Hey all,

Wondering if any of you guys used this on turbine housings and downpipes.  If so, does anyone know how much under hood temps reduced?

I'm thinking about getting my downpipe done, then possibly the turbine housing and wondering if it's worth it for keeping things from frying

I've got my turbo's hotside coated and I can say that its helped cut down on radiant heat but I think what it does better is help with spool.

EDIT:  A picture for you. You can see both the coated manifold and hotside.

Cool thanks.  Did it help much with the heat or marginally?  I'm more concerned with heat then the spool :)

I think if you aren't looking for every little bit of help you should instead spend money on a turbo blanket. While the coating does help its not a massive difference. Of course if you did both a coating and a blanket then you'd see a significant change in under hood temps.

Looks like I'll do both!  I won't bother with the turbine housing until I get it milled or find a cheap 16g

Are you talking about the same cerakote that is used on firearms? Or do they offer a heavier, more durable coating that you are considering? Speedy, exactly what is on your mani and hotside?

This is the stuff you want. I've had SwainTech coat a few things for me with great results.

I don't think the company who makes the gun coating makes the thermal coating by roughly the same name but I could be mistaken. I will say though that I know there is a thermal coating with that name. As for what brand coating is on my hotside and manifold, I'm not sure. Its whatever RonnieJ and jdlAutoDesigns have deemed good as they did both of them. Whatever it is its durable as hell, hasn't discolored, or flaked off in any way.

Fair point but I also believe it's pretty common knowledge that ceramic coating does less for cutting down radiant heat than a blanket does. That was my main point 😎

The blankets do a very good job to regulate underhood heat. But the ceramics keep heat in the header. Scavenging effect so they say. Keep the heat where it's supposed to be I'd always a good call. Boost up boys!

I know, just messing with ya.

On a serious note, why do you think it helped with spool on your setup?

Oh I know man haha, no worries at all. I clarified for others. Well the basic science behind it says that the coating helps keep the heat in the manifold and therefore helps increase the exhaust gas velocity. That velocity helps spool the turbo. But keep in mind I'm not saying you ceramic coat a big turbo that normally spools at 5k and now it magically spools at 2k. Instead it's more like a couple hundred rpms faster. No it's not massive increase but couple that with other things like a nice electronic boost controller and you've got something.

I know how it os supposed to work. I meant first hand experience with before and after testing. Especially with a tighter hotside on yours

Ah ok gotcha, sorry. I wasn't trying to dumb it down for you, I know your a knowledgeable guy. I just thought we were talking in generalities not specifics. My turbo is a small 16g with a TD05H hotside and I noticed boost starting to come on 500 rpms faster with the manifold with its coating and then after modifying the hotside to be external wastegate and coated I saw another 200 or so rpm increase in speed. So that's what I was referring to. Its not massive but you'll notice.

Just an update.

Gave the baby 12a a turbo blanket from Fleabay.  Used some cheap header wrap from Amazon on the Exchaust manifold, and had my downpipe cerakoted.

Underhood is pretty cool.  I can put my hand on the turbo without my skin melting off, however it is not comfortable.  

Underhood temps are good.  Next up is some heat reflective tape on the OCVP until I can find a cheap tubing bender.
