Description
The EFR 7670 is capable of 64lb/min compressor flow – unheard of for this size compressor wheel. The 7670 is an excellent turbocharger for road racing and time attack applications, as well as responsive high power street driven vehicles. The 70mm Gamma-Ti turbine wheel is the optimal match for the 57.2mm inducer / 76mm exducer FMW compressor wheel and is capable of 45+psi boost. This turbo uses the mid-size EFR ported-shroud compressor housing, great for fitment in cramped engine bays. Ideal for use in single turbo applications for the 400-650hp range, or as twin turbo applications 800-1200+hp.
