Topic: Opinions on Oil Accumulators / Accusumps & electric water pumps

I heard some teams mention these offhandedly and even heard the official-types talk about how common / often electric water pumps are seen, but what's the general consensus? Are these things appropriately LeMons-esque or are they a bit uncitrus-y?

I know folks can make their own from leftover "blah blah blah" but I'm referring to store bought items?

I'm pretty sure that had I used an accusump (which I actually have a 3qt sump that I got at net $0 after stripping out and reselling a car) in the sChitroen I would not have developed that rod knock at PBIR. 1/2 qt low and long sweepers left the oil pickup uncovered, I'm sure of it.

And Mezeire is literally just down the street from me. Not sure what the net gain of an electric pump would be for my cars, but maybe having it to keep water circulating during pit stops (except refueling where the kill switch must be off) could help keep the head and head gaskets a little happier.

Accusumps are great to have, but budget killers, and I think the electric water pumps are mostly for drag racing.  If you could power your conventional pump w/ an electric motor, that would be quite lemonesque.

Re: Opinions on Oil Accumulators / Accusumps & electric water pumps

I have a related question: what is the manual control valve on an Accusump for?  Is it just for priming prior to starting?  They don't clearly say in the sales literature, and all I can picture is reaching over and adjusting the valve when diving into a corner, which, while exciting, really doesn't seem practical.

Re: Opinions on Oil Accumulators / Accusumps & electric water pumps

Yup, manual valve is to be closed when running before you shut it off to supply pressure for startup next time.  If you dont and the accumulator empties you can watch your oil pressure sit very low until the pump can fill up the accumulator.  Depends on how good/strong your oil pump is.  You leave it open when its running.

Really how hard could it be to make something like this from junk yard parts?

Re: Opinions on Oil Accumulators / Accusumps & electric water pumps

What if instead of having it turn the water pump, I just make it turn the alternator, and then hook the alternator to the electric motor?  Infinite power!

Re: Opinions on Oil Accumulators / Accusumps & electric water pumps

A metal-headed fire extinguisher makes an excellent oil surge-tank.
fittings at the gravitational bottom, the air-space makes the pressure. Not as efficient as an accusump, but expired extinguishers can be had pretty cheap, if not free.
(the accusump uses a spring for pressure - delivering full-force for the length ot the spring stroke.The extinguisher uses only the compressed air as pressure 'head')

~have not seen one on a Lemons car~

Re: Opinions on Oil Accumulators / Accusumps & electric water pumps

We threw a rod 19 laps into Arse-freeze, so I'm working hard to fit an Accusump into the budget for Sears Pointless.  I'm doing it the opposite way from Spank, though: selling pieces from a crashed parts car to get its engine down to zero value.  I have a used Accusump that should fit within my residual allowance...I hope.

Re: Opinions on Oil Accumulators / Accusumps & electric water pumps

You had better have hard documentation for the cost of the Accusump.   Them're cheeeter partss...          The  "um, I had this from an old race car and its therefore free" explanation will not fly.       You will have to account for current used value... and keep in mind that the judges (and I) have wireless cards for our computers and will look it up..

And it's got gauge on it! I seem to recall reading that gauges are exempt from budget. PLUS If there's no oil pressure, the other oil gauge won't work. Gotta put in an accusump to make sure my gauge works!

I actually took a bunch of pics before stripping the car out and returning it to street trim and selling it for a very hefty profit, so my bases are covered (if I actually cared about penalty laps).

The car I'm trying to make run reportedly has some ridiculously low oil capacity and a horrific lean angle, so to last more than 1.5 laps I've considered trying to put the accusump in.

That's about what I thought they were worth...       I just don't want someone claiming 'free'   

    Now for you Spank... an Accusump just allows you to carry and therefore spill more oil......

Re: Opinions on Oil Accumulators / Accusumps & electric water pumps

We found an accusump from a race car that had blown up so it was full of metal and other such internal metal parts.  We sent it to the manufacturer to get rebuilt and had a nice working accusump for less than $50 (can't remember exact price as that was three years ago).  Been running it since and has saved a motor in our car at least twice. if not more.

if your car can't handle this, its not a very good car. (note the shift light coming back on at 7300RPM as it spins down from 11,000rpm)


not to say that it was only making 25psi oil pressure at 7000rpm on half castrol 20w-50 and rislone ring seal by Sunday, but drivers figured out how to spin it that high 5 times in a single day

Re: Opinions on Oil Accumulators / Accusumps & electric water pumps

depending on your engines oil pan design...you might be better off with an internal solution...build you own baffles and trap doors to help keep the pickup covered in the corners.....  Depending on your exact car, there might even be earlier-later oil pan designs that help.....this is what we did in the 928..we retrograded the oil pan to an earlier version that cost almost nothing and the engine still runs.....vs the stock oil pan that blew the engine in 1 race....an accusump probably would have saved the 1st engine....but there wasn't room in the budget either

Just picked one up from Baltimore for $30 plus 17 shipping!! And yes i have the documentation.You just need to shop around. There are cheap ones out there.

or do the fire extinguisher bottle(s) deal. Just make sure you mount those vertically and the opening is down. That keeps the air (spring) in the top and they work right. This is just like an air tank on a water pumping system.
