Oil pressure drop on corner exit
Was out testing on the weekend and noticed that my oil pressure drops from normal 7ish bar pressure to 2 bar after really high g corners for a split second and then comes back to regular operating pressure.
I'm running the racing beat pan baffle, oil was not low. Should I be worried about this? Is anyone else experiencing this? Thanks, Andrew. |

Does the oil pan have a windage tray?
Love when the piston guys chime in! :D Obviously, even with the baffle plate you're uncovering the pickup. Only way to explain pressure drop that only happens during cornering. Accusump may help but it's a bandaid IMO. Got specifics on the car? Dual purpose, track day, purpose built to a rule set? The baffle plate usually works well enough for most racing applications. The best solution would be a dry sump, but it's big money to throw at dual purpose car and not legal for many racing classes. |

I'm going to try over filling the oil a touch at the next event and see what happens, other than that I'm going to have to do something with the oil pickup/pan. Andrew. |
Over filling by a half quart or so is pretty standard. As long as you're not sloshing it out the PCV holes at the top of the fill neck you'll be ok.

I think a trap door setup or if possible a swinging pickup would work great. As for the accusump. I'd run it. Bandaid or not it will save your engine.

I think I'm going to drop the pan this week and fabricate a trap door baffle system around the oil pickup in the pan. Similar to this:

Wait, an oil pan battle aka windage tray CAN be installed on a rotary engine??? Did you see that Ludwig? :)
