IIRC the Repco-Brabham won the WDC and WCC in 66 and 67 with a wet sump having a heavy sliding baffle plateandylaurence wrote: ...... I know a few people running a rotating oil pickup in a wet sump that rotates forwards under braking, backwards under acceleration, etc. That's normally combined with a baffle plate. Some people also add in an Accusump. The full-house option is a dry sump kit and that's what I've got fitted. I've got a tank of about 10-12cm diameter and 40-50cm tall. No oil surge at all at 1.8G. Hopefully, I can say "no surge at 2G" next year...
then the Cosworth DFV changed F1 oil systems, scavenging atmospheric air to entrain scavenge oil, so needing seperators
presumably current race oil resists foaming much better
btw does the car really need to be dynamically symmetric in any way ?
in the past offsets layouts were not rare, even on road circuits
there may be overall performance benefits eg on the majority left bends from suitable and convenient asymmetry, even of lateral cg
the straightline braking case would need some design thought of course
