I was shooting for 52k rpm. I went with a 33 cout tooth on motor vs 18 on the supercharger. I am looking for a good uplift in my 6.2l. I put the e85 conversion on it and tuned it to 450 rwhp. I ran it on the track and got 11.9 1/4mile without supercharger. I just wanna be in the 10s. Anyone know what speed i neet to turn the turbine? My hobywing spins 28k at 300 amps.This is what I bought. 325-5M-25 HTB Timing Belt | 325mm Length, 5mm Pitch, 25mm Width, 65 Teeth and 320-5M-25 GAS SCOOTER DRIVE BELT MOBY SX / X / S 23CC 25CC 26CC 33CC 43CC 45CC, I will buy mcmaster car belt. The motor pully is fine but maybe not with T5.
