Oil Pump & Camshaft Gear Oiling Modification

Where? What VW application?
And on your want for a HV pump... would putting the Hemi HP (hi pressure) somehow pull more "draw" and give you the extra volume you're wanting? The effect of HP would be diminished with all of your extra "leaks" with the full grooved bearings and this nozzle for the oil pump gear.

All the Hemi spring does is increase pressure. It takes a wider pump rotor to increase volume.....which essentially what you have with an aftermarket pump. Their rotor is 7/8 wide, from the stock 5/8. The true HV pump is 1" wide. But as I've been saying, it does not appear that a 6 bolt HV pump was ever made.
