I dragrace on a very consistent basis. I use a stock clutch basket and plates without a mod. I do use EBC heavy springs that are supposedly 20% stronger. I ran my clutch all year last year. That is well over 300 passes.

When I pulled my clutch for replacement the only signs of wear were on the first plate. The springs were a little blue, but nothing too bad. My clutch did not slip.

My clutch fibers were good enough to put in the Turbo SuperStreet bike when the fibers that were in it crapped out. In fact, we did an individual height check on each fiber and they were all within the factory specs. The turbo bike picked up a tenth in the times with used plates.

It sounds like you needed stronger springs.

My 60 ft times without the front strapped, running stock pipes, stock map, stock height, (OK, a factory stock bike) is about 1.6 consistently with a few 1.5s tossed in. When I pull the front down I do a little better. I'm not a feather weight either. I'm a fat kid on a diet. (I think I'm doing weight watchers, I'm watching my weight increase).

I normally launch at a low RMP so I can let the clutch go before I am out of the 60ft marker. 4200 is the highest I rev and I begin twisting the throttle immediated to the wide open position when I see the "go light".

Stock clutch going on second year of racing. I launch at 4000-5500 depending on the track. I run nitrous also. BUT, I also have a set of clutches ready to go in, just in case.

Only if you are stretched and have 250+ horses.

I launch just as hard as everyone else. If you don't believe me, come and race with me. You don't have to crank the RPMs in order to leave hard. The more RPMs you have revvving the more you have to slip the clutch. If you get to know your bike you can leave at the optimum RPM without having to bog the engine or blow the clutch.

I guess the 2008 has a different clutch,

Actually it does but it's just as good. 1.601 weighing 210 unsuited first time out stock clutch. few more runs and it would have been in the 1.55 to 1.58 range. Revvs right I don't leave super high rpm either, hardly slip my clutch at all. leave at around 3500 to 4000

if you change springs install a clutch slave support to prevent damage
