Can we read oil pressure over CAN? A big motivation to do this was to ensure better oiling for track days on 200TW tires in the future. I don't think I'll get good before/after data, but I would be nice to confirm safe PSI once it's installed.

Stock these cars only have an oil pressure switch. You'll need to add your own pressure sensor to get that data.

 

While they don't need to be replaced, they probably need to be inspected, right? I imagine they could start sticking open after really hot track days or tens of thousands of miles. I think it's pretty cool that you'll never have to buy parts again though.

 

Considering this is so common in aftermarket oil pans I'm not expecting any sticking or degradation. I tweaked each one with a pliers after the welds cooled to make sure they sit flat and swing freely. If anything they'll be more lubricated sitting in a bath of oil? I'll stick an endoscope camera through the drain hole when I change the oil the first few times.

 

Good work…….see "for sale" for my red baffled pan; any decent offer entertained………….!

 

Do these metal doors offer the same resistance to movement as the rubber ones? I have a set of brand new rubber flaps ready to go on, so I know that they aren't very stiff. But there is still some resistance to movement. If you put the pan on its side, will the metal flaps open to the same degree as the rubber ones, for example?

What I'd love to see is someone to use what the OP has done, but with a more scientific approach. Essentially, someone who tracks their Evora with the stock red pan and performs a series of oil analyses. 1-2 with the stock rubber setup and 1-2 after someone does this with the above setup. Or potentially some oil pressure analyses while on-track (both before and after the mod) like I've seen some BRZ/86 owners do to show differences in oil pressure when the car goes around turns.

The metal doors hang freely vertical to whatever angle you tilt the pan. The rubber flaps do have some resistance, but it doesn't feel like it could restrict the oil movement in any meaningful way. Since the objective here is to keep the oil near the pickup, any tendency toward migration from lateral g forces will act to close the doors and choke the flow.

It's also worth mentioning that this is going in my 2011 Evora S as an improvement to no baffling- I can't speculate that there's a performance benefit/deficit between rubber or metal doors in this pan.

Looks like Wilhelm has done a bunch more work since I last visited. Here's a bunch of oil pressure science on a 2GR that sees high g-loads regularly:

Nice work! I think my only concern with a solution like this would be is there enough clearance in the hinge to allow for thermal expansion. Wouldn't want the hinges to bind when they get hot.

Would be nice if there were an option to order a pan with these already installed.
