What about them...anybody tried them?? I probably will!

The PTS seals :

To good to be true??

GUARENTEED NOT TO BREAK!?

 

No price...they're bound to be expensive.

 

never heard of an apex seal guaranteed not to break before, if they are that durable then they will they guarantee that the seals will not scar the hell out of the rotor housings under normal use?


bogus i say!

 

Actually, those look fairly similar to some pictures of ceramic seals I saw discussed on the forum a while back.

The price was along the lines of, "If you have to ask, you can't afford them."

-=Russ=-

 

lol wouldnt suprize me

 

actually alot of seals are garenteed not to break if used with new housings, like RA for example.

 

Hype. Any seal that can properly "seal" the chamber is a long way from unbreakable. Maybe they should call them "less breakable" seals.

 

I'm sure there is some little dis-claimer like "guaranteed not to break on a properly-tuned engine" blah blah blah. A claim like that should have just a BIT more info behind it - dontcvha think?

Who's raising the BS flag first?

 

this is guaranteed not to break even under detonation and so on...in worst case they will bend BUT it is just to straight them up and re-use them!
Pricetag is about 1000USD for 6 apex seals.....

 

^what? if it bent, wouldn't the metal stretch causing the thickness to change, therefore it wouldn't properly fit in the apex seal groove? idk, they are shiny

 

.....riight.

 

That's just what I was thinking. Sounds like they'd chew up your housings pretty good. Maybe if they're (the housings) new that would'nt happen.

Sounds a little like BS, IMO.

 

Just because they're guaranteed against breakage doesn't mean they won't break. It only means that after paying 2k for seals, they'll replace them when they break.

 

i'm sure its possible if they are ceramics, even hard seals wouldnt chew up the housings if ceramic coated but expect to have a fairly expensive engine rebuild when its all said and done.

 

I dunno, it sounds to me like the "lifetime garunteed" brake pads... They'll never fade, because they're made of a hard enough compound to destroy the rotors first.. Somethings' gotta give, and I'd rather it be my Apexes than the housings..

 

rotary ressurection in calgary ab used "upgraded seals" in all their engines. Same principal, someone on the forum saw Adam (the owner) put one ina vice and smash the hell out of it, didnt break. Though for it not to break I imagine it would have to be more malleable (sp?) which means it will simply wear down faster...

 

There we go, someone who knows about metal fab actually posts a response. You're 100% right.

 

LMAO, alright man, I'll tell you what, I can make you a hell of a deal on these magic beans... OR, I have a buddy selling a bridge for a great price... you can charge toll and everything...

Drop the cash on the seals... we've already got a smiley for ya...

 

Look i am not an optimist about those seals... i just got an offer and wanted to check it out with you guys first!
Here in sweden we have 2 maybe 3 guys that is REALLY good in rotaries that i know about.

So all u say is Bullshit?

 

I have researched these seals, contacted the maker and contacted 2 of there distributors, one in Australia and one in of all places Puerto Rico. They are about $1150USD for a set of six and are guaranteed not to break under detonation, everything else will break but not the apex seals. They are not ceramic material but a steel alloy which they will not disclose as to what material. Abel Ibarra uses them and so does Rocky Rahem from Pac Performance in Australia and if you know those two names then you would know both have race cars that do 6 seconds in the quarter mile. Can't be that bad of a seal if those guys use them and countless other top dragracers are swearing by them. Anthony Rodrigues owner of Maztech another top Aussie dragracer also swears by them and his built 13b's making in excess of 600rwhp he even gives his phone number to contact him about these seals. Take it with a grain of salt but from what I have searched and what I gathered from those that use them they are not bad at all. Especially if you weigh in the fact that you can reuse them even if a motor lets go.

 

Maby it's better you ask what guys who hade and are using them said about them.

This is the best quote from that thread by Anthony Rodrigues owner of Maztech in Australia "OK guys I cant give you the theory behind thermal or molecular properties etc of the seals simply becouse I dont know them, nor do I care from them. Peter Glover asked me for some practical input into the development of the seals and an extra 15deg timing and -15% fuel wont kill them although it definitely caused the dreaded death rattles.
I personally have made over 1000hp with a 13B with them and they loved it, fitted them to an off road buggy that nothing has lived in and they lived, have run 30psi on pump fuel, dinted all of the rotor faces and reused the same seals, endurace testing in a road car to dat has seen 19,000km in a road FD with excellent compression still. They are not that old a product and that is the most we have seen to dat but they are not showing any signs of wear yet.
Grant Williams after 7.66 "I have been trying to beat up on them and they are still proving to be faultless".
Abel Ibarra after 209mph "if my 2 step cant kill these then nothing can, this is the longest I have kept with the same engine".
Pac thanked PTS publically after their 6 sec pass.
The PR agent buys 10 sets plus a month so I am sure they are being put to good use over there.
There are many other racers in this country using them and would not care to admit it because they know of the value they have to their race program and it is not for me to make public.
They will not break, they will bow if you are off your tune up, however most other seals std or ceramic would have broken well and truly before these bow, therefore they protect you from severe engine damage created from seal failure.
There are no bulshit promises or tech jargon to promote these seals just proven results hence the name PERFORMANCE TESTED SEALS. This product was tested and developed in Glovers Blown Datto, Staceys RRG and many Maztech & Pac race applications before the market even knew of their existence.

If you don't belive that he made this statement give him a call 613-9416-9516 or email him maztech@iprimus.com.au I already have and I want a set of these seals!

 

I'm sure they are miracle seals.. But I don't think they are for street use.

If you look at the History of Rotary Engine. Mazda spent great deal of time coming up with right combination of metal so that the car could be used by general public, who doesn't have to rebuild the engine every 5000 miles or 50,000 miles.

I think this seals will chew up the housings in a daily car. I've talked to Ianetti in person and asked about his ceremic seals.. He flat out told me NOT to use it in street cars. I think there are way too many variables in driving on the streets vs. the track. He even said there is no better seals than Mazda OEM seals for the street! Just look at all the amazing apex seals we heard about over past 5+ years.. Hurley seals, Aviation seals, etc etc.. Most people end up going back to Mazda OEM for street use.

 

I am in agreement with herblenny on this one, back in the day, the carbon seals were the racers choice because they didn't destroy the houseings, the down side was the rebuilds every 10,000 kms if you tried to use them on the street.

I am confident that in a racing prepped engine (not us backyard racers((includes me)), but full blown race engines, these seals might be better, but for a street engine there is going to be a compromise somewhere, just what it is you will not know without trying it.

maybe it chatters worse (accelerating wear on the houseing and rotor) maybe its heavier, and doesn't seal as well at low RPM, who knows?

Well, it appears they won't break then. I sit corrected.

They will however break other parts of your engine.
