Before I put this on

Is an Accusump legal in Stock? I think it would really help my 340 live but I definitely don't want to go to the trouble then get bumped.
Thanks,
Mike

I think I have the 2 quart Morroso (no decal) electric shut off but I'll do a manual valve instead. More changes to the oil pump-passages also.

I ran a 3qt. unit and used an electric valve with a separate switch for it. This allowed us to prime the engine on a cold start. Shutting it off after starting the engine allowed it to charge back up. Turned the valve on going into the water, so it was active for the entire run, and then shut the valve off after making the turn off so the can could be recharged coming back the return road and/or back to the lanes. Worked great for me. I would want one on anything with a wet sump system.

I'm not understanding your procedure. Doesn't the valve need to be on in order to re-charge the chamber? I have one but haven't installed it yet but I was planning to have the valve connected so anytime the ignition switch was turned on the chamber valve would be open too.Thanks.

My thinking, might be wrong but, would the electrical switch run the battery down during the week then let the oil charge bleed off defeating the pre-lube benefited? Reason I was thinking mechanical.
By the way the cylinder is about 4" diameter and 18" long, how many quarts is that?

You would want to use a normally closed electric valve. Valve opens with power. Closed with no power.

You guys are overthinking it. You have the electric valve accumulator. It can only be open (allowing oil to flow from the accumulator) or closed (not allowing oil to flow from the accumulator). You open the valve before you start the engine for the first time (for example, at the first day at a race). You leave the valve open all day long, and at the end of the day, when it's time to put the car back in the trailer, the last thing you do is raise the engine RPM (and therefore, the oil pressure) a little bit, for a few seconds. This "charges" the accumulator. You then close the valve and repeat the procedure on Day 2, Day 3, etc.
