I have just been looking at the data logging from my 4agze on my buggy from oran pk on the weekend and there is no chance that the intercooler is getting hot from the exhaust or the radiator because its all out in the open and there is plenty of air flow around it, but with the top mounted intercooler my intake temp was around 120 degrees just from the heat radiated up from the motor. i have been told to move it and it would drop to about 30 degrees which means a big jump in horse power.
