Clutch Recomendations
I need a new clutch and welcome any recomendations.
While I would like to keep the car a streetable as possible, do to work & family it only sees time on the quarter mile and the drive there and back. So I am looking for a clutch that is performance oriented.
Car is a 68. 4-speed with 4:11 rear. It weighs 3130 with me in, runs high 11s @ 116-119 mph. Usually runs with 8in hoosier slicks and 60s in the mid 1.8s with the M20 which is going back in and low 1.9s with the M21 which is on the way out.
I have not had a whole lot of luck with clutches over the few years. Don't know what it was but whatever was in the car when I started racing 4-5 years ago lasted the longest (of course car is a little quicker now). It eventually went during a burn out and took my aluminum flywheel with it. The next one was a zoom clutch and in desintegrated on a burn out after only a handful of runs. The last one was a Centerforce DFX. We checked it since we were changing trannys and discovered that it is well worn and has scarred the pressure plate a little and marked up the flywheel a touch (flywheel would be okay with a little clean up, but is being switched to an aluminum).
I know the drag racing is rough on the car, but I do think i can do better with the clutch. I would imagine the burnout is where I am contributing the most wear and will consider toning it down, but any real world experience with good strong clutches? Differnt styles?
