Looking at getting intake pipes and was wondering if anyone thinks there is any benefit if I was to get them painted with a ceramic powder coating.

Also wondering about thoughts of the Aluminum heat soaking faster than the stock tubing. Granted it will heat soak faster but it will "cool soak" faster as well with air flowing through the intake.

Does it matter??

 

I really dont think powdercoating it will help at all...unless you just want it to look nice...intercooler should take care of the heat.

 

Powder coating is cosmetic.

 

Hey Brent,

here is a link from awhile back where Batman mentions the ceramic coating but to the UIM and such and noticed a 5 degree drop on the PFC....

I have a couple of these links booked marked.

About the intake piping...I think there has been alot of subjective opinions...but no objective data...

it seems like if you are going to do it....you need the black as it has the best thermal properties....it just messes with the bling factor....

oh and when you mentioned "powder coating" i assume you ment the ceramic coating...correct?

 

yep cermakrome... Leave it to a Dr. to be as obsessive as me.

I just HATE the thought of having to polish my apexi intake... But ever since I saw that one for sale that looked awesome I knew I'd want to eventually have mine like it..

From what I heard Black Satin is the best Cermakrome is second best - both made by Techline coatings. The thing is that Batman probably only noticed the drops from the turbo housings Don't see how holding in the heat on the UIM/LIM would help lower water temps...

Also I agree that coatings/wraps are a good idea on the exhaust side + turbo, but it seems like a PITA to do unless you are unfortunate enough to need new turbos - which I may be in need of - who knows...

 

It can have thermal and aesthetic benefits.

 

well Brent,

let me know what you are going to do...I figure it is the same principle that people use in justifying jethot coating for the downpipe...hey why not other pipes???

I actually have one of the older post where they talk about ceramic coating the rotors...with the engine out...I was seriously debating trying it...I think someone said that they had more horsepower, higher compression, and lower water temps...

 

Ceramic coat the rotors?? I'd be scared that it would chip off and destory things (apex seals, housings, turbines, etc.) Not to mention increasing the compression ratio, thus increasing the possiblity of detonation.

 

paw,

that was discussed in the older threads...and apparently it doesn chip off...and also...I think the lemans mazda had ceramic coated rotors...dammit ur gonna make me pull that link out too!!

 

ok here is the link....just read the whole thing

and here is one from the late Mr. Wankel

I posed this question a while back. Seems to me with any part you just have to ask one question:

Is the air outside the part hotter than the air inside the part or vice versa?

Ceramic coatings are insulators, so just as it will seal heat IN to a downpipe, it will seal heat OUT of an intake pipe, right?

 

if you coat the uim/lim inside and out the intake air (and IAT sensor) won't heatsoak and air temps will drop. doubt it would help water temps much but the two do have at least a small effect on each other. at least thats how i understand it.
