I think this is one of those things where what you feel is not necessarily accurate. A 23 mm tire pumped up to 130 psi or some ungodly pressure will definitely feel faster than a 32 mm tire at 65 psi. You will really notice a difference. The point, however, is that though the narrow tire at high psi feels faster, it isn't really faster.

I have the Compass Rat Trap Pass (2.3") tires on one bike, and I must admit they feel slow. It is really hard to get over that "oh these tires feel so slow!" feeling. I know, I know, according to tests they are no slower than narrower tires. But they sure feel slow.

Dynamo hubs are the same; if you turn the axle with your fingers, you feel a lot of resistance. If you put them on your bike and ride, you feel this vibration. When you feel these things, you conclude this thing you're feeling must be slowing you down. Tests show that it doesn't slow you down much at all; but it's very hard to believe it.
