A good example of someone talking from the experience of having actually improved heat exchanger efficiency versus someone just theorising.

Atmospheric pressure has a natural variability which can skew data, unless all, before and after ( A-B ) measurements were captured in relatively rapid succession.
Altering upper body drag can alter underbody drag. The entire vehicles must be measured.
An apparent advantage at the intercooler could have introduced an effect somewhere else. The whole car needs to evaluated as an 'aerodynamic singularity.' Exactly what FIAT and Pininfarina did.
