Ltusler,
My old 99 was setup exactly the same way except that is was a standard 3.6. Todd even did the ECU, same rev limiter.
The one/off switch wasn't bad on the street. Mine had a delay from bank 1 to bank2 to soften it. Fun car, miss it.

Engine is a 2002 3.6 upgraded to X51 then upgraded to 3.8 by Flat 6. Its running the cable TB. The VCAM+ is triggered by RPM switches that bypass the ECU. Either full on or off. Its a dedicated track car so inbetween doesnt really matter. Protomotive did the ECU tuning. Rev limiter is at 7500 and its a blast at the track.

Don't want to hijack Carey's thread. Maybe we need a 996 3.8 subgroup?
Carey, keep the RPM's up! I had mine at Road Atlanta after a couple of hundred miles on Jakes dyno and a oil change. Just don't hit the limiter or keep it revved to high for sustained periods. Over 3k track miles on mine and it just keeps getting better.

Great news !
I can't wait to see the pictures documenting the build !
Can you elaborate about that valve adjustment thing ? I did not know valves had anything that can be adjusted

That sounds sweet Carey. I am in your camp with removing the AWD parts if you won't see wet/snow weather much. You can always retorfit it. The steering is more communicative this way. My TT has its AWD removed and I like it a lot.

Great Post! And what a great opportunity the big bore build offers. With every year and mod that passes I can see how I too might end up at Mr. Raby's place. Something to be said for building your own unique Porsche.

Thanks Bro. Good info... Yes mechanic decoupled and of course my car is a manual. Have you figured aout the flywheel issue you were troubleshooting?

Three Wheelin'
Yep think it's finally sorted, old flywheel was toast, rattling/shuddering... new FW is in and working much better/smoother. It looks like just one more issue to sort out with the idle valve.
