Can I just purchase some high heat ceramic paint from the local auto store and use that?

There are several that are rated at 1200 degrees Fahrenheit for automotive use. FYI, this is not to be confused with the type you use for BBQ grills and stoves. I may try this out on my SSAC topmount manifold as well after I've reinforced it.

Please comment on this.

It doesnt matter the specs of your turbo...save your time and aggravation. The paint from auto parts stores does not work well on high-heat applications, nevermind an actual turbine. I gave my downpipe multiple coats with high-temp ceramic "header paint" and it just peeled and cracked, at least for the first foot of the downpipe. I didn't "bake" it in an oven though (the downpipe was one piece and about 3.5 feet long). It's held up well on the rest of the downpipe, obviously because the rest isn't as hot as the first part.

But there's no way in hell that stuff would stay on a turbine. Either get a professional "swain" coating, or even better (and more effective at heat-control), buy a turbo blanket. You can pick up a good one (read: NOT crappy universal ebay "kits") for about $150, e.g., a boost-logic one:

That's what I'll be picking up soon anyway...the "black" blanket fits smaller turbines (standard T3, e.g.), whereas the "silver" blanket fits t4 turbines.

As I said, it's impossible to stick a 3.5 foot downpipe in an oven. Additionally, the can did NOT say curing it in the oven was necessary. I DID, however, let the car warm up and cool down (idling) a few times to "cure" it, and it STILL FAILED. I'm just giving you my experience...I don't half-a$$ things, EVER. That's one thing I don't do. It will not work at ALL on a turbine.

And you're right, you're a lot better off getting it done professionally, but for the pain it's going to be sending your turbine out and waiting for a company to paint it, as well as the fact that the coating will NOT do nearly as good a job at keeping underhood temps down and the heat in the turbine where it belongs in comparison to a blanket, I'd suggest a blanket.

There's a reason the majority of CART champ cars run ATP products (the champagne of heat-blankets). They work.

If I had the $300 to spend and the patience to wait 2 weeks or so while I send my turbo out to them, I'd get this:

You wouldn't be opposed if you understood the basic concept of a turbo...

A turbo is basically a heat pump. Heat = energy; you WANT the heat (energy) where it BELONGS, in the turbine.

Keeping the heat localized in the turbine also prevents the heat generated from being "dispersed" to other engine componentry that DOESN'T like heat, e.g., master brake cylinder, turbo inlet pipe, intercooler cold pipe, etc.

These turbo blankets aren't used just to keep underhood temps down; just as important is the added gains from keeping the heat where it belongs, e.g., quicker spool time.

I believe I paid $250 ~3 yrs ago...I didnt have to send my turbo in (5 bolt t3 turbine housing)...they had the casting already developed....

I had an ATPwrap inconel heatshield on my 5 bolt T3 housing/T4...it worked amazingly. Didn't have to heat wrap any other underhood components. I'm currently in the process of getting one for fabbed for my new GT32...so if anyone is interested in one for your 5 bolt t3 turbine housing, I've got one available, let me know.

Damn, and I just ordered a boost logic turbo blanket...

Nonetheless, you've got mail....I can always return the blanket...or sell it to wannawangan hah

Whatcha want for it?

I'll be doing a v-band set up since the new T3 housing has a v-band flange on the outlet. I should be able to adapt it.

I will email you about the shield/blanket.

My exhaust tip is inconel, I -must- be hardcore.

That's about as hardcore as you get.

Going back to the subject, DIY coatings may work if you know what you are doing. It takes the necessary tools to prepare the piece(s) (i.e. sandblasting and/or solvent bath) as well as proper cure time of specialized coating.

As for me, looks like it's the turbo blanket for me.

Thanks for your input.
