AC Supercharger

Our First Rotrex Centrifugal Supercharger based kit is now on it’s way! We introduce you to the B.R.O.S.K. – 1. Built specifically for the racers and car enthusiasts who like to take it to the Race Track!

Short for BMW Rotrex Supercharger Kit, B.R.O.S.K – 1 was developed in house by Mas Schandorph of Mas Motorsport Wiring (M.M.W.) in in Roskilde, Denmark. The B.R.O.S.K. – 1 supports the Rotrex C30 as well as the Rotrex C38 family of superchargers.

The projects development began in 2022 and was completed this year. To demonstrate its track ability, a total of 2 BMW E46 cars (Blue 325i and Yellow 330i) were built for this kit and then taken to the track!

After being track tested over a hundred times, this kit is now approved for production this fall.  The B.R.O.S.K. – 1 is our highest power output centrifugal supercharger option so far M5x and S5x engines. With the smallest foot print yet, the robust design of the bracket system mounts in place of the AC unit, and brings forth the high efficiency and reliability found in the Rotrex brand of Superchargers.

Having a Supercharger on a BMW already is something special, but what’s more special here is unlike most centrifugal superchargers, the Rotrex line of Superchargers offer a low down linear power curve and raw torque figures, which comes close to the traditional Hyde Motor Works Roots and Twinscrew supercharger setups.

Below we showcase what very low boost figures can achieve with just the Rotrex C30 supercharger. Keep in mind, the power is measured at the wheels, which means the final engine HP figure is about 20% higher.

B.R.O.S.K. – 1. has an expected release in Early Winter of 2023 with discounted Pre Orders available from August directly through Hyde Motor Works.
