We need one of Pedro's wonderful You Tube videos to help with this.
Meanwhile ,try this imperfect conceptual primer.
The objective is to keep the imaginary pick up tube immersed under all driving conditions to prevent oil starvation.
.
Half fill a dish pan with water. Set it on the floor in the passenger foot well of your Boxster. Drive normally. You will loose a lot of the water. Refill it and go for a 'spirited' drive along your favorite twisties.You'll loose most of it. Yes, Virginia -water climbs walls. But you can smack it down -just put a lid(piece of plywood+weight) on top of the dish pan. You will loose nothing. If you put a piece of plywood at the bottom of the pan -it will be ineffective. Conclusion- lids work, but not if the sink to the bottom of the pan.
1. Conclusion(derived), if you fit the horizontal baffle on top of the gold spacer it will be more effective than having it at the bottom of the pan.
But Pedro proved with instruments at Sebring that Technosump 'works' even with the baffle at the very bottom of the sump .How? Because of that honking big gold spacer that increases capacity by at least 2 quarts and the gold pickup tube spacer submerges the tube in a much taller head of oil. That huge extra volume kept the pick up submerged even with 1.1 G at turn 17 - and cooled the oil also.I speculate that the horizontal baffle did very little by comparison.
2. My interest in the horizontal baffle is quite different. I wanted to slow and reduce the 'oil climbing the walls' issue. Theoretically the deeper sump(increased oil capacity) makes this issue worse because there is much more oil available for climbing now.The lid/horizontal baffle obstructs this climbing problem. Why is that a problem? Because the climbing oil could reach the height of the flailing crankshaft. If this happens it will whisk up the oil into foam.
Oh , don't forget to mop up the half gallon of water on the passengers carpet :-).BTW, You could have prevented that with a lid- but only if it was on top of the pan.
One of my first engineering jobs was operating a lab wave machine to help predict wave action in harbors.This was a fun reprise.Watch waves crash inside a harbor wall and explode vertically and ricochet back - then think of your M96 engine. That is why I bought Pedro's baffle- to calm the waves. I hope this was fun.
