What is the official / proper procedure for balancing the VW VR6 engine?

[TrackRat]

I found one older thread here on balancing a 5 cyl. version of the VR6 engine but no info. on actually balancing it. I have read in other forums conflicting ways to balance the 15 deg. (or 10.6 deg.) narrow angle VR6 engines. No one really seems to know exactly what VW decrees as far as I can tell, on how to perform the balancing properly. Surely "TDIMeister" or someone here must know what the official VW balancing procedure is and why it's not public knowledge for the performance aftermarket???

Ignore the ego infighting in the link below which is a discussion by some performance machine shops specifically on how to balance the VR6 engine. There was no conclusive information as to the "official VW" balancing procedure nor was anyone able to determine if one procedure offered was better than another - which is REALLY scary!

I would think that balancing machine mfgs. would have the correct info. directly from VW but that does not appear to be the case in the info. I have been able to find online.

"The primary balance on a VR6 engine is not straight forward as it can be on many other (not all) engine designs." Either you don't know what those words mean to engineers, or you are typing rubbish.

I'm out of here.

"As discussed you can not reverse engineer the reciprocating mass accurately because any recip mass from 30%-50% will appear to neutral balance."
Nonsense. Scanning is cheap. Once you have a 3D model it is not too hard to calculate the counterweighting.

Did you read my post above? It suggests a simple procedure to put you within 1% of the factory counterweighting percentage.
