Jet Hot coating
 

We added jet hot coating to my headers and mid section this winter because the ls7 was generating a lot of heat on the track. We felt that the oil lines were too close to the headers to be comfortable with continuing with heat wrap and the inside tunnel was extremely hot so we sent everything out for extreme coating.

This weekend at NJMP I did some temp checks against another header on a c5 which has a H/C installed.

After we got in the garages I checked my temps and then the uncoated headers temp. I found my temps to be a bit over 200 degrees cooler (180 vs 380).

I also noticed that my temps would drop faster than the uncoated headers while we sat there. This was good news but threw off my initial testing because from the end of the session to the garage I was dropping faster so I don't know what my high temp was compared to the high temp of the uncoated.

Keeping that in mind though I believe that the jet coated headers are staying cooler and cooling down quicker than the uncoated which is all good news.

Any of the better coatings will only help for sure :thumbs:
My 4l60e loves coated headers/midsection & to the exhaust muffs/tips.
