Drag Race Newbie
I purchased a full SB DXD Stage 2 Daily kit from Achtun!ng in Redmond, WA in June 2013. Had it installed by Futrell Autowerks in Portland because cheaper labor and no sales tax. I have not abused the clutch, and my car is a DD; never been drag racing, or tracked; I have of course launched it a few times.
I noticed about a month or two ago that the engagement point seemed to be getting softer and higher (closer to the top of the pedal, as if the pressure plate wasn't applying as much pressure). Concerned, I simulated a 3000 RPM clutch dump by cruising in 6th at about 1500 RPM, then revving to 4500 and dumping it. It didn't grab...just spun and overheated. It recovered eventually, but then it started shuddering a bit on engagement. I've been taking it easy and rolling into WOT instead of hard shifts. As the days have become colder, it seems it is getting easier and easier to break hold and spin. Now at a bit over 18k miles and 17 months since it was installed, it is behaving just like my stock cluch was.
I know SouthBend has a less than stellar track record; has anyone else had issues with major slipping? I haven't had the transmission dropped to check for contamination or anything but short of a main seal leak it doesn't look like there's anything that could be a source. I'm guessing that it's shot as is so I'm about to bite the bullet on a clutch replacement way too early...thinking Clutchmasters FX100 w/o flywheel and reuse the SB SMF. The FX100 is advertised as having "70% over stock holding capacity"; assuming the stock TSI clutch is rated at about 250ft-lbf, would that mean the FX100 is rated at 425ft-lbf?
