1989-93 6psi 2.1l w/ gt40 lower instake

If you plan on building a nice combination to run 6-9 psi on 92-94 octane, we highly recommend our Number 1 selling 2.1L standard kit. The BLOWZILLA 2.1L supercharger with bypass is recommended for higher boost levels (6-18 psi). Larger screw rotors raise the HP potential to 785! Standard practice is to run 6-8 psi for everyday driving and then up the octane, boost - and HP - for the weekends or racing. Truly, the best of both worlds. Every 1 psi = 10-15HP. Also great for big inch 347", 351" etc. Available in 2 basic models for '86-'93 and '94-'95 Mustangs.
Standard Inlet w/Bypass - Great or 6-18 (375HP/560 cfm) 5.0 or GT40 with 80-90mm mass air meter and 70mm throttle body. Will make 460 engine (360 rear wheel) HP but loses horsepower through inlet (see "Rear Wheel HP Comparison" below).
FLOWZILLA Inlet w/Bypass - The choice for maximum performance (up to 785HP) because of unrestricted FLOWZILLA inlet. Must use 80-90mm mass air meter and 70-75mm throttle body for optimum results i.e. minimum inlet restriction
