Another 997tt clutch question

I wouldn't blame sport mode clutch modulation on the clutch itself. That mode has a pretty ridiculous throttle profile. Press the gas more than ~20% and it opens the throttle plate 80%+, easy to see on an OBD2 scanner.

I felt the same when I got my car 2.5 years ago.
I too am running a sachs clutch and it took a while for me to get used to. That being said, I STILL find it impossible to use from a stand-still and while in sport mode
I'm gonna replace the slave when I pull the motor for some other stuff

maybe your clutch is toast. When a clutch is bad can have high engagement.

Agree with this. BTW, Do you have a relative (brother, perhaps) that is a Saab guru? Your screen name is not something you see everyday.

Well, it puked coolant everywhere and the engine is coming out, so I might do the conversion. Does tapping and drilling to us a GT2 fork really worth it over the bracket and EVOM setup? Just curious.

Other than saving $200 dollars over the EVOMS kit, is there a an added benefit by going OEM GT2 route and tapping the tranny? If not I would rather spend the extra $200 and not put extra holes on the tranny.

996pp, kinda wondering the same thing. I believe a true GT2 setup that the fork is on the other side. Guys have had great luck with the EVOM kit, and drilling/tapping. BUT, what is the benefit of drilling and tapping over the EVOM bracket other than the fork being on the opposite side? Just curious, want to get the best setup possible. I do know the EVOM kit can be done with the engine in, but drilling and tapping, it has to come out. Also, read a few people have screwed up the drill and tap and it was not straight.

I recently
My criticisms of my clutch pedal feel and engagement were the same as yours. I found it to be over boosted, vague and just plain sucked. So very recently, when I had to change my clutch - I had installed a Sachs Motorsport clutch from Evolution Motorsports - I had also installed the BBI Clutch Slave Cylinder Conversion kit installed, along with a GT3 helper spring. The kit does away with the accumulator which uses the power steering system to reduce the clutch pedal effort. Now the clutch engagement is much lower, the pedal pressure is higher (it's pretty much 997 GT3 stiff now), and the overall driving experience I find to be MUCH better.

I am not associated with BBI or EVOMS.
I hope this helps.

As I said, mine blew a hose from the ps pump to the radiator yesterday. I took it to Palafox Imports in Pensacola, which has a stellar reputation as a Porsche shop. Anyway, spoke to him about cooling jackets and clutch. He said he could lower the engagement point. I do not think the engine will have to be dropped, but still waiting to hear. If he can adjust the clutch, I will let you know.

There is no adjustment on the slave to fork pushrod. Typically you will need to lengthen the rod to shorten pedal height.
NOTE: this is one of the reason why I like to install the 997GT2 clutch disk and 764 Sachs race pressure plate instead of the rigid Sachs 2.5 clutch disk
