Audi S6/S8 V10 (D3) Bellhousing Bolt pattern

[LoganMarriott]

Hello to everyone on the Audi Forum
Im normally more active in the Porsche scene, but im working on a complex project and wonder if anyone here can help. Im looking to join an Audi V10 from the S6 (D3) to a 2011 Porsche PDK gearbox.
Conveniently the Porsche Light weight flywheel has the same 10bolt pattern as the Audi crank, and even fits inside the flexdisc, so that i can use the Audi starter, and have both timing rings (one for the Audi ECU and the other for the gearbox to get engine speed data for its ECU).
By my estimates, the adapter will end up being around 30mm thick, and clearly will take some machining.

What im looking for is if anyone has the CAD measurements of the Audi bellhousing bolts for this motor?

Regards
Logan

Hi,

How did you get on with project. I’m looking to do the same with an Audi V8. Did you get cad drawings or any dimensions as I would be interested in the information.
