Hey Everyone (IMG:style_emoticons/default/biggrin.gif)
Here's what I'm running
2258cc
10.5 to 1 compression
40 webers
494 web cam
type 1 oil pump
mocal oil cooler 25 row
mocal sandwich w/thermostat adapter
accusump 2 quart
Brad Penn Air-cooled oil 15-50 (5 1/2 quarts)

Let me explain my set-up
The oil cooler is a rear mount under the car on the passenger side rear. I made some duct work and its almost vertical to catch the most air as possible.
Track conditions
Sunny, low 80s, 30min sessions

question 1) With that cooler I didn't expect to run in the 230f oil temps. Is 230f acceptable?
question 2) I also have some oil on the top of the case /engine tin pooling. 1-2 side.
It only happens under WOT. Any ideas?
question 3) I never set-up an accusump and I don't like it so far.
It over fills the case at shut-off. Do I have to much air in it (9lbs)?
Other then my oil questions, I had a great time. Ran a 2:51. My new best time.

Took the screen off and added brackets to hold the bumper in place.

I was at it with my cooler today too. Added a ducting from the fan in the front valance back to the cooler and added to Chris's shroud to scoop more air from the under car stream.

I ended up removing the flap on the passenger side like you did.

Can't wait till next weekend! I am going to pit with the Condor crew by turn 17, do you mind moving down that way? Going to try to get there early.

Hey Miguel,
If my cooler doesn't work to my liking this weekend then front cooler it is. Did you figure out your pressure drop? I wonder if you had enough oil in your car. When I first installed my accusump I had problems with "knowing" my oil level.

Looking forward to seeing your new duct work. (IMG:style_emoticons/default/biggrin.gif)

I'll be pitting with my corvette buddy. I'm bringing my bike, I'll be down there all day!

Cool, I am going to try and bring mine too.

Oil, maybe. Hopefully.

It looks like I had the perfect storm. We were not able to find any single issue big enough to say definitively this was it. The pre-charge on the accusump was low, 2psi. I had reconnected the breather hose from the stove pipe to the catch can and I think this was causing an over pressure situation in the crank. Which in turn pushed oil to the heads and in to the catch can over filling it and spilling out. And the smaller secondary relief valve was as rusty as the main one.

I know I lost some oil, maybe the +1 quart that I was over filled, but at the end of the day the dip stick still read full so I was not critically low.

I drained the oil check the accusump pre-charge. Checked for leaks on the air side, held 60 psi for 8 hours. Bleed down the 60 psi to 10 psi and refilled the oil system.

There was a question about the tuna can pick up and the pick up tube to case o-rings but those checked out.

Chris sent me a new catch can in a giffy and got it installed yesterday. I love his customer support!

Replaced the pressure relief piston. But I am going to bring a rig to jamb it closed if the problem persists.

I am not happy about not finding a specific failure point and going back to the track with out getting a chance to test it but I don't have much of a choice. Need to find a big empty parking lot at some point.

Shrug.

Miguel
