water level is full, no air in the system. Never have the buzzer go off. Neck is always full when I pop the cap off cold.

*No slipping on start up or squealing.

*I have a larger WP pulley I'm about to install.

*I have a fan switch wired to one of the relays that was on the car form the previous owner. I'm guessing it keep the fans on medium or low...not sure which one. If I flip the A/C switch with the car off but ignition on, fans speed up.

*Undercover is cracked towards the back in places, but the front half from the oil pan foward is pretty sealed up. I do have foam around the radiator gaps.

*I have the AST relocated to the side of the engine bay...its bolted where my battery used to be...battery is relocated.

*I have Large SMIC with Aluminum Ducting. I'm thinking either this is causing heatsoak, or my fans just aren't running fast enough with my fan switch to cool down the car. I"m too afraid to run it up to 225 to let the stock fan sensor kick in.

*If I turn the heat on, temps always drop DRAMATICALLY (which is why this is puzzling).

*Also, I CANNOT, CANNOT, run the a/c in this heat...even on the interstate, at 70mph, the car will creep really fast in temps.

*I also have dual oil cooler....my temp sensor is the Defi D-gauge and I believe the sensor is tapped at the water pump.

*When I first purchased car, before the I/C/Duct/Airpump removal, the car never creeped above 185 with fan switch on.

*I've checked the thermostat, replaced it twice. I've changed the coolant probably 4 times in the past 3 years. 80% water/20% Coolant


Please help me figure this out....I just want to know whats causing the creeping temps before I purchase anything...whether it be the aluminum intercooler duct blocking airflow from the fans, fans running too slow, or undercover being cracked. In the winter car stays pegged at 180F
