So the shaft only turns at 2000rpm. Must use 1.76 gear ratio to compensate that.
Now, we gain same performance but with slower 2spd shaft rpm.

Im not sure about my math
Am I right??
