Re: Thermal Coatings

[PDQSHIP@aol.com]

Had an interesting set of posts from a guy .VR4@(?).... He had done the
thermal coatings, and was indicating that in the dark the turbo glows red hot
when he coated the manifold.....   Ouch, that was a scary thought to me.....
 These turbo cars could prolly use the coatings (let me know if you want the
details, it wasn't jet hot tho), but that heat has to go somewhere, my
thinkin is that if you put it at the turbo, and it sits in a glow state with
no "active" oil pumping, you are going to have a big coking bearing
prollum.....  If you skip the manifold and do the turbo, the manifold will
glow and will by property go back to the "trapped heat" turbo on shutdown (no
flow), if you skip the manifold and the turbo and do the downpipe, then the
turbo and manifold will glow......  Catch 22, and the audis are NOT known for
their cool engine bays (heck I preheat the garage with my car in the
vinter)....  Me thinks you should look at the exhaust from a flow perspective
(EH the man or Incr pipe dia, reduce restriction) instead of a thermal
perspective, trapping heat is a dangerous endeavor for the marginal
gains.......  hmmm how bout cooling the motor as a whole with another oil
coooler.....  Those oil jets onto the bottom of the pistons gives thought
........
