Heat Management Testing and analysis (DEI heat wrap, Turbo Blanket, Reflective Tape)

[SRDFTITAN]

The next test conducted were the temps of the charge piping at the throttle body. This test just like the rest was conducted at idle, 60 mph roll and WOT.

Now the first thing that I noticed was the huge reduction in temperature compared to the reading that was taken at the turbo. I was seeing consistent readings of 73 degrees and holding pretty steady. This showed a reduction of 53 degrees when compared to the peak number at the turbo. This test was also effective as it showed how much heat soak effects the IAT's just on the other side of the throttle body from my probe. I was seeing IAT's as high as 131 degrees, even though just on the other side of the throttle body temps are a measly 73 degrees! WOW, I hate you heat soak lol!!









Conclusion: Post turbo blanket (idle) my temperatures behind the radiator, right next to my intercooler pipe that runs to my throttle body was 125 degrees. Now being that the charge piping temperatures are lower then the engine bay temps, I would wrap the charge piping from the intercooler to the throttle body with reflective heat tape to keep that air charge as cold and dense as possible!! WRAP AWAY!!

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!!

Ok sorry for the delay but I have the wide open throttle results. A slight increase in temperature was noted from the probe in the throttle body. However a slight decrease in IAT's were noted at the same time.





As long as everything goes according to plan, I would like to build a cold air intake box and intake pipe to run to my turbo. Right now my turbo is sucking in all the hot air that's coming from the radiator. After doing this a drop in charge piping and IAT's are expected. Stay tuned.

Have a few updates. I was able to build my Cold Air Intake box for my turbo this past weekend. Came out pretty nice. I made a template out of card board and then went back and transferred the template to some sheet metal that I had. All I have to do now is purchase a 3" hole saw and weld some tabs for mounting. I'm also going to fab some 3" piping from the intake box to my turbo. This should lower both my charge piping temperatures and intake air temperatures for sure! The intake box and pipe will be wrapped in the reflect a gold heat tape after more data is taken.

























Keep checking back for more updates.

Got the cold air intake box done today, forgot to take a picture after I ran to autozone and grabbed another coupler, but its on there. Not really sure if my mind is playing tricks on me but it does feel like the car pulls a little different. I'm pulling fresh air from the frame rail right now, but I'm eventually going to run a pipe to the existing fog light housing for even colder air. On to the pics (oh yeah I ran out of the gold heat tape) and don't laugh at my crappy welding. Will have some data very soon to document any changes in my IAT's.
