Does it say how much boost the STG3 is using? If its over 9 psi, its also not a good argument considering OEM strength of the S65.
As I said before, i prefer not to talk about a completely different motor arguing for the actual supercharger because it doesnt translate well for the S65. Thats unfair to those of you still expecting big things from it.

Here's another audi 4.2 positive displacement kit with no loss of torque compared to stock:
I also read that the audi 4.2 is:
1. over square bore and stroke: 84.5 by 92.8 millimetres
2. compression ratio: 12.5
I understand that this impacts the mechanical efficiency of the engine and indeed creates different torque characteristics to the over square and lower compression s65.
