The design looks to be better than the Mazda design:
http://www.hurley-engineering.ltd.uk/sidsealdig1.jpghttp://www.hurley-engineering.ltd.uk/sidsealdig2.jpg http://www.hurley-engineering.ltd.uk/hme_r..._side_seals.htm The stock Mazda seals get kind of brittle with age. I've had a few break with very little pressure while taking them out of rotors . |
Seems like it would be better because the round edges wont catch on any irregulars on the housing right?Since its a side seal there wouldnt be any detonation there so I cant really say it would take detonation any better.

The only problem I see is that Raduised edge wearing down quicker. Mazda put 2mm rings in the GLC saying that they reduced friction (back in the mid 80's). These mazda GLC's needed a ring job at 50,000 miles.

i rechecked my other engine. i think the old sidehousings can be resused so hard part list needed for the engine is two rotors and two rotor housings . got any lying around ? we can try those new hurleys on the spare engine https://www.nopistons.com/forums/pub...DIR#>/wink.png
