"It is still worth putting a metering orfice into the camshaft feed and either making a new bearing without the oil groove or tinning it and filling it with solder, oil will still find its way to the cam drive gears"
Charles, I presume this is for a blown engine? I think you will be aware that eliminating the oil groove when an Ulster type gear driven supercharger is loading up the system will result in rapid wear of the timing gears accompanied by an impressive scream from the mechanism at circa 3000 rpm. I speak from experience - although I was not the one who restricted the feed, I just didn't know about it......I mention this in case others with gear driven blowers are tempted.
