hey mate,

just a little thing i got told by a clutch dude.

twin plate clutches are expensive to buy and expensive to fix and difficult to get parts for. the japanese dont like to use heavy pressure plates, and therefore to get friction they use multiple plates.

by using an upgraded pressure plate (they can be made to suit your needs) and a heavy duty full face or button style friction plate you can have more grab from a single plate, for a cheaper price and still have the same drivability from a single plate, and will just need a new friction plate should you wear it out.

Paul Thomas has a single plate clutch of the above description in his 400kw (at the wheels) R32 GTR.... thats a good enough product placement for me.

cheers

If say you had 300kW... and were shifting from 1st to 2nd... the engine is going at ~7000RPM the drive train is going at ~4500 (and your gunning it as you drop the clutch) ...

I've had the clutch slip a few times :S

Normal driving is fine. Low boost is fine... and if you get the RPMs lined up better its also fine ...

Would you expect a $1700 single plate clutch to cope with this?

And on the subject of double plate clutches... how's driving up a long steep road in stop-start peak hr traffic? Currently mine's fairly forgiving :D

twin plates can often snap gearboxes, diffs, transfer cases and the like.. Unless you have over 300rwkw I don't think its worth the damage to the rest of the car, never mind the driveability.

There are plenty of great products sold locally new here that would be equal to much of the japanese stuff, personally I'd just be going for one of them.

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
