Just want some info on these 2mm seals from rotary aviation to see if their actually stronger as they claim. So far Ive only heard that they flex instead of breaking and looses compression temporarily any truth to this?

 

Although,id rather have it flex than break and destroy my turbo

 

I'm busy rebuilding my engine with RA 3mm seals, not done yet.

 

There's a thread in the search where they discuss this. A long time ago yes the seals were prone to flexing and becoming weak. But its been fixed for a while and people have been having no problem with them.

And there is this. Alot of other threads on them in the Rotary Performance section.

 

39k miles on RA rebuild running 14psi with stock turbo & tmic (previous owner)

 

I have them in my fres an h rebuild, but all I have had time to do is let it idle, So i have ZERO miles and about 3-4 hours running time

 

looks like stock 2mm wins again

 

Still waiting for Rotary Resurrection to chim in. He knows his stuff when it comes to rotary rebuilds.
