.58MM For B1 Frame Turbine Housing By BorgWarner

The EFR (Engineered For Racing) turbochargers from BorgWarner offer an unprecedented combination of advanced technologies. Low-weight Gamma-Ti turbine wheels and shaft assemblies for quick boost response Patent-pending dual ceramic ball bearing cartridges for more thrust capacity, durability and turbine efficiency at low expansion ratios Stainless steel turbine housing for increased efficiency, improved durability and corrosion resistance Range of units supporting 225 to 1,000 horsepower per turbocharger.

EFR turbine wheels are made from titanium aluminide (or Gamma-Ti). Not quite ceramic and not quite metal, the material is very light-weight and demonstrates excellent strength at high temperatures. Because EFR turbine wheels weigh 50% less than typical turbine wheels, less energy is required to spin up the wheel, allowing the turbocharger to respond faster. BorgWarner EFR turbochargers also feature the newest ''super back'' and ''fullback'' turbine designs for high-boost, high-efficiency applications.
