What would happen if you cryp treated a rotary? I mean everything, housings, rotors, plates, apex seals, e shaft, everything!



Would if affect anything? maybe the seating of the apex seals is all I can imagine. but i dunno, anyone?

I wouldn't bother, but that's just me.

I think, if it will work, that it might be worth it for me, since i'm gonna be running a high compression motor, with boost.



The extra strength that it gives the metal might pay off in the end and keep me from cracking anything, and with the apex seals, if they could be strengthend, it would be awesome, give a little resistance to cracking because of detonation

basically if the apex seals are the weak link, then cyoing everything else would be sort of a waste, because if the apex seal breaks its going to ruin the rotor and housing most likely anyways.

but if you cryo just the apex seals, they will be a harder metal than the housings and would never seat.

If you want hard apex seals, you should try ceramic or Rotary Aviation.

i don't want them to be harder really, just stronger. What if you did everything but the seals. Would theat help it hold boost, similar to what doweling does?

I think you need to consider what other people are doing before you do that.

There are a lot of people running very high HP without any problems related to what cryoing parts can do for you.

While it can be a small help, it really doesn’t warrant doing it for a engine that would even be under the top stress seen in a rotary.

Typically the parts that are cryoed are side seals like the oil control rings.



And dowling a engine is really more for very high HP cars, to stop the plates and housings from twisting.

I am going to be running 9.7:1 compression rotors, with a to4r turbo, hks blowoff, and custom straight exhaust feeding into a single apex i N1 muffler, no cats

and it will see decent boos occasionally.

so you think it would help there, or would I be wasting my time?

Instead spend the money on a two peice eccentric shaft and some of their hardened engine bolt things (forget twhat their called), heat coat the rotor surface (Rotorsportsracing or Gothamracing). If you really wanna **** money away there's allways aluminum plasma sprayed side housing (Racing Beat) and Ceramic Apex seals.
