well you can make a really good assumption as to the position of the 1 Turbo. the turbo is connected to the exhaust system. If the exhaust sytem is line up center in between the cylinder banks chances are thats where the turbo is as well.

Its been speculated to death that the Audi has 1 large turbo(with perhaps 2 turbines). That would be the only concievable reason to have 1 exhaust pipe.

The back pressure of only having 1 exhaust pipe would cost them horsepower
