Real-world performance gains
PWG N55 models: typical gains are around 50 hp peak with 70 to 80 hp at the top end depending on supporting modifications. Expect a responsive drive, stronger midrange punch and sustained power to redline.
EWG N55 models: top-end gains are up to 10 hp over the stock EWG turbo. Because the factory EWG compressor is already larger, we recommend considering the Pure Turbos BMW N55 Stage 2 Turbo if you want a bigger jump in performance.
See the dyno graphs in the product gallery for reference.
