Find a shroud if possible.
Is your timing correct?
Is your timing correct?
To do this use a laser temp gun. The only accurate way.Check the radiator temps from top to bottom just because it is new does not guaranty it is flowing correctly. Should get cooler at the bottom.
180 Stant Superstat. Green coolant. Mancini Billet housing so no leaks.
Are you sure pump is turning the correct way?!
Trying to Invision this being a centrifugal vane pump running back wards should throw water towards the lower hose instead of the upper outlets. As suction would be in the direction of rotation.If the pump was turning backwards, it would still flow in the proper direction, but at a reduced level. Regarding flow, more flow=more cooling. That's why the thermostat opens as the engine gets hotter. There's a smaller temperature change in the engine and the radiator, but the amount of BTU's dissipated is increased.
