Advancing Timing
Has anybody attempted to advance their timing by advancing the timing sprocket by teeth? I guess my question really is pertaining to the amount of clearence porsche built into the timing of the interference engine. It's not something I will likely try(little room for error) <img src="graemlins/c.gif" border="0" alt="[ouch]" /> , but I still am curious as to its feasability.

I have tried to advance the timing.I went about it a different way though,the first time I took two of the cam pullies and made one that was ajustable.I used the outside of one and the inside of the other,after a few hours of machining you can get about 4 degreess.
The other way I tried was I made six of the shafts that hold the rotor and offset the taped hole in 1/4 degree increments.
Niether one amounted to anything,other than some bent valves when I went too far with the first way.
The best way is to buy an engine management system.
I just bought a electromotive tec-3,this thing does everything you would ever want.

Are you guys talking about ignition or cam timing? Ignition is referenced off the flywheel in back with hal-effect sensors. Adjusting the cam sprocket will only affect your valve timing. And in that regard, if you want more power, you'd want to retard the cam (intake opens later).
