About to order some parts to start building the tubing for my PSD intercooler.
It's been touched on many times, but I can't find a definitive answer:
What size tubing should I run?
I'm ordering mandrel bends (exhaust tubing) so I can weld it up myself.
The ATS intercoolers for the IDI's came with 2.25"
PSD's run 3" - same engine size, but more boost.
Cummins guys seem to like 3.5"
I'm running a ATS 085 turbo, Uhaul rebuilt IP, and new injectors; it's good for about 10psi of boost when I can get my up pipe to seal.
I was going to run 2.5", but I'm starting to think 3" may be the way to go if I choose to start upgrading the engine in the future (bigger pump, turbo, cam)
So, should I run 2.5", or 3"?
