Very powerful RX8 - 3 Rotors and Turbo

Mazda RX8 with 650 BHP at the crank on the DYNO !!!!
The owner of this RX8 has recently added a turbo to the NA 20B powered 2004 RX-8. He decided to to buy a Precision T71, GTs, Billet Compressor wheel. Derrick’s ‘93 3 Rotor RX-7 (www.3rotorrx7.com) has a Precision T74 GTs and makes 525rwhp and 480 ft lbs torque @12psi. By going smaller(and Billet Wheel) he thought he would get a faster spool at the expense of some top end, but he was wrong. He was 100 hp short of my goal and the spool from the billet (heavier) wheel was slower, it has sold on eBay to the highest bidder. The good news, as he writes this on its way is a new Comp Turbo t76 Ceramic Ball Bearing Turbo
