This is so funny lol.

 

Better bring alot of nice T-shirts for peace offerings and I just might be able to keep the boys off ya.

 

Yea I already told Anthony that I may have to call ahead to make sure everything is safe before boarding the airplane

 

Has anyone ever used Atkins cryo treated apex seals?

 

for the record, no. i haven't used those. however, you may want to start your own thread, because this one has a lot of personal stuff that may hinder your progress.

 

i have had great results with goopy performances apex seals

 

Is there any additional info on this or any updates? I mean on the apex seals, not an update on Days of our rotating lives. Lol

 

Goopy apex seals and nothing else.

I was curious about goopy vs Als actually. They both seem great but the Als seals have been available longer so more feedback.

 

I've never heard of ALS/E&J seals breaking, even with severe detonation. I've only seen chattering on the housings and losing compression after 30k+ miles. I just recently put some in mine and I noticed it doesn't pull as much vacuum as it did with the OEM apex seals.

 

I have some brand new super seals and race springs for sale if you're interested. I'm never going to use them as I've parted ways from rotary. I paid full price but not selling at full price! One 13B set only!!

 

i agree , ive opened 3 engines with those seals and all 3 with very very bad chatter marks

 

What caused the need to open those motors? Compression?

 

So what you're saying is there No perfect seal, well that's lame. Am I asking for too much?lol are the chatter marks with the Als seals so bad that the housings can't be resurfaced?

 

50 k miles on stock seals........ but with my cooling mods at the plug bosses.

I think it comes down to this. There isn't an aftermarket seal available today that takes care of the housings as well as the factory seals. NA rotaries go well over 150k with the factory seals. What we run into with turbo rotaries is trying to find a seal that is strong enough to not shatter during detonation or preignition. This has resulted in seals that can resist breaking but tend to wear into the housings. When I opened my 52k mile and 20 year old original motor to replace the coolant seals a few months ago the housings looked very similar to Barry's. Hardly any noticeable wear. I'm willing to bet with the ALS seals I have in there now that even though I've only put on 2k miles the housings are already showing more wear. Time will tell, but if this motor loses compression within a couple years then its back to the stock seal and just keep the boost down.

EDIT: It would be nice if companies like ALS/E&J and Goopy could R&D their own premix which might be able to reduce the rapid wear we're seeing.

 

yes , the seal was wasted and chatter marks very bad

 

the ones i had issues with the housings were trash . but this is the only info i can provide from experience .

i only use super seals

 

Well sh&t...how many miles did they last and were those motors premixed? Need to get an idea so I know what to expect. I might even pull the motor out and go back to OEM if need be.

 

I'm going to be getting a rebuilt motor from a reputable builder and am going with goopy seals after some research for what it's worth.

 

I have over 10K miles on my engine with super seals. The car pulls great vacuum at idle and runs like a champ. I did not rebuild my engine, lucky 7 did with the owner before me. I am running 14-15lbs boost with the GT3574R turbo.

Speedjunkie rebuilt his engine with Goopy seals this time around with stock ports.

I am partial to the stock oem seals. 15U on this website rebuilt his engine with stock apex seals. I tuned his engine and we had basically no knock anywhere in his map. We pushed the tubros and ended up using 99% duty cycle (still rich) tune. Backed it off to about 85% max duty cycle for every day driving. He did a shake down in 100 degree+ pueblo heat at 5000 ft above sea level track, got the air temps up into the 80's C (against my advice) with the stock intercooler, and the car ran flawlessly. He obviously needs to upgrade the intercooler (like I advised) and he might upgrade his injectors and turbo in the future

 

Well I have an Adaptronic ecu and would like to try my hand at a little tuning on my car so I would like an apex seal that can take a more than 1 detonation, however I hope this feature of the seal is never needed. I do have some prior experience tuning a Subie with a Link G4 ecu many years back but I will definitely take it slow.

 

Good work Barry!

Was searching some and found this, sorry for the old bump.

Carry on

 

Whats the latest and greatest in the world or apex seals. I am rebuilding a 13BPP for road race application.

Are Iannetti (IAS) Silvers really the magical no-fail ceramic seal every road racers should run?

 

NRS would be cheaper but yes. Ceramics all the way in n/a engines if housings are mint.
