Intake valves on a s/c'ed VX [pic inside]

[eternal21]

so, still 3500 for a S/C set up that has 80,000 miles?
How long does the S/C go before it needs rebuild or replacement? I know that i have seen posts here for the bearing needing service etc..
I am interested in the S/C set up for my future project.
Thanks.

I'm more of a centrifugal s/c guy, not so much roots-type blowers. But, a quick search on the 'net reveals:

Q: What about the bearings in the back of the housing? Do I need to grease these?
A: The needle bearings in the housing of an Eaton supercharger are designed to last the life of the vehicle. If you have your unit repaired by an authorized Eaton supercharger remanufacturers, they will be able to replace or grease these needle bearings for you.
