Oil pan

Would a 9qt oil pan be enough for a 540ci n/a motor or would the 12qt be better? Pros/cons

Depth on both?  Do they have a kickout on the even bank side for windage?

I think the kickouts like pictured below are better than the inverted T style.

I highly recommend reading the following:

https://rehermorrison.com/tech-talk-74-the-oil-pan-paradox-power-or-reliability/

The Mopar Chassis book has some great information also.

I can't find it now, but David Reher discussed moving the oil sump far away from the crankshaft.

I have looked at many hulls, rail kits, and oil pans.  I have concerns regarding the volume of oil in the pan.  It is very easy to fill the pan so that the oil level is above the windage tray.  If you can run the bigger pan with less oil, it's beneficial to windage.

While I was at B1 Racing, we received many engines, right off the dyno.  The engine builder told us that, "the amount of oil in it now made the most power."  I strongly believe that the angle the engine is at in a boat will have a totally different dynamic effect compared to an engine dyno that is mounted level.  Again, I feel reducing the amount of oil is necessary.

I would definitely check the fitment of the pan in the hull before installing it.  A tunnel boat doesn't tolerate wide kickouts.

I run a similar pan to what Flusher posted on my 598 and it works great. Even hard turns the oil PSI stays up, I would recommend the bigger pan too, if it fits

Do you have a pic of the inside?  What oil pick up you use?

Itís 12 quarts, itís in a flat bottom so there is plenty of clearance. The pan is actually a custom built pan for circle boats designed by Gordon Jennings. It has trap doors in it to keep the oil around the pickup while making hard left turns. The pick up is also custom made. It works great, itís just a bitch to get on and off

The picture I posted was the first Google image I found.  I lost all my pictures when my SD card died.
