Thanks for the note DeWitt, the answers to your questions are exactly what I want to know.   What is the effect of a stock IC on the performance of aftermarket turbos? 

I am admittedly ignorant of things turbo related.  But, I do have a cup full of common sense.  When I read that a particular IC is 50% or 55% or 74% or whatever % efficient, all I ask is that someone smarter than me, ie., those on the list that sell "aftermarket" turbos and make no secret about it, ASSUME the numbers to be correct, and then tell us what practical effect, if any, that stated efficiency [ineff] has on the "performance" of the turbochargers they sell.  Really, this is a simple hypothetical:  If you assume that an IC is ___% efficient at ____, then what, if any, effect does that intercooler have on the performance of a turbo?

I mean hey, if a person is being sold a $1,400+ turbo, should he not also be told that oh, if you really want the maximum performance from the turbo, you will also need to spend $? on an IC?  I can see how such a statement would effect sales, but, if honesty is what we seek....
