Quite a bit of CAD going on this week, in hopes of getting the dry sump system all fleshed out and ready to machine.
Picture quality is horrendous because I was doing the good old "Send a buddy photos of the computer screen from the phone while working on it.", and didn't actually use screen capture/printscreen on the laptop.
This was the top plate of the sump after the feed line for the factory oil pump in the engine keg was laid out.
Oil flows in at the bottom left side, and is pulled through to what used to be the oil pickup tube flange.
A very rough quick draw of the scavenge pickup channels. They're represented by the series of blocky green rectangles.
The view as depicted is looking up at the bottom of the engine from the back of the vehicle.
Think rolling under it on a creeper with the drivers side and transmission to your right.
The pickup channels will have their slits at the bottom "L" feet so they catch oil when under acceleration.
One scavenge channel "done enough" for the time being. One more to go, and some cleanup work
This is a top-down view looking "into" the lower plate.
The main feed channel will have one continuous o-ring groove milled into the divider wall, and get some 518 anaerobic sealer when the time comes.
Some mockups of the scavenge pump mounting to the plate stack.
The plan is to bolt the pump rigid to the sump plate, and seal it with o-rings.
On that note, I may end up using trimmed down VTEC gaskets to seal the pump down, since they have catch screens already molded in and are cheap-ish.
To do the bolt-on will require either machining the pump housings flat and removing the lower ftting protrusion, or making new housings.
I snapped up another three stage Weaver pump off eBay yesterday to be the test subject for modifications. It's got an internally routed single scavenge outlet, instead of the twin outlets on my existing pump. It also came with a pulley and hub as an added bonus.
I'm still on the fence as far as what to do with the third stage pressure section on these pumps. I could use it as circulation/cooler flow pump, cut it off and make it a scavenge only pump, or maybe even machine a lip seal carrier and use it as a transmission spray-oiler pump.
I also snagged a used A/C compressor and line set so I can check fit on the dry sump pump and start in on designing the tensioner bracket to loop the serpentine belt around it.
Since I'm still using the factory chain driven oil pump for pressure, I can get away with running the scavenge pump off the A/C serpentine belt.
A/C compressor has to still fit, because I like creature comforts, and it will end up being part of the charge cooling system as well.
