How do you calculate the piping size from the turbo through the intercooler to the intake? I've got a T3 that I'm planning on using, which has a 2" outlet. I've got my eye on an intercooler with a 22x5x5.5 core and 2" inlet/oulet. I'm planning on making 15+ lbs of boost and about 350HP. Will this IC with 2" pipe flow enough?
What can I use as a guideline?

Thanks!
