Clutch slipping / not fully engaging?

[firestarter2]

I noticed today sometimes the clutch doesn't feel like it fully engages. Has any one experience this?

I also noticed some times it feels like there is a dead spot almost like the slave cylinder has gone bad.

Ive driven a manual car since my first one long ago FYI and I only have 1200 miles so its impossible the clutch has gone already from wear(ive never actually worn out a clutch). Ive done maybe 8 hard launches..

It almost feels like when you have more power then a clutch can hold.

Take it in to Ford so they can claim abuse and invalidate your warranty.

I don't think that you can wear out a double disc clutch that quickly, could be a bad cylinder. When I have experienced that feeling, I'm pretty sure the tires have lost traction.
Have you removed the assist spring yet? Or changed to a Steeda?

Everything stock I'll test after the gym I don't think the wheels where spinning. My Lexus has some device that will limit his fast the clutch is engaged but I don't think the stang does.

It says in the supplement that it will cut power to protect the clutch if need be.

Can you make a video of the problem?

Ill try to get a video if its repeatable. It might of been a power cut. Felt fine just now.

I have noticed myself, 3 different times when power shifting from say 2nd to 3rd that I've gotten spin on the clutch. Meaning even though I had released the peddle it didn't fully catch leading to some spin and burning clutch smell. Additionally it wasn't some 8k Shift, it was more in the 5K-6K range. I felt it was unusual given my experience with mustangs

One of the better ways to burn it out in record time. Power shifting???

I've had 13 mustangs, mostly all cobra's, most of them swapped out with mcleod double clutches though the ford units are not horrible in my opinion. With that identified I think if our Gt350's with a double clutch can not handle power shifts at 5-6K on upshift then the engineering input for our vehicles was quite poor, or inherently their is an issue. Its like there to fragile to be used for the purpose they were marketed for.
It does seem that everyone has a little bit of "funky-ness" with their GT350's. They all seem to have their own quirks and weird things.

So TRS7139, I'm assuming from your statement you power shift at 1500? 2000 if your feeling ambitious?

I'm assuming Fords notion of "Track-Ready" meant like most mustangs it can get there if you buy a bunch of other stuff.

You just cannot make this shit up.
So you've had 13 Mustangs, and if I was a betting man I 'd suspect every one of them had a big lump under the hood that was done at 5500-6000 rpm swinging that monster flywheel and attendant clutch.
Factoid.... One of the reasons that there Voodoo grinds to over 8000 rpm's above and beyond the flat plane crank is less rotating mass as in smaller/lighter rotating mass, you know with smaller flywheel/ clutch.
Old habits die hard....think less Vin Diesel, more Michael Shumacher...you know, turn, corners, accelorate, stop, all those neat things those shiny Euro trash rides have been largely kicking the domestics ass at for years, until recently.

So from your statements what we should be concluding is on every Gt350, each owner that "powershifts" above say, 5000RPM's should be experiencing the same issue? The same clutch slippage. That each one of us should be burning our clutch up in record time. (whatever variable constitutes record time) For the most part I'm daily driving my vehicle and in no way can lay experience with my GT350 the way other drivers have been able to take their vehicles to track days.

So based on statements all other drivers that are tracking their vehicles should experience clutch burn out at 5-10K miles(I'm not saying my clutch is burned out 5-10K is just a random number), and therefore if daily drivers who powershift are "". Then by your insulation each driver that takes their vehicle to the track must be ... What?

To address your first statement, you would be incorrect.

Power shifting has always been hard on transmissions, always. Deciding to do it in a pretty heavy mustang with a lighter-weight transmission designed for road-course work is....ill advised.

Maybe Stang99SVT should clarify what his definition of "power shift" is. I suspect it's not the same as the true definition from the 50's and 60's.

Given the pic of "Vin Deisel" I'd say the defination is spot on and probably badly.
I guess I'll go work on my insulation now.

Somebody might want to explain to "fast and furious" what "burning clutch smell" usually leads to, above and beyond driver error.
