IMHO. I repeat IMHO. You are overlooking the efficiency and output pulses of the
aircharge. The more turbulent the air charge after exiting the impeller then the
higher the heat level due to the molecular activity. This issue is where the
efficiency and impeller design come in to significant consideration. It is not a
simple matter of PSI levels. Essentially a dirty air charge or turbulent aircharge
will will have a higher molecular temperature and thus may need to be intercooled in
order to
match the performance of a clean or non-turbulent air charge. Vortech vs. ATI.

I have seen both the ATI and the Vortech impellers. The engineering differences are
very obvious. The Vortech design "blows" away the ATI. IMHO!
