Question about Intercooling

Okay, in my past experience w/ turbo cars (80's turbo dodges), many of them were using the Powerstroke intercooler. Now, if the principals of turbocharging are the same between a straight 2.2 liter 4 cylinder, and a 3.8 liter V6, then you could deffinately use a powerstroke IC in a buick. I noticed on the above link that the guy is using 3" IC piping!! :eek:

Now please correct me if I'm wrong, but that's some huge intercooler piping if you're worried about losing spool up time on a turbo. Wouldn't velocity be a little more important w/ such a huge cooler (to push the air through to the intake)? We're not talking exhaust gasses here, so bigger isn't always better. Maybe 2.5" or 2" would be better? I know you're flowing a lot more air with 1.8 more liters of cylinder volume, but I'm a newbie and to me 3" intercooler piping seems BIG.

So the bottom line is; Can you compensate for the HUGE I/C by using a slightly smaller diameter piping?
