Hi boys and girls....and others
i was wondering if anyone of you know where i can get a set of iannetti ceramics apex seals !!!
thanks dimitris

jönsson

ask rice racing in australia.. i think he knows.. i have no url to him sorry... he is on this forum.. found him on a big topic about just apex seals...

Dimitri, don't buy them, ceramic seals are not for street use!

Dimitris, are they for you ? you will regret the ceramics unless you drag race the car

RICE RACING

Dont talk through your *** mate !

Ceramics are for every one except idiots like yourself.... We have NRS ceramic seals in total street cars taht have done over 50k miles with almost no recorded wear on the seal !!!! And much reduced wear rates on the rotor housing surface and the rotor seal slots......

This is why Mazda OEM racing department use Ceramics inthe 787B because it is the most durable material you can get period... now do us all a favour and shut the f8ck up since you know little about my product !

A buddy of mine runs the ianetti seals on the street with a ported motor, 3mm ianetti seals, gt3540 turbo, pfc, @ 15.5 lbs. of boost getting 421 whp. with no problems what so ever... Actually drives better than most stockers i have driven...

You know where the door is mate, dont like it start walking

Now anyone else wants to comment on things they dont know about feel free too and I will make you look like the simple idiot you are......

hey guys,

let's not start a flame war in here huh So someone is misinformed about the use of certain seals, happens all the time, just set the facts straight but dont get so upset by it cause you scare away the people who do want to buy your product.

I'm not going to say anything about ceramic seals (I don't know **** about them) but in here (european forum) we usually are rather polite, even if we disagree. I'm rather sure ALL regular posters in this section want to keep it that way.
All I do know about those seals is that should I ever need some, I'll try to find a polite vendor.

travellinbob

Hi, I am sure that Carl Hayward is a dealer of the iannetti seals. He is a prolific rotary engine builder here in the uk and a real nice bloke to go along with it. Very helpfull and honest. Sorry I dont have his details to hand but if you go and look at the mazdarotary forum in the uk he has an add for his buisness.
Hopes this helps.

Oh and give rice a break. i dont know him personally but I am led to believe he knows his stuff and can also be quite helpfull.( a good friend if mine knows him)

cheers, michael.

RICE RACING

I am quite polite and friendly and extend my help to many rotary enthusiasts.... such as Dimitris for example. Its hard to monitor every single sub forum and thread to see what is being talked about realy good products. You may understand the negative implications an opinion can have specialy from someone who wants to push that view. I extend my peace offereing and say to everyone if you want to learn more about it feel free to PM me or read the below post I have put out in other areas to extend you knowledge of this performance high durability product I sell and sell lots of.

**Posted**

Just wanted to share with fellow builders my experience with this *world class* high durability/quality product.

We have been doing some endurance testing with GURU racing (X-Treme rotaries) here in Australia and are very excitied by the data/results we have achieved. We have been doing back to back tests in a 20B ski racing boat which runs a bridge ported 3 rotor water to air IC, 22 psi boost operating at full throttle full load 9000rpm for periods of up to 30 minutes continuous !!! Have done three such race meetings and numerous testing days and the seals are living up to all expectations.

We have the boat running with Ianetti seals in the front and middle rotor and NRS premium grey seals in the rear rotor Comp readings have stayed consistent around the 7.90 kg/cm region for all rotors since run in period.... A leading brand of aftermarket ferrous "steel" seals did not handle a test session without showing extreme signs of duress on leading radius edge

I sell lots of these seals in their two main specifications (black ceramic for NA/turbo race engines *mostly to replace fast wearing Carbon seals*) and premium grey ceramic (best material money can buy !) for unlimited HP rotary applications.

See... that's the way to sell the product.

But I have one question - I read that these seals are not so nice to the rotor housings. Any comments on this ?

RICE RACING

All the data we have shows *our* NRS seals in both alternatives we offer are a factor of 3 times more kinder on rotor housings than OEM seals, they have a much lower coefficient of friction and have better self lubricating properties.

Our seals were independently tested by Moller Engineering (sky car fame) on a 24hr stationary constant motoring rotary engine (runs allthe time!) and they have far reduced friction over any type of ferrous seal and other alternative ceramic seals, wear is neglidgable....

