What clutch setups are you 600 + rwhp guys using?

[03 svt]

I've got a fidanza 4.3 in mine now and it holds fine until you hook it up at the track. it slips when you shift. I called them and they said the pressure plate just doesn't have enough clamping force. So i can't get the car to 60ft for sh!t I run 11 o's at 130mph. Just trying to figure out what you guys ar using before I go and buy a twin disc

I have run the Ram HD, Fidanza 4.3 and currently the Promotion 760.
All have worked very well.
The Promotion is my favorite so far.

Ram 900, stock flywheel (resurfaced), stock input shaft.

Now: RAM HD with steel fly / 26 spline input / FR TOB with LFP retaining sleeve
Possibly changing to Centerforce DFX clutch though

Is That full weight car your running? What rpm do you launch at to get 60ft that low? My fidanza worked fine until I dropped the hammer at about 5k with slicks and that was it it's slipped ever since when trying to launch

With the Ram and Fidanza I was launching on 26" slicks and 100 shot of spray.
Launch RPM varied from 3500 -5500 depending on track conditions.
I was consistantly getting 1.5x 60' times.
The Fidanza lasted about 2.5 years of drag racing and TVS testing.

I now have 28" slicks launching on a 2 step from 4k and up.
My best ever of 1.46 was on a well prepped track and the 2 step at 5K.
The car has the full interior, roll bar, FLSFC, solid and tubular K.
There is also a 6 gallon IC tank in the trunk.
