The baffle and spacer both work independent of each other and each help with pressure drop. They help, but I can't say they solve it completely under all conditions. We recently added sensors to our test car to monitor it and see how much it helps. There is also a 2 qt system that I'd expect to provide additional protection and we'll try that next if needed.

The oil pressure drops ,they are @the slowest corners @ the slowest REVs. This is what is expected at the time ,lower revs, lower oil pressure in a race. If you just had a oil pressure gauge , you might be able to pick this up, but I believe that in a race you normally do not look at gauges @ turn in. Also oil pressure senders are dampened, the data sensors can be dampened by adjusting the sampling rate, the Data dash setup controls this, much more accurate method.
Mantissport has been at the leading edge on Deep sumps. We developed this in 2006 when we build the 1St Cayman race car. Having raced a 911SC with dry sump I did'nt like the wet sump deal. So I decided we needed more oil, 2L more. Mantissport over the years has developed this into a advanced 1 pc sump, better baffling/oil dams this help direct the oil to the oil pickup. Solid bottom , more ground clearnace by 5/8". Our concept has been copied by others.In the past ,We have worked with Bodymotion group in developing Sumps, Bodymotion has their own solution, grew out of ours. Its nice.
The Mantis windage tray, prevents sloshing of oil up the sides of the block, also locates the stock baffle, above the deep sump.The oil dams in the sump direct the oil on turns to the oil pickup. We have used a local universities CFD program to locate the dams, shaker post rig testing. We have tried to provide the best solution for street/track/racing. Mantissport ,also has a custom made 944 oil pans , with dual baffles, 2L to 4L more oil capacity.

I would like to see another .7 bar if turning 7k RPM.The oil pump reliefe valve is factory set to 5 bar so the pressure will never exceede this and would be safe to redline. Or are you running looser than factory bearing clearances so the pressure will not reach max?Also I see the oil temp is 233F, where is measurement taken? what weight oil? Thanks for any detail

That said, race oil is a must when taking any of these cars on track. The factory fill won't cut it even with a 2 quart deep sump.

It is our recommendation to run the .5 quart kit with n-spec street tires. Anything stickier and that's not enough, even with the x51 style baffle. The 2 quart deep sump provides sufficient system volume and oil control for the higher sustained g-forces sticky tires, suspension, and other mods allow.

One safe option is to change the filter and top off the oil after the first race weekend and change the oil after the next event. If you plan on storing the car for any period of time, you need to put in a street oil for the required corrosion inhibitors.

I ran the FVD kit on my 996. It adds 3/4 of a quart of oil more than the X-51 pan and has improved baffles and a pick-up tube spacer. I had zero problems with this kit running rcomps, averaging 4 DE's a year. Super easy install too.

Another shout out for the FVD kit. - On JRZ Series 11 with Yoko AD08R currently at circa 20 trackdays and counting. - I run Millers 10w50 CFS Nano but change up at 6k.
Slightly off topic, has anyone retro fitted the additional X51 scavenge pump? I see LN have them for sale, Does it / how much does it, help protected against oil starvation?

There was a company that made them in europe after Porsche discontinued them, however like theirs, ours do not fit a 911 very well on both heads due to the suspension upright being too close to the pump. There is also the complexity of eliminating the tandem vacuum pump that makes installations difficult.
Once we are out of existing stock of pumps, we are discontinuing them due to lack of demand.

Being sceptical about the "rubber doors" (..they looks good on the bench, but thinking about the rubber shape when it is on his oil bath at track days session temp !!), when doing this mod, I went to Ira's good staines steel doors kit !
Note : had to modified it to fit, when using 1/2 quart extension.

I guess I'm questioning why the oil is even allowed to flow to the left and right compartments if all the action is in the middle compartment.
If oil drains to the left and right compartments, why not reroute the drains to the middle compartment and make the middle compartment much smaller so the oil has no where else to go even under high G forces.
