Ceramic Seals at Discount
#26
What I find interesting is that - everyone agree's they are at LEAST as detonation resistant as a metal seal; so why are they are not recommended for FI?
If cost is the issue - then simply say that they are expensive.... but a renesis seal failing can cause plenty of extra damage all on it's own...

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.

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 ?

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.

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.

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.

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.
