The car is a gravel stage rally car. It happens turning both left and right during stages, which makes sense as the oil pickup is in the centre of the sump. I don't get much of a chance to look at the oil pressure gauge during corners, but it will drop from around 350kPa to 100 at the exit, before immediately rising again.
Cornering forces are actually reasonably high, despite being on unsealed roads, and on sweeping corners can be sustained for some time. In terms of traction, on a swept road (one where the preceeding cars have cleaned off the loose gravel to leave a solid base) it can be close to driving on tarmac. Tyre squeal is not uncommon!
If I do baffle the sump, I will take it out of the car. Welding upside-down sucks, especially when there is a pretty good chance the oil coating left on the inside of the sump pan will ignite...... ;-)
