Might be a good idea. I have a Meziere EWP (the HD version) but I've always had the bypass open, I've never tried blocking it. Seems to flow great when I look with the radiator cap off.

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
