No offense, how many times do I have to say it, it's like you don't understand what a powerband is or why you would need to gear for it.
For the millionth time similar powerbands but operate at different rpms.
I literally wrote it down from stall to shift points for these two engines at 5 mph increments showing how if geared properly how they would be putting similar hp to the ground at each 5 mph.
