So I remember back when I had my uncoated hooker longtubes, a friend had the same set but coated. He could touch his a few minutes after turning the car off. Mine would take a couple of hours before you could work around the thing.

Now that its a turbo car there is a TON of heat.

I think my current design is a keeper, and now I need to get it all coated.

Found a local place that seems to be fair on price. Does anyone know of any super cheap places? Guessing shipping would negate any better price I could find.

What about the coatings? He says he can do the 1600* silver coating like jethot uses, but is that enough? I mean I'm guessing for the metal to turn that color of orange its got to be in the ballpark of 1800-2000* - So do I go with the much less pretty black coating that's rated to a higher temp? My thoughts are that if they are coated inside and out, there won't be as much heat in the metal, so it won't be getting to those ridiculous temps anyways.

So who has coated their diy hotside? What did you use and what did it cost? I'm not really interested in spending $200 on header wrap if I can coat it for $300-400 ish. (But that's pricing wrap from what I have seen in retail stores, can you get it cheap online?)

I have no heat and no air - even just cruising my crossover pipe will make your lower half uncomfortable in the car if the outside temp is anything high enough to justify rolling down the windows.

 

Subscribing, because I'm curious to see what people have to say.

Heat is the enemy. IMO, do everything you can to isolate exhaust heat from the rest of the engine bay, especially on a turbo car. Coat them inside and out and wrap them.

 

And can I coat the inside of the turbine housing? Or just the outside?

 

go over to theturboforums.com and contact fstford i believe (its something to that effect anyways, he owns his own coating business).

You can coat the inside as well as the outside on the turbo housing.

 

Im having overheating problems in 50 degree weather. Wrapping the hotside and a turbo blanket. I wonder if the blanket works better than coating?

 

Header wrap is disgusting.

My pipes are all HPC coated and this stuff is incredible. The most important aspect that people seem to overlook is it's incredible corrosion resistance, and that it does NOT come off, you can hammer on and even expand coated pipe. Unless your pipes are aluminum or stainless, have them coated inside and out if you want your pipes to last more than a couple years. Paint or powdercoat doesn't compare.
Secondly the ceramic coating definitely is a heat barrier. I welded on an HPC coated pipe and it was still hot like 10 minutes later. An uncoated pipe would have cooled in a couple minutes, I was impressed.

I replaced a section of my piping and used that high temp "ceramic" silver spray paint, and it was rusted within a week, god knows what the inside of the pipe looks like where it wasn't painted at all.

Also HPC has a higher temp coating, over 2000 degrees.

 

how the hell do you guys have overheating problems? I never got over 180 with my turbo in 90* weather beating the **** out of it

 

The ceramic coating will greatly slow thermal transfer but the metal will probably still heat up to the same temperature. Your pipes won't sink nearly as much heat, therefore maintaining exhaust gas velocity (heat) to the turbo. So they'd still be hot as hell if you touched them... they just radiate and disperse less heat.

 

turbo is real close to rad.

 

I wouldn't say I have overheat problems. I cruise @ 170 - hard boost will make it rise to 190ish. I'm running a 160 thermostat, stock fans, stock rad, extended lines, cheapo electric pump.

My problem is that heat under hood and in the car.

HPC? high performance coating?

There's a place just a few blocks down the road and I have the car today. I think I am going to run it over to them and see if they can give me a price at lunch.

 

so was mine, mine actually TOUCHED my radiator haha. you guys just need better fans or something, idk....

 

Found a performance coatings location like 2 blocks from where I work - Showed them the car and they said no problem.

$160 for the manifolds
$12.5 a foot for the rest of it - so like 3ish on the crossover and 3 on the down pipe
Didn't give be an exact number on the turbine housing - but guessing on this it wouldn't bad.

Have a silver/jet hot looking stuff - a black that's very flat - and a titanium coating that is their highest temp. Showed me some headers done in the stuff - Its a flat matte sort of silver finish. Not bad looking at all. Said its @ 25% more $ - Probably go with that.

Cheaper than I thought - But I need to tear the car apart and its about a 3 week wait right now on their work
