So if I'm reading that correctly, the Gen V turns 9% slower, uses 13% less power to spin, and outlet temps are 15% lower than the Gen III comparing them with same size pullies. With the VE being increased 9% as well, I could see you needing some more fuel compared to the same size pulley on a Gen III, but otherwise the cooler outlet temps and the fact it's spinning 9% slower should help to decrease heat and therefore KR.
Running a 3.3 on a Gen III should certainly cause more KR than a 3.5 on a Gen V, the percentages above I'm sure were all assuming stock pullies, the gap between them should increase as you pulley down. Now if you're running the same tune for both blowers, I could see the Gen V running you leaner since its VE is better (even though the outlet temp reduction is almost 2x the flow increase), but assuming you've tuned for it why does everyone keep saying a larger pulley on a V is like a smaller pulley on a III? The article tells us that couldn't be further from the truth, or is that just a general rule of thumb for people who are dropping pullies without tuning?
