I don't think Vortechs use ceramic bearings.You can see the oil feed going to the charger(black pipe) in the picture. Mines 2.9, vortech v1, stock compression, maf before the charger, 6.5 psi no intercooler. You might be running a bit rich as the maf is after the charger - air is constantly be registered by the maf's filament and the ecu is chucking more fuel in even when your not on the throttle.
