Next up was the 60 mph test of the charge piping at the throttle body. During this test charge piping temps dropped even more with a consistent temperature of 64 degrees. Thats a 9 degree reduction when compared to the idle temp. There was also a 41 degree drop in IAT's.





Conclusion: Now remember that my under hood temps at 60 mph (post wrap) were 56 degrees. Now your probably thinking; he just told us in the last post to wrap the intercooler piping between the intercooler and throttle body, but the temperature of the charge piping is higher then the temperature of the engine bay at 60 mph!?

Here is my theory: If we can radiate as much heat as possible with reflective heat tape during idle, this will make your starting charge piping temp lower then if un-wrapped. We saw the temperature drop from 73 degrees at idle to 64 degrees at 60 mph un-wrapped. I feel that if the piping is wrapped it will reduce the charge piping temps even more, making the under hood temperature of 56 degrees irrelevant. Just my theory, don't kill me, will be wrapping the piping from the intercooler to the throttle body shortly!!
