Even if it is apperance I think it is benificail because of the rust factor and it helps every thing stay a little cooler in the engine compartment.

 

[QUOTE=Timmay2]It does reduce surface temperatures of the parts coated. This is proven in many cases with infrared thermometers. A reduction in the surface temperature only means one thing, the heat is kept inside.

more heat = faster spoolup.

Would that create higher egt's too?

 

that website i put on here was wrong its http://cradin.com/ if anyone is interested.

 

I found these guys: http://clmcenterprises.srv08.yourhost.com/uper_hi.htm

The guy said 1 pt will be enough for the exhaust manifold and exhaust housing of the turbo. MUCH cheaper than sending it in.

 

I have a high temp powdercoat on my manifold. Looks real nice as far as I'm concerned thats all it does but I dont have dyno results or anything. I'd be careful with header wrap. Moisture likes to work its way inside and speed up rust and deterioration like crazy.

 

Looks is about all the performance we could verify with coated manifolds..... I do like them for this reason though!

It definitely looks better than the rust that will form. That's worth it right there!
