oh just supercharge it lol
On an inline six BMW engine? Naw. I like my nice perfectly flat torque curve and non-strange peaky performance and metronome-like accelerator. With a light enough flywheel, I could play a song with my gas pedal. Can't do that with a turbo or a supercharger. Although I do like a supercharger better than a turbo for autocrossing, I'd much rather have a built motor. I'm not looking for more than 320ish HP. I can get that with a built S38 easy with a mountain of torque.
