The thread that I posted and am awaiting approval on is a more detailed version of that thread that you are speaking of blackkarma. It should prove to be VERY useful to anyone on here, even the non turbo guys ;).
The following are calculations figured up using these links:

These numbers are set in increments of 250 RPMs starting at...
^ New concept to us ;). I've got something in store for you guys on here that I'll be trying to get posted in the technical section soon pending approval ;).
Do a search for "how many cfms", the thread should be one of the first ones to pop up, it will explain how to calculate how many cfms you will be getting per RPM and boost level, along with the velocity of the diameter piping you want. Trying to keep the velocity under 300 ft/sec, but as close...
Basically the powerband is bumped down few hundred RPM's, maybe as much as 1000? I still don't see a need for 3" IC piping though, you think if the powerband is getting moved down a lot and critical velocity is being reached earlier on with 2.5" piping, then a bump to 2.75" would be in store...
Can't say for sure, use degreaser on it. Put a dye in the oil specifically made for that purpose after you degrease everything, it will be obvious where the leak is then.
