It doesn't have the exhaust velocity to spin a turbo. Plus, a Briggs head doesn't flow very well, so it wouldn't be very efficient. That Yamaha put out tons of exhaust pressure, and it still didn't spin the tiny turbo very well...

Besides, you need to get out of Briggs and move up to two stroke anyways. Twice the HP, twice the RPM, and you only have to rebuild them once a season...

 

arent enough races in Va for shifter karts...
