Good info, thanks guys. Interesting about the KEP Lite, first time hearing about it. I wonder if that torque figure could be increased with a slightly more aggressive disk. I'm not planning on making 500 ft-lbs or anything but I would rather get a clutch that I never have to worry about being a limiting factor.

I built the motor with Molnar rods, and have T&K head studs waiting to go in with a MS3Pro ECU, LR Super 61 turbo and full 3" exhaust. May sell the S61 and get a Voodoo turbo. So the motor itself should stand up to 400-450 ft-lbs in current form and I intend to be somewhere around there

More clamp load will equal to a heavier pedal but more torque holding capabilities.
A more aggressive clutch disc surface will also have more torque capabilities

Like i said, Spec uses an OEM Sachs PP. All their stages increase surface friction material on the clutches. So yes they will chatter or feel like they're more on/off. But you keep the same pedal feel and less stress on the fork.

Can anyone comment if this is legit? I trust Zims but this seems well below average price for a new Cup disk.

I saw that as well, but it seems legit as there are several ebay stores offering them for around that price or cheaper. Seems the big 944 parts vendors just like to rip us off

These are the cheapest sources I could find:

The KEP pressure plate is also cheaper direct from KEP themselves. (550 USD)

Found the disc for even cheaper:

Now to find the best deal on the release bearing. Seems like $180 is the cheapest.

Does anyone know the torque holding capabilities of the KEP1 + Cup disc combo? Reading conflicting information when I search. Patrick Motorsports says the KEP1 is good to 530 ft-lbs with a stock disc. This sounds really high? If that's true then it stands to reason that with the more aggressive liner on the Cup disc, 530 ft-lbs is the minimum it should take. Then I'm seeing people north of 400 fw tq being told they should get the KEP stage 2 and something like a 930 disc (on web forums like this one). Maybe I'm missing something, but it seems like the KEP stage 1 is fine for 99% of modified 951s. Curious to see at what point people are getting slip with KEP1s if at all.

Your build sounds quite similar to mine and I went through the same decision for my clutch. My first question is why you need 60-2 if you are doing the MS3 pro? Why not just decode the stock sensors? That frees up a few more flywheel options in the larger size. I had all the parts basically to go either way with my car; either S2 or 951. I went with my 951 aluminium flywheel, Blaszak pressure plate, 6 puck Clutchnet disc. I mounted a 60-2 wheel on the front of the crank, but I'm going to try to make the stock sensors work and if that goes ahead, I'll pull the front sensor. I ran this setup on my 2.5 and it is 'driveable' on the street, but it does take a lot of finesse. It gripped really well with the K27 and the pedal effort was close to stock, so I'm assuming the stress on the fork was still acceptable.

I was originally going to do this. However I can't find any documented accounts of people successfully using them on a 951 with MS. I've seen that it HAS been done, but no real follow-up as far as what was needed. VEMS seems to use some kind of purpose built decoder to handle the high tooth count. The MS3Pro manual says it can theoretically do it natively but again I would need to see some actual real world accounts. I have nothing against VEMS but I chose MS because I have years of experience with it and I got a sore-dick deal on the Pro unit... can't beat it! ($750 or something shipped with both harnesses, "used" new in box).

If I were to bolt everything up and I couldn't get them to work I would be stuck with a bolt-on wheel. The only one worth a lick seems to be the Clewitt which is around the same cost as the 60-2 flywheel. I would love to prove the MS is capable of using stock sensors but I'm more focused on having a solid setup that I know will fire up with no worries. A solid signal through the whole rev range with no chance of timing drift. There will also be a Clewitt cam sensor installed for full sequential, so having 3 sensors for RPM inputs would be a lot. I know Audi did this with their Tri-tach system but it just seems like engineering wankery in 2018 when there are other options.

Cool, I'll let you know how the stock 951 triggers work with MS3. I have a cam sensor too... but that is for future winter projects. I'm starting with a distributor and stock sensors first. It's a big project already.

odonnell

What's your schedule for firing it up on stock sensors? I'll go that route in a quick second if you have success.

JustinL

I'm the slowest mechanic in the world... hopefully by the end of summer if I can figure out how to fit the gigantic turbo in there.

Decided to move forward with the TTV flywheel setup, a few others are getting them as well so we are doing a group buy. Currently around $400/person shipped from the UK. If anyone else wants one, there's a posting on the "Porsche 944 no spam" facebook page.

*ahem* there's a guy on Pelican selling the Lindsey 951 push setup, 7000 miles used for $800 (about 70% retail).
