Accusump advice?

[R1 Indy]

Im in the progress of fitting a 3qt accusump to my 08 R1 Indy.

It's got the standard electric valve, which I will have wired to a switch on dash, which I will only really have turned on while on track.

Now I don't 100% understand how these things work, from my understanding of how they work is it right that if I was on throttle and oil pressure was around 80psi, then I take the foot off the gas to slow down and pressure goes to around 40psi, would it then start discharging oil?

Or at what point will it discharge?

As don't want to find that as the oil pressure changes that it's constantly discharging oil?


My other thought is to fit a oil pressure switch, connected to a relay, so it only turned the accusump on below this pressure? Similar to the EPC valve?


Can anyone give me any advice on how I should run it?

Cheers

Your best route is to wire it, as you say, through a relay and oil pressure switch. Supply the power from the ignition do not use a switch on the dash. Use a race oil switch as a standard one only switches at about 2psi so in an oil surge the damage will be done before the Accusump can react.

The system is now active at all times.
When you start the engine from cold turn on the ignition and wait.....during this pause the Accusump will push oil through the bearings before you turn the engine over.
When you start the oil pressure will refill the Accusump.
During normal running the Accusump will just sit there doing nothing until the pressure drops at which point it will start adding oil.
Make sure the Accusump is full when checking the oil level and fill to the normal mark.

Don't know a lot about Accusumps but...

Keep in mind that the R1 has oil pressure when hot is below 10psi at idle. Every time you slow won't it be discharging and then refilling?
