I guess renesis does create an extra part to that equation in terms of how much damage the steel seals could potentially do anyhow.

Paul.

Yeah, the housing will be scored to hell at least, although I've heard of ceramic seals embedding shards into the housing after a catastrophic failure so I guess thats worse. Look forward to the PM. :)

Uh...... it was Mazdatrix and AZ Rotary Rockets not Mazmart.

To a layman like me it seems logical to use a seal for FI that will be less likely to cause engine damage . I have come to the conclusion that a detonation event is inevitable in an FI'd renesis engine and anything you can do to strengthen it for that event and not have it self destruct has got to be a good thing .

I'm leaning towards the Esmeril seal for this reason ...... Thought it OK to bring this up Paul as i don't think you have a competing product at this stage ?

That will still result in the apex groove clearances becoming Fubar from all the stress, causing a lot of blowby and requiring new rotors & rebalancing to correct

bump for a great price

What will ?

The Renesis apex grooves are shallow. If the apex seals are getting slammed all that force is concentrated on a smaller surface area of the apex groove in the rotor. The Renesis/Iannetti seals don't ways self destruct. They often just crack and bleed off blowby. Theyre infinitely easier on the housing seal surface in regular operation.

There are other things going on too, but in short just because the apex seal didn't let go doesn't mean you aren't causing a lot of other internal damage.

Got ya .
Although if I had a detonation event I would tend to back off and find the cause rather than keep beating on it .....

Catastrophic apex seal breakage from an FI disaster will waste the housing with all seal types other than seals that are 'soft' and will distort which is not what I want in a seal for long term use at all. The objective is usually NOT to have to tear a motor apart for several years on the street.

Renesis makes it much worse because there's no 'easy' exit for material travelling out of their assigned positions. Broken seals can continue to cause destruction for much longer periods. This is the same reason why renesis is so stubborn to de-flood.

Paul.

The seals that are for sale in this thread are not intended for FI application due to stock renesis dimensions. When we do sell seals for FI renesis I will start a special thread dedicated to that topic. These seals are the 'last forever' NA seals proven to make the most power possible for the longest period.

Paul.

Wish these were legal for my class, bump

I wonder: how would they discover that you use these? It's not like they'd take apart a Renesis at the inspection...

A lot of sanctioning bodies allow ceramic seals to be used and this is the only type designed for the Renesis rotors. These are the official seals sold and used by Mazdaspeed Motorsports Development.

Paul.

Bump, I pity da' fool dat' passes up dis' deal http://www.postmodernclog.com/archives/Mr.%20T.gif

awwwwwwwww how cute, see this is what the 8club is all about

Um; yeah it was actually Mazdatrix; my bad on the name miscue......:(

But I have ordered a few items from Mazmart; and they were all first rate; so kudos all around.

I think reading the descriptions in the first post photos, could lead one to believe they could be used for forced induction, as long as it is 5 PSI or less, correct?

:rolleyes:

Mazdaspeed Motorsports rates the 2mm Ianetti seals for up to 19 psig and the 3mm Ianetti seals for up to 24 psig :dunno:

And the story begins. I have dropped my plans to go forced induction in 2010, and will build a NA motor based on these seals. This RX8 is my daily driver, and adding forced induction is just not in my best interest anymore. But building a NA motor that could last a long time with good compression is in my best interest.

This set is sold. I have some listed on our site at a more standard rate now. Thanks for looking.

Nemesis is going to have a rather neat engine.

Paul.
