Ive seen alot of pics of other ppls turbos and have seen a common trend. A nice pretty shiny compressor housing next to a rusted fugly hotside. IS there a reason why noone atleast paints it?

ALso would an aftermarket heat wrap be enough to not require the stock tii heat sheilds?

 

We are talking 1800F+. The only thing that will stay on that metal at that point is a ceramic coating.

Yes, a turbo blanket would work much better than stock heat sheilds.

I don't build my cars to look pretty...

I put the stock heatshield back on my BNR and painted THAT with VHT header paint.... so far, its still lookin good a year later!!

 

Its not really prettiness im wondering about its rust, aka corrosion.

 

My turbo rebuilder sandblasted my hotside.
Looked 10X's better. Atleast for 2 months. Then it got to the normal brown color.

Yeah paint won't hold up to those temps. Don't know how paintwill stay on something glowing red.

 

Ok, where would you take the exhaust side to get a ceramic coating?

 

alot of time engine shops know where to get it done....start there!

Says it's good up to 1500F - not 1800+ but it might stick, at least for awhile.

I used some VHT High-Temp paint on my exhaust system to help prevent rust and so far, so good.

no can paint wills stay on the hotside. I foudn out the hard way. USed 1800 F paint ( expensive also ) .

and what happened. Well after driving 15 minutes smoke is comming out of hood I was like WTF. then stopped and noticed my cre paint peeling and burning off.

 

Wow... stink.

What brand paint was it?

just drive the crap out of it so it glows in the dark....

 

LOLO thanks my curiousities are satisfied. It personally wouldnt matter to me since mine is heatwrapped anyway.

 

how big of a diferrence does the heatwrap REALLY make . my 6port seen cooler temps. even after the install because i removed the stuff for the a/c. well its about the same but it never got to warm. plus it was kinda cold out. mid 40's to low 50's

 

It's not something to be concerned about.
Most of it is typically ductile iron / bronze composite or sometimes expensive iron / nickel composite.
Rust is something you cannot avoid.
Try driving the car more often.
Heat keeps the moisture from settling on the metal...

You really shouldn't run without a heat shield of some sort anyway, so either paint the stock heat shield with high-temp paint like YoD did, buy a turbo blanket or go for ceramic coating.

 

I'm heat sheild exempt since the things broke on the rusted Jspec core I bought.

I bet my intake and coolant temps would be drastically lower if I had a blanket on but $150 is a big hit to my wallet for one.
