oil accumulator or baffled pan

[Titanium Man]

Hello,

do any of you guys run an oil accumulator to ensure you have proper oil pressure on , start up, going up steep hills, drag etc. Is a baffled, modded oil pan better? Which would you recommend?

Thanks

A good oil pan is always the first step in upgrading an oiling system. However, the laws of physics can sometimes be too much for even the most well engineered oil pan. This is where the Accusump comes in. With a well engineered oil pan and and Accusump you should have no oiling issues. Another option is to go with a full out dry sump oiling setup however, those setups can cost up to 5k and are overkill for most applications as well as being very intricate. Also as you have stated you can use it to pre oil the motor before starting it. Most common engine damage is done through pre start scuffing of the engine. By using an Accusump you can prevent that by discharging oil into the engine before cranking it over. Hope this helped, if you have any other questions please feel free to ask.

I use an accusump 3qt on my track car. I don't yet log oil pressure nor do I have extensive track time on my engine (only five events and maybe a total of 4000 miles much of which is street driving to/from the track) so I can't really prove any efficacy yet. I bought it in the chance it would save my engine as I was warned the 2g wet sump with it's almost non-baffled pan would not be sufficient. It was too costly at the time when I bought my engine to go to a dry sump.

I've since discussed the use of the accusump with Andrew Brilliant who used one for a brief time on his time attack eclipse and he said it was not fast enough reacting in his situation to resolve the oil pressure drops. He produces a lot more sustained lateral gs than any other eclipse out there though so it doesn't mean the accusump won't work for you. Andrew had to move to a dry sump system from Magnus Motorsports to resolve his oil pressure issues.

I'm going to continue my course with the accusump for now and work with Greengoblin in adding some baffling to a 2g pan to see how that holds, and of course add some oil pressure logging.

There is no doubt that a dry sump system is the way to go in any situation. However, the cost and intricacy are the pitfalls of it. Really the only way for a dry sump to fail is if the pump stops for some reason.

I'd love to talk to Andrew Brilliant to see what his experience was. Did he have an issue with how long it discharged or how quickly it took for the oil to reach the bearings? A 3qt Accusump will discharge for about 45 seconds in -10AN lines depending on the viscosity of the oil. Also if he was using an on/off valve the Accusump acts more as an increased oil capacity then to provide insurance in a long corner. In the case of the on/off valve the Accusump fluctuates it's capacity as the engine pressure rises and falls. This essentially means if you have two or three corners where your oil pressure is low the accusump will have limited duration of oiling in the final corner as it will be discharging the whole time. With the EPC switch as long as you don't dip below the threshold it will not discharge to ensure that when you get to the corner that is the most trouble you will have the full 45 seconds of oiling. We are always looking for good feedback though
