Do you have any A,B,A test results on using it compare to no tray at the track or on a engine or chassis dyno?
The reason I'm asking is I was told way back when (before 1988) by one of the fastest NHRA Stock SB Class racers in the country that the stock type windage tray costs power, he thought due to it making the oil bounce back up into the oil cloud surrounding the rotating assembly and not allowing the oil to drain back into the pan, especially above 3500 RPM
