Exedy Heavy Duty Cutch

[buzzboy]

Hi guys

I have am EXEDY heavy duty Clutch NSK-7056HD in my r33 gtst - just the HD not a button or Cushion. Just wanted to know how much power I can run with out any slip . Also would adding a stronger pressure plate help hold more power and if so what change would I see in the clutch pedal and engagement . My power goal is 230rkw

The official rating for the Exedy NSK-7056HD is 320hp (~240kw) at the flywheel therefore with 230rwkw you'll be really testing it. You can run these with a higher clamp pressure plate to slightly raise this figure however the drive plate really isn't designed for it. In my opinion you would be better swapping to a more suitable kit, such as the R32 listed sports organic, Exedy NSK-7121SO, which is rated to 380hp (280kw).

I got 240rwkw running through one no worries.

So far so good, dunno how long its going to last but i will cross that bridge when i get to it..

How long have you been running it at 240? Do you give the clutch a hard time?what's type of setup do you have?

I had it tuned about 6months ago, I have given it a bit of a hard time a kick here a dump there, climbed a few hills and such..Hasn't failed me yet but i don't treat it like shit..

+1

I'd go for one of these Jap made items also (and am on my 2nd one) with 230rwkw and more importantly 520Nm ! Stronger clamp rating and importantly stronger drive plate and springs.

HHDB or GTFO.

Holds heaps of power, and it's a bugger to get used to so great theft deterrent too
