Windage control is always beneficial. The plate bolted to the bototm of the engine called a "windage tray" IMO is not windage control. A screen in it's place is better, but a screen in the pan is better yet. I think the further you can get the screen away from the crank the better.

A unidirectional screen built as an integral part of the pan.

Ok here is what I have, an Olson 12 qt. pan, w/baffles, and windage plate. I see a great variance in windage plates, as well as screens. I am planning on going and adding a windage screen, just never bought one or used one, and want one thats gonna be effective.

The Stef's screen is a propritary design that Joe came up with years ago. In independent test it was worth 5HP over any other windage device when it came to the boys engines down in NC. Now they they don't run big stroke but they do run some "RRR'sss). We sell a ton of screen to others for making windage screens. Our kit is a 3 on a scale of 1 to 5 to install but it does work very well. You should be able to modify the Olson pan for this screen.

I can find this style, for the main stud mounting.



Is there more advantage to have it down in the pan? Like this....I would like to keep all the baffling intact on the pan.
