BorgWarner EFR turbochargers were designed and built with just one goal in mind: to dominate the road, race track and the 1/4 mile. BorgWarner EFR turbochargers feature the latest high-tech features, unbeatable performance and top quality.
EFR Turbos are available in 8 different sizes and 7 different turbine housings, the power ranges range from 250-1000HP per loader.
The combination of highly efficient compressor wheel, gamma titanium aluminide turbine wheel, combined with ceramic ball bearing technology raises the bar for racing turbochargers to the very top and represents the highest level of racing turbocharger technology. We also use the turbocharger in our race cars and also in converted private cars of our employees. So we could best collect experiences that we can now pass on to you. In addition, we were able to extensively test them in racing as well as on the road to ensure that the product actually meets our high standards.
