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.

Material ordered today.

I have sent a couple PayPal requests. Please PM your PayPal address or if you wish to use CC for the deposit let me know via PM the best time to contact you.

Thanks!

BTW I will be presenting some potential baffle updates and let you guys decide which layout you prefer

Charles, you are on point

I wish I could commit to one of these functional pieces of art. If I could, I would buy one now and display it in my garage until I found the need to install it

I would like to buy one of your pans for my Z,

I like your suggestion of a top baffle that that has a .75” lip at 90 degrees up to aid in lateral control without hindering oil return from the back of the pan.

However, I am concerned that there needs to be more baffling to reduce oil splashing up away from the pickup when the car is pitching on uneven roads. I would like to see a top baffle that also includes a down pointing 0.5” lip inside the chamber around the pickup to trap oil if it tries to splash upward. I don’t think this would hinder oil from reaching the pickup from the back of the pan or from the sides through the trap doors.

Will you make this baffle design available on this initial production run?

phunk · 06-03-2015, 08:13 PM

The standard baffle already shown will be available for certain. I am going to play with some alternate designs and if I come up with something still manufacturable in sheet metal using lasers and bending, I will present them and any slight cost differences they may have if any.

For any more complex billet top baffle plates, I am not currently working on anything for that.

PRESALE LIST moved to first post to make it easy for everyone to see and watch for updates.

I will work on some potential baffle updates for you guys over the next evening or two and post images. Please stay tuned for that.
