BorgWarner EFR 7670

The BorgWarner EFR 7670 turbocharger is designed for more serious projects targeting 400 – 650 HP, while maintaining the excellent responsiveness characteristic of the EFR line. This model is a frequent choice for powerful street builds, time attack, drift, rally, and endurance applications where high efficiency and reliable boost delivery across a wide RPM range are required.

Features:

Turbine wheel made of Gamma-Ti (Titanium aluminide) – extremely lightweight for its class, allowing for faster spooling and less turbo lag

Compressor wheel with a diameter of 76 mm (FMW – Forged Milled Wheel) with high flow and improved efficiency maps

Ceramic ball bearings with dual rows – high durability, minimal friction, stability at high boost pressures

Integrated blow-off valve, boost solenoid, and port for compressor speed sensor – simpler and cleaner installation

Turbine housings available in T4 and V-Band configurations, with multiple A/R values for precise matching with the engine

Suitable for 2.0 L – 4.0 L engines in single turbo configuration, or as a twin solution on large V-engines

Advantages:

Excellent response-to-flow ratio – faster spool than most turbos of the same power

Ideal solution for projects requiring 600+ HP with street usability

Modern integrated design reduces complications and the number of external components

High thermal durability for prolonged use at elevated boost
