im making the oil pan for my renesis with a 12a front cover. and im making it with a built in baffle plate.



just trying to make sure where i should leave openings on my oil pan/baffle for the renesis...same as i would an older 13b?



also...oil flows out the front cover so i should be able to remove the nut on the bottom of the front cover and plug it?

The "nut" is a plug in a oil pressure relief gallery. Remove the plug, spring and plunger and clean out the gallery, then oil and replace the plug spring and plunger. This is adjusted to open at 140 pounds to protect the "O" ring junction and the oil cooler from over-pressure during a cold start. I would leave it in.



I would make the baffle plate from 1/16" or thicker aluminum and other than the oil pickup hole and one to clear the nut, there should be only one opening as shown. This is to cure several problems. Under hard braking the entire oil supply will fill the front cover, and leave the oil pickup uncovered for a few seconds. Bad mojo. Also, a similar situation in hard cornering. At one "G" under braking, the oil surface will attain a 45 degree angle in the pan. You can brake at more than one "G".



The other problem is the oil squirted into the rotors for cooling becomes badley foamed and is then difficult to cool and is a poor lubricant. The oil moving across the flat plate has time to loose some of the foaming air before falling into the sump. This works so well you can road race with it as well as for just street use.
