Re: Accusump - pros & cons
 

So now that the dust has settled and I am out of popcorn and beer, I am very curious as to why no one has mentioned Master Lube accumulator which also has engine pre lube as an option. Other than they don't pay contingency. I have been using this unit for over 15 plus years now and I believe it works great. Great people to deal with and very informative. Made here in the USA. They advertise in the National dragster. It works a little different from the piston type (Moroso, Canton) units. For what its worth, yes this saved my crank shaft and engine about five years ago. So I am curious to hear other opinions on this product. Also I will add that IMO regardless of what product you use, there is no down side to having an accumulator and pre lube set up on any engine other than adding a few valuable pounds.

Honestly I always thought this looked like a good product! I run the Moroso 1.5 quart accumulator which I’m happy with, mostly because I was able to install it in a lay down position which worked with limited mounting spots. I would also be curious to see who else likes the Master Lube deal.

Re: Accusump - pros & cons
 

Drew, I had one of those years ago and it worked well but having to mount it vertical was a problem so I moved to the Moroso simply for mounting convenience in my roadster. I gave the Masterlube to a Mopar racer buddy and he is still using it.

Question here, what’s the best way, in y’all’s opinion, to plumb back into system? Back above the pump or back to sump? I know it would need to be charged by the pump and a diverted valve to go back to sump on the second option. I feel it would be more beneficial for the oil pump to supply pressure than the accusump itself. Am I missing something or over thinking? You guys have been in this so long I’ll respect your ideas.

Re: Accusump - pros & cons
 

You do not plumb the Accusump back to the crankcase, it has a single line that goes from an oil feed passage, the oil stays inside the tank until the oil pressure drops to a certain point, and then the pressurized oil in the tank is back fed into the oil passages, and to the bearings and other components normally fed thru the engines oiling system. When oil pressure is restored, the presure fills the tank back up.

Re: Accusump - pros & cons
 

Yes, the Master Lube does have to be mounted vertical which I mounted it on the fire wall That could be an issue with Stockers having the space. Rory is correct on the plumbing. I use a double pole switch for the solenoid. Any time I start the car when it has sat for a day or more, I turn on the switch and ignition and it dumps the 1.5 Qts I have in it, into the engine. When doing so the oil pressure will rise. Once the oil pressure drops back to zero then everything is pre lubed and start the car. While the car is running and warming up the tank will refill. I keep the switch off until after my burnout. Before I stage the car I turn the switch on and bingo, instant insurance. At the end of the run heading back to the pits I turn the switch off. The tank will re fill itself. As long as you follow the pre charge instructions and check it once in a while it very simple.
Would love to hear more input.

I just have to:D

First let me remind you that because you don't have a S/SS car, nor compete in stock/super stock like myself, some here feel that not only is your opinion not valid but it's not wanted unless of course it aligns with the OP and/or the majority that reply, NOT the majority of stock/super stock racers that do not have an accumsump!

Now that said, why do you have oil control issues with your SST engine/car that based on my quick search appears to be a lower powered car.

Thanks Drew! Great explanation .
