In independent dyno testing, AWE estimates this particular application to be throwing down some 340 hp at the crank on 91 octane, and even more attainable with ascending octane levels. While not especially explosive off the line--as packaged, the turbo setup really only starts to get its torque on between 3000 and 3500 rpm--power builds rapidly and exceptionally smoothly. While at speed it's simply a matter of keeping the revs in the right place to keep the turbocharger happy... not too high, not too low. And when the turbo's happy, it's guaranteed to keep a stupid grin plastered across your face.
Salas, AWE, and Pure MS aren't calling the project done yet. It's speculated there's still more power to be had, though it's also believed that the stock 2.0T internals have reached their limit. If any further power tuning is to be carried out, part of the process will most likely involved cracking open the engine block and replacing the factory connecting rods with stronger units. And as this goes to print, Salas will be tracking the car with a Stasis Engineering center differential to experiment with a more variable torque split.
All in all, a fine example of Ingolstadt engineering, well seasoned with a generous portion of good old American shock and awe.
