So I have been watching some of the video's peddling these and on paper they look like magic. 

I have a r34 getrag with a nismo supercoppermix  and its amazing to drive, just holds the power but the box is noisy and I would like a little more room power wise. 

 

So the claim is with the new dampening design in the Uniclutch I will get "near" factory levels of gearbox noise without the dual mass flywheel. 

The torque ratings are very high so power seems like no issue, 800ft/lb will be near 1000hp on an rb26.  

 

So the only question I have is pedal weight,  it will be going from pull to push.  I have an injury that means an overly heavy pedal will not be do-able. 

 

Any one used one yet ?

From what they say, the pedal weight should be less than most comparably rated clutches. So.... perhaps you shouldn't worry? The lower end of their range is supposed to be stock pedal weight or lighter, and the race end is supposed to be "surprisingly light", from what I gathered from (likely) the same vids.

Speaking to them over email at the moment, they did suggest the track model might be better for 1000hp which I imagine is covering themselves. 

 

Getting a straight answer on which flywheel to use is proving tricky, might be easier to just call them. 

 

Any recommendations on a pull to push conversion ?

Been looking at ORC and ATS but both state specific to their clutch.

Track version is now out for the GTR. 

Got this when i asked about track version still having RDC, which is good news. 

 

"All UniClutch’s have silent shift - even the track version. So never any chatter . Track has Quad drive noise dampening which has less angularity than dual drive RDC, but it’s stronger, and will still dampen noise in a Petrol vehicle without a dual mass flywheel . Would be a little noisier in a diesel if the DMF has been swapped out. But that is usually 4x4s and there is a 4Terrain UniClutch tuned for that type of vehicle - ie a Patrol.

 

Still no detail on which flywheel to use with the BNR34 nor a recommended pull to push conversion.

From Uniclutch 

 

"For the flywheels, both the R32 and R34 GTR are very similar and share the same UniClutch fitment kit so you can purchase whichever you like. Just be aware that you would set it up according to the flywheel you buy. If using an R32 GTR flywheel, setup the UniClutch like an R32 GTR.

Yes, you will need a pull-to-push conversion. We are working on a pull type UniClutch, however, this is expected near the end of the year. The OS Giken stuff works great."

 

Trying to decide between these two flywheels -

Any others I should be looking at ?

would a NPC one work?

and here's their catalogue:

(I am not affiliated, even though I keep recommending their shit lol... I am going to buy a Xtreme clutch soon)

Just some day one info. 

It is heavy, the flywheel being built in makes for a solid setup.  Will try and weigh with a flywheel to compare to a direct clutch or nismo twin.

Also the advertised torque is peak, which is not unsurprising and explains my previous conversations. So real torque is about 1000 FT/lB, plenty for a 1000hp GTR.  

Considering mine is making 600ft/lb wheels, 650-80 ish fly(?) lots of room for more power :)

      R32 Gtst - Track Car

      By bcozican · Posted

      Thanks... yeop I think anyone thats had to compete or travel more than the usual home track situation gets it and prob even those that havent yet had to do it ... its just harder and costs more fullstop As one goes through this, prob like yourself, you gain and appreciation of effort - almost regardless of the result - but the result can add to it on top This year I did enjoy it alot more even though it was harder ...which is actually good!

      Thanks Santa (the neverending trials of the 400,000klm, 400kw, RB30, manual swapped Stagea)

      Hey Matt, no I think I've misled you...I'm not sure that the ECCS power supply to ECU had 9.5v, just that the ECU reported 9.5v.   Link got back to me pretty quick and suggested to check the IGN power supplies to the ECU Pin 24 is the IGN key signal, which is working OK (ie battery volts with key on IGN) Pin 31 is "IGN power supply" and sure enough that is giving 0v with IGN on So, back to a car side problem, which is good because at least I can work it out here. On the down side I don't have a wiring diagram for Stagea so its the old fashioned trace and check task. @Stick180 I did double check those fuses are OK (I double checked all IGN fuses) and I also pulled and swapped the IGN relays at the driver's knee as a quick check with no change....but something is wrong there somewhere

      RB25DET with solid lifters - which cams ?

      By Dose Pipe Sutututu · Posted

      FWIW I run Kelford 264/272 9.6mm and still retain VCT. VCT is great, enables all that low end torque to help bring on the turbo earlier compared to a non VCT motor.

      Awesome effort and result, well done. I understand you wanting to get that 1.30 but the reality is this is a super quick car already with road cars being in the mind 40s, its hard to realise how much is required to go that much faster! The other thing is, having done Targa a few times from NSW, the cost and effort to travel that far to a track and city you don't know, and then deal with things not going to plan, that is a huge extra effort on top of everything. And once you've got all that sorted you need to drive it too! Anyway, well done for taking on such a big adventure, I hope you enjoyed it among all the hectic pace and pressure
