Care to figure out the head loss for us over that 2.5 feet of pipe? I'll give you a hint, not much and no where near 2psi. The intercooler will be a far bigger restriction than the pipe.
I did figure it out, you'll need to be moving 50lb/min of air through a 2.25" pipe to get a .85 psi drop over 2.5 feet of pipe, 1.4psi for 6 feet of pipe. That's ~500rwhp worth of air. At 300rwhp worth of air (~30lb/min) that same 2.5 feet of pipe(2.25" pipe) will cost you a whopping .3psi. I've included a couple bends in that 2.5 feet of pipe as well, just for good measure.
Ok, now this is just silly. Have you measured the temp coming out of a turbo that's working fairly hard? I have, think 220*F+(at 9psi on a t3), in a 150* engine bay it can only LOSE heat. Now if you're talking about the cold side of the intercooler, that pipe should only be 12"-14" long, any longer is poor routing.
Edit: I think I've been beaten to the punch, but I've got maths.
