It could be.  But if you wanted to beat the horse a bit further, I don't
recall where the attached xls spreadsheet came from (heck, it might have
come from the Laminova site),  you could play with the spreadsheet authors
"suggested" intercooler values for an air to air system, where he suggests
the mediums Heat transfer Coefficient be set to 60 & .Specific Heat of
coolant to 24 for air to air vs. an air to water systems suggested values of
100 and 1.0   ~>

Estimated bhp and torque results for a 2.2 liter engine running @ 22 psi @
6000 rpm on a 70 F day come out:

                 Air                Water            diff
bhp         354 bhp           388 bhp          34
torque     310 ft/lbs          340 ft/lbs        30

IF you keep the "mass flow rate of the coolant" and all the other dimensions
of the intercooler, tube lengths etc. at constant values, say 100 lb/min,
for both systems.  I doubt that's a fair way to assess the difference
between the two systems since a lot of those parameters would obviously
change.
