Single-plate VS Twin-plate on R32 GT-R (everydayer)

[gtrken]

Brendan , unless you are going to constantly drag race the thing , go with Autoclutch and there 9 plate sprung brass button with slightly upgraded pressure plate.

Have fitted it to 3 x GTR's and 1 300ZXTT with no prob.

Micko , rhino and Boosted RB26 have them in there GTR's and Rhino did a 12.4 with his from an off the limiter launch.

Price for BoostedRB26 last week was $800 ish fitted and took one day.

Twin plates are good but rebuilds are expensive .

What about the advantages of the lightened flywheel on the twin-plate vs the std flywheel on a rebuilt clutch?

I have a nismo twin plate and it's fine to drive. Before that i had a 5 puck ceramic single and it wasn't any different to drive. Both weren't very easy to drive but were quite manageable on daily basis.

My advice would be to go for a twin plate, your wife will get used to it. It will be a pain for her compared to other cars she may drive, but unless you put back in an organic-full faced stock clutch in there, all others will be as well.

Thanks Emre, I must also point out that once the engine has been rebuilt it will easily be putting out over 350rwhp considering it put down 302rwhp at only 0.75 bar but was running out of air and fuel (now solved with purchase of 660cc injectors and z32 afms). Would a rebuilt standard be able to handle this sort of power and more knowing I will be taking it down to the drags once in a blue moon.

You should have no problems if it's done properly to the factory specifications or better. 350 hp at the wheels is well within limits of the stock bottom end.

To answer your previous question, if you go for a twin plate a lightened flywheel will come with it, do not lighten that any further. If you decide to go for a single plate you can choose to lighten and balance your factory flywheel, just don't take any more than %25 out.

In fact, re-reading your last couple of post i would urge you to go for the twin plate. For a single plate clutch to hold onto 350hp+ it would have to have a lot less surface area and a very heavy(on the foot) pressure plate unless the pivot point of the fork is altered. Result would be a no more friendly setup than a twin plate that can handle 700hp at the flywheel.

A lightened flywheel will help you accelerate quicker. The mass of a twin plate assembly is naturally more than a single plate, so they compensate it with a lightened flywheel already. In my case, it was still slightly lighter than my single plate setup.

hey VspecV just wanna know, did ur hks clutch feel soft at all? mine's really soft...and i mean soft....

the stock clutch was much heavier than this one, but the bite in this clutch is mad....no slip as yet...

i fitted a hks twin in a r33gtr yesterday and its very soft and take up is very close to the floor

my take up is pretty far off the ground, but i understand that this is adjustable?? correct me if i'm wrong...

1st time i tried it i was like...wat's wrong it's so soft...then it wheelspinned n stalled n i was like...oh my...wrong clutch choice..

Well ladies and gents, we've made a decision on what clutch we're going with. Thanks to Paul and Brett for lending us the keys to the rides for a test of two twin-plate clutches. Paul's has an OS-Giken in it and it was rather easy to control, partly attributed to the power-assisted clutch in the Skyline. I was half comparing to the standard GT-R clutch, and the RG clutch in the Silvia and it came in about half way. Brett's clutch is an unknown twin at this point, and was pretty much close to a standard feel. All in all the wife was pretty happy with the decision to go the twin plate OS-Giken. Thanks again for all the comments.

Cheers
