Borg Warner 7670 EFR Turbo, 375-650 HP. Borg Warner 7670 EFR Turbo is an excellent turbocharger for drift, road racing and street driven applications. The 7064 delivers incredibly fast spool and response while working well on stock and heavily modified engines. The 76mm OD compressor has a 57mm inducer and at 65lb/min max flow - there is potential for 650hp - unheard of for this size compressor wheel. The low inertia 70mm Gamma-Ti turbine wheel is the optimal match for the 70mm 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 375-650hp range, or as twin turbo applications 750-1300+hp. Ceramic Ball Bearing only, watercooling recommended (not mandatory).
Borg Warner's latest release, the EFR (Engineered for Racing) Series turbochargers. EFR is currently the most advanced turbo of its type engineered for the performance aftermarket. Crammed full of attributes that appeal to the performance car enthusiast, EFR is at the pinnacle of what can be done with the current state of the art.
The EFR line of turbos was born out of an internal BorgWarner Turbo Systems program labeled Advanced Aftermarket Products or AAP.
The program was engineered by a cross-functional team that began with the proverbial clean-sheet of paper. No legacy products, no preconceived notions of what a turbo could or could not have; no restrictions. The aerodynamics for the product line were selected using a range of optimized combinations that would give users turbo solutions anywhere between 250 and 1000 horsepower capability per turbo. Next, a list of every notable design characteristic for an engine boosting device was tabled. Specific interest was given to new ideas that had never been formed in metal or had never been combined into an aftermarket turbo.
The result is the new EFR (Engineered for Racing) line of turbos from BorgWarner. These turbos contain a bevy of key attributes such as Gamma Ti turbine wheels, dual ceramic ball bearing cartridges and investment cast stainless steel turbine housings. Collectively, those features help give the EFR line its innovative appeal and will provide a breakthrough experience in durability, device responsiveness and installer/user satisfaction.
