See those little rubber flaps hanging down? That's what makes the X51 oil pan unique, the flaps open & close during significant oil shifts. The force of the shifting oil closes the flap, and helps to keep oil in the center chamber for an extended amount of time. Since these flaps are not installed on most models, oil can rush out of the center chamber under extreme conditions and bam.......the oil pick-up tube has no oil. This piece has been very effective, and a great alternative to replacing an entire engine. Driving these cars to the extremes does have it's risks, but this should help to reduce that risk.

The X51 pan can be modified to fit most late model cars, there is an edge on the vertical bracket which has to be cut to clear the inner components (I have a templete with dimensions). A mechanic should be able to make the modifications with a grinder. It can be fitted on any Boxster, Cayman, or 1999+ Carrera (not required for Turbo, GT2, or GT3 models).

i think pedro hit the reason for oiling mods. for the 986 there are three major options:

deep sump - LN does a 1/2 quart, Mantis does a bigger one. the idea is that with more oil in the sump you need longer, more aggressive cornering to starve the oil pickup tube. the bigger the sump, the less clearance you get. some come with pickup tube extensions, some do not. requires modifying the existing windage tray windows (the flap things that hold the oil in close to the oil pickup tube). the oem windage tray has cheap plastic flaps held on by cheap plastic tabs and can break.

x-51 windage tray - designed for the 997, this tray has more robust flaps and is more 'oil tight'; that is, it will hold more oil near the pickup tube for a longer period of time. this unit is for an m97 and requires modification to fit an m96; requires major modification to work with a deep sump. don at ebs racing is now making an x-51 style windage tray specifically for the m96.

accusump - pressurised oil in a tube. when it senses oil pressure drop it adds more oil. research at canton on le engineering.

personally, i think that the ebs x-51 is for me.

ps, if you are going to r-comps you might want to think about power steering cooling also ...

Thanks for the pictures....I think we are looking what is termed baffles. I always thought the windage tray to be the flat "tray" that covers the deep sump area and shields it from air currents that could blow oil away from the pick up. The stock pan has no windage tray...as far as my understanding goes

I am actually wondering if my 3.2 already has the desirable 996 oil return swirl pots so I don't have to go out and buy them. I had thought that I would have to cut holes in the windage tray for them

This is the baffle in the 03 Boxster 2.7



I'm in the process of installing the LNEngineering pan extension.

So,

if I want to go the X51 route do I need both: the baffle AND the oil pan
or is the X51 oil pan identical to a standard oil pan?

Sorry but I don't buy it
This looks like the version I have in my 986S only with the difference that the X51 baffle is all metal while the 986 baffle is all plastic .
But my baffle also has the rubber flaps just like he X51 baffle
How do I know? I had it out when I installed the LN engineering deep sump...

There is a post of the 03 pan with LNs 1/4" baffle riser in post 18 of this thread
