Just finished a supercharger conversion on an m535i for a customer of ours, not supercharged one of these before but done sevaral other 6cylinder bmw engines, stuck to 6psi using a rotrex charger, all the boost pipes etc were all custom made...
anyway pics:
few pics:
Used a Rotrex supercharger, Gotech MFI Pro X ecu and custom loom.
made 270bhp once completed just need some better brakes now!
I'm really interested in the pulley set-up. I've got mine about 50% finished but haven't given any real thought to the pulley situation yet. I really wished these cars used a single serpentine belt.
We modified the bottom pulley and added a multi rib pulley to it, then ran a multi rib belt off that to drive the charger, i will get some better pics of it later.
we also machined the bottom pulley on the front to rub a 60-2 trigger wheel using the standard sensor.
Awesome, so this is on a high compression euro motor I'm imagining? I just put a high comp in my car, and although the increase in power is really nice, i want boost. Was wondering how it would go with high compression and boost.....
That is a really nice powerband! As expected it looks like a more powerful NA car. It looks like a really clean install. I'd love to see some more pictures of the mounting bracketry and tensioner assembly if you've got them.
