looking for some new 2mm seal's and spring's for my s5 turbo ii.. anyone used or know anyone using these seal's ? don't know much about them , but they say they can withstand high boost.. dunno... somebody let me know something please.

Never heard of them.

 

If they're advertising them as "being able to withstand high boost", then they don't understand what they're selling because it's not boost that's a concern for compression seals (what is "high boost" anyways?) -- it's engine knock that's created by load.

I'm generally skeptical of stuff like this but given my own personal experiences with Rotary Aviation in general, I'm very very skeptical as to their long-term quality and reliability.

^^ this guy knows his seals!

I've heard good things about RA seals and terrible things about RA seals. What exactly is wrong with them, if anything?

 

they are made from a harder material than OEM. under detonation, they will warp or bend instead of breaking like OEM seals. so they are better insurance for your engine surviving bad tuning or a shady setup.

the downside is they will eat your housings faster. how much faster? im not sure, but i have a set in my TII, and the motor has about 70k on it, still running with no compression problems at all.

personally i like them, b/c i tune my car myself, and if i make a mistake, the engine will still be ok.

tuners like BDC tend to not like them so much, because they know how to tune well, and dont expect to detonate the motor. they are aiming for long term reliability

 

I bought SCR seals with springs for under 500 bucks in puerto rico if interested PM me and ill give you the number to the place i got them from theyll ship them to you.

 

Everything I've read so far on them has already been said. They're forgiving but when they do go they tend to take something else out with them. Regardless I'm still planning on using them in my turbo 6port due to the fact that 6port motors are a dime a dozen around here. Not really gonna be hurting if I have to replace a housing ya know.

 

I don't mean to be controversial or bring a sour note to a thread like this. Even though I greatly appreciate the efforts that people go through to make the engine stronger and give it hardier parts, I'm always skeptical when it comes to the new gee-whiz, ninja mega-unkillable apex seal not only because of how other seals in the past have scarred rotor housings but also because it's not what deserves all of the research and engineering I think compared to something like prevention of engine knock. Keep that from happening and it won't matter.

Ever flattened seal-springs before? I have and it still requires opening up the engine even though there's no broken apex seal or gouged rotor housing.

If they will bend sooner than break then that would mean they're softer, but stronger, and not harder than OEM.



Are the Real World Solution seals the same as the Rotary Aviation seals? If not, I think some people here might have gotten confused.

 

lets say i decided to use the RA seals (which is what i wanted to use but decided to go with Atkins). would running more premix slow the wear to the housings the RA seals do?

 

I've got the RA super seals in my motor. It survived two 20psi boost spikes with audible detonation and still pulls hard. But then again, I am only hoping for 5-10k out of this motor realistically... it's not built for daily driving right now.

 

That's understandable and I think it brings up a good point: Practical application. A guy like you or me may be quicker to tear our engines down because we're perhaps a bit more hardcore in our enthusiasm or perhaps we like to experiment with stuff on the car knowing we'll put the engine in jeopardy at some point. However, we're in the minority when it comes to people looking to have engine work done. Most normal folks (not us; we're abnormal ) are preparing to spend a decent-sized chunk of money on an engine they want to last in a daily-driven street vehicle. That is who I am catering to in my business and especially my comments on threads like this. Most everyone I've run into, with a few exceptions, want reliable and long-term service out of the money they've spent. I don't blame them a bit. Why fork out a couple thousand bucks and do all of this work on your car for an engine rebuild when there's a legitimate question to the quality of some of the parts used and whether or not there's a chance that they can potentially harm something interally? I'm referring here to the few-years old case of the old Rotary Aviation seals that produced numerous reports, including from myself), of rotor housings getting scarred up in fairly short order.

Gonna be using the Atkins seals myself for my rebuild. Have heard nothing but good things from other people that have used them.

 

Those are the ones I use for my customers. They break-in easily, are competitively priced compared to stock, and can can the power. If one does happen to break, the chances of it destroying a rotor or housing are very small.

it seems that theese super seals remind me of some old technology with the HURLEY race seal-the one with double springs-since this is what RA super seal is. would this still be reliable to 20lbs of boost, keeping a tight fit?

 

I'm going to be using these seals because i like the insurance.

Theyre not needed with a good tuner and or near stock engines.
