Ceramic Seals at Discount
 

SOLD! Thanks.

I have one set of Iannetti Ceramic seals that I need to sell cheaper than normal. The retail price for Mazda Competition Parts is $2700. My cost is close to $2000.

These are the ULTIMATE seals for the renesis and I recommend them for anyone who wants to make the most power over the longest period. In street usage these should outlast the car or literally not wear out in decades. The beauty of these is that they do not cause the normal wear to the apex grooves of the rotor and are unusually easy on the rotor housing surface due to their inherent lubricity. This same lubricious nature allow these to be used with higher spring pressures permitting better sealing at high revs as well as improved torque in the mid range. They are resistant to warpage or deformation brought about by high temperatures or even great temperature variation.

Although these seals are much stronger than the stock steel seals I don't recommend them to people using forced induction unless they have mastered their tune. These are not for the experimenting crowd. These are the choice seal of racers in the Star Mazda series and the Koni Challenge especially since they can be used over and over and over again.

Iannetti is the ONLY brand that we have used since 1990 other than stock OEM.

They can be purchased here for $1975: http://www.mazmart.com/PartsList.aspx?id=29&n=NEW&m=6

Bump for a good deal.

Good Lord - a piece of history for sale. I would just mount them behind glass and hang them in my bar I'm building next year.

:beer05:

Got 3mm?

I can provide 3mm and we're working on some 2 mm deep groove (FD RX7 Dimension) non ceramics for the purpose of EXTREME boost.

Paul.

WHY DO YOU SELL THESE NOW AND NOT IN A YEAR WHEN I HAVE MONEY!?

*sobs*

Paul

Not sure I would trust the Mazda cast to be deep enough in extreme load situations. There doesn't appear to be much extra material there after making the change in the machining. Of course, it's pretty hard to measure that area without having done a CMM. Just sayin'.

it's already been done for years Mac, just sayin' ....

If I recall the castings for the Renesis rotors are much thinner....

Heard rumors that there wasn't room for long 3mm seals :(

I've heard of a few builds. Just saying I wouldn't do it on Mazda rotors.


It's the depth not the 3mm width that concerns me.


either way this is DEFF not the right place for this. Pm me if you care any further.

I doubt Rick Engman will be PMing you for advice :hahano:

I usually deal with paul. *shrug*

They're good for deep groove 2mm. 3 mm may be possible but like Dannobre said I wouldn't do it. We cut Renesis rotors apart 4 or 5 years ago to evaluate these things.

Paul.

When I was thinking about doing 3mm Ceramics myself; after talking to a bunch of folks it seemed that 1 out of 4 rotors would crack after warm up/break in due to material loss and the motor would have to be torn down and a new rotor installed....a 25% chance of failure-IMO not worth it.

However the FD sized seals seemed to work fine; just have a good shop machine them.

Yes. We use deep groove renesis rotors in a lot of competition motors that we run. It is VERY important to ensure that whoever is machining the grooves knows what they're doing as many a motor has been ruined due to lack of proper knowledge and experience in this area.

Paul.

Yup; I had Speedsource do mine; and even then I was nervous about them...

PS - I wanted to thank you guys for hooking me and Ray up so quickly on the seal and o-ring kits.

Us too.




BTW, wanted to thank you guys again for balancing that rotating assembly with our rotors.

It's an honor to serve sir. I'm also privileged to have Sheldon here who is generally quick to get the parts out.

Paul.

Paul, I'm curious what your thoughts are as to the best option for seals for a boosted Renny motor. I've got a motor being worked on by Brian at BDC, but I'm a bit stumped on ideas for the seals. Suggestions? I ask here because I notice that both you and Racing Beat do not recommend ceramic seals for boosted motors and I'm curious why not?

I'm glad to have been involved in the process. Speaking of which, I will PM you soon. I need to discuss a thing or two with you. :naughty::)

Paul.

From what I've seen and through my limited knowledge I'd say:

1)They're hella expensive.

2)Though, they are more resistant to detonation, they are not invincible.

3)Get your tune right BEFORE you buy them, because if you don't, it's an expensive mistake.

4)They'll last nearly forever on a renesis with a perfect tune due to great lubricative nature and lack of wear + they will not damage other engine components, so its a great choice for a stable engine. Newly FI'ed engine with a less than perfect tune is NOT stable enough to stay detonation free.

Anyone correct me if I'm wrong- Don't claim to be an expert :)

Ceramics of the correct dimensions and properly clearanced are the best for NA and FI if the tuner is totally confident. There are people running 40 plus PSI with humungous turbos on alcohol making 1000 hp to the wheels with ceramics. A motor at this level of tune can only last X runs of the quarter no matter waht seals you use. There are people using steel seals making less than 300hp breaking seals (With poor tune). There are several variables including fuel octane, intake air temps, ignition timing, air/fuel ratios etc that always need to be considered. The approach of some seal manufacturers has been to make seals that will bend and distort greatly when faced with great pressures and temperatures but of course they will kill power when this occurs. My opinion is: Don't create the environment where seal breakage could occur in the first place. When ceramics break they can do more damage than a steel seal generally speaking. In a renesis it's worse than the older peripheral exhaust motors because material can't escape as easily. The strong ceramic fibers can do a number on the internal parts when catastrophic falure takes place.

I'll try to PM you what approach I recommend in better detail.

Paul.

You are correct. These seals I'm selling are not intended for an FI renesis and will be EXTEMELY long lasting with NA environments. For someone who can afford these they would have many benefits longterm. 200k miles with great compression and power on the street would be a walk in the park.

Paul.

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...

i would say that Paul is referring to a cost benefit type of thing? Boosted renasis engine have a way of not lasting 100K. Probaly because we mostly are idiots just having fun--self being a one of the 1st club members.
I wish they had ceramic side seals.

Oh by the way Paul just spoke with S --in need for a trans and to make sure I was one of the 1st on the list for the oil bypass mod.
Have you seen the results coming from converting our cars to a single oil cooler? Nice results --you should look. I see an entire kit???
OD

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.
