NEW ROTAX RACING SC Impeller> COMING SOON
In about three weeks Rotax Racing will release their new supercharger impeller. Dyno testing is done and the results are fantastic.
Features:
- Lighter than stock = easier clutch life
- Almost 2 psi more boost than the stock unit!
- Fits in stock housing. no modification required.
- Adds 15 hp to a completely stock engine...even more on modified engines
- Compatible with RR ecu equipped machines( ported heads require larger injectors)
- Impeller and injectors available through me or Jerry's online store.
- No firm price yet but approx $450~475. injectors $107.60 ea
This chart shows the boost pressure during dyno runs on a completely stock engine.
