Hey, ive been reading on the Ra apex seal and i see they have very good luck with them.. but still a few who dident.. now i put there newest batch in my rebuild.. but my question is anyone have a set in there NA that has many miles on them (like 50k-150k) i just want to know how many miles they last and if they will last as long as oem... so if u have a rebuild with ra apex seal with high miles.. tell me how many miles and compression number if u have em... and just in general how itz running...



Thanks


Dustin

Hmm, I'm interested too, but I dont think you'll find anyone with that many miles on them yet. They have only been out for a few years, so at best I think someone would have that many miles on the first generation of the seals. But shoot, I may be wrong...

felixwankel88

yeah i dident think so either but there may be a few peeps who drive a realllllly lot out there

Your going to stir up the hornets nest. If that doesn't do it then...this will

Maybe all the folks that used the RA seals didn't get but 30-40k out of 'em. Maybe that's your answer.

mainly because they where boosting their cars to oblivion and ****.

I have an engine running these seals with a tad over 40,000 miles. It is not my car, but I built it and tuned it. It is a 4-port half bridge N/A engine with high-comp rotors and runs a 250 shot of nitrous oxide.
The rotor housings were new when installed, and inspections of them at 28,000 miles with a boroscope showed no signs of scoring whatsoever. Exhaust port inspection showed a smooth trochoid surface as well.

I believe a lot of these problems has to do with exhaust port design and operator negligence.

There ya go Felix, Scath came and saved your butt.

Got a pic of your exhaust port design?

My engine builder was telling me about an engine he built for a guy in New Orleans over 30k ago, using these seals (Ted A. on the forums as badassrx7 i think) that has the same compression on a single turbo 13brew at 30K miles as it did after break in.


If you beat the hell out of your motor all the time, it wont last as long as the motor that takes the occasional beating.

I can say that mine has 5k now and don't seem to have any probs... heavy pre-mix red lined daily. compression is fine and good vac...

I'm willing to bet that more than half the people with these seals abuse their engine alot more than normal because they feel they have that extra margin of saftey. I guess that why my 94 w/91k original miles still runs perfect. It gets an occasional beating.
