For lulz, read Page 8 of the DTI report.
Where, apparently, according to the DTI expert engineer's theory, not only can outside air ENTER the intercooler through leaks in the intercooler, the moisture in the air will condense due to the intake charge pressure and then flash back into steam in the combustion chamber, causing a rapid increase of pressure inside the chamber, causing the ECU to inject more fuel.*
So... you have:
1. Air flowing from the atmosphere, which is at 1 bar pressure, into the intercooler, which is at 2.5 bar pressure.
2. Fuel injection air metering being done inside the combustion chamber, not at the MAF/MAP sensors like in every other car in existence.
Bravo.

I think we've discovered perpetual motion. :hysterical:
Next time there's an investigation, can the DTI
please hire someone who actually knows how cars work?

*When water enters the combustion chamber, as it does when you use a water injection kit, the water flashing into steam cools down the charge air, making it denser. In effect, you are increasing charge density by
reducing charge pressure. The engineer is probably thinking of a water kettle, where adding OUTSIDE heat increases system pressure. Which is the opposite of what's happening here. Here, he's adding outside COOLING to the system.
Of course, that would work if air could travel from a lower pressure area to a higher pressure area.
