First off, we have the same motor. Prestolite MTY4001 36v stock.
Just look at these two videos

the first is with EXTREMLY grippy wide tires.
the second is with normal gokart tires.
he is running 1.16:1
Same setup in both videos, only different tires. He is running 110v 500amp open revolt controller. In other words, yes more volt than mine, ive tested 84v, but again. today i tested 48v, and the burnout WITHOUT me in the cart is the same, just less high rpm wheel spin. (spun the tires at 480amp+ with the test yesterday @ 84v and today @48v, so seems the volt doesent make any different in when it starts to spin, both at 480amp+)
I did a test today with 48v. Pushing it against the wall, i wasent in the cart, so it only had around 60-70kg load at the back tires (motor and frame). Still same gear ratio 1:1. I added a clamp meter to be sure that the data from the controller wasent wrong, and yes, they was correct, i peaked 662amp @ 48v.
It started to spin the wheels at around 480amp+.
With me in the cart it would NEVER do any kind of burnout, and the wheels wouldent spin.
The motor is wired in this way
Plus to S-1
S-2 to A-1
Ground to A-2
Brush picture. I got 8 of these.
