355WHP Scion FR-S on GTX28 Turbo and E85
What was a relatively stock FR-S was completely transformed with high performance upgrades including Garrett GTX28 turbo kit and supporting modifications. We installed the billet-wheel turbo kit and full exhaust system, as well as larger injectors, fuel pump, and an upgraded ACT clutch and flywheel package. With the right performance parts, this FR-S was ready to hit the dyno.
Using EcuTek, Hal managed 264whp on 93octane gas from the high compression FA20 engine. With E85 in the tank we increased boost to 13psi and dialed the tune in to 355whp on our Dyno Dynamics. On a Dynojet this would be 300WHP pump gas and 400WHP E85.
