Has anyone had experience with some ceremic seals from NRS Rotorsports in Canada?

 

I have not heard of them. Do they have a website? I tried the obvious www.nrsrotorsports.com and that is not a valid link.

 

Sven Nielsen is his name. He has a batch of 3mm ceramic seals. I have talked to Sven for a couple of times, I told him I would be intrested in a set of 2mm seals to try for my car. Currently he only has 3mm 2 piece seals and some solid 3mm ones. He emailed me some pics of the seals.

 

What kind of pricing?

 

1200.oo

 

Killer Bee Rotaries has ceramic seals listed on their site for $20 per seal/spring set. Why so cheap, could it be a mistake?

RRE1014 13B CERAMIC APEX SEALS/SPRINGS (PER SET) $19.50

Everywhere seems to sell them for around $1000-$1400 a set ($165-$233 each).

 

Something has to be wrong about that. I sent them an email to clarify what the part number consisted of.

 

So I am guessing no one knows much about Sven Nielsen's seals?

Darn, I hoped someone would.

 

Last time i was talking with him i thought he said 800.00
u.s. for a set, but i am not sure and i cant find his phone
number at the moment.

Hi guys
Anyone interested in the ceramic seals being produced, please forward your email address to nrsrotorsports@shaw.ca and I will send you an info pkg with prices and pictures.

Happy Trails

I emailed Killer Bee and as I suspected it's a typo. A set of ceramic seals & springs for a 13B costs $1600 usd - ouch!

That's a good info package you sent me Sven, thanks!
To anyone reading this, also read the thread in this forum called "Ceramic Seal Supplier" if you haven't already.

 

I emailed them and they never replied back. I'm glad at least someone was able o get a response. You would think this is not the first time someone has inquired on that price and that they would spend the two minutes it takes to fix the typo.

 

Anyone else?

I have them in both my 20b and 13bt.
Both are 3mm 2 piece. Haven't run the 20b yet, but the 13bt in my vert has done well so far. I have several thousand miles on it so far (takes about that long to break them in really) and 2 track days and I have 13-14 in/hg @ idle with a large street port with tons of overlap and 9.4:1 compression rotors.
I got a great deal on them btw
Under race conditions with 15 lbs. boost for 20 minutes, I blow-by about 3/4 a quart oil into the catch can. That was about the same as with the 2mm 3 piece seals not that the seals have that much (if any) affect regarding that.
Haven't done a comprerssion test since initial tuning several months ago (before they were broken in) but will be doing one again soon so I'll post some numbers then.

btw, Sven is a great guy to talk to....
