Clutch is on borrowed time

Well I have been running my 03 with 99,000 miles on, loaded with the Diablo Extreme tune for about a month now. I've read that 2 weeks of that can take care of the clutch in a hurry, now to speed up the process I installed 75hp injectors, and still no slipping, but I'm sure it's coming. Just wondering which clutch to go with, a 550 hp single disc? Or dual disc? Then for the Nv4500 do I have to change the input shaft to be able to change to an aftermarket clutch, I could really find info regarding the 4500 for a 3rd gen so any help would be great!

Do I need to change the input shaft to a different size or something? I thought I saw that once...

Ya on a nv4500 if you want a DD you will need to upgrade input shaft but you can get a good rated single with an upgraded 13" flywheel like they run in the 6 speeds on that input shaft, good deals on either that DD with an upgraded input shaft and cer/cer singles from Valair and thats what we all run

yup!

it all depends on how much power you plan on having if you have to upgrade the input shaft. i'd pretty much say yes upgrade it and get a dual disk, that way you never have to do it again.

Well I don't plan on huge numbers, pretty much whatever a programmer, my 75hp injectors, and a turbo will yield me will be it...

No need to do the hydraulics unless you do the DD and upgraded shaft

in that case i believe that the CON OFE would be perfectly suited to you.

I think I may be going with a SB dual disc for the standard input shaft, seems to be cost effective and should be enough for what I need.

The stocker let loose tonight, I was exiting a 90degree curve in a hasty manner in 3rd, spinning the tires, shifted to 4th spun a bit and boom rev limiter, 5th same thing then I knew. Still holds good through 3rd, gonna drop down to the tow tune until Friday. GOOD THING MY SB3200 DD CAME TODAY :party018: but now instead of going to the track with intentions of ruining my clutch Friday night, I have to install the new one:doh:
