Here is an FD3S 2 rotor on a Mustang Dyno running E85 putting 703 RWHP at 23PSI. Engine is a full bridge 13B-REW with a Cosmo upper and lower. Turbo is a Borg Warner S475 T4 housing with a 4 inch exhaust. Specially made V-Mount which feeds into a Wilson Manifolds 105mm wiggins throttle body. ECU is a Motec M84 with an M&W ignition system. The car was tuned by George Marinov at PRT Performance using their Mustang Dyno, we stopped at 703 RWHP at 23psi because we need to change out the waste gate spring in order to add a stiffer spring to up the boost. Don't think it matters since the ECU corrects for this but everyone always asks: ambient air temps were approximately 96 degrees with 53% humidity. Typical Texas weather especialy after its been raining and the sun is shinning in the summer.
