I have an ITR clutch in my setup and after some tuning... it's starting to slip... it's only 10 months old... so wtf ?

I am putting out a bit more power than a stock R... so anyone know when the clutch gives ?

 

250 is the absolute limit IMO...but its more torque than HP....just get a better disc.

I'm thinking something else must be wrong. After tracking my ITR rather heavily, we replaced the clutch at 60,000 miles and it looked like the clutch still had life in it.

OEM clutch on modified car still doing fine over here.

not to be rude but he/she is asking for hp not miles!</TD></TR></TABLE>

OK, well, let's put it another way: we know it's good for 220 HP for a very long time.

Because most OEM clutches are overbuilt designed to handle 20-30% more torque than what the stock engine will produce.

HP isnt really a problem, its torque. My car was used as a commuter for 60K and the clutch feels fine even after 8 weekends this year. I'll be pulling the trans to replace the release bearing in a week or two and I'll take a look at the disc/plate, but I expect it to be just fine.

i figured out my deal with clutch.. and im running 260whp and for that setup i used stock disk with slightly stronger pressure plate (1800lbs) and stock release bearing. i don't ride or burn clutch from launch or anything, i take it easy other than high rpm shifts from second and up. it all depends on how you drive, i'm pretty sure it will hold at 325whp.

 

I put 200 drag passes, a few auto-x's, and 50,000mi on the stock clutch. It wasn't slipping yet but I decided to change it anyway.

I'm currently testing the limits of a stock B18B clutch. 250whp for around 6,000mi and its still holding up

 

So concensus is about 220~.

Hrmph.... well, I have noticed the clutch is slipping only in 1st at random rpm and other gears 2, 3, 4 at 6k+... stragely right after the dual runner (gsr head) comes in...

I wonder if the old PP is causing this...
