Has anyone used these seals?

I am having a spare motor built and these seals have been suggested.

they were originally designed for people like jim downing who need to run an na motor at 10,000 rpms for 24hours not for boost, right?

 

Carbon seals are for na engines. Ceramics are for any application. Not sure who they were originally developed for and why. Ceramics are lighter, smoother, stronger and much, much more expensive. They might survive an extra ping or two vs. steel seals. They are lighter which reduces chatter and floating. Smoother gets you less friction and more power. Rob @ Pineapple claims they are good for 20-30 extra ponies in a 13b vs. a steel seal motor and all else being equal.

 

If your still 2mm, I would use the new Mazda 2 piece or maybe the rotaryaviation seals. From what I've heard, the new Mazda seals only bend instead of breaking under severe detenation. This can easily save the rotor housing and turbos if they let go where as ceramic shatter an destroy everything. Plus their way cheaper. However the aviation seals are stil being tested and so far show signs of doing really well. Their really cheap right now. Check www.rotaryaviation.com for info on these.

 

cant understand how Ceramics could give more power
because of smoothness. the seal isn't running on the
housing it is running on a film of oil.

the new mazda 2 piece seals are made of the same stuff
that the 3 piece seals were made from you try
to bend them they will snap.
the rotary aviation seals are a different story they will
bend, are very strong and are lighter than stock seals.

I spent a little time talking to the Kudzu Racing Team's chief mechanic a couple of years ago. He couldn't say enough nice things about Ianetti. IIRC, they have a slightly different design. It doesn't wear out the slots in the rotor tips. He said that, due to that difference, he could routinely re-use the seals and rotors in the engines he re-built for enduro racing.

 

tks for the input. as cost isn't really a factor (within reason)...Ianetti it is. Looking at breaking the 200mph mark next May!

 

Where do you plan to try it?

 

Nevada Open Road Challenge. I have been doing this event for many years. Last big # we put up was two years ago in a camaro when we ran 210. We also have a mustang that we are trying to get over the 200 barrier. The mustang is harder to do though as it is all about aerodynamics above 185..
