VATN Audi 2.5 TDi V6?

[auditude at cox.net]

Hi Per,

Thanks.  Do you have some of this info?:

Are they made by KKK?  Do they bolt up to a stock K24/26 type of exhaust manifold?  Can they work on a gas motor?  Do they need some sort of electronic controller to work, or is it controlled by boost pressure somehow?  Are they available used or cheap somehow?

I'm just trying to understand if this is something that could be used in place of a K24/26/27/RS2/etc.

The only VATN I heard about was the Aerochargers, and I heard they are very expensive and have a high incidence of either being DOA or failure in the field.

Thanks,

Ken
