On a procharger or any snail style blower, what are you doing about your idler pulley?

I keep breaking them with bearings rated to 18,000 RPM. I hear I need 25,000 RPM bearings, but they do not exist for my application.

What is your solution? Besides not driving the car.

call a bearing place. motion industries or detroit ball bearing. there are different classes of bearings. a higher rpm bearing doesn't necessarily mean it is stronger.

give the the od, id, width, and tell them what you are using now and the problem your having

You keep breaking the idler between the blower and alternator?

The idler pulley on a vortech/procharger setup spin at the same rate no matter how many psi you are running, however there may be more tension(stress) on the pulley/bearing depending on the tensioner setup. The belt only moves as fast as the crank pulley turns.

Yes that's the one.

The only solution I can think of is to keep changing the bearings every other oil change or every oil change. They are only $2.97 on-line. Not a bad price to pay to keep the machine going, but still there has to be a long term solution.

Yes that's the one.

Dom.....contact Doug at BilletFlow!!

He made me some super idlers that last as long as the blower does......about 60K miles!!:beer: My PC idlers wallowed out in about 5K-10K miles!!:argue:

He made me a steel prototype first that I ran for 10K miles and finally made 100 in ceramic coated aluminum in black.....very nice stuff but PC was not interested as they have a contract with their current supplier!!:shake:

Great! Jack, what did those run you? The whole pulley correct? All I need are the spacers?

Yep....all you need is the PC spacers Dom!!

Same price as the PC junk......$60.00 each plus shipping last time I got one several years back!!:beer:

Good Luck!!

Great. I hope he will sell me just the bearings and one complete pulley. I have a spare PC pulley with junk bearings. I would love to swap them out as my spare.

As I recall the PC pulley uses 2 bearings, a spacer and snap ring to hold the junk in the pulley!! :shake:

Doug's bearings are pressed in back to back with screws to lock them permanently!!:beer:

He'll probably do that.....give him a call!!

Great. One complete pulley, one set of bearings and.... err... two sets of spacers from Failcharger.

The call will have to wait for a week or two though. :alone:
