That's pretty much what it sounds like. I was hoping it was my belts (because that's what most engines sound like with the hood open), but if it's the chains, I suppose there's nothing to it other than a CRIOS mod and/or Pedro Sports Exhaust. In truth, the whine itself doesn't bother me nearly as much as the fact I can't hear the exhaust note at lower RPM.
Something about the higher pitch makes it really hard for my ears to figure out what rpm the engine is at, and my around-town rev-matching suffers as a result. It's not that the car is hard to heel-toe, it's easy when I look at the tach, the muddiness of the sound is what makes it hard to do by ear.
As for my expectations, it's only what I put in my original post, I'm not hoping for power gains or anything, just the well-documented lowering of PS fluid temperature and the so-far-only-hypothetical decrease in A/C pump perceived effort, plus the minor benefits of a harmonic damper.
