I measured the gear ratio of the front and rear diffs.
I'm getting 3.75:1 maybe more like 4:1

So if i used the transmission from the gas engine that is 3.75 + the diff which is 4. That gives 7.75:1
From what I read on here, that is too low. I was told all in i want to be around 15:1

Bronsonj. Thanks for helping with the calculation method. I might try that.
I like the Navitas kits but form what i say they are rated to 5kW max. Is that gonna be enough?

My next challenge is those Worm Gearbox that i would like to use to ease the install. Those are not typically rated for 6krpm. Which the electric motors have a max rpm of about 5700.

So now i need to figure out. What rpm will i typically be spinning? This would help determine if i use the worm drive gearbox or not.
