Supercharged gx390 mini bike!!!!

short test run with 20psi and 17/53 gearing with the stall turned down considerably. This gearing is good for 100mph @ 8700rpm. Full pass coming soon.............

you the man. Cant wait to see this at the track

[@UnTamedMustang]

If you listen closely to the engine, he stays in low rpms nearly the whole time.
Fast forwarded? I think so.

[@chri2halty954]

no. How torque converters work is they pull low rpm until final drive that's when the high rpm comes in. Notice it starts to climb at the end

Naw not likely bro I built mine to do 72mph at 3750 rpms 87 at 4600

[@mctechmark]

Nice build! It looks as though you are running a 1:1 ratio on the drive and accessory pulleys. Did you try other sizes??

[@Chadk2001]

have you tested the bike for 20 psi or is that an estimate?
