Have you actually tried this? I have and the first thing I will tell you is my gt3071r spools faster then several gt2871r builds on the exact same engine. I am actually using the odd ball gt3071r wg version with .86 housing and 90 trim turbine and I am still doing better then others with the same tune and I am using 2.5" exhaust to their 3" exhaust.

Any amount of air forced through a smaller pipe compared to a bigger pipe will have a greater velocity as long as the pipe is not to small to cause a restriction. The tircks with intercooler piping is to use the shortest amount possible and the smallest size possible without causing a restriction.
