The chattering I am referring to is not noise chatter, it's a shimmy which kind of shakes the whole driveline. At higher take-off rev's it doesn't do it, but it is very difficult to not suddenly over rev, back-off the throttle, and then stall....or launch in an ungainly fashion.

Now, lets talk Fabspeed...
Put mine on last night. They changed everything! I used to drive most of the time at 2200-3000 RPM's, and it seemed a good normal operating zone. Not anymore! The engine just seems so happy at higher revs now. It sort of reminds me of the old RX-7's. By ear, it sounded like you were doing 3000 RPM"S, and when you looked at the tach it would be reading 5 or 5500. They are a little loud at first, but once the cats warm up they seem to get quieter. They are a tad louder than I'd like for some situations, but all in all I am very pleased. They also help me better match engine and clutch as well. I went out today, and in the sun the inside of the pipes looked like s**t so I got out the dremel and assorted compounds and went to work polishing the insides. They look much better now, but not near as nice as the outsides. Note to Fabspeed: For the price it seems you people should have done this. In a month they'll probably be black inside so it won't much matter...
I'm about done messing with this car for awhile, I hope!

And you: hybrid turbos, zero clearance please. A trailer, and a tow vehicle. Then you can start with your Radicals or Caterhams. Darn, your list is getting shorter.

On the Fabseed bypasses... I bought mine used, and they were quite shiney, inside and out. A year later and they are still shiney, even on the inside. I'm a bit surprised about how clean the exhaust seems to be on the TT. Anybody else notice this?

Just to get this clear, what components are in the clutch kit you have - I can't believe its a "GT2" kit as you say since these are like stock to use. Is the disc one of those organic one side, carbon buttons sprung items which VB is marketing.
Thanks

chris-
thanks for keeping me in mind.
let me know how you are making out .. im very interested and you can understand my concern for getting this upgrade and then having an impatient cab driver hit my rear bumper b/c i stalled ... somehow empathy for driving performance cars in nyc really is not very high .. go figure!!
Btw, i drove a friends 993TT with crazy upgrades (600hp, etc) that had a GT2 clutch and lightweight flywheel .. i was shocked at how easy it was to operate .. as easy as stock.. no chatter, no stalling, fine in reverse... but, im not sure exactly what he had in there.

I have a GT2 clutch that has been modified with 20% more clamping force and a LWF and it engages like a stock unit. If its engages like it has a hair trigger, you have a race disc with agressive friction material. GT2 units start to give up the ghost with torque levels at around 525-540 lbs ft. If its chattering, its not a GT2 clutch with a Porsche part number.

JJB - Sachs labels their highest pressure plate setup for the 911ish cars as a GT2. In 2004 they increased the rating to 1100nm or almost 800 lb-ft. This was about a 20% increase from their previous GT2 setup. The discs used have a sprung hub with organic material on one side and carbon on the other. The carbon does break in rather quickly and it is as tame as a stock setup, but with much better holding capability. You can use the stock RS type clutch disc, but it will tend to start slipping if the car starts crossing the 500 HP range. I have the same setup in my own car and have no issues now with any slippage, and for the street it is a gentle as a pussycat. I actually wish that the clutch pedal was a little tougher to operate. It is too easy for my taste.

I'm used to driving the car now, probably 7000 miles with the LWF and as long as you are careful, no real issue at all.
