Jet Hot Coatings

[Cody 82 ZXT]

Anyone ever use Jet Hot Coating on their turbo cars? I have been thinking about doing this for years but, I'm curious about the cost to benifit ratio.

 

Thanks,

Not sure if you can really quantify it. Just remember that heat is a turbo's worst enemy and high underhood temps will kill any hybridZ. For a turbo car I recommend the exhaust manifold, underside of the manifold heat shield, the turbine housing and the downpipe. That'$ going to add up. On the other hand, consider spending a lot of dough for a good I/C only the have the I/C to TB pipe getting very hot and the bottom of the intake almost glowing . Kind of defeats the purpose. Nissan put that ugly fan by the fuel rail for a purpose. It gets hot under the hood! Worse case you end up pouring unnecessary $$$ into making the cooling system more efficient.

One interesting thing about those coatings: radiant heat does go down.

 

I had my headers and most of my exhaust system stainless/ceramic coated by Baxter Custom Engineering (thanks for the tip, Scottie!) - now under business restructuring and not doing coatings at this time. The stuff is nice.

 

But here's one observation. One of the reasons these coating are nice is the low-emissivity of the material. Low emissivity means that even though the material and pipe are still very hot, it radiates less heat than if uncoated. But that can be dangerous. I sit here with many scars and burns on my hands from accidently touching the hot pipes working on the car lately. The problem is we have been trained that if it doesn't radiate heat we can get close to and maybe accidently bump into the exhaust system. Not so with this coating. It can be very hot to the touch, but the heat it radiates is very low.

 

The other great things about it are that it looks good and prevents corrosion wonderfully.

 

Since it's a low emissivity coating, you don't want it on anything that you want to STAY cool. As Scottie points out, doing the total intake would be a mistake, as it would very inefficiently radiate the heat that's conducted into it by the engine, etc. When it's polished, it reflects heat well.

My NA headers are Jet-Hot coated. The main reason I did this was to save the headers from rust-out, being it took 2 weeks of a lot of work to make them, and I don't want them rusting away to nothing. But the added benefit of the rapid cool-down is quite noticable. Ten minutes after shut-down, I can grab and hold the warm header tube. The tubes aways look good and stay clean too. OH BTW, Pete, Thanks for the long awaited signature picture of you Z. Looks every bit as good as expected.

Terry, for some reason (hmm...maybe it's that low-e coating ), my pipes, even the exhaust that's coated to before the mufflers, stay hot for at least ten minutes after shut down. And I coated my exhaust for the same reason you coated your headers - I hand built it with mandrel tubes, probably 80 or more hours of labor, and I figured I'd preserve them a bit, as well as try to cut down on heat in the car.

 

Oh, that's one of the 3 pics I took just before the drive. It shows the color better, and someone was asking for one that had a better rendition of the color. I need to get the other mirror on before I do another exterior photo shoot...

Jet-Hot claims 30-40 degree temp drops if you have them coat the inside and outside of your headers. We all know all to well how the underhood temps of the Hybridz can cause some problems. Heatsoak on the starter being a big one and not to mention the loss of power..

Thats the best looking 80 something Z I've ever seen. I usually don't like anything between 74 and 1990, but yours looks awesome with that bodykit, it's very clean.
