Thanks, "old" Jim. With age comes wisdom (for some). A common recommendation by Subaru road racers and autocrossers is to overfill the pan. My feeling is that the Accusump accomplishes a similar goal of making sure that the oil doesn't run out, but the more I think on it the Accusump is a...

Thanks for the input. To fill in a few blanks about what and why: I am 72 and though I had some sponsorship in SCCA racing when young, what I am doing now is track days in a race prepared (NASA ST2 level) car. I may chose to do a Time Attack one day before I hang up my spurs. I could be doing...

The solenoid valve is an option and is usually connected to the ignition so that it opens the Accusump when you turn the ignition on and closes it the second you turn the engine off. The valve is open during running of the engine and otherwise has no effect on whether oil flows in or out of the...

Someone said they could not see this when they went to the NASIOC link. I enhanced an oiling schematic so I could better visualize what's happening. With it and the dimensions it is straightforward to calculate areas in the galleries. But what does it all mean? I think I mentioned enlarging...

Subaru flat fours (a boxer engine design) are notorious for losing oil pressure under high lateral G's. The usual solution is using a dry sump. Dry sumps are expensive and complicated. They are, based on currently available remedies, unnecessary until you exceed 1.5 G's. I am at that threshold...

And what about maneuverability and inverted flight? We need more direction. Does it need to carry passengers or any payload? Didn't they try using the fuselage as a wing component as in "the flying wing"? Has that design been ruled out as too unstable, at least prior to computers and the B2?

That might say a lot. As someone who went to school part-time I was seldom prepared and tried to rely on my teachers, much as in high school. Didn't work for me.

If applicable, I found that being a nuisance in class did not curry favor from teachers. Frequently asking questions, which were either because I wasn't prepared or I wanted to give the teacher a hard time, due to a small mistake or weakness in their speaking on the topic, didn't get any...

I figured out part of the answer to my question. Venturi affect! I still don't know how to completely eliminate the effects of T'ing a sensor into a pressurized line where there is varying flow rate. Surely I was seeing a venturi affect that lowered pressure at the Accusump! I'm guessing if I...

I agree with all you said and have done all that, too. I have a nine quart capacity system or seven without the Accusump. I have a huge, 40 row Setrab oil cooler and external filter block, running a full-sized racing filter. It is just that I have read that some like to go to 85 PSI for small...

Current Accusumps use air pressure behind the piston to determine when the oil is introduced. You are right about using a manual valve! You have to remember to open it and close it. :rolleyes: I like to close it the moment I have revved the motor and have good pressure built in the Accusump...

I have an https://www.cantonracingproducts.com/cgi-bin/commerce.cgi?preadd=action&key=24-026, which is a mechanism which acts as a reserve supply of oil, if pressure should drop too far, at the end of a hose, connected to the rear of one of the...

I am retired. I have a hobby of building my own engines, transmissions and doing all the work to my cars and racing in advanced high performance driver education (HPDE) or "track day" formats. I used to road race... I am building an 818R kit car but currently have a fully track prepared Subaru...
