I'm kinda worried of ill effects to crank, bearings, etc....

Like CAI's and hydrolock, it's a issue that is talked about a LOT, yet there is no widespread problem with pullies like this...or waterlogged intakes for that matter.
Here's something from UR's site (who sells a ton of them every day)
This is a fear many prospective owners have and it is a valid concern since we are dealing directly with the rotating assembly. It is, however, a fear with no basis in fact. The fact is that our pulleys have the opposite effect on engine bearings. The combination of tight tolerances, quality control, perfect balance, and dramatic weight loss versus the stock pulleys reduces the stress on your engine extends the total service life you can expect from your engine. Engine bearing problems are purely associated to poor engine maintenance, use of heavier than factory recommended oils, improper engine building practices which includes poor balancing, excessively revving engines when they are cold, and owners expecting their factory oil pumps to handle engine HP outputs 2-3 times over stock HP levels.

They are, and like the 1000's of applications before them, this "balance" issue hasn't been a real world problem.

Everything on your 03 is basically the same as the 1.8T MY's before it...especially in the bolt-on world.
