Hi All

I'm planning on installing an Accusump to protect against low oil pressure with high lateral G forces. Attached is a plot of oil pressure vs RPM. The colour is lateral G. You can see lots of low oil pressure events with Gs over 0.7 or so. It has a Moroso oil baffle installed but this doesn't appear to work so well.

I want the accusump to discharge at pressures lower that 50psi and I'm on power.

The problem with this engine is that the idle oil pressure is way too low and will let the oil discharge into the sump when idling. You'll need to either select the 35 PSI valve and only turn it on once you are on the track, or select the 25PSI valve and not provide enough protection.

I have a standalone ECU and am planning on using the EPC valve of the Accusump but rather than a pressure switch to activate the value I'm thinking of using an output channel of the ECU to discharge the system. I need to think about the circumstances but probably something like:

Discharge system (EPC on)
- when oil temp is above 80C and
- when RPM is above 4500 and
- when oil pressure is below 50psi

I could even even work in accumulator pressure into the logic with another sensor but haven't though about this too much.

Would appreciate some comments on this approach.
