I have my 34 row from Fast Intentions directly behind the IC and in front of the radiator. I live in Guam where it's 80-90*F tropical weather year round. There's a lot of stop and go traffic and I daily my car with spirited driving every now and then and hit the track every month....Oil and Coolant Temps have been good...Coolant temps get as high as 199*F and oil temps don't pass 200*F when I push the car hard or track it.
