Modified fuel injectors of 75-lb/hr are Evolution-specific components used for all '11-'12 Mustang supercharger applications. According to Fred, the Boss’s OEM 47-pound squirters can’t support horsepower beyond mid-500s at the rear wheels, and 80-lb/hr injectors are too big. With an otherwise-stock mechanical-returnless fuel system, the Evo injectors maintain static 55-psi fuel pressure, without surging or other idling issues. We’re testing the blower using VP Racing Fuels' C-16 race gas and also installing Kenne Bell’s Boost-a-Pump as part of this project. Enhanced fuel octane and pressure are insurance against detonation when boost increases.
