A great place to get things coated to reduce heat/friction/etc. is Swain Tech. Do a search on the internet for the site.

Not a coating, but there is the Outlaw Engineering Thermoblock spacer kit for only $115.00sr20andafalcon said:if im not mistaking i have seen people talking about it on here im gonna try some on my race car
I give it two thumbs up!NX2KTPR said:Not a coating, but there is the Outlaw Engineering Thermoblock spacer kit for only $115.00

Supposedly good for 9HP and 7Lbs of torque...
Check out outlaw's website they have temp. data from before and after. Or even better give them a call... I talked to one of the doods from there for ~45mins, very nice and informed guy.for 115 bucks id like to see some proof.
Even if your personal results are 1/2 what the company claims, that is still a great hp/$ ratio.mr_cool_guy said:for 115 bucks id like to see some proof.
They have dyno numbers along with many testimonials that their product does exactly as they say it does. It was spoken about for months as they developed the SR20 kit for us. Search!mr_cool_guy said:for 115 bucks id like to see some proof.
If you have a spacer between the head and intake manifold and that you bypassed the coolant lines, the coating for sure will not be trapping heat in as it is much hotter in the engine compartment then below the manifold surface. The heat convection due to the cold air charge within will maintain the manifold metal at a cold temperature. The radiating heat from the engine and the heat conduction due to the heated, under-hood air will be a constant heat source for the intake manifold.gottabfast said:does the IM get that hot that more than the spacer is needed? Other than putting more air over it, I don't know another way to cool it. I'd be worried or want to see some tests/data that show that a coating isn't trapping heat in.
I had it backward then...I was thinking in terms of a coating that would dissipate heat quicker instead of not conduct it in the first place. I was looking at heat by conduction from the head as inevitable. There are coatings that help dissipate heat quicker. I believe Swain makes it actually.

Sr20falcon, if you are going to get a spacer, then you can coat both the upper and lower manifold. If you are not, you should only coat the upper manifold, and you must bypass the coolant lines.
What I use to coat, was white epoxy paint, white poly-urethane paint, and and acrylic clear coat for outer layer. Epoxy, poly-urethane and acrylic all have very low heat conductivity and the color white is the most reflective against heat radiation. These paints however will melt under high temperatures. Never use black or metal(gold, silver) color paints. Black acts as a black-body radiator and will absorb radiation quicker than anything, but would be a good choice for painting radiator or intercooler though. Metal color paints contains many metal flakes and particles to give it that color hence these paints will have very high heat conductivity. Also don't get the high temperature engine paints eventhough they are silicone/ceramic based. The properties of these paint is high heat permeability which enables heat to transfer pass them with little hindrance, hence they can withstand extreme temperatures.
