The new EFR series from Borg Warner combines all the latest turbocharger technologies at the moment.
With features and benefits such as:
The low inertia of the impeller ensures a fast spool.
The Gamma-Ti turbine impeller increases the response by up to 50%. Wheel sizes range from 55 to 80mm.
Heat-resistant turbine Housing.
Cast turbine housing made of high-strength stainless steel and extremely smooth internal processing for better airflow. The turbine housings have thin walls to reduce weight and thermal inertia.
Special processing of the "Superback” and “Fullback" impellers ensures very high efficiency. The "Superback" shape of the rear part of the impeller reduces centrifugal resonances and increases the speed of rotation.
The excellent response of the turbine.
EFR turbochargers use a double ball bearing cartridge with ceramic balls in a metal cage. This system provides a significant reduction in friction at low speeds and in the process helps to improve the response of the turbine.
Universal compressor housing.
The “large cover " housing has a double universal flange for connecting silicone or v-band.
The integrated compressor recirculation valve (CRV) helps to avoid the effects of "surge" and "backflow" which simplifies and reduces the cost of the entire system as a whole.
Forged milled compressor impellers (FMW).
EFR turbines use fully milled "Billet" forged aluminum wheels. Greater strength and lower weight compared to traditional casting.
A platform for installing the sensor is provided on all housings. Sensors are sold separately.
Boost solenoid valve (BCSV).
It is integrated into the compressor part and is included in all EFR series turbines.
Built-in high-efficiency Westgate.
Large built-in Westgate ports provide high throughput for serious projects.
Easy to rotate.
Simple orientation of the compressor part relative to the turbine part by means of a connection in the area of the ball bearing.
Installation and configuration is greatly simplified when using EFR turbines with integrated westgates. There are three sizes of westgates to choose from and each can be customized.
BorgWarner EFR 7064 is an excellent turbocharger for drift, road racing. The EFR 7064 provides incredibly fast promotion and response when running on stock and modified engines. The 70 mm compressor impeller has a 52.2 mm inductor and has a potential of up to 560 HP-unheard of for this compressor of this size. The low-inertia Gamma-Ti 64 mm turbine impeller is optimally suited for the 70 mm FMW compressor impeller. This turbo uses a medium-sized EFR compressor housing, perfect for installation in tight engine compartments. Ideal for use in single-turbine installations for the 350-560 HP range or in I-turbine engines with a potential of 650-1000 HP.
