Preparation for the STILLEN supercharger

KEVTEX

The energy required to spin a compressor(turbo or supercharger) only comes from one place. That is from the engine itself. Superchargers take the power directly from the crankshaft.
Turbo's get their power indirectly from the extra work the pistons have to do, to force the exhaust past the turbo impeller.

Its only work for the engine at lower rpm, once the turbo spools up beyond inertial forces then any power loss essentially dissapears.

Unfortunatly in the case of a supercharger the faster it spins, the more power it takes to drive the supercharger.
