Ahem, pressure isn't everything... temperature matters _a lot_. You can
have 22psi, but if it's real hot, you aren't getting any more air mass
in the cylinders than lower pressure cooler air.
This is why we have intercoolers in the first place... It has been
stated before on the list that you may be seeing 20psi or whatever,
but you aren't actually getting more power due to the increased temperature.
With a better intercooler, you may get _lower_ boost pressure,
but _more_ power.
I think Ross is just getting his terms mixed up here. The 1380cfm does
sound like a useless number BTW without knowing the pressure drop etc..
