"camshafts with greater lift AND modified timing ensure optimum cylinder filling, with the inlet valve timing matched to the engine's relevant operating point by a hydraulic camshaft actuater"

Hi,

I'm from Poland, to first time in this forum. I drive audi S6 C5 40V ANK-motor and I'm looking for data for my car like this, that I found, but they are not for my ANK engine. This data comes from Bentley Official Factory Repair Manual:


AYS Camshafts (S8 V8 4.2 40v)
Intake open after TDC 25º
Intake close after BDC 45º
Exhaust open before BDC 38º
Exhaust close before TDC 8º

Do you have and can check this data for my ANK- motor pleas?
I can't find it at all and I don't have this Bentley Book .
My engine is allredy by mechanic, who trys to set up it.

Thanks in advance!
