Got the blower case back from the blasters so set about doing some modifications to it, First the support bar in the intake side was removed, its not needed now its not hanging on its side anymore, once out the edges were milled to clean it all up.










Heres a pic of a stock scavenge pump setup incase you have not seen one.








My small mill doesnt have enough throw to flycut the intake angle out so popped into my mate Brians shop and used his. While I was there the intake throats were bored out from 1.250" to 1.500", the bottom plate of the plenum was bolted in place and both bored together to keep the throats aligned.












Correcting the intake angle meant losing the rear stud hole, we spotted it through first and retapped, Will weld a bung in here at some point.
The dividers in the throats will be ground to a knife edge so as not to disturb the flow.








The bracket bosses cast into the intake no longer serve a purpose so cut them off and blended them smooth, this uncoved a hole so it got welded shut,












Here the plenum sides are tacked in place, the tricky to get at bolts are now much easier to get at as they go through columns.
Couldn't do any finish welding as my 200amp isn't gonna be big enough as the aluminium is 1/2" thick, gonna need a fair bit of preheat on it.
