Before I relocated my TFI I used a digital laser IR thermometer to measure the distributor mounted TFI and the fender apron after a drive. The fender apron was holding around 90-100*F and the TFI module/distributor were in the 160-180*F range. I felt this was a significant temperature drop and could only help reliability. If you mounted it on the opposite side of the apron I'm sure you would see another drop in temperature, but you would loose servicability. I have seen people mount it in front of the core support, taking advantage of the ambient temperature and ample airflow. McCully mentioned this and said their concern was water intrusion from rain or car washes. They may have a point there...so I went with high and dry at the top of the apron.
I think the important point is to get the TFI module moved to a cooler location with whichever kit and vendor you choose. I wish I had done mine years ago.
