You don't. By the time the engine was running and fitted in a car the factory water pumps were gone and an auxiliary water pump was mounted and driven off the end of the supercharger.
Off topic, but does anyone have pictures of the drive ***embly for the front mount blower? Basically, I'd love to see what's hiding inside that aluminum box.
That is the million dollar question! I think it's a chain drive setup, but have never seen it or pics of it. 3blap.
