![]() Talked with Jack Wilson at Stewart he told me my problem is my Crank pulley is smaller then my water pump so I am under driving the pump, he said there is no benefit in this. Told me you need 10-35% ratio difference between the water pump and crank to be efficient, if I swap pullies it should solve all my problems. You need to under drive the pump when you see a constant 7000rpm to keep it from cavitating, they do this on the Nascar pumps they provide.
I have no idea where my stock pullies are, guess I need to see if I can find a set of stock pullies.
