They should seal a lot better than 1pc
Issy from Select Maz in AU reported the highest cranking comp ever in over 25 years in the business with the NRS 2pc seals.
Regards, Sven
P.S. I talked to Ray so I think we are good to go when you are ready. You may want to organise with me which seals you want now as there will be a bit of a production slow down with some new developments and transition into the new material.

So how much more efficient has the seals gotten since I've last inquired about them Sven? I know they were bad *** before, but after months of more work, how much more do you personally feel they have improved? I've been hurting in the pocket since some unfortunate things have happened, that I've had to pay for, but can you please PM me for a price list of your stuff. I think I'd hop onto the 3mm seals and your upgraded springs. Seems like they have no problem sealing whatsoever!

Well the biggest improvement would have to be the micro finishing. The quality of the entire surface is improved with this processing. We have applied this to the springs as well.
The next major improvement will be the new material. There is no like material that even comes close in strength, not even the material we use now. It is by far the best there is.

My goal is to (if possible) keep the pricing the same and simply move everyone into a superior product.

Just installed a set of the 3mm 1 piece greys in a customer's (davin's) motor. While the extra clearancing definitely took a little bit more time, you really can feel how much lighter than stock the seals are. Also, the springs are much beefier than the factory pieces

Don't know, we haven't tried them yet but there is no reason they can't handle what the current seals can handle and then some. If your tune and build are good I don't know that there is a limit on boost you can run.
Sporty runs 40psi and some others run 45+psi. Enzo is going to run 50psi but he wants to do it on 2pc seals.

Damn sounds like these newer seals my infact find the actual limits of the rotary engine. I'm trying to speculate as to what may start to consistantly fail with-in the engine in the 60+ boost range.

For now I'm still recommending 1pc for those boost levels, they are pretty much all that I've been selling for the last few years so that's what we know works. 2pc testing will begin soon in all applications from street, road and drag. The only one who hasn't got their 2pc for testing is Gaby but that's because I will have some other ceramic goodies for him and we're going to send them all at once.

Glassman, would you be willing to post some material specifications?
Specifically, black vs old gray vs new gray? The new gray is better in what way?
Hardness, toughness, stress/strain, yield strength, fracture, elastic limit, etc...? I'm not sure which measurement standards are most typical in the ceremet world but it would be great to see some hard numbers, if for no other reason than to compare the differences between your products.
I'm new here too though, maybe some technical materials information is posted someplace and I've missed it? I've read a bunch of anecdotal evidence but am having a hard time finding anything empirical.
