The fans are both running in the correct direction. I am using a restrictor in place of the t-stat. The problem is the same as when I had the t-stat in. There is no kink in the hose. There is no screen in front of the raditor.
408 windsor from SA. I Just double checked the timing @ 28 total.

Am I missing something regarding "burping" the cooling system? There is an expansion tank right on top to bleed out the air. There is no thermostat for the air to get trapped at.
I believe the problem is air flow related. It does not change with engine RPM. Only with speed.
