How do you know you don’t have one? Doesn’t sound like the kind of thing Scotty G would forget to install.
If you need it,I'll take $20.00 plus shipping.A small small PO cardboard box will cost $8.00 to ship.Bruno.
In all the pictures I have from my engine build, I don't see the tray either. I do have an SRE pan though.
I punch holes in them so oil doesn't collect, I'm sure Buick felt the need for a viable reason,but my last 3 engines haven't had one
Gonna be a lotta opinions on this subject. The windage tray has a couple important tasks. At higher RPM it helps keep the oil that's being flung from the rotating assembly as well as the air/wind that's created, from uncovering the oil pickup. At the same time it helps prevent that oil/wind storm from aerating the oil in the sump, ... which in turn can lead to oil pressure loss at bearings as well as higher bearing temperatures. It also helps keep the oil in the sump from being whipped back up to the rotating assembly resulting in a measurable horsepower loss. Since I'm running wet sump systems on all my engines, I as of lately turned into an oil control fanatic. I added a louvered baffle that I found through Champ Pans into my Stef's pan and plan to incorporate the same style louvered tray/baffle into my new SRE Girdle Pan. As for the original post, .... I believe that for a stock to moderate build not regularly seeing above 5500RPM the OEM baffle is fine, but I personally would not run without one if I had the choice. Larry
I'm not sure if a big windage tray is better than none. Because the shield is mounted on the mains and is therefore very close to the crankshaft. At high speeds, the drops from the rotating crankshaft collide at high speed with the sheet metal and are thrown back. In addition, the shield has many small holes and the oil drips back through these holes, with each drop air is trapped.
I dont have one and run a dri sump with a TA deep pan. I think in a race only application there should be no issue
I have motors with and without, haven't really noticed any difference, then again I don't spin them over 6500rpm,maybe at 7000rpm its necessary I don't know.
I worked on Dan Horan's Nostalgia Top Fuel dragster. They turn those things in excess of 8000rpm. Pan, heads, everything comes apart after every pass. The shallow pan did have a slotted windage tray. Everything had to be taken apart and cleaned because the fuel mixed with the oil. They ran over 125psi of oil pressure. I went to Daily's oil pumps (Daily Engineering) and talked to Bill for quite a while. He said everyone gives up horsepower running way too much pressure. We always say "its better safe than sorry". Not if you want to win. I learned that day that there is a balance to everything. I remember from my Kenne-Bell days, "Don't out trick yourself ". Jim Bell had a way of saying the right thing at the right time. Those were the fun days, working on a top fuel car ..not so much! Everyone could use a windage tray, just don't ask grandma next door, she probably doesn't have a clue! (get the point?)
Rick, I used the CP15007 which is a BBC Dry Sump Application. This fit the bill perfectly for my External Pick-Up style pan modifications. http://www.champpans.com/products/p/cp15007/ Larry
Are you using a belt driven external oil pump like I am? Here is mine.. I have a similar windage setup, the pickup is not used I also suck the oil out of the side of a custom pan:
Sean, I'm not using an external oil pump. The External Pickup system incorporates a suction line/hose that is routed outside or "External" of the engine block. It runs from the oil pan sump to a specially designed oil pump cover. That system eliminates multiple 90* turns and also allows for a larger pickup/suction I.D. Larry
