sven, remember i got your 1piece gray 3mm seals? well, rich and ihor over at IR performance are finally putting them in. i will let you know how everything turns out!

 

Good news Davin! I'll bet your excited to see this thing running. Any chance you want to upgrade to 2pc seals??? LOL

 

nah, i like the durability of a 1 piece. i am not sure what i will be doing with my motor yet, but wanted the expendability of maybe making big power down the road

 

So has the still been re-fired up.
There are a lot of 1pc junkies out there.

 

Sven,
Won't the 2 piece seal better than the one piece?

 

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.

 

Hi Sven,what was the comp on cranking??

Brent

 

I believe Issy told me it was in the 140+ psi on 3mm 2pc

 

140psi on 3mm seals Whoa!

 

Yea that's what Issy reported. The wedge design was slightly different but sealing should be close to the same.

 

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.

 

The new material will offer all the benefits the current material gives only better. It is substantially stronger and second to none.
My goal is to (if possible) keep the pricing the same and simply move everyone into a superior product.

 

what kind of boost can we run on these new seals .

 

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.

 

we were running 30+ lbs on the stock mazda seals which do you like the best the 3mm single or two piece.

 

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.

 

Yea it's on pg 2.
Black seals NLA and the new material fracture toughness is 11 MPa

 

Very cool, thank you. Sending a PM to you when I reach 15 with this post.

 

Sven, please work on the 2mm springs.

I guess the only game in town for now is for 3mm seals. Who does a good job grinding the rotors to 3mm?
