He's claiming 445 hp on pump gas, so hey, good for him.

The problem with rotary engine is no one is willing to dyno and test them and compare new ideas or design issues. I know that the FAA does not approve of the cryno because it would be considered a major alteration. Also, a lot of parts are alcad, anodized, and heat treated. If a avaition cylinder head/barrel was cryno treated it would cause major changes to the piston ring and vavle seats. Meaning alot of new supplement would have to be changed. What happens when you cryno a nitrited barrel?
You make a good point with the different metals and expanision rate. I could magnaflux a housing, get it treated and then maganflux it after or do a dye pen check to see the out come.
This is kinda like the cermacoating the rotors discussion. I wouldn't mind doing it if I can get proof that is lowers knocking in the chambers. If not its just a waste of money and just something to add to your mod list.

Well said ERAUMAZDA, seems like someone finally understood what I was trying to express. I'm not saying in any way that it is a loss of money, just expressing my concerns. 
As no one really seems to know what the exact materials are used and treatments done to them, how can we know how it really affect those parts. I did not mean to hurt anybody's feelings!
Ohh, just a though like that, if I can finally find some time to tear down my old blown engine, maybe I could bring some of these parts to work and analyse them with the spectro gun (not sure if I have the right name for it). It would give us a good idea of the materials used and what processes could be used to improve them. Something to look into. So many Ideas, so little time :shrug:

Well, it is a 13B-REW, cryo'd rotor housings, apex seals, side seals, corner seals, apex seal springs, corner seal springs, side seal springs, oil control rings, oil control ring springs, dowel pins, tension bolts, e-shaft, front and rear stationary gears, Our Stage III streetport (not some secret port that he has "secret") oil pressure/flow mods. We basically did the works to this motor. Some how we are now "Sportcar Motion Technicians"

O-town, if you want more personal info, go look into the Rotary performance page. Not many people here have done this route.
For those of you that DON'T KNOW, it's impossible to get anything certified by the FAA. The fact that they haven't approved it, doesn't mean crap, and is irrelevant. There's a reason why the EAA exists.
In my professional opinion i think it does work. The AF & Army are using it, and it's all been well documented.
In both situations it's used to increase the longevity of the parts being used.
Take that for whatever that's worth to you.

it's all about how much money you got, and what the hell do you want to do with it.
O-town talk to ron about cermacoating the rotors. He's done it on his own engines and such
