Windage tray
 

Is the Milodon Diamond Stripper a good choice for a BBC windage tray?
Should it be mounted close, like 1/4", to the crank?

I run a 7 quart pan with 6 quarts in it but haven't used a tray since 2009. I also use a scraper even though I've been told they are a waste of time. I had already made it so it became one of those "It can't hurt" items.

I didn't have good results when i tried diamond stripper tray in SBC

Thanks Mike. I've read some positive things about the louvered trays. I went from a screen tray to no tray and didn't notice any difference at all.

Re: Windage tray
 

Whaddya mean , you "didn't have good results".
Did you dyno back to back between a tray and diamond stripper.........or make track runs and determine any variation in performance was solely due to a different tray / screen?:confused:

Re: Windage tray
 

I have been told by two very sharp, well known, engine builders to not use a tray. "Leave it out" they said, and that they always just pitch them. That getting the oil back in the pan faster is more important. I pulled the tray, did not slow down one bit. I have not used one since. That was in 2010. I think maybe you are looking in the wrong place for hp. jmho

Re: Windage tray
 

What are you doing to keep oil from getting sucked up out of the sump?
Are you using a kickout pan?

Re: Windage tray
 

One man that told me that has tested big blocks on his dyno with a clear plastic pan they built, so they could actually see what was going on in there. He said it was hard to see, lots in the air. They do not use kick outs. Most SS cars seem to use full length sumps. I just have a Moroso with kick outs, but I'm cheap.
He said about nothing sucking oil up out of the pan. This is the first I time I've heard that one.

Re: Windage tray
 

You did the right thing with the scraper, it take time to fab a good one. There is a company in Fla that makes very good ones. As far as kick outs they help on passenger side. Depth put the deepest biggest box you can. Often over look is the shape of the pick ups. Moroso has a small box style pick up that is very good, biggest thing about your pick up is to make sure it is not just sucking a hole in the pump and oil is not getting into pump.

Re: Windage tray
 

What Ed said, haven't used a windage tray in years. Was told by some very good engine builder's oil bounces off them right back to the crank.

Re: Windage tray
 

The rear cylinders move a lot of air on their way down so i think it is very important to have some type of baffle obstructing this. You can weld it to pickup tube or attach to pan but just do not want the air blast to have direct path to pickup area. just my opinion.

Re: Windage tray
 

How big would this baffle be?

Re: Windage tray
 

Oil also tries to climb up the back at launch. I have a baffle trimmed to fit the pan, bolts between the oil pump and main cap. Seems like it was from Moroso. Probably had it 5 years or so.

Re: Windage tray
 

Depends on size and shape of pan. Just take a pump with pickup and place in pan approximately in position and look at it. All you are trying to do is shield the oil at pickup area from air blast. Does not have to be pretty only needs to protect. Just use line of sight.

Re: Windage tray
 

I 've one of those for years. My car doesn't wheelstand very high but I guess it doesn't hurt to run it.

It's surprising how opinions differ on trays. The talk used to be that we had to have a tray to break up the rope of oil swirling around the crank. My pan still has the factory two piece solid pan welded in. It's pretty far from the crank. I leave it in cause I feel like it helps keep oil in the sump during shut down.

Re: Windage tray
 

The scraper is for the "rope of oil" on the crank.
I can see what Pete is talking about. I might should look into that.

Re: Windage tray
 

In my Moroso older Ultimate 2 pan it came with a diamond stripper and that's what I still use........and its easy to imagine why it would work , better than a tray. The Ultimate 2 pan has a full kickout and seriously altered sump......uses tubes through sump to pan rail.
Funny thing is , when I was talking to a "good guy" at Moroso 2 weeks ago , he wanted to sell me a newer pan , one that uses a TRAY........the pan looked much simpler than the pan I have. He told me the newer pan was worth 15 HP..........I didn't buy it . The pan he suggested is below. This pan looks much cheaper to produce than what I have now ( Ultimate 2).

I use that Moroso pan as well, with that tray tossed under a work bench.

Re: Windage tray
 

For what it's worth I called Milodon a while back and asked the difference between the screen and the tray type. Their tech preferred the tray and didn't recommend the screen.

Hamburger Pans, and I bet Stef's Pans sells pieces of expanded metal screen so you can make your own windage screen . What was interesting is this expanded metal was directional , and acted like thousands of louvers. If you sprayed water at a piece of it in the "wrong direction" the water would bounce back at you. Spray water in the "correct direction" and 99% of the water would pass right through .

Water is wrong thing to use when testing oil pans, and windage trays only thing it is good for is testing volume oil clings. In wet sump systems it is VERY HARD to get atray that works better than No tray. Worry about a well fiting scraper and large well baffled box with kick out on passengers side and a good pickup that works and doesn't suck a hole in the oil.To test pick up you must use your actual oil.

Re: Windage tray
 

I use a Moroso 21604 pan on my BBC which is very similar to the 20370 that is popular on a lot of SS big block Chevy's .
I have two versions of this pan ,one with the diamond screen and an earlier one with a louvered tray.......On the same engine with no other changes the louvered tray pan is good for a solid .070 ET and over 1 mph more. This was realized when I took the louvered pan off my spare engine at a race to replace the damaged pan on my engine in the car.
Ishihara -Johnson http://www.crank-scrapers.com/ is the company in Florida that manufacturers scrapers and trays for just about any engine....I found quite a bit of HP on my AMC Stocker using their stuff.

Re: Windage tray
 

Tom, was the louvered tray from crankscrapers or was it a Mororso? What rpm range were you in? I've been told that my 7200 rpm's aren't enough to take advantage of a scraper and probably not enough to warrant a tray of any type.

Reher-Morrison Racing Engines

New! BBC Moroso Steel Oil Pan #21049
This BBC Steel oil pan is the best we have seen in all our years of building engines.
http://rehermorrison.com/product/wet-sump-system/

On the dyno, it has shown increased horsepower and steady oil pressure throughout the entire RPM range. This BBC Steel oil pan features a built-in windage tray. It is better at controlling windage, but still fits in dragsters and door slammers. To experience the full benefits of this oil pan, it should be used with the new Moroso oil pump (#22187) and pickup. We offer a combo of the pan and the pump with the pickup. To save time and money, you can also buy the complete wet sump kit featuring this excellent oil pan. See our wet sump section for more information.

Ron It was from Moroso . ..I run that engine at 8200 rpm.
