Wow that sounds like a great price. If this shaft and upgraded bearings solve the problem you may see more superchargers selling. I for one wouldnt mind getting one if it was a solid set-up. Hopefully this helps.

No update yet, snow storm in Chicago today and I didn't get home until after the shop was closed. Will see what i can find out asap.

any word on the shafts yet? Anyone do an inspection on them? check them for truness?

First prototype i got on monday was slightly off. Adjustments have been made and again because of New Year, I have to wait until Friday. Also got a hold of some bearings that are rated at 13500rpm. I have talked with every major bearing manufacturer in the USA and this type of Koyo bearing is the only one that will go up to 13500 without oil. So the bearings vortech supplied are 8000rpm no matter what anyone says, that type of bearing isn't made anywhere in the world above 8000rpm. The new bearings i found have smaller balls and less friction and are WAY cheaper than ceramic. They will be included, pressed on, with the shaft when i have some available for sale.

Very nice, still watching.

05-RS1 01-01-2009 06:24 AM

been following this thread. glad to see progress is being made. so why is it beneficial to get the shaft assembly replaced?

PeaNut 01-01-2009 06:38 AM

watching, hope this pans out well.

The stock shaft sucks, but the main benefit is that many people who have had the bearings crap out also have a damanged shaft that will keep eating bearings unless its replaced.

13.5k seems low. and the vortechs have to be higher than 8k stock. they'd be burning up on the first crank.
and i have seen bearing speed specs higher than 13.5, although they were hybrid ceramic.

Hybrid ceramic can go over 13.5k yes. But the highest i can find are 13.5 in a metal shielded bearing (actually the highest that is made by any bearing manufacturer in the US in non ceramic!). All the places I talked to cross reference the skf oem bearing to a bearing that is not rated for the right speed. 13.5k is the highest rpm bearing you can buy that isn't ceramic, and ceramic is so much more expensive that its not worth the trouble. You would be better off replacing the bearings every year. Which i still will probably end up doing. The bearings I found are $35 a piece, not too bad. I'll have more info later today or tomorrow.

but again...13.5k max seems low. it will spin much more than this.

Putting the crank pulley size and s/c pulley size into the formula at redline 6300rpm with 12psi pulley i get just under 12500rpm.
