The 2 areas for starting a screwdriver or other pry tool for removal.

-10 AN turbo drain adapters (optional).

Feel free to comment likes or dislikes of these changes.

One more feature request to evaluate:

Fabricate the top horizontal plate baffle to overhang the outer edges of the vertical baffles in the pan by about 0.75" to help prevent oil from rolling over the top of the vertical baffles in high G turns.

I had considered extending out a little bit for the purpose of promoting the outside oil to use the baffles rather than the top, due to wondering if this might work better for the oil pickup.

What if instead of extending the horizontal plate out to the sides more, we had it take a 90 degree turn upward for that 0.75"? Than perhaps some small openings at the base of it to allow oil in the middle against this new vertical wall a place to pass-through to underneath the plate?

What are your thoughts on that?

For those that are nervousness. I've tracked my AM pan for over a year now. NO PROBLEMS! The pan where it bolts against the block is flat. No groove. I used black rtv that is O2 safe. NO leaks around the pan. As for questions about the baffles. Don't worry. phunk's pan is an up-dated version of the AM Perf. So it will perform.

If I didn't have the AM Perf pan. I would be up phunk's asss about one too.

I am guessing that there may be as much as 2 quarts of oil trapped in the upper part of the engine at 7500 rpm. That makes the level of oil in the pan lower than when the engine is at low rpm. I haven’t seen inside a VQ37, but if it doesn’t have an oil scraper pan under the crankshaft, the vertical baffle with the small openings you suggested may be above the surface of the oil and might actually help recover some of the oil spinning with the crankshaft. So maybe the vertical portion of the baffle should be taller than .75” and maybe 1.25”. But if we are catching windage from the spinning crank, the vertical baffle may need support. You’ve been inside the engine. Does this concept make sense?

Have you had your oil pan off and looked up at the crank? You would have to remove the lower part of the motor to install a crank scraper. The lower part of the motor and oil pan is designed like a deep sump pan to begin with. With the sump in the front part of the motor.
