Did anyone ever tried doing cryogenic freezing in a 13b before? If yes, what are the results? Is it possible to do this on a rotary engine? Thanks for any info... JP

Cryo-treating engine components can be very beneficial, but you don't want to do everything. The main place it works well are the oil control rings.

Why not everything? Can you elaborate in this one. Is ceramic coating would be a better alternative and considiring price wise? Thanks JP

Well, what do you expect it to accomplish by cryo-treating everything? The oil control rings show a lot of benefit (wear reduction) from cryo-treating. Very little benefits have been seen elsewhere, in our experience. You're welcome to try whatever you like and report your findings back to us.

Ceramics are a whole 'nuther matter. Lot's of good things to do. Rotor housings, rotor faces, side housings. Ceramic seals, of course. Apex seal spring tips. We're working on a process for side seals, too, but that's a tricky one. JHP Performance (see the ad link at the top of the front page of the site) is the only place that is really competent with rotary engine parts.

For doing ceramic coating on the engine, what are the parts that really needs this? Can you give me a list, if it is not a big hassle? Thanks JP
