While on a NA engine, this would have a negligible effect, on turbo'ed engines, this keeps our spool up.Header surface temperatures were a whole nother story, however. We checked header-tube surface temperatures both at idle andin an attempt to simulate part-throttle, sustained cruise conditionsat 3,200 rpm with a light, 60 lb-ft load applied to the dynos water-brake. In both cases, the coated headers cut the painted sets surface temperatures by over 50 percent. In a real car, this would significantly reduce both coolant and underhood temperatures. In the dyno-cell, we could actually touch the coated headers with our bare hands within 5-7 minutes after engine shut-down!

Good choice putting $4,000 rims on your 1990 Honda Civic. That's like Betty White going out and getting her tits done.

Re: Jet Hot Coating
Hmm...so now I have to coat the inside of my downpipe, too? That will be a real PITA. I think I will just take my chances with the outer portion of my DP coated in Black Satin.
Thanks for the article. Very good stuff to know. Maybe I will keep my EQL headers since they are ceramic coated inside and out

Re: Jet Hot Coating
Only need to coat the inside of a mild steel pipe. If you have SS, it has higher corrosion and thermal fatigue resistance than the cheap metal. So pay for the good stuff once, or pay over and over for the cheap ones.sirwilliam wrote:Hmm...so now I have to coat the inside of my downpipe, too? That will be a real PITA.

Jet Hot is OK, but if you are going for the absolute best, then you have to give it to Swain Tech Coatings. Different league than Jet Hot, they will treat piston skirts and bearings with high wear, low friction applications too. Bad ass
