i second the "hmmmmm" (or third it!)

the three bolts secure the blower. period. tow bolts will allow some oscillation under load, but the third bolt now triangulates the load (the triangle is the strongest geometrical shape) and will keep the blower sound.....

IMO, of course.....

anyway....

hmmmmmm..... backatcha!

Sorry all. I didn't mean for the "hmmm" to sound that I was saying that was the cause of the problem. It was more of a "Hmmm...I wouldn't have done it that way."

the 4th bolt is not related to this issue. I had the same problem occur on my Z and everything was mounted to spec. fortunately, mine did not incur the level of damage dollar's did.

so leaving the 4th bolt off has no bearing on pulley alignment, you may think its on snug, but who really knows if theres any misalignment during hard WOT runs?

I don't think my pulley issues has anything to do with the blower flexing or vibrating on WOT runs. The rubber belt should allow enough flex to counter this problem. I think my pulley problems is caused by compressor surge from the BOV being too tight. Cause the belt wants to spin the compressor one direction while the surge causes the compressor to want to spin the other direction.

The fluttering sound is the worst compressor surge possible. Suppose you let off the gas and engine brake, the vortech bov should make a constant "shhhhhhhh" noise. If yours makes a fluttering sound then you have very bad compressor surge. If you only hear the fluttering noise when shifting, you're bov is still too tight even though it sounds awesome. If your bov makes a "ke pisshhh" sound when shifting, this is a very SLIGHT compressor surge. If your bov just makes a "pshhhhh" sound then there is no compressor surge.
