The BorgWarner EFR 7670 Turbo Is Perfect for Single or Twin-Turbo Applications BorgWarner's EFR 7670 is ideal for responsive autocross, road racing, and time attack applications. The EFR 7670 delivers an early spool with a healthy 64lb/min compressor flow, It is an excellent fit for use in single turbo applications for the 400-600hp range (up to 2.6L), or as twin turbo applications 700-1100hp. BorgWarner utilizes their 70mm Gamma-Ti turbine wheel as the optimal match for the 57.2mm inducer / 76mm exducer FMW compressor for an unmatched response. This turbo uses the mid-size EFR ported-shroud compressor housing, with a 3.5" inlet and 2.0" outlet. It features ceramic ball bearings, giving you more responsive power and extreme durability.
