hey i was thinking about powder coating all of my suction pipes, intake charge pipe and upper plenum on my greddy tt but i'm scared it will raise my IATs...........i know that national speed powdercoats there turbo kits and they said they didn't see any changes to the IATs but their kits are ST and i know that tt put off alot more heat...............so what do you guys think?

Nothing you need to worry about really, technically you will have worse heat transfer through the pipes themselves, but your intercooler is doing about 99% of the cooling in our situations......

fyi, all my pipes are powder coated black, except hot pipes which are coated for heat.

 

thom. does your sig say "built stock block" . lol. what in the world does that mean.

 

thanks..........when you say hot pipes are you talking about just the pipes coming off the compressor housing and going to the intercooler?

 

I think he means the turbine side of things are coated to keep heat in and exhaust velocity up (manifold, turbine housing, downpipes, etc). I don't see how powdercoating the intake pipes can in anyway hurt IATs since engine bay temps are higher than IATs. In fact, I think thermally insulating the intake pipes in regions near the engine is a good way to keep the heat OUT of the pipe.

 

All my pipes are powder coated, go for it!

pics? i'm interested in how it looks.

 

yeah the only thing i was worried about was that powdercoat is a thick layer of plastic and it doesn't breathe like paint but you guys are right the intercooler does 99% of the work.............i think i was just getting parnoid...........so what color do you guys think?..........the car is silver, wrinkled black?

 

I did a bit of powder on the intake side, just the plenum since the pipes that come with the APS TT kit are already very pretty. I recommend a ceramic coating for things on the exhaust side, you can do inside and outs on the pipes and manifolds (I chose outside only), but be careful on the turbo housings since it may void your warranty (which I just did by modifying them since they were POS turbos). Here is a few pics:

 

Very nice Cass. I wish I had ceramic coated pipes now. I might just do something with the plenum and charge pipe now that I see how well yours turned out. No matter how much you research and plan, there's always something else... ah well, next time .

 

- You speak the truth Raj. I just realized the other day that I should have planned to spray the engine bay DB when I swap motors cause the base blue in the bay is dull and beat. Maybe I can pull an all-nighter at Franks place and just buy myself a little sprayer and some DB paint and hook it up to the shop compressor. I've got about a week to noodle it through.

 

Dave - If you want to see just what kind of an impact powder coat can have on the appearance when you pop the hood, check out my build thread here:

Just be prepared to spend some cash and then wait a while for stuff to get done.....pretty much like everything else in F/I .

yup

I'm still on stock sleeves

 

I agree.

I am seriously considering ceramic coating the inside of my intake tubes between the intercooler and the intake plenum to provide thermal insulation. I also may ceramic coat the inside of my Cosworth intake plenum, intake runners and the spacer between the plenum and the runners after the match porting on these is finished. It may only help a little bit, but alot of little things add up. I used Fusion here in So. Fla. to ceramic coat my exhaust manifolds, turbo housings, downpipes and exhaust system, and they turned everything around right away at a very reasonable price. They have been doing ceramic coating on performance parts for something like 20 years or so, and seem very knowledgeable.

I am sending my heads and valves to PolyDyne (Houston, TX) to ceramic coat my combustion chambers, valves, intake ports and exhaust ports. They also have alot of experience with racing engines and are reasonably priced. Fuzion may have the knowledge, skill and ability to do the heads, but I figured I would stick with PolyDyne for the heads based on recommendations to use them both from Wiseco and Kyle at Import Parts Pro. Evidently, Kyle has used PolyDyne for many years to apply various coatings to engine internals, and has never had a problem with the coatings.

 

thanks cass..............everything looks really good...i love that color blue..........i'm not to worried about the cash or time part cause i use to powdercoat for a living for hatteras yachts and i have all the stuff to do it at my house i just gotta buy the powdercoat.................i'm thinking maybe metallic blue

 

I've read mixed opinion about ceramic coatings within the combustion chamber. Heat needs to be released somehow and whatever doesn't get coated bears the brunt of that energy. That leaves less surface area for dissipation. It'd be nice if most of the heat went out with the exhaust gases, but I'm dubious. That was one thing I considered in advance and decided against. I'm not sure about it helping or hindering...

 

In my useless opinion I would think that doing the coatings in the combustion chamber (like swaintech coating) will help with a more consistent, and even burn in the chanber, so fewer "hot spots".....but its just a guess.

I concur.

 

Fusion did all of my coating as well, I could not be happier.

 

Your mom couldnt be happier either as of lately
