Thanks. Is this magazine a real publication or just on-line? Bookamillion can carry Catfancy to *** Lovers Magazine but not NPM!

Depending on who you ask, people will say that the light weight pulley will damage your bearings....same thing that happened to Mike's turbo before...

yes I did.


and yes, after eliminating most other possible causes, i really think the UR pulley was a factor in the bearings spinning. Mind you it was the 2 crank bearings closest to the pulley. Every rod bearing was fine.

Yes, this is the article that sealed the deal with me....I know NiceGuy is very adamant in his stance that the aftermarket pulleys are 100% safe, but like they say, is a $200 part with 3 or so whp worth $1000 of repairs?

agreed. and that's the Dinan tuner guy...heh, pretty reputable source if you ask me. Anyways, by taking it off and selling it, I'll be making a buck :)

the natural frequency thing is what rings with me. Perhaps the vibration frequency under the extreme load from the turbo setup is what caused the bearings to spin.....oh well.....all I know is, for my peace of mind, I'm willing to lose 3-5 hp with the pulley (I can get it back just by bumping boost 1psi or so)

Yep, most people say well everything is internally balanced so it won't hurt....well it may be balanced but there's lots of harmonics going on too.....which people don't seem to grasp. I mean, why build a stock crank with a 2piece design with a tiny rubber section if it isn't used for anything, it would be cheaper to build a single peice crank.

hmmm... Very nice article, with good pics and all, professionally done!

However, I was wondering why you said this: "Make sure the car has been sitting for at least a couple of hours (or 1, if you're in a rush)"

I was always told (and made perfect sense) that when the oil is hotter, you've suspended more "junk" in it, therefore draining it out gets more out that letting is sit, get cold, particles fall to the surfaces (not just the bottom where the drain plug is) and you've not done the best you can do. I usually have two quarts of standard oil (warmed, of course) to flush the engine with during changes.. but that's a little much. :)

My guess is to help let the engine cool down more naturally....dunno, just a guess. :confused:

Eh, it's nice and comfortable once you get used to it, like a warm glove :)
