Clutch Slip and New Clutch Advice

I had my cam gears and powerFC tuned yesterday for my car and when getting a baseline dyno run in high boost (1.2 bar) the clutch woulnd't hold the power and started slipping.....

Although high boost doesn't create a lot more power than low boost I think its the sudden jump in torque (from look at the dyno printout) that causes the clutch to slip....

Anyway I'm looking at around 220-230kw @ the wheels and I need a clutch that will hold this.

I know the best solution is to get an Exedy/OS Giken/Nismo twin plate but I don't want to fork out $3K for a clutch right now. Can anyone recommend me a good clutch that will hold on to this much power ? and costs...

I'm looking at Exedy/Daikins and also the UAs ones at the moment...

lumpy heheheh yeah not bad Nismo ones are softer than OS Giken which can be very grabby.....GTS25T one won't suit GTR though. Have heard Jim Berry clutches in Qld do tough single plates might be worht a call. I just wish for the money I spent on the single had put it towards a twin.. Can't you get a Honky special? Might know of one sitting around somewhere will find out...

So the Nismo are softer than the OS... cool thanks for the info Richie. Let me know if you find a clutch.

Ed don't think so.... cos people me and you both know (hint hint) are getting theirs for between $2-3K right and this is pick up in HK. If then we add the cost of shipping a 30kg clutch to Australia it will be close to $3K!

yang!! when did u buy all those stuff u rich boy...:D (powerfc and all that... i expect u to smoke me next time we meet! )

i have a single plate heavy duty exeddy and i am not that happy with it... its too soft in my view... (feels even softer than the stock one for some reason)

go for a 2nd hand twin...

my mechanic told me a twin plate will last shorter than a single plate... why is this so ? anyone know?

and boosted RB26, ive never seen a twin plate selling for 1k... might be a damaged one ?? :)

I recently got a Daikin Organic clutch and its very nice. Cost me sub $500 (got a friendly discount) and pulls so much harder than the stock clutch (as u would expect when the stock clutch was warn).

I created a thread for discussion on it lately over here:

BoOsTeD_RB26 - really? I haven't seen that many but I've never really been looking out for them. But yeh I'm looking for a twin now I think unless I can find a really tuff single...

Jon - haha well I got some of the stuff when I was in Japan but never got around to fitting it... the powerFC was a late thing.. only just got it :)

I've heard the same thing about the singles plates for GTR... not a single person has said that they last..... so I think I'm gonna get a second hand twin plate.... but damn their expensive. I know Andrew sold his twin plate OS Giken for less than $1K i think just recently damnit but before i knew mine was slipping.

Btw man I met Joshua from proconcept.. he said he worked on your car all summer haha....

forgot the single and go the twin plate yang won't regret it.. keep an eye on here and performance forums for one for sale or try an email hikari they get some 2nd hand stuff sometimes or jms in Adelaide get stuff all the time.. Everyone I know inc me heheh who went a single regretted it they just don't seem to hold in a GTR... twin plate will luv u long time if you look after it they don't like being slipped. the nismo ones seem to wear a bit quicker than the OS Gikens and Ogura's HKS ones meant to be good as well...

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
