Guys, keep in mind that the 1.4bar max. in the GT2 is partly compensating for the expansion manifold intake cooling the air to mitigate thermal stresses to the variable geometry impeller-increasing the volume of a fixed quantity of a gas renders it less dense so increasing boost on the compressor side counteracts this to produce an equivalent power and torque output for a given air-fuel mixture. This means that 1.4bar boost with the GT2's intake setup brings back into the engine an equal amount of air (and fuel) as in the TT intake with its traditional resonance intake. Actually, Porsche advertises that this intake innovation is slightly more efficient for a given power output via the pre-ignition cooling effect-albeit negligibly so-the setup is designed primarily for thermal protection of the variable geometry impeller, not to placate the Greenpeace fruitloops.
