Clutch accumulator and/or slave issue?
I have another thread going on but wanted to start another to focus on this topic..
When starting the car, the clutch pedal is extremely hard to depress. This sounds like a common symptom of the accumulator failure.
However, when the car is running the clutch is extremely hard to depress only if I try to do it quickly. It's completely impossible to accelerate fast. If I try to shift quickly I get too much resistance and it feels like something is going to break.
I made the mistake of trying to accelerate hard today, and the clutch actually didn't fully engage when I shifted into 2nd. It sorta caught, then ran up to the redline
... Not sure if this could be the clutch going bad...if I shift normally and give it full throttle, there is no slipping.
Lastly, If I depress the clutch pedal slowly, it's feather light.
Does this sound like it could be caused by bad slave/accumulator? Or is there something else I should think about before I bring it to a shop?

Sound like the slave accumulator. They share the power steering reservoir to an extent, sometimes fluid can leak from there making pedal action harder.

Anyway, do not understand why you would want to do that when you know your clutch has a problem.
Yes , looks like leaking/defect diaphragm

Don't think so.

I let off once I saw the tach rising like that. Guess I just got carried away, I did just get the car a day or two ago. Now it's going to wait in the garage though until I can take it in next week.

Had the same concern, more often than not it is the accumulator, but during replacement it may be better to replace the slave cylinder as well as replacement usually goes hand in hand. do keep us posted

this is exactly what happened to me, and I am replacing both
same symptom, pedal hard to depress when the car is cold prior to starting.

Hoping to take it in tomorrow, I have some new tires on the way and they should be here tomorrow or wednesday. Do you guys know how many hours of labor an indy shop should charge for replacement of the slave and accumulator?
I think I will need both... clutch pedal feels sort of 'gritty' and makes a noise during depression. The only weird part is that I'm not leaking any fluid, which seems to be the usual indicator of a failed slave cylinder...

Do you have a really good competent and trusting technician to help you with the TT stuff? If not, maybe your local PCA club president or one of the guys here can point you to the right/good shop...this makes all the difference in the world...

I'm taking it to IMA motorsport in VA. They seem reputable, they have relatively good reviews online and specialize in Porsches. They have a machine shop and do some custom fabrication too. We'll see how it goes *fingers crossed*. There are a couple of other shops in the area if this one doesn't work out.
