oh i should add however, chris (blackcoog) who i bought it from, ran it for around 100-120 miles and it worked fine but it got loud before i bought it. he suggested i get new bearings put in it but i just tried it without replacing them first..... and what may have happenned was i ran the car without a blowoff valve, along with a restrictive intercooler, and i think i surged the compressor housing..... making the bearing seal on the inside blow itself into the balls of the bearing thus ruining them. when chris talked to T.K. he said that only a few things could have made the blower bearings go out, and one of them was the BOV, which we never mentioned to him so it's not like he just chose that to blame. also he said that the ribbed belt could have been too tight (but it wasnt). if this doesnt work this time, i'm going to add onto the mount with a tab going down and extend the shaft to the other side, which will have another bearing mounted onto it, so it wil have 3 total, and almost all the bearing side pressure will be reduced to nothing. hopefully, however, i wont have to do that. the new bearings must be a larger set because he respaced the inner end of the pulley out on the charger' unit. (he's lucky it fit though, he spaced it out almost too far lol!)