Have lots of high milage (race & street) cars that again have very low wear rates on rotor housing, much less than ferrous type seals... they are a great long term cost saving. we have blokes here who run them for multiple seasons (engines only get rebuilt to fix up side seal clearances & change bearings). Rotor housing, Rotors & Apex seals just keep on getting reused again and again, while other alternatives would destroy rotor slots (flare them out) , wear out hardned surface on rotor housings & wear seal out of tolerances to the point wear compression loss results in lost BHP.

They realy are a great product, initial expensive sure but you make up for it in only one saved rebuild + you get retention of performance of engine for longer.

RICE RACING

Mazda factory racing department back these findings up with their use of Silcone Nitride apex seals & their reduction in wear on rotor housing surfaces as compared to *steel* alternatives for seal materials.

They are tested to be very kind to these parts & allow much higher levels of chamber pressure and speed (boost & RPM) without the assosiated very high wear rates.

These are the only seals for example that will give the same performance and low wear on mating parts like Aluminium/Carbon racing seals but last many many times longer

Hi mates,
for me after looking at Peters ceramics i am never going back to other seals!!!My mechanic (who is the best in europe) was very excited with Peters seals plus i had an excellent service from Peter!!!!!As for the price............

Ps1:you are little crazy down there.....you are trying to do ski with more than 220km/h????????Why dont put a helicopter in front?? (apachi one??)...............
Ps2:People here at greece are paying around 1600us/d for Mazda seals or i am wrong??????

Multiplex

Riceracer, thanks for the tone change I can imagine its very irritating to keep being confronted by missinformation concerning your type of product but unfortunately there are more people in this world that loadly repeat what they've heard then actually state the facts. Thats the world we live in, it does no good getting mad over it

That boat rocks!! Man I'm not much of a boat fan but I wouldn't mind having a trip in that thing

I know jack **** about seals but it sounds that when I am ready to do a rebuild I need to get some more info about these. What sortof price range would I be looking at for FC n/a engine?

Robertio

Are you seeing the same compression for Iannetti seals as steel ones? In the UK it seems the norm that you get much lower compression on ceramics.

FWIW, the Iannettis in my last engine were a huge waste of money for me as they lasted <12k on the front rotor before becoming a large collection of small bits of ceramic. Good old Mazda steel one are going in this time as they are somewhat kinder on the wallet if/when they fail.

hey RICE, have you found any differences or strengths or weaknesses between the Ianettis and NRS?
I know you sell NRS, but hopefully it wont be a too biased opinion.
-Ben Martin

RICE RACING

With regards to compression the differences are minimal (we are talking single percentage points) @ very low cranking speeds, I have found this on both products in one piece style. So far as strength I have seen motors detonated so hard they have blown a chunk out from under the oil filter !!!! and distorted the dowel area on the rear rotor housing without breaking a one piece 3mm ceramic seal ! (personal experience here) On a OEM seal it will shater much earlier and not take such a large detonation.

I only specify on the majority 3mm one piece ceramic seals, they are more resiliant than stock (detonation resistant), they seal well (make same power within 2% in controlled repeatable conditions on a fresh motor) BUT and this is the big ONE! they hold this power over the life of the motor any other seal type will drop off in power greatly due to massive seal wear, slot wear, & rotor housing wear..... Ceramic seals dont have this problem.

The problem you have with ferrous products is they wear so quickly and badly on the major sealing edge (leading radius on rotor housing) that any gain you have running a multy piece seal is lost after a few hard runs, they warp as well, they are very thermaly in tolerant "especialy after market BS steel seals" with quality ceramic seals you dont have problems like this, you can still wear the seal in a bad way but it takes about 100 times longer to f8ck one up & the same applies to the major parts the seal rubs against.

NRS Ceramic Power Seals are the best I have used, and I have used lots of seals

Damn, I'm old...........

I remember Node posting as a noob back in the days.....

And indeed, I really don't think I would ever buy anything from a guy that bad-mouths anyone who doesn't share his opinions.....I know a lot of guys of this type, and I can't say I care much about them

Another thing to try to defend your product, and a WHOLE different thing to start cursing and calling names (even with nice smilies to accompany the bad words)

And yes, I'm an old enough member to know what has been happening with this forum for some time now.....
