Well heck...these aren't brand new out of the box turbos after all. Seen some mileage, all of them. One would certainly expect some level of drag, of course. I guess my point is, don't expect to pull your turbo off the car and tweak it, and expect it to just spin away until the cows come home (but then, perhaps I'm wrong and they should)! Guess I need to go down to the shop and time what free spinning really means. I'll do that and report back when I get a free moment.

PS: Sorry, crappy mood this evening but since you guys are there, then it's a free audience to bi_ch at. Thanks, I feel better now.
