i see where your coming from... although ive owned two previous turbo'd applications im more familiar with n/a engines. with an n/a engine the smallest point on the system is the choke point so the whole system might as well be the same size (before the choke point that is...) so thats why i said the exhaust inlet size should be relative to the pipe size. i failed to mention i meant between the turbo and the engine.
that would create velocity up to the turbo then the dramatic pressure drop from the smaller diameter pre-turbo to the larger after would spool faster per what wally said?

this is how i understand it now so am i right? please correct me if im still dim the the head, lol. im doing a custom remote build on my 02 blazer (starting at 6 psi and moving up from there) so id really like to make sure i understand the dynamics before i mount this thing
