Description
 

Our Stage 3 upgrade was developed for our customers who want to run 10 second quarter mile times and beyond supercar levels of performance!

The Stage 3 power upgrade for the ISF Supercharger kit achieves 650whp on e85 fuel (about 760hp at the crank @ e85 content of 70-80%). Internally stock ISF engines are recommended to run 50% e85 blend or higher for maximum safety/reliability.

Stage 3 upgrade kit includes:

  • Upgraded supercharger pulley
  • Upgraded crank pulley
  • Innovate Motorsports e85 gauge
  • Upgraded Bosch port fuel injectors
  • Fuel surge tank with integrated fuel pressure regulator
  • Radium surge tank with TI Automotive fuel pump
  • All fittings required for fuel system installation
  • Teflon lined braided fuel hose
  • Revised ECU tune as well as base maps for external fuel computer for pump gas, e50 blend, and e85.
  • Upgraded port fuel injectors (necessary for power levels over 600 whp)




  • Please note that running on regular high octane fuel will require switching the tune file. Running on regular high octane fuel without 55% ethanol is not recommended at full throttle. Also, using the upgraded pulley may void the Rotrex warranty.
