FAS900
900 Wheel Horsepower. The Perfect Balance.
The FAS900 is where serious performance meets real-world reliability. A full fuel system upgrade, pinned crank, aggressive pulley package, and a custom tune built for 900 WHP — all calibrated and verified on our in-house AWD dyno in Punta Gorda, FL. Still street-drivable. Still pump gas.

Lower-temp thermostat maintains optimal coolant temperature during extended high-output operation.

Common Questions
- What does the FAS900 add over the FAS850?
- The FAS900 uses the same reliability foundation as the FAS850 (injectors, pinned crank, thermostat) but targets 900 WHP through a more aggressive pulley combination and a recalibrated tune. The fuel system is upgraded to support the additional demand.
- Does the FAS900 require any internal engine work?
- No. The FAS900 is a supercharger-based external build. Rods, pistons, and heads are not included or required at this tier. At the FAS1000 level, internal work becomes part of the equation.
- What fuel does the FAS900 run on?
- 91–93 octane pump gas. E85 compatibility is available as an option — ask about the FAS900 E85 variant when you contact us.
- Is the FAS900 a realistic daily driver?
- Yes. The FAS900 maintains factory-level drivability for street use. The tune is developed to be clean and responsive, not just peak-power optimized. Thousands of miles on the street is realistic at this power level with proper maintenance.
