I was pulling my hair out, until someone noticed I had a hi flow waterpump. Swapped it out for a stock replacement and problem solved. This was on a supercharged car as well.
I fear you may be exactly on the money my friend!!! I think if I had a regalar old belt driven water pump my problems would be solved. I do have a 33gpm Mezierre that I used to run and the motor seemed like maybe it did a bit better, the guy at Mezierre said my water pump was too small and I then bought a 55 gpm pump. The larger pump will empty out the coolant system in a flash!!!
