Ray-jay builds super charges for AirCooled (aircraft engines & the
corvair engine, had a corvair turbo, had a Piper turbo lance) but you
don't want one. You need a forged steel crank and forged pistons which
you don't have. Turbocharged aircraft engines only have a half life
before required rebuilds of the non-turbo engines.
Slow down enjoy the scenery.
