Accusump install

Set it to what number exactly?

Whatever number he wants.. whenever he wants.. on the fly.

Other than pre-start oiling and on the race track, the Accusump is likely going to be closed, so the pressure swings are not that big of a deal. A 3 quart Accusump will not deliver 3 quarts of oil. It is 3 qt total volume, that can be oil or air. If it's got 3qt of oil in it, then that's at zero psi and it won't help.

The last time I ran one, it was in a car that made about 65 psi (max). I put 30 psi air in the sump (empty) and let the car fill it. That gives about 1.5 quarts of oil at up to 30 psi (look up the ideal gas equation). I would run the crank case about 1 quart low (good for power) and let the pan over fill it a bit when fully discharged (not so much to be an issue).

They have different valves set at different pressures as you yourself have listed.

pick a pressure that would be ideal for you.
See if there is a valve that corresponds to that pressure.

Ahhh... So it is not MY reading comprehension that is in question.

"I never said there is a valve you can manually set. "

So to my statement

So you were trying to say that I am stupid and all I have to do is GOOGLE it or RTFM and I would have my answer.

So yes you did say there was such a thing, just not directly and with a little attitude.

Maybe YOU are the one who needs to learn how to google and work on your reading conprehension before insinuating that someone ELSE is the dumb ass.

SO now back to the ORIGINAL POINT that I was responding to:

Not the 3-quart model, anyway. Otherwise the oil level in the engine is going to be all over the map as well. Am I missing something here? Either you're 2.5 quarts low at 7000 RPM or 2.5 quarts over-full at 1000 RPM. Or a little of each perhaps.

Accusump also make a 1-quart model that might be a better choice for these little engines. The 3-quart accusump was fine in my V8, where oil pressure stays in a 40-PSI range. A 1-quart sump can still pre-lube the engine and provide some high-rpm stability, without making the oil level vary so much.

I will reiterrate: Too Bad ACCUSUMP does not make an electric valve with an adjustable setpoint so that we could set it BELOW 15 PSI

Ok buddy..

good luck with your install

I' dlove to see some picture of the accusump install, where you installed it , where the piping is routed , ect...

always good insurance to have one of these on non dry sump engine on the track

Other best thing, a dry sump system, but I have not seen anybody selling a kit ready to install.

I Emailed ARE dry sump folks. They responded that they have no plans for a kit for the FA20 engine.

Here's where we mounted it in the race car.

did you get before and after logs of the oil pressure?

Where are the details on this car?

The details are... mostly on facebook but we will be glad to answer any questions you have.

No logs, it didn't run into any pressure issues last season, but the car spent most of the season broken with transmission issues. That will be resolved with the hollinger.

With it setup as a manual valve operation as in the pic, the sump will constantly charge & discharge with the oil pressure in the engine.

How do you choose to operate it?
Do you close the valve after the sump is up to pressure, and drive that way, or do you leave it open the whole time and hope you remember to shut it off before you kill the engine?

Curious

[puma]

i don't want to answer for him but we had the same setup on our previous racecar and it is pretty much like you said, always open and you need to shut it before you stop the car.


What we usualy did was to raise the rpm a little to raise the pressure and than shut the valve.


If the car hasn't been started for a long time, you can open the valve prior to starting the car, this will help to bring oïl to the engine to avoid it running dry. You need to shut it back up before starting though because the pressure will take longer to build, this is important that the valve always be shut when you start the car.


If i install an other one, i'll have an electric valve because the pilot forgot about it too often.

can you post the link to Facebook or send it in PM?

I am curious about the plumbing as well. And my biggest problem with the manual version is that it is indeed too much to remember. I think electric is the way to go. When you are about to get on the track or coming back from it, the last thing you want to do is going through a checklist for all the button you have to press.

PS: is that an AIM MXG dash ?
