Maybe I'm not understanding this, haven't really looked much into the Gen V. When they first came out it was well over a grand to get hold of one, and I never even considered it because of that. I keep hearing it's a more efficient blower, which to me would mean cooler outlet temps than the Gen III. So a 3.5 on the V would be nothing at all like like a 3.3 on a Gen III, which would have far higher outlet temps. It's an M90, so it's still only moving 90 ci of air per revolution, the V is just doing it keeping outlet temps lower, which should decrease KR everything else being equal. Unless I'm missing something, I don't see how a larger pulley on a more efficient blower is comparable to a smaller pulley on a less efficient one.
