Hi rpm oil starvation

Spooler

I'm in depending on price.

Rusty

It's going to be cheaper then the AM Perf. pan. If you can find one.

is the design of this pan going to support 9k?

I'll guarantee the pan to hold up to 9000rpm no problem... But I can't promise it will hold up to the other bits of engine that will be thrown through it when you get there

Your pan looks great!

Your oil pan project had caused me to pay attention to the motions of my car and try to visualize what happens to the oil in the pan when on real world driving surfaces. One condition has kept me afraid of holding rpm in the 4500 – 7500 rpm range while cornering aggressively. That is an undulating surface. In the extreme violent pitching of the car would require a dry sump system. From the pictures of your pan I see how the extra depth and flaps control lateral oil movement and keep the pick up submerged. That works on smooth surfaces. My concern is how much vertical - g will this design tolerate and still prevent oil starvation. Could some sort of a grate be positioned over the top of the pan to keep oil from splashing up away from the pickup when the car is pitching in a turn?

The extra capacity through depth with extended pickup will reduce oil starvation in any direction. We can extend the top plate out to the sides more but we have to make sure that what we are doing is not going to promote oil starvation more than reduce it. I am open to any suggestions for additional baffling but I also lean towards a somewhat conservative baffling approach. The more baffling we add, the more thought has to go into the system to ensure that we arent going to make things worse.

If you wanted to draw something along the lines of what you are suggesting we can look at it an evaluate it. I will make it however you guys want it, I just have to make them all almost the same for manufacturing to be cost effective.

I didn't realize your pan had a top plate (baffle). That is why I suggested a grate to control oil splashing upward. Can you post a picture of the top plate?

Here is a drawing (crude) of my idea to include a grate like structure on your baffle. The idea is to make it easier for oil to flow down into the pickup area than it is for oil to splash up away from the pickup. The grate ribs would have a triangular cross section to accomplish this one way tendency. The openings in the grate should have corner radii to make the baffle structurally sound.

Grating could be added like that, but the draft on the walls of the openings might not be an option... I dont think the laser cutters can cut at angles like that but maybe they easily can. I can ask my friend who runs that. If you want a custom top baffle plate like that, its really nothing for me - it would take me 10 minutes to draw that in CAD and I could order it with the rest of the other ones. If you convinced everyone into your design, I could just make them all like that.

The pin is pivoting in the pan since it is the least resistance. Even reamed out which is a good idea, there will be greater contact area between the pin and flapper than there will be in the .25" of contact on either end. The flappers are very easy to move in the prototype. Just lightly blowing on them pushes them open.
