BorgWarner EFR 7670 Turbo
Click To Enlarge

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)

Wastegate Info: All EFR Internal Wastegated turbos come standard with a medium boost actuator for boost levels of up to 16psi. For boost applications above that will need to add the High Boost actuator. Use the option tab to add it to the order.

V-Band Discharge Flange/Clamp: All of the EFR Internal Wastegated turbos use a special BW Vband flange/Clamp that is not a standard V-Band. The Down Pipe V-Band Flange and Clamp are not included with the turbo. Use Option tab to add them to the order.
