So much for the pulley "saver" kit...
From normal acceleration I hear a weird noise, then my display turns into a Christmas tree with lights everywhere, error messages, No power steering, etc.
I pull over to find this under my hood...





The belt was shredded, pulley in two pieces, and a hole in my coolant hose...
I immediately email Rob @ Needswings, and he called me seriously 5 minutes later! (on a sunday). I explained what happened, he was just as stunned as I. He was extremely helpful and sent out new parts asap.
Anyways, I thought this was supposed to help save the pullies not have them crack in half!
and glad to hear about Rob. He is unbelievable helpful and always available. Great guy
I just installed a 185 and the PSK a couple months ago. Do you think torquing had anything to do with the failure? The bolts kinda just tighten over the bearings if you know what I mean.....From normal acceleration I hear a weird noise, then my display turns into a Christmas tree with lights everywhere, error messages, No power steering, etc.

Luckily nothing else got damaged. Just the pulley, belt and coolant hose.
Bearing did NOT seize, which is weird. The bearing still spins good and wasnt on too tight to where it wouldnt spin either. The bearing and pulley is from Needswings, not sure of their supplier.
yeah I'd have to agree!

OK, I don't want to beat that drum, BUT this is the very reason why I use the Code 3 pulley (and maybe ECs new SC pulley soon) on the C32. I know that the PSK is a good kit and that Needswings will back it, BUT the fact is, the darned 185 just overdrives everything.................

I know the PSK is supposed to alleviate the problems with the 185 "overdriving" the accessories etc....................
Does anybody here know what a tune would make with just an intake on the car? Would it be worth it at all if I dont have major mods?
I'm still going to run my 185 + PSK, but if i start running into bad pullies and killing alts and PS pumps i'll look elsewhere for an alternative.
It all comes with the territory though.. you gotta pay to play.
The PSK addresses other kits' approaches with the aftermarket idler nearest the waterpump pulley being overdriven to the point of potential bearing failure, as well as achieving a marginal improvement in belt-wrap on the S/C pulley. From what I gather, the PSK has no affect on the drive speeds of the accessories (alternator, A/C, etc.).

i'm not quite sure what the pulley saver does still...does it slow down the speed of the pulley? I hope it does because if it only lengthen the belt it really doesn't do much.
If I read about this happening many times, like with CPS or Bad Seat modules i could see concern, but once? NOT.
And my idler pulley went bad and sheared off my water pump pulley back when it was bone stock, so no matter what mods you do or don't have, it is likely to happen unless you're proactive and aware.
