OK whats the deal on this stuff? Anyone else tried doing anything like this?

Like that?

There are several people on here with Ceramic Coatings on their rotors from SwainTech:

http://www.swaintech.com/

SwainTech has a lot of "good" experience with their coatings. I highly recommend them if that's something you are considering.

 

That link is dead. Is that your motor? Did you notice any results?

 

The swaintech link isn't dead. Check your routing (ping www.swaintech.com).

Yes, those are my rotors. The engine isn't installed yet. Maxcooper is another one with ceramic coated rotors and has already noted some lower oil temps.

 

What kind of oil temp drops? I am about to install a oil temp gauge in the pan in a couple shop cars here shortly to verify lowered oil temps. We just did a v12 here in the shop, and after 3 hours of pounding on the car we can't get more than 140 degs F out of it, and it has no oil cooler. I realize everyone has coatings, **** they are now even becoming the same color; only hard numbers will show who's works. I do remember seeing people reporting 1-3 degs, that tells me those coatings are not working as well as they are advertised.

 

Those are the temps Max was quoting (on his 13B-REW), however, different engine and I imagine different testing methods.

I picked SwainTech as a lot of the local top fuel builders recommended them. No offense to you, but I'd pick them again in a heartbeat. They've been around quite a while and have a lot of happy and proven customers.

 

Personally I feel the main benefit of the coatings (on rotors) is to reduce the carbon build-up on the faces. I also have heard of improved fuel mileage on the rotary because the fuel/air mixture is combusted more fully. Only down side I see is the increased exhaust temp since the rotors no longer absorb as much heat. That right where will change the way you tune the engine if you are the type that likes to tune off exhaust temp readings. I would love to see how the coatings effect the air/fuel ratio on a completely stock engine with stock ecu.

 

I was planning on trying some of this CBC1 PowerKote on the rotor faces.

~$35

Just have to find an oven to bake them in...

Coating that you apply yourself are junk. Preperation of the applied surface is crucial.

 

If everything goes to plan will have a side by side comparison here in the next 3/4 weeks.
Numbers will be off an Evo8 that has the intake and exhaust manifolds, along with the turbine housing and the downpipe. I'm going to also see if they will go for doing the turbine wheel also.

 

No offense again, but you'll need to have an impartial 3rd party do the testing and results. If not, it will be hard for people to believe you if you say your product is "better".

You might also look at having the longevity of the coatings tested as well.

 

I guarantee these coatings are the best money can buy, so I really don't need to BS anyone with so called facts as so many other companies do.

As far as the longevity of coatings, I have opened motors making over a real 800rwhp, where valves have crashed through pistons and the coatings are untouched. I have also opened motors after race seasons, where the wear on coated bearings is unmeasurable! But then again I don't expect anyone to believe what I say, thats why I guarnatee these are the best money can buy, that means if you can find better I will refund your money.

 

lol, so does every other company out there. That's why you have impartial 3rd parties do tests and comparisons to validate (or invalidate) the claims.

 

what kind of surface prep do you reccommend?

side by side of something self-applied vs. company applied? what are you comparing?

do you offer a coating or a coating service?

Instead of having two threads running about the coatings, just goto the single turbo section for my responses..

 

Good call. Here's the link for easy reference:
