I'm thinking I should jet coat this sucker. The reason being is because I assume it will corrode and flake into the turbine, let me know what you think. If so should it be coated for 1500 or 2000 degress. Thank you!

 

i made one and sprayed it with VHT high temp manifold paint, rated at 1300F max, and its been holding strong.

 

is there a trick to that high temp paint? just wondering because i tried to use it on a manifold once and it just burned off.

 

no trick as far as i know...did you make sure you got the one that was designed for exhaust manifolds? its rated over 1300 degrees, VHT makes it.

its on Perfek360's little single came coupe. seems to still be holding. problem is it turns a funky brownish color everywhere it was handled before the manifold was used. best advice is dont touch it after you spray it, handle it as little as possible cause the paint doesnt set up til it gets hot. this manifold sat painted in my house for months.

before heat, at install time:


after handling and heating it up (running it):

 

My thoughts would be a very good cleaning of any oils/handprints etc then bust out some 120 grit and go to down then spray

 

This is exactly what i did before I sprayed it, then I used gloves to put it on to keep it grease free. It didn't get discoloured but it did fade a bit.

 

i think the stuff i used was called fireball or something gay like that. works fine.

 

I wire brushed, then soakd my v6's OEM headers in a parts washer for a day.
Duplicolor 2000*F paint applied for 30m @ 450*F was flaking off & actually producing smoke within a month.. And that's just N/A LoL!

Unless VHT is better than duplicolor, I vote powder coat it, or don't do anything.

 

did you just say powdercoat a turbo manifold?

 

If you powder coated it, it would just melt right off.
