My pleasure,
here are a few pics of the typical porting that you can identify on the G40.
First is lightly ported, note the thicker vane at oil supply intake, this vane is typical of all the vanes if
no porting has taken lpace, though this charger has been lightly ported ion the other vanes,
Inside,
and Out
This charger once again still shows the thicket oil feed vane, but the other vanes have been pretty much maxed out as far as material removal go's.
Once again inside
and Out
Beside this porting on the outlet vanes, chargers should be ported on the scoll pass through port/vanes, this is a lot more tricky due to the restricted access, and if too much material is removed then the scroll can be more prone to failure, plus the balance shaft will need to be tweeked to avoid vibration issues.
