Here is a link to some pics of my CS pdk build. I will be testing the car on March 12th at PBIR.

Mike - sooooo cool!

What did you do to defeat the traction control, such as brake steer ? In a normal PDK Cayman, if you disconnect the accelerometer that measures slip, et cetera, then the PDK goes into limp mode. You can do this disconnect on a manual transmission Cayman, but not the PDK. This is my understanding from previous Renn List posts. Perhaps there is a way around this limitation, now ?

Thanks

I am not doing the work but it is a question I have asked...

mikew968

Is there any effective way to defeat TC without screwing up sport plus?

mikew968

Who is running pdk and also running psm? I hear it is working well and there is no need to defeat tc. My Cayman is being finished this week and I am test at Sebring this coming weekend!!!

try to track down geoff isringhausen jr, daniel martinson, or mike strommen. all have raced cayman pdk in itc.

First day with the new Cayman. Everything went well. Car runs great and the shifting is awesome.

Went in for my dyno today and found out that you can't dyno a pdk car on a non-4 wheel drive dyno. The pdk trans goes into limp mode and won't "hold" 4th gear to be able to do a "pull". Now I need to find a 4 wheel dyno!

jcastle

still waiting for my 4 wheel dyno as well. pdk dyno is difficult. fvd makes some equipment to fool the ecu, but it's $$$. not sure if the fvd kit is mandatory on 4 wheel dyno.

Hey Mike nice meeting you at Sebring. I was the tall guy with the GTS talking about PDK with you in the pits. I was following you during one session...great driving and the car sounded and looked great.

I finally was able to dyno the car today. The dyno was a DynoJet 424x linked AWD dyno. It took a while to get up on the dyno with the car being pretty low and also took a while for the operator to get a proper RPM reading. The HP was 305.6. I was looking for around 315 so I am going to be 175 to 200 lbs over my min weight. Is there a definitive driveline loss number?

Frank 993 C4S

Mike, you're going to have to start posting pics of that beautiful car of yours!

jcastle

No definitive driveline loss number that I'm aware of. 15% is what gets thrown around.

mikew968

If the driveline loss is 15% then that would be 360 engine which is what I expected. I had heard it was 12.5% DL loss. I will post pics when I figure out how to do so!!!
