Jet Hot the Turbo?
Has anyone used a ceramic coating on the center three sections of there turbo? Please post your findings or PM me. I'd like to talk to you.

I've wanted to do it for a long time but it's too costly to do it when a rebuilt isn't necessary. I will have it done when I put them back in.
If you recall bi-state customs has done it on their rebuilds (in blue). There is a pic posted in one of the threads.
Pettit Racing only partialy heat coats what they call the hot spot of the turbo manifold.
btw: jet-hot is a brand name and ceramic heat coating is the actual process. you don't Ghost a computer either.

That's true but it's NOT the 2450 degree "Jet Hot 2000" ceramic coating that I will be using. The 2000 product has a dull flat finish with a choice of blue, black or gray color. The shots your showing me are of the "Jet Hot Sterling" that they market for headers on nonturbo cars because it's only good up to 1300 degrees. That’s a much prettier turbo then what mine will be though. Bling bling.

I thought that the jet hot coating might be to think and make it so the turbine wouldnt spin, is that not true? Also, do they prep it so it doesnt clog the bolt holes?
I had teh manifold jet coated with sterling 1300 and the manifold got too hot and made the coating peel off, would the exhaust housing do the same?
Thanks

I expect it would peal. I think the Jet Hot 2000 product is the only one I would trust on a turbo exhaust due to the heat build up from the back pressure. The rotary motor has extremely high exhaust temps anyways.

I've got my entire exhaust manifold, turbo backhousing, downpipe, midpipe, wastegate downtube, and rear exhaust coated by HPC in the Hipercoat Extreme coating, go to this page if you wanna read up on it:
http://www.hpcoatings.com/exhaust_coatings.htm
and click on where it says:
"Exhaust and Header coatings for supercharged, turbocharged and rotary engines"
You'll get all the information on there, I mostly did this to try and keep the underhood temps a little bit lower, and to prevent oxidation. So far I've been pretty happy with the results, BUT it only helps with the underhood temps so much, I guess since it's a Rotary motor, the coating can retain a certain amount of heat only so much, BUT it hasn't peeled or cracked at all which is a good indication that the coating is very strong. Best thing about it is that since I have a full Greddy racing exhaust that's not made in stainless steel with this coating I really don't have to worry about it rusting anytime soon. My 2cents.

What I am trying to do with this mod is drive my twins harder (15 pounds boost), extend their life by protecting from cracking and get them to come on a little earlier by keeping the exhaust gas temps up. What have you noticed about any of these areas after the coated parts were installed? Lowering the under hood temps would be nice but this is still a turbocharged car.
Thanks!

I have my mainfold, and dp coated with the jethot 2000 coating, but I wouldn't use it on the hot side of the turbo.
I don't imagine it would last very long, and I've heard reports of killing turbos prematurely by keep in the heat.
Could just be hearsay, but I'd rather not find out.

The funny thing about the coating is that it almost acts like a polish job.
I got my UIM done with the sterling silver from Jet hot, and I could NOT believe what a differance it made in performance. Boost came up faster and I even began to see spiking. My efini-y pipe is also coated, and that too made another differance.
I knew this guy in PA....he had a custom exhaust manifold made for his single turbo, and he told me the shop told him "If ya get it coated, your spool time can increase almost by 500rpm"
Someday, I will get my DP and MP coated with the 2000 degree stuff, and maybe even my exhaust manifold. My friend had a 500hp stang. With the regular exhaust, you would literally SWEAT in the cockpit. He had the headers, collectors, and piping back to the muffler coated by jethot. After we reinstalled everything, we could NOT beleive what a temp differance it made in the car. I mean, we went from sweating to no more sweating. It was significant amount and I'm sorry for not collecting any actual readings.

I get my stuff flashed by swain.com. Go check them out. Not sure about the higher temps of the rotary but... they do quality work.

OK, from all my searching it seems that a few people have had this done. I don't know if they sent it out or seperated it themselves. How do you seperate the center section form the turbos?

Found this at http://www.scuderiaciriani.com/rx7/polishing.html#DIS , seems they didn't have any luck coating the turbo's. That was a few years back though, hopefully coating technology has improved since then?

Here's a couple of personal observations about durability of coatings. Sorry, no quantitative performance numbers:
TURBOS: Fagettaboutit ! Between my Jacksonville amigo, Dean Colver and I, we've now gone through three different attempts to coat the turbos exhaust sections, and none of the (hi temp) coatings have come close to standing up to the heat. They all disintegrate within a couple of thousand mile. This includes BCE's Stainless Ceramic and Swain's White Lightning on my car, as well as JetHot 2000 on Dean's car. That adds up to well over a $1000 is coating failure, so if I ever find the a coating that holds up to our turbo rotary infernos, I'll be it's unrelenting herald in the RX-7 community.
ROTOR FACES: After on approximately 5k miles, Swain's "piston" Coating had moderate flaking on most of the rotor faces. The part that stays on is good for cleanup, but personally, I'd rather spend the $350-$400 that Swain would charge on upgrading my oil coolers or radiator. Atleast I know that that will last.
DOWNPIPE/MIDPIPE: 1600F coatings are sufficient. The White Lighting is VERY thick and provides the best barrier here.
TECHLINE COATINGS: I've used the DIY Cermakrome coating extensively on none exhaust exposed components, and I am very happy with it. I've even used it on the turbos heatshields, and it has help up In my eternal optimism, I've ordered their 2000F Black Satin to try on my new turbos. Atleat at $50, there is little to loose. They also have a special "extreme heat" coating call MCS that they only sell to professsionals, but if this Black Satin falls by the wasteland of the rotary inferno, I may try to convince them to sell it to me. I think my ability to promote the product would make it worth their while.
NON-EXHAUST: If you're looking for a professionally applied, hi polish coating that is not part of the exhaust system, I'd recommend BCE or Airborne. Both have ceramic coatings with near chrome finishes.

Wow, well 2 out of three of those are 1300deg coatings but i'm suprised the jet hot failed even though I don't like that company since their 2k stuff chipped off my down pipe.
I will look into plasma flame spray like Racing Beat uses on their aluminum side housings. http://www.flamesprayinc.com/services.htm

I have my BNR stage 2 jet hot coated inside and out.
SInce i had other items added for cooling and heat control I can't contribute what had lowered the intake temps.
But since the inside of the turbos are coated it should smooth out the texture for a better airflow.
The cast iron part was coated the ugly matte black finish and the snails were the sterling "near chrome"
What i have noticed is that after 40 k miles when I pulled the turbos off to do some work on the car, there was no indication of cracking of the housings whatsoever.
There was also less carbon and other by-products that stuck to the surface.
Engine bay is a little cooler.
DP , MP, efini y pipe and UIM/LIM are also coated

OK well I called flamespray inc and they said their stuff blows away ceramic coating but it's twice as expensive since he quoted me $300. It's not teh same company Racing Beat uses but it's the same process. Anyhow, the housing would have to be dissasembled in order for them to do it. They say they need a line of sight and they couldn't go in the tunnels effectively. This could also be the problem with ceramic coatig. I wish I had a brand net set to experiment on, then i'd boost it at 1bar and open it up in 6mo and see how it held up.

Arg, ok I called Racing Beat as well. The tech guy said the process of the flam spray is bursts of the stuff at Mach 2 speed? ...exageration? ANyhow, he said if it was a magic barrier that kept the housing from absorbing heat then the exhaust wheels on the turbos would soak up more heat. Makes me want the R85 single now. He said they use it on their side plates for wear protection. They've never tried it themselves.
