Duplex Tip Seals
 

I'm curious if anyone here has used the Duplex Apex Seals from HME?

I wanna get a re-build and port done next year, so I was considering getting the rotors machined to 3.5mm so I could use the Duplex seals.

Don't wanna spend the big$ unless it's worth it tho.

That looks to me like an awesome idea!

Yeha, they look great, but I thought I'd ask around first, see what I can learn.

The only problem is that you have to get your rotors machined to accept a 3.5 or 4mm apex seal, and it only shows them for 13B engines, but you'd have to e-mail and ask to be sure.

I'd do your reasearch first.

Ask to see how the seals are at 7000-9000rpm where normal apex seals start to chatter. I don't doubt the benifits @ low rpm, but I'd be nervous @ high rpm.

What was one of my major concerns too, and since I like to run my -SE at high revs it's a big issue.
