Well my new 7 has a Twin Disc HKS in it .. For the power i'm making it will be necesarry...


What it the difference in feel with a twin disc comparred to a single say 4puc non sprung ?

 

I like my OS twinplate, its much more smooth than 4 puck ceramic i used to have before......a lot more streetable in my book

 

It depends.
There's a "street" twin-disc by OS Giken that drives almost like stock.
The increased torque capacity is not due to a heavier pressure plate, but by the increase surface friction area from the twin clutch discs.

If it's a "race" twin-disc, you're going to have fun.

This is the HKS Twin Disc thats rated for 900 HP I doubt its the near stock one ... The OS Giken was on my list but their customer service turned my away when I called to ask about the specs and feel ...

I was expecting it to be stock , I knew it was going to be harsh .. I was just wondering if there was going to be any slip left in it to get it off the line without chirping the tires . Also I hear the twin disc is actually worse out of the hole at the track because of the lighter flywheel ..

Either way I need this clutch , It should be putting out over 600whp soon ...

 

I just put in a USED OSG twinplate clutch for a fellow on a near stock t2 conversion. The thing bit sorta hard, but no worse than your average act extreme PP and 6 puck metal disc. IT's driveable on the street, but you will look like a jackass until you learn it, and even then you'll get caught off guard from time to time.

OH, btw...I weighed the stock FD flywheel with an FC clutch (fd's fit s5 turbo engines) versus this flywheel and clutch setup and the OSG setup saved 1lb...so I don't really think it'll have any noticeable difference in revving or takeoff as compared to a stock flywheel, unless we're talking about an 87-8 turbo flywheel.

 

Try and get your hands on that a streetable OS Giken twin if you can.
It's very mild - you won't believe you're running a multi-disc clutch!

Almost everything else is race and will be equivalent to a unsprung puck clutch of engagement - ON / OFF.
This kinda clutch needs a little finesse to street.

We got an OS Giken triple on our 20B car, and that thing is a bitch!
You cannot finesse this clutch on the street!
