Not that much, though it did make more than not being intercooled, and this
was part of the test.

This is true, with the exception the water intercooler system drew water
from an ice box, which is much colder than ambient air, at least for a
while.  A dyno test doesn't have cooler ambient air, simply because where
the dyno was located in our case, the space is very hot, full of paint
fumes, and has horrible airflow.  This I would imagine is not the norm.

This is true.  The engine dyno testing we did was our attempt at
determining what power, temperature, level of boost, etc, intercooling was
required, what of the above brought detonation, etc.

Oh, oh, oh, my 30 HP comment in my prior message was not a true HP
statement - it was merely a sarrcastic comment attempting to say
"Intercooling a N/A engine doesn't really help very much."
