Borg Warner EFR ::::: Borg Warner EFR Series 7670 Turbocharger

Borg Warner EFR Series 7670 Turbocharger

EFR 7670 is ideal for road racing and time attack applications, as well as responsive high power street driven vehicles. Engineered for great spool, quick response and the potential to surpass 640hp - the 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. Ceramic Ball Bearing only, watercooling recommended (not mandatory)
