Ceramic coating does it help
 

I have a FD with a garret T04S and all the mods. I sent off my intercooler and radiator to get made into a v-mount. I am currently getting some parts powder coated and cleaning up the engine bay. I am looking at getting the LIM, UIM, manifold, down pipe, and hot side all ceramic coated. I am wondering if it helps a lot? I know that it will keep the motor bay cooler but will it increase HP?

Anyone........I might have this in the wrong section. Like i said i know it will cool the engine bay a ton. Will/does it spool the turbo quicker, add hp? what does ceramic coating accoplish besides cooling the engine bay or is that all that it does. I already have the parts at the coater. thanks for the help

No one that i know of has managed to show gains over standard error. The heat is moving through the manifold/turbo fast enough that the relatively small quantity that is retained by the ceramic (instead of lost as waste heat) is negligible -but what is negligible on the inside can make a big difference on the outside.

tl;dr- no, i've never seen conclusive proof that coatings make power. however, benefits do exist.

+1, I've only seen correlation between people running reliable good power that happen to have great heat insulation (like busted7's 500whp DD) I've never actually seen someone do a test to prove that it makes a big difference. I would think a turbo blanket would be somewhat more effective in retaining heat than a thin coating of anything.

Really what im doing is cleaning up the engine bay. But i wanted to know if it helped at all. Thanks for the input. Just trying to justify spending $550 in the ceramic and powder coating. Should clean it up and make it look a lot better. Plus with the intake manifold off I decided to run 2000cc injectors and running E85. I hope it makes over 500 hp this time.

its alright im still trying to justify spending 19.5k on a FD with a broken trans....

I spent 15.5K on a FD with a bad turbo. Blew the motor on the ride home.....still trying to get over that.

That sucks x2 guys. I think that's why I've stuck with the FC, I couldn't bear to spend that much on something that I know will very likely break!

Coating the rotors would have helped to reduce heat transfer into them and the oil. But it is too late for you to do that.

Which coatings can handle that? I don't remember where but i saw some nasty "after" (read: rebuild) pics of ceramic coated rotors that were chipping.

I know that JetHot coating goes up to 3,600 degrees. I dont know of another coating that goes higher. But yes i heard that coating the rotors can cause flaking. That is why i didnt do it. Shop told me not to.

well cooler intake air temps will increase hp, and ceramic coatings will help it from heat soaking would it not.

the way i look at it is $550+ of extra reliability, power increase be damned.

after all you've already spent, an extra $550+ is a drop in the bucket and there is no arguing that temperature control links directly to engine reliability.

Well i am installing the parts now. Installing a V-mount and will be running E85. So with all these mods the car will run cooler. Shorter pipe for the intercooler will help with turbo lag. But if anything $550 dressed the engine bay up. Even though all of it is black.
