I'm going to be getting my EVO headers and Aluminum intake pipes ceramic coated. I just got off the phone with the guy and he's saying there wouldn't be any trouble coating the insides also, despite what I've read many times on this board. He says he has the shiny, high aluminum coating, similiar to Jet Hot and a matte black finish. He says the matte black stuff would provide better insulation, but is somewhat less durable.

[edit] do you need the 2000'F stuff in order to make this process worth while??

Any input?

You know.. Kevin is the man when it comes to all things coating. He knows that stuff inside and out (no pun intended). A set of headers I used to have was coated by him and they NEVER peeled and were cool enough to touch while running. PM him cos he could at least tell you wrong from right

 

Don't coat the insides

 

dont coat the insides..... Kevin is very good .

 

A lighter color should radiate less heat than black.

 

You want the heat to be contained in the exhaust and expelled out the back away from the engine, you don't want it to be radiated into the engine bay. Using the ehaust wrap in conjunction with heat coasting is the best way to contain heat and stop it heat soaking everything in the engine bay.

Aluminium has a low melting point of around 660 deg C (1300 deg F) so any coating based on aluminium will burn off at around this temp, thats why they have lower temp ratings (won't suddenly dissapear but begin to degrade). The black stuff is more likely carbon based or something like that at a guess thus able to withstand higher temps.

Also any intake piping that is around the turbos etc can benefit from heat coasting aswell. All a point of how far you really want to go, It won't suddenly give you untolds amounts of more power but more stable temps in the engine bay and intake.

 

Zippy,

Run .................. don't walk away from that guy. Alumimum coating of any kind will melt off in a turbo exhaust. Do not coat the inside of turbo's or turbo exhaust. As for the intake you don't want a ceramic coating, you want a heat dispersant. Take a look at HP Coatings www.hpcoatings.com or Swain www.swaintech.com

 

NO NO NO...Do Not coat the inside. Send them to me we are set up and dealers for Swaine. Yikes, no coating inside. Bad. No aluminized coating, bad...

 

Zippy,

The above two posts should convince you.

 

Ok, ok, ok... I have no intentions of coating the inside of anything. I guess I never made myself clear. Doooohhh!

Stephen - If you have a set of Kevin's ported OEM headers lying around, I would like your opinion on how they would perform (swain coated) as opposed to the after market ones I'm currently using, in conjunction with the 700 kit. Or should I send you the after market headers for ceramic coating. I believe you had a set of ported OEM's from Msindi kicking around some time back. If I have to send you headers, mabey i should send you the turbos also and get the turbines done too. Please email me with suggestion.

As far as the aluminum intake tubes are concerned, what should I do there (if anything).

 

I was more talking about the intake of the turbo and piping out of it on the AIR side of the turbo, the rest of the intake track shouldn't be coated (this should be done in the silver coats as it better at reflecting the heat while the black holds it) I should of been a bit more clearer. Note this is from my experience so other people may have other veiws on the matter

 

Polish them unless they are really getting hot (and you have a high intake air temp) I wouldn't worry about spending any money on coasting them.

 

Zippy,
Stephen and I decided to have my headers, turbine housings, and EVO aluminum intake manifold coated with Swain's white lightning coating. The coating looks great and should be very effective in keeping the heat inside the exhaust and out of the intake plumbing.

KraSE,

To each there own. As you go up the power ladder each additional hp becomes progressively more expensive. The extra ponies are worth it to some and not to others.

It is a fact for each ten degrees (to a point) you drop the intake air temperature ............. you will realize a 1% increase in power. It is realistic to lower your temperatures by 30 degrees. If you started with 700 hp you would realize an additional 21 ponies.

Aluminum is a big heat sink. It's like adding a heater instead of an intercooler to your system. It is no wonder carbon fiber intakes outperform the metal intakes. Aluminum does however have it's place (where cf is unavailable or too expensive). If you have to use aluminum then applying a thermal heat barrier coating will make the aluminum product better. For your information, there is also an internal coating (for piping prior to the turbo's) that will increase the flow rate of your system.
