OK cool then maybe I can PC my manifold too.

I'm sorry, but wouldn't your turbo Lose some of it's cooling efficiency by having the compressor housing painted?
I'm just curious b/c I've heard something similar about painting an intercooler (with the same fine paint that they use to paint radiators). I've heard that when not making serious power, it's not that bad. Though when making some big numbers, it can be a damper on things.
All else aside, it does look nice.

I saw ZERO difference in IATs after painting the front of my intercooler black...

Compressor housing gets hot as hell even if you're not boosting. Why?

Because

it's hot as fuck in the engine bay right next to your exhaust manifold.

Paint wouldnt last a week.

If you want to keep things cool under the hood you need a true thermal barrier coating, swain tech white lightning is about the best out there. My infrared temp gun shows 340 F on the exhaust housing, after a pull on the dyno.

Or you can just be a man and coat it in spray foam.

Anyone that knows anything at all about engines, would know that it gets hot in the engine bay.
I was speaking in reference to the turbo itself.
I for one, already knew that it gets hot in the engine bay.
I have owned and personally modified most of my previous cars.
Just to give a small list: (Began when I was 16 yrs of age.)
*1st car- 1970 VW Beetle
Mods done= Porsche 914 swap.
*2nd car- 1982 RX7
Mods= Headers, Holley 650 Dbl. pump carb., cat-back exhaust.
*3rd car- 1991 Civic Hatch
Mods= None, Only put on 17's.
*4th car- 1995 Eclipse Gst
Mods= Intake, gutted out the Cat, Turned up the boost to 15 psi, Eibach Sportline Springs.
*5th car- 1990 Eclipse Gst
Mods= 20G upgraded turbo, 3" cat-back exhaust system, MAF upgrade to the 2nd gen eclipse unit, MBC.
"And my most recent and last car that I owned."
**1991 Eagle Talon TSi**
Mods= 20G turbo upgrade, Deltagate Mack 2 External Wastegate (Bled into the atmosphere), Full 3" Mandrel bend exhaust piping w/TurboTuff muffler, F.Mount Inter. - 29L*10H*4D, 2.5" intake piping w/Greddy typeS BOV, Walbro 255 intank pump, Busher Racing FPR, 850 cc injectors, S-AFC controller.
Outcome= Dyno'd 350WHP/ 314#FT of torque @ 27 PSI.
Everything mechanical, Done by myself.
Anything Electrical, Done by a buddy of mine's shop.
Now.! I'm not saying that all of the above makes me an expert. But it does make me knowledgeable enough to know that it gets, "HOT", in the engine bay. ;)

Well good fucking job. Your DSM experience has served you well. I dub thee DSM expert. That gives you status, Fucking Moron Status, you winner you.

Since the damn turbo compressor housing itself IS IN THE ENGINE BAY don't you think it would get hot too? REGARDLESS OF WHAT THE FUCK IT'S COATED IN?

Engines get hot. Turbo makes heat. That is why we have INTERCOOLERS. Who the fuck cares about a possible 2 degree difference at the damn compressor housing?

Owned.

WOW! Looks like some fuckin geniuses know how to read, yet don't understand the point made across.
What I wrote was not about what "Kind" of cars I've owned. It was about the fact that I know how to work on them. MORRON! Why don't you take yet 1 more course in English class. Maybe then, you won't be insulting others before you can understand what it is that they are trying to say.
Also at the end of my last post. The First thing I said was that I am not an expert, simply that I know how to work on cars in general.
I guess I'll just say thank you for "dubbing me, the dsm expert solely on the fact that I've own three of them. Thank you very fucking much!
You know it's amazing how one simple question in need of a simple honest answer. Had to turn and become responded by an insulting remark. It just goes to show how ridiculously immature some people can be.

I like this part. :loser:

In my perspective, this didn't have to be a place to be insulting anyone. This could be a place where anyone can ask someone something and not necessarily need be insulted.
Did you ever think about that?
Hence! I asked Sean a question, and ended up getting answered by you with insults and childish remarks.
:) how exciting is this.
I'm sorry :_( don't mind me, I'm just LMAO!

Ok to answer the original question. When you coat a turbo compressor with anything for the most part it will then keep more heat in. Paint, powdercoat, and pretty much any other coating will reflect heat in and out. Yes now that my compressor is powdercoated it will be hotter. How much hotter is unknown. It varies by thickness of material how close it is to the engine how good my heat barriers are all that stuff comes into play. On a side not it has been argued that black is known to hold heat if you coat something with black not only will it attract heat from the outside but also from the inside. So then it becomes a game of witch thing will radiate heat better. The compressor housing or the engine bay. In my case I do not care. If my intake temps get to high I will put meth on it and call it a day. Also one day in the future I will need meth anyway so even if the turbo were to run say 20 deg hotter it would not bother me. I even thought about running a siphon feed meth nozzle in the inlet of my turbo like they used to use on carborated cars. If I feel the temps wont come down with meth this will be my first "cheap" option only to hold the car off for a alky control kit. I will let you all know how it works.

To add to this as well I would like to note that the turbine housing has been ceramic coated as well witch is really good at keeping heat in. This is known to drop under the hood temps by 100 deg in an NA car. My hope is that the ceramic coating witch I plan to do my exhaust in to will help keep the heat out of the turbo and in the exhaust further lower temps under my hood. Also take into consideration I will have very little hood on my car and LLOOTTSSS!!!! of airflow because of this so I will not have the same problems others have with heat.

Thank you Sean. That's all I needed to know. :)

I declare that the heat difference is inmeasureable.

Im am still with braineack if there is a difference it is very little and with that it will not effect me in any way. Now mounting the turbo backwards on the other hand may change some heat characteristics of everything under the hood but I will deal with that later.

Glad you're happy.

Now kill yourself while you're still ahead.

Thank you Faeflora for the back up attack system.lol I like it!!!
