I have been considering installing a spec racing clutch I was wondering if anyone has any experience with this type of upgrade any info would be appreciated

 

I do not thinkanyonehas done so. One point you will have to address is the Hydraulic system as it has a built in delay valve. You might want to deal with that as well because without faster engagement, allyu money fora "racing" clutch is likely wasted.

When my stock clutch needs replacement, I'll likely drillout the valve. Not taking it apart just for that mod. I would be interested in how that is modified.

 

This is the first I am hearing about this delay valve do you have any more info about it? Like what it is for.

Thanks

 

I have no information on the delay, but also consider 2006 is likely a dual mass flywheel.
I've not seen specifics on them and am no expert, but from what I've read it was enough for me to avoid installing a more aggressive clutch. They are very pricey and "tuned" to the stock setup.

 

All years run a dual mass. Never heard of the delay valve. Any more on that?

Spec is pointless. My new motor is (was until 2 days ago) stock, throwing 339 ft-lbs on my 2004 stock 70,000 mile clutch and I abuse the hell out of it. No need for one unless you surpass me in torque, then it's back to a 'no one knows' kind of deal.

 

No delay valve mentioned in the Parts or Service manuals. There is a clutch pedal position switch mentioned in the service manual, sounds like an electrical component that gives feedback to the ECU on the clutch pedal position. From experience, there is a switch on the clutch that cuts the ignition about 1.5-2.5 inches onto the swing of the clutch pedal.
If you drive at a steady light throttle in 1st or 2nd gear (2nd is that's how I've done it) and push in the clutch, not enough to actually disengage, you can feel it function.
You can also shift up through the gears without touching the gas when you have the cruise control set and the rpms won't go crazy. Set it in 2nd and then just shift.

 

The Service Manual and the Student Reference Book do not mention a delay valve, only one person here has mentioned it. I think he should explain, as Dumbo said I'm all ears.

I had a manual and I never ever saw or felt a delay valve. I would imagine it would affect all gear changes.

 

The switch allows the car to be started only when the clutch is depressed, it is a clutch interlock switch.

 

Yes the clutch interlock switch does that, the (self descriptive) clutch pedal position switch does it's thing also but they are 2 different components.
