What size oil tank should I use on a 572 that will see lots on lake use?

Who makes the best pan?

Thanks,

Chris

I am very pleased with my Armando's pan, he's been building pans forever. Many members have them, good selection of options, he's located in Texas.

I think a 2.5-3 gal would be the minimum I would run. Perfer 5 gal.
Pans, Stefs, Aviaid, Armando, Johnstone's Billet Fabrication, and Moroso all make pretty decent pans.
I don't lose a lot of sleep over the pan, ITS THE TANK THAT IS IMPORTANT!!!! I prefer Patterson and Stefs tanks over the others.

The bigger the tank, the less you have to change the oil. Also, the dry sump system sucks a lot of air in with the oil, runs it thru the pump before dump it in the tank which isn't as good at separating it as people think. Without an air separation segment in the pump, you are totally dependent on the tank to handle it for you. The more oil in the tank, the less air you tend to pull off the bottom to send back to the engine,

I did talk to Armando good price and short lead time but I've heard that lately his quality has been lacking a little bit. Not sure if that's true because all I've ever heard is good things about Armando.

Thats kinda what I was thinking around three gallons. I get that bigger is better but I just can't see putting a huge oil tank in my boat. I've seen some 5 gallon tanks that were just huge. I like the looks of the baffles in the Peterson tank.

i forgot to say that I will be running E85 or methanol so I would think that I should change the oil more often anyway.

I haven't heard anything about the decline in quality of Armando's pans.
The tank I was referring to is a PATTERSON, not PETERSON. I have never seen a Peterson in person, but I have heard they are pretty nice.
Patterson has ONE product, dry sump tanks.

A tank heater will help drive off some of the alky from the tank each time you are done using the boat. How often depends on your tuneup. But yes, you will need to change it more often than gasoline.

I'll look into the Patterson tanks.

if I was to run a three gallon tank how much oil would really be in the tank? I would think that the lines would hold a quart, the filter will hold a quart depending on what filter or filters. But obviously the tank wouldn't be full to the top.

In a three gallon tank I would think you could run 8 quarts plus whatever is in the filter and lines. Is that even close to correct??

What kind of HP increase might a 572 see with a dry sump spinning 6K? And then again for a vacuum pump?
Tim, the same guy that built your engine built mine. He told me that you will see minimal gains from a dry sump over a GOOD wet sump pan and vacuum pump. But if you were starting from scratch it seems like the price is not much more for the dry sump system. The dry sump system offers superior oiling and according to some increased bearing life. I guess its like anything else.........the wet sump will perform well if you set it up right.

I talked to billet specialties and they have a really nice wet sump two piece pan for $1250.00 it is designed to be used with the Titan pump for another $514.00 but if you buy them both they will give you $100.00 off for a total of $1664.00 add to that a vaccum pump and all of the drive accessories and (close to $1000.00) and you are up to $2664.00..........At that point I decided to go with a dry sump.

I'm sure that there are cheaper ways to go but why would a guy spend all the money on an engine and skimp on the oiling system? Right now I have nothing no pan, oil pump, or vaccum pump and the boat will only have two seats so I have the room for the tank and I'm starting from scratch so this is the way I decided to go.

The longer the stroke the more windage becomes an issue so if you have a wet sump system and it is working good for you, you will see a H.P. increase just by adding the vaccum pump. Depending on what rings you have the increase could be pretty big.

How much H.P. did you make with your 572?

850hp @5900rpm It It is good for now but someday I would like to up the peakrpm a bit with a new camshaft and possibly add a vacuum pump, dry sump, timing belt vs chain ormaybe even shaft rockers. But for now things are running good so I will just enjoy. What did you have built?

572c.i. Dart big M, 14.5:1 CP pistons, Eagle crank and Scat rods with AFR 335 cnc heads. I had him do a little work to the heads they flow pretty good. Bullet cam shooting for Max HP @ 6500 T&D's. I was planning on running E85 but I might just go Alky, not sure yet. Dart tunnel ram Fast XFI 2.0 EFI. Joey did the machine work and I need to put it together but im still collecting parts.

Sounds like you have a nice stout piece there. I never got to see you run before you moved South. When I dyno mine I'll let you know how it does as far as RPM @ max HP. I sure hope it spins a little more than yours or i'll be looking for a different impeller.

Sounds a lot like mine but I have 355 dart heads and a single 4bbl carb. I had to go from a B to an A+ impellor. I like the E85. Good luck with your build
