Windage Tray: necessary?
You can also drive a car with your feet if you wan to.
Doesn't make it a good idea.
He supplied an "A" engine AND requested a VERY DEEP "windowed" Oil Pan be installed allowing a "view" of the internal oil windage with a running engine.
A lot was learned with ANOTHER MYTH proved incorrect.
The engine oil is NOT "thrown" into the Oil Pan, in fact the opposite occurs.
The oil remains attached to the crankshaft, rods, rotating items such as you find in a Tornado.
I called the effect a Salt Water Taffy.
...
As I said previously, my super high end circle track sbc’s made more power without the trays. Dyno proven results, but a different engine platform.
It's definitely a good idea to run a windage tray. Why not?
A crank scraper is even more effective at removing oil from the rotating assembly. In some cases we run a crank scraper and no windage tray. In the C5 batwing pan, for example, we run a scraper but our windage tray won't clear the pan. Because the pan is so shallow and close to the rotating assembly already, with a crank scraper in place you don't really need a tray as the covered upper section of the oil pan basically acts as a windage tray.
We shared some Oil Pan Tech when I designed my LS Oil Pan.
He stated that he was able to report "tech" about an engine test with NO OIL PAN FITTED.
This engine was benched AND a 1/2 cut open 55 gal fuel drum was placed under the operating engine.
The Back/Back dyno reported a HP increase when NO Pan was fitted.
Call Dave for the full report or Engines.

The Best V8 Stories One Small Block at Time
It's not so much about the crank HITTING the oil, but more about WHIPPING up the oil below the crank, hence the need for windage trays.
SURE, I baited/hooked MANY here with the "panless" engine report, a TRUE REPORT !
This test was a REQUIRED test to PROVE to Dick Moroso that HIS Oil Pan/Scraper design was NOT PERFECT.
MANY here will spend 3K dollars on heads/cams/etc. for 20 EXTRA HP, then NO Money on a good windage/scraper tray that would cost LESS THAN $100.00 providing the SAME increase in HP.

Windage trays are like other performance parts, for some situations it's a must and for others it's unnecessary. It's up to the builder to figure out exactly what's needed based on how the engine is going to be used. The recommendations for a scca road track vette aren't the same recommendations as for a suburban that only drives 5 miles a week to the fishing hole.

THUS, great savings for GM in Emission TAXES
THUS THOSE "bean" counter's RULE, thanks AGAIN.
