Accusump

I have a 6 quart pan and am going to buy an accusump, which brand/capacity do you use?, and what features do you like/dislike about the unit you chose?

Thanks

I used the large Moroso unit. Ours were manual but might use electric unit. I felt it might be just one more thing to screw up at a race. Some people leave it full after a race to preoil before restart next week I did not. I left the pan full with the unit OFF till I was ready to make a run. Then all oil was hot and opened the valve manually before the run. Closed it again after the run so the instant you restart in the pits all pressure goes to the bearings etc not the Accusump. Worked well in all my previous cars this way. Good Luck. Remember the set up and oil volume you run will need to be carefully set so the sump doesnt starve the motor by getting the pan level too low.

I also use the large Moroso one. One thing that is very important with the Moroso or any other unit is that you do keep it full. The time it takes to fill it up when you start the engine is very hard on your bearings and cam. It’s like running the engine for 10 seconds without oil if you start with it empty.
But I do exactly as Mr. Butler when I want to run fast I use my pan heaters to preheat the oil.
What’s best is to store the car with the accumulator full so you don’t have that initial dry start. Pre lube before start up, run the motor for a short time to get everything wet and then shut it off and let the accumulator drain and then start heating your oil.

Has anyone tried putting a heater on their accumulator?

i have the accusump ,it has an 12 volt electric valve that will allow oil to fill one way and not come back,the hobs switch is set at 35 psi and if oil presure drops below that point it will supply oil to the sandwich plate ,also when starting it will prime engine before started,when changing oil you can just change the oil thats in the pan and filter so you always have oil in the accusump,or if you change out the entire amount of oil ,pull the distrbutor and prime it that way,(no dry starts "ever"),its good insurance and its nice to see oil presure build before the engine is even started
