So I'm out there playing with cardboard and my oil pan and I says to 
myself - If I put this baffle at an angle following the line of the hole 
in the top of the oil plan like Tony and the TR Comp manual did; 
wouldn't it want to funnel the oil "down hill" (assuming hard left turn 
side forces) backwards away from the pickup to the 1/2" relief on a hard 
left corner? Thats a good ramp and with a 1/2 to 1g force its easy to 
picture oil moving very quickly.

So - would it be better to run the baffle parallel to the oil pan 
instead of parallel to the pickup? I considered doing it in one or two 
steps to keep it close to the pickup.

The second idea would be to construct it the way Tony did but put a 
couple of 1/4 to 1/2 inch vertical baffles on the face to inhibit the 
"down hill" flow back where the screen necks down a bit and at the 
bottom just before the 1/" relief.

At the end of the baffle where the welded on tab floats above the bottom 
1/2", do you think oil is moving toward the pickup due to consumption or 
away from it due to side forces assuming you are past the apex and on it 

Am I overthinking this???
