Quantrill, if you send me a PM we can work together on these oil pressure problems.
I'm using a 2009 ZX10R in an SCCA road race car and have been working on baffling in the stock pan. The data acquisition shows the oil pressure drops only 4 psi on right hand corners and as low as 7psi with braking AND a left hand corner. I'll get some screen shots of the data in a day or so.
The stock smog control system causes the engine to pump oil up into the sealed chamber above the transmission and depending on the engine this can be a significant loss of oil volume in the pan.
This is the baffle that by itself showed the left hand turn oil pressure loss seen in the above data.
This is a picture which shows the sealed chamber without the cover.
This is what the stock cover looks like in place.
This the cover with the 3 corners cut off.
This is the breather oil that goes to the bottom of the oil pan.
This breather hole is behind the flywheel.
These are pictures of the oil baffles that I'll be trying at Sears Point in early September. I'm very hopeful and confident that this will solve the problem. The engine in these pictures is the #2, #1 from the above data is coming out and getting a full bearing replacement.
