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.

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.

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:

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

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.

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.

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.

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.
