Bummer, but now you will have a stronger clutch to handle all that bottom end torque!! You could run 295's (might have to flare the fenders a touch) no problem.....of course all that traction makes you wonder what the next weak link will be? It seems the boosted auto 928's hold up pretty good.....I can't think of any that had any real problems? Of course most don't dyno anywhere near as high as Murphys 928 either

The stock dual disc clutch has been amazing for over 5 years of serious racing. now, no drag launches except for my 5 speedGT WC starts and a few tests on the street, but the clamping force seems to be fine for my , was, 335rwhp and now 325ish rwhp. anderson and fan were running up to just a little while ago, the dual disc '84 clutch with no issues with 500 rwhp.
however, i will say, recently, if i miss a shift ever so slightly and not match the rpms, gears and the gas all perfectly, the car can rev without accelerating. (this just happed this season) maybe once every other race, but its still reflective of the clutch not being able to bring the car up to the engine speeds (ie slip)

andrew, andrew, andrew.... 
i have the gts clutch in mine as well and it has held up fine (though i don't do many launches or 1/4 runs)
interesting info on the spec site, thanks for the link. i actually have a clutch virtually identical to the stage 3+ in a twin disc version that i am planning on putting in the racecar. the stock twin disc was worthless after the boost went up and the kevlar one i have now doesn't like to stay adjusted. if all that fails, i plan to do the tilton like mark a.
i would agree that going to a stage 3+ or kevlar disc would be a logical next step, but my fear (as others have stated) is if you go too wide on the tires along with that the next weakest link will break

Andrew is the next weakest link.

Why wouldn't it be possible to use a two stage boost controller to limit the strain on the drive train? What is stopping someone from wiring a micro switch into their shifter gate in the 1st gear ( or 1st and 2nd ) position that would cause the boost controler to default to a lower, more manageable psi. Then when the shifter is in the higher gears the boost controler would go to the higher setting. This would also help with launch times for you guys who like to drag race. If you wanted to get fancy you could even wire it up with a time delay relay for the split second in between gears. I would bet that a circuit board could be made fairly easily to control this as well, but that is beyond my realm. Any thoughts? Does this idea have merit?

I think I'll go ahead and order up the 3+ clutch. And since I don't have plans on moving up to wider tires for a while so they should remain the weakest link for a while.

OK Rod... you got a deal on that one. I'm gonna order up that spec clutch tomorrow. Once I get it, we'll schedule it up. It would be a really good tech session for a lot of people.

Just let me know when, and how many of you guys want to come over?
I'll provide the pizza.
(i'll buy the beer when I have my drivetrain installation party).
