Re: Building the supercharger to the engine (75 3.0V6)

almost ready to get MOT. Did some testing miles on the road. Looks all good. Post you the last updates: smaller water pump pulley for cooler idle temps at hot weather. Full load never is a problem. I see around 82 degrees celcius then. https://myalbum.com/photo/kWc9GV7esKwN/540.jpg Reduced unusefull...

Re: Building the supercharger to the engine (75 3.0V6)

No sequential injection for me...

Re: Building the supercharger to the engine (75 3.0V6)

OEM prob setup with BMW middle donut. Never had an issue with it while drifting and racing it.
Hope this isn't going to be an issue with the new low comp pistons..
