Car is at the track till tomorrow when I can get it towed. I've got 63500 on the car and make the power listed in the sig... What should I do now?
I had a spec stage 1 and couldn't shift at high RPM's. Rich might be the only one to have any luck with it. 3+ might be too grabby for your power level. If I were you, at your power level I might go with stock again. The stock clutches are very good.I was thinking about a stage one spec clutch. They say they are good to 510 tq. That should be good for a long time for me.
I had the same issue with the Centerforce DF in my 6060 that I had with the Spec 1 in my 3650, couldn't shift on the track. It seems some people have had good luck with them and other haven't, kind of a crap shoot.If you are going to stay at or under 400 rwhp I highly suggest a Centerforce Dual Friction clutch package. You can't beat it for the money and it engages very smoothly. I had one before the Whipple and switched to the DFX after that.
Get your flywheel resurfaced then sandblasted for quick break in time. Also get the pressure plate disc surface sandblasted too. You can also glassbead them instead of sandblasting. This will cut the break in time from 500 miles to about 150 or so. Also get a new release bearing/slave and pilot bearing. I suggest the Mcleod adjustable unit. Pricey, but it increases bearing movement from .500'' to .700'' when adjusted properly. Shifts are much better with the extra movement/disengagement.
I will second the motion of the P51 clutch. It is made by Exedy and is an excellent piece of work. It feels like stock with the pedal a little lower to the floor, but it holds well. I make about 530 rwhp and 490rwtq if this gives you an idea of how good it is. There is no vibration or noise of any kind.RoushStage2 has had good luck with his P-51 clutch, and I have heard pretty good things on the Spec Stage 2+, the general consensus is that the Spec Stage 1 sucks.
Could a clutch be the reason for my bad times recently or would it have nothing to do with it.
