Scott 89- Pull the radiator shroud off and clean out between the rad. and condensor, you should see a big difference. Pulling the main fan off and waterblasting the fins of the radiator towards the front of the car will also help. Keep spraying, there's tons of tiny debris that really get stuck in those fins.

Remember, too, that part of the ability of the coolant to absorb or reject heat is dependent on the difference in temps. If the coolant gets cooler by traveling more slowly through the radiator, then it will be able to absorb more heat from the engine, first because it was cooler going in and second because it was in there longer.
If the time in the radiator is increased, so will the time in the engine.
RACE ON!!!

Ah, this'll remind me to not make such a post hastily, and when I'm overtired.
Thanks for the correction, CFI-EFI
Be well,
