HMW 80MM SC14 Pulley
This HMW 80MM pulley for the SC14 will push between 6 – 8 PSI for the 6 cylinders & 15-20PSI on the 4 cylinders. Made as an High boost pulley for the V2 & V4 SC14 setups. Complete bolt on upgrade to an SC14 supercharger.
- Recommended to use this only after your installation and setup has been completed and you ensured there are no boost leaks, are happy with how the car runs, overall smoothness of the engine & a proper tune. Consider this the final touch.
This machined purpose build HMW 80mm pulley is meant to get more boost out of your SC14, its a fixed pulley and good for achieving the max recommended safe boost for an stock engine and most of what the SC14 can support while staying efficient and safe. This is a fixed pulley so you wont be able to use the clutch, it will also require a smaller belt.
Good for built 4 cylinder BMW engines to extract maximum power, we however don’t recommend using this on a stock M44/M42 or any other stock un-built BMW 4 cylinder engine as the boost will be very high 15 – 20PSI.
Fits all SC14 Superchargers, Both Cross face and non Cross face.
Dependent on Motor & Intercooler used.
Machined Aluminum, Silver, Laser Engraved. 4x M6 Threaded holes to bolt on the SC14 cross face.
