Who has used a coating on their rotor housings or other internal parts?

Company you used?
What you liked or disliked?

 

I was just doing a search for the very same thing. I have a bunch of housing that could you a touch up.

 

no one has used any of these coatings???

 

Don't waste your money! it isn't worth it.

 

i have not heard of any coatings for housings, but i have seen a few coated rotors here and there. the general feeling i get is that they don't seem to do much, if anything.

 

There actually is a couple of solutions that you can find information on in these forums.
One is a Canadian company that uses different grades of coatings (cermet A, B whatever).
The other I think was called turblown (or the guy on the forum had this name?).
They are different in nature. The cermet substitutes the chrome on the housings, while whatever the other one is, it is supposed to go onto your parts more as something that becomes part of the surface itself (IIRC).
They are actually very efficient and useful for the rotary, as they reduce heat absorption and friction, helping with all the heat related problems with these engines, the carbon deposits and they also increase the engine life, as they reduce apex seals wear. Using ceramic apex seals with these seems to reduce seals wear to next to nothing.
Problem is, there is no conclusive evidence -at least for the cermet, IIRC- that they are reliable.
There were threads from users who complained about all sorts of issues with the cermet coming loose, causing engine failure, with the housings being out of specs new and with the housings themselves being damaged (on the outside, I believe) coming from the company.
I am not following the stories any longer, I think some of these issues were resolved. I also believe that there are some members here who are using or have used cermet coated housings, so it would be best if they would report on the issue.
I hope this helps.

 

Sounds interesting... If only I was made of money

 

Thanks for the info.




I hope others out there chime in as the old school 13b 4port stuff is hard to get as well as 12a stuff will be that way soon so if a coating would allow me to use my old housings then this would be good.
I was looking at
http://www.jhbperformance.com/index.php
and would love to hear pros/cons on their product and or any other companies out there.

Thanks

 

for some reason i thought JHB had gone out of business a few years ago. clearly i was wrong. for what it's worth, i have read mixed reviews of JHB's ware in the past and, for myself, never really formed an opinion of them.

if you're interested in the Turblown stuff, you'll want to talk to 1Revvin7 (Elliot).

also, i'm not sure if you've looked into it already, but look into Goopy Performance for refurbishing your old housings. i got a set done about 6 weeks ago. i haven't heard any bad reviews of his work and i should be able to speak of it firsthand in a couple weeks when i go to start the engine.
