B.R.O.S.K. 1 Supercharger Kit

B.R.O.S.K. 1  SUPERCHARGER KIT

The BMW Rotrex Supercharger Kit 1, in short B.R.O.S.K. 1 was developed in Denmark by Mas Schandorph of Mas Motorsport Wiring in 2022. Capable of remarkable power gains up to 150% over the stock engine and nearing performance output only possible from our flagship M1 REV 2. This peak performance is due to the B.R.O.S.K. 1 being based around the incredibly efficient Rotrex Superchargers, the B.R.O.S.K. 1 Supercharger Kit is built for the BMW M50, M52, M54, S50, S52, S54 engines.
