School me on new gen hemis

General opinion amongst the 9 sec crowd on Modern Mopar forum is that if you are going to spin a 6.1 at or above 7000 rpm regularly - then an extra capacity pan or accusump is really a must.

I researched this and posted this on Modern Mopar Forum based on a conversation with Stanton motors:

Here's what they said:
-The original problem with the drag pak motor is they were not built to be raced as delivered. Page 12 says the motor needs to be taken apart and built to customer spec (oh yeah, he quoted it to me). Also, he commented that the turnover on drag pak racers was like every 6 months they had a new group of racers replacing the old group.
-The stock 6.1 crank being cross drilled is fine, that is not the problem.
-The problem is starving the motor of oil
-In the drag pak cars, you have to run 11.5 quarts of oil total between the drag pak pan and an accusump (pan = 8 quarts, accusump = 3 quarts =overfill the pan). He mentioned if you're running without an accusump, you better up the pan capacity
-They have multiple drag pak cars running 8200-8600 rpm with stock 6.1 cranks, and he rattled off John?, John McCloud?, ATI?, Jason Batey?, and Roy Johnsons Dad (?) (5.7). Mentioned trouble free for ~2+ years

Quextion is - does the 310003 wings clear your headers - unfo on mine they wont

I spoke with TTI. They indicated it would fit based on pictures (didn't have one to check with).

I believe (not 100% confirmed because the Milodon website is a little unclear) The stock capacity of the 5.7 and 6.1 motors is 7 quarts six in the pan + 1 in the filter. The Milodon oil pan PN 31000 has a 6 quart capacity, whether that is 6 in the pan +1 in the filter or 5 in the pan +1 in the filter is unclear.

Milodon also sells an oil pan PN 31003 that has wings that Appears to increase the capacity by about a 1-2 quarts. Milodon doesn't even list an oil capacity. GRRR. So this one could be 6+1, 7+1 or even 8+1.

As for putting 10 qts in your car upon start up. That seems like a lot, but who am I to argue. With a remote oil filter and perhaps oil cooler ten quarts is probably not unrealistic. From your description it sounds like the Milodon pan PN 31000 has a capacity of at least six quarts meaning 6+1. Which would confirm your statement that the Milodon Pan is close to the factory size.

One thing to keep in mind, particularly for those who plan to run a flying mile or road race the car, is that oil coolers, lines and remote filters DO NOT INCREASE the capacity of your oil system.

Be clear that extra filters and/or coolers do not add any oil to the engine's sump capacity. What oil is added to fill them always remains in that device and is not an additional supply for the engine's higher RPM needs that is the job of the larger sumps.

So I would agree with Rat Patrol that those planning on spinning the snot out of their motor should invest in a higher capacity pan. I'd get at least the 31003 Pan.

I run the 31000 pan on mine with a 3 quart accusump. I haven't had any issues road racing or shifting at 7000+ (did spend ~10 seconds at 7000+ in 4th at the mile). You can put more than 6 quarts in the 31000 without it interfering with the crank, but YMMV. I used to run 7 quarts in the pan and whatever the accusump holds, but I've lowered it since then (maybe 6-6.5 in pan).

When I spoke with Milodon, they indicated the new roadrace pan was 7 quart capacity, vs 6 quart capacity of the 31000. FYI- The 31003 is actually 1/2" shorter than the 31000. The pickups are different as well.
