[same theory as exhaust sizing. to large of pipe and you lose youre heat and it slows down the exhaust pulses but it works opposite for boost. You want lower IATs, so if you can slow the air down by increasing the piping size you then lower the IATs since that compressed air now expands into the larger area and cools. the pressure loss you from increasing pipe size isnt a concern when doing with large compressors like what V8 singles run]

Figured thats the reason, I remember you talking about the cooling effect. I kinda wanted to do a 3.5" exit on my intercooler to help slow down the gases. Make it easier for the air charge to split off to all cylinders in the Victor manifold. Fast air dont like to change direction 🙂
