Any High boost cars running Rotary Aviation seals???
Does anyone have any bad experiences with the Rotary aviation seals at either low(17-18psi) or high(25-28psi) boost levels?

couple guys in the second gen forum are using them.
uh, somebody important is using them...RETed, maybe? But I don't think the car is running yet.
also remember their warranty is null and void if used in anything other than a completely stock 13B.

I am running them on a s5 streetport... I have had it up to 19 psi with them so far, and so far so good...
One thine about them, is that they are really hard, they take quite a bit of time break in...Max

Umm I work in kilometers but I will give a rough estimate.. I am using premix , both housings are series 5 that were not new, but had minimal wear on them..
It always started fine, never flooded, but I noticed the power came up quite a bit around the 2000 km mark, which is around 1250 miles or so... also the compression kept coming up to about that time, and sort leveled off just after that, the idle vac started around 8 "inhg, with a very large streetport, and has since crept up to about 11-12" at idle guage, I live at higher altitude, the guage is zero'd , the absolute reading from my map sensor reports 16"inhg....Max

Yes, the web page is www.rotaryaviation.com. They have these seals really cheap right now for promotion reasons. They are also available with their rebuild kits. I plan on getting the 20b kit. So far they seem to be holding up fairly well. Do any of you guys with these seals have any idea what the effects will be if they fail? Ceramic seals seem to shatter and destroy rotor housings & turbos when they let go. The new Mazda seals seem to bend if detenation occurs (not bad since this wont cause any damage to everything else, just loss of compression). What about these aviation seals?

If they are so hard, wouldn't they accelerate the wear of the rotor housing?

They are harder than Atkins or Hurleys seals, this is becuase those two companies dont do any type of hardening process, i believe, could be wrong. I spoke with Rotary Aviation and this is basically what i got from them.
They said that they designed thier seals becuse of the weakness, and tendancy to fail that the Hurleys have shown. They specifically emphasised the importance of having much stonger corners than the Hurley/Atkins, which is where those seals tend to get chipped/broken.
They are available in 2 or 3mm, they are 2 piece, double springs.
They have a lifetime waranty if you use them with new housings on an unmodified motor.
They are having a "Promo" special whih is why the price is cheap-$170 for a complete set.
I am ordering a set today, we will see how they hold up pushing 17&25 psi on the t51.

We'll be using them on a few engines here very soon, one of which within a week or two hopefully. These things are super hard but not as hard as the rotor housing surface metal. Long-term wear ought not be a real issue.

For me the reason alone of buying these seals is to get rid of the corner seals!!!!
3 engines and all of them chipped the corner pieces and all of them have corner seal grooves!
I assume these will be great seals and possible even better to use in used housings due to being harder.
Correct me if I'm thinking incorrectly.
