Yes, I do (and did) see your point but even just by making sure the 
x-sec area of the turbo outlet is kept constant or put through a venturi 
if the throttle is larger, and keeping those sizes in the intercooler 
with a decent density of channels, you'll be hard pushed to make things 
worse. In other words, apply a bit of common sense (something which Nick 
clearly has) and you should be okay. If using a donor intercooler from a 
productio engine - how big is that engine, how high is the boost and 
what does it rev to - that'll put you in the right ballpark.

I was intersted to see your suggested reading matter trashed by several 
of the reviewers on Amazon. Put me off buying it :-)
