Ignore the condescending answers and the ones that dont make sense, not the first time on here.
Im not aware of any pressure problems in the 350's used by the driftschools, and Ive not ever had any problems running a standard sump on trackdays or the occasional drift session either. I dont know anyone running a baffled sump on a VQ either.
First thing Id do is get a decent read on what the oil temps and pressures are, get a bluetooth OBD device and use your phone to monitor. I dont think the oil getting hot/thin would cause that much of a pressure drop, I think your oil pump might have some issues but you wont see it until you get decent measurements.
Either way, I think the issue is specific to your car and not a 350Z "thing"
Thanks, I'll try the OBD device first to get an idea of my temps & pressures, I take it oil pump issues aren't common on a 350Z then?
I apologise for anyone not 'impressed' by my attitude, however I was just not convinced by the constant baffled sump comments when I was reasonably sure that wasn't going to fix the issue. No hard feeling please, I'd rather not be hated on here!
