The car magazine article makes little sense regarding the intake:

Quote:
Porsche will also tweak the VTG (Variable Turbine Geometry) system. And finally there's a strong possibility that the Turbo will inherit the GT2's 'expansion intake manifold'. Longer intake pipes mean cooler air enters the engine. The air is less dense but by upping the boost pressure the volume of air entering the engine remains the same. However, lower temperatures bring more efficient combustion. So it's cleaner and more powerful - the holy grail of sports car makers at present.



- colder air is MORE dense, not LESS dense
- lower temps do not bring more efficient combustion, it just prevents pre-ignition and maintains charge density



Noop cooler air means less dense
