Reply to "Increasing the cooling system pressure?"

I have over 520 hp and still use the stock water pump. Compression is 10.5:1.

Even with my old stock rad I could sit in traffic all day and barely break 200 degrees. With my new Fluidyne, even after a high speed run on the highway I can sit idling in the 90 degree sunshine in my driveway and barely get to 200 degrees.

On the highway I have to turn my fans off or I would drop to 160 degrees. And that's on a hot day!

I think it has more to do with good new cooling tubes, hoses and a proper thermostat - along with good engine circulation, ventilation and oiling systems.
