Anyone have experience with Accusump?

Hi everyone,
I was wondering if anybody has any experience with an oil accumulator such as Accusump. If so, would you mind sharing your experience? Any advice would be appreciated, thanks!

What do you want to know? I haven't spun another rod bearing since I've been using it.
The only thing I'd recommend is using the manual valve, not the electronic one. The electronic one, IMO, generally doesn't act how I want it to - lets pressure build too slowly. I thought I'd like it because I wouldn't have to remember, but I don't...

zzyzx,
thanks for the reply. I was just curious as to whether you had experienced any oil pressure or other problems since installing the Accusump. In another words, does it work as advertised? I also was dead set on running the electronic valve but after reading your post I am definitely having second thoughts. With the manual valve, are there any adverse effects to forgetting to open or close it? Thanks again for the advice.

I second getting a manual valve. For the same reasons and stated above and because a manual valve has much less of a chance of failing.

thanks for your reply. Do you foresee any potentially adverse effects from forgetting to open or close the valve?

Well if you forget to open the valve before starting there is a chance you could get oil starvation. If you forget to close the valve before shutting it off you just won't have any way to pressurize the engine with oil when you go to start it back up.

solo2,
So if I forget to open or close the valve I simply lose the benefits of the accusump, but do not stand to do any more damage than if it were not to be installed?

omahasubaru,
that sounds like good advice. my only concern is that I will forget to open or close the valve when I take the car out for the occassional weekend drive, but it sounds like it should be okay even if I forget to open or close it for the occassional grocery run.

I would think your better off forgetting to close it then forgetting to open it back up. If you forget to close it no harm done just no way to pressurize the oil system before start up. If you forget to open it then you could be dealing with oil starvation is not enough oil is in the pan. This is basically what I stated above. Hope this helps you out.

Hey guys,
I just want to offer my sincere thanks for all of your very helpful replies. I have decided to go with the accusump with a manual valve, hopefully this will keep my motor in one piece!

I was simply stating if there isn't enough in the pan not that the Accusump carries any bit of the normal capacity.

Hate to bump a old thread but how many quart accusump units are you guys running? Also when you state you don't like the electric valves, are you talking about the E.P.C. Valve?
I was thinking 2 quart unit with the 20-25 psi E.P.C. Valve... Can't do anything but help motor life. With the added insurance of the oil cooler and accusump I might just entertain the idea of spinning the stock long block upto 7500 -7750 rpm's...

The accumulator doesn't fix oiling problems other than starvation - like in a long turn.
It doesn't change the physics of the system. Yes, it holds more oil and there is some heat radiation but that's about it.

the accusump is of useful benefit to guys tracking their cars - and also of benefit is a true baffled sump. Not a ghetto one that you see being sold in some places - but a truly internally baffled unit.
the boxer and the pan layout with the oil return and the head breather design (especially on the 2.5s) means that when you pull Gs, there is a high probability of either losing the oil in the head (too much oil), or losing pressure (too low of oil, which people end up with such that it doesn't pour out of the head breather). You need to have a baffle and a reservoir. The cooler doesn't have much to do with it, unless you are truly heating it to the point of pressure loss (which i seriously doubt). We reccomend the accusump on all our customer track cars. And a baffled sump, and a surge tank, etc. etc. the 35psi EPC valve works fine. If you want fgaster fill rates (i.e. twisty track or whatever) then bore it out or go manual.
If you are running slicks, and a fast car, and you drive it fast, all of the above and more is needed. NONE of this is going to give you 8000 rpm. Some head work would, though.

Hmmm...I was planning on getting an oil cooler, but hadn't thought of an Accusump. Does anyone have a setup with an oil cooler and an Acuusump installed?

However I don't have quite the budget to do everything I want to do so I have to choose. Would you recommend a oil pan or accusump given you had to choose???

I don't know if there are any Subies running around with that setup, but it's pretty common in the Mustang/Camaro/Corvette open tracking crowd. The plumbing would be the same, of course, you'd just need to work out where to mount the pieces parts.
[quote=Ryokosman]patr - I hadn't thought about a baffled oil pan. I didn't know anyone made them for subaru's...[/quote]
The only (potential) one I've seen is a pan from ARC advertised on a couple of the websites of guys that import hard-to-find Japanese parts. When I emailed about it the guy really didn't have any info, as nobody had ever bought one from him.

is there really a reason for this? I keep hearing how the boxer engines are some of the best at cooling.
although a baffled pan sounds like a worthy investment. Maybe we can get someone to start making some?

depends on how hard you want to run your car on track and how much extra engine insurance you can afford. considering the average track day in a wrx/sti will cost about a grand (entry, gas, brakes, tires, misc)... ~$300 for an oil cooler isnt too bad.
i personally have gone with out one for a while at 300whp but have one now that i am moving up to ~450whp...

I have over 325 whp and track without a cooler now too. I don't have any guages but I know my oils gotta be kookin! It noticeably turns alot darker after a track day.
My car also gets rear hot out on track. The factory temp guage points about the 3/4 hot mark while on track. The oils gotta be feelin the heat. :(
Probably not real good for the motor but I run a 50/50 mix of 93 and 101 on a 91 oct map so I feel confident that I'm not gonna run into det issues.
I've already got a Process West oil cooler waiting to be installed.

I've got 300whp, and my oil temps with Mobil 1 get up to 125C pretty easily, which is in the range where an oil cooler would be desired. And that's in like 60-70 degree ambient weather. If I back off a bit (part throttle in 5th gear) the oil will drop back to about 120C, but flooring it down every straight, every lap, definitely gets my oil hot. Oil cooler is on the list of things to do before I start tracking the STI again regularly. (race tires, more front camber, and brake ducts are also on that list).

i've ran my stx wrx (~220whp) at the track and have been able to get mobil 1 oil to start losing pressure after about 8-10 laps. i've never used mobil 1 since... i would definitly recommend a oil cooler for the track.

I hate to break it to you, but any oil is going to break down if you overheat the hell out of it (as you apparently did). At the track today my oil temps were getting as high as 270ish, but oil pressure never dropped off - all on Mobil1 5W-30. FWIW, I'm measuring oil temp at the oil filter.

Hi guys,
it's an old thread but anyways, i have a few questions.
I have been thinking about the accusump for a while. Where do you connect this? Do you use sandwich plate in oil filter or what? Is anyone of you using a dry sump? We have had problems with spun rod bearings. Latest Sti engine died last weekend. We rebuild the engine 2000miles ago with ACL bearings and all the new hardware, oil pump, rebuild rods, tensioners etc. We broke 2 of these engines last summer, and the other one is still working but its in a street car. Iam not sure if this con rod bearing problem could be solved with accusump, but it is quite cheap way to try it. How much oil pressure do you have in your track cars? at idle and in boost?

All the EFI ST-2 Cars up here in the northeast run coolers/accusumps.. I don't see a problem with it.
I'd advise a cooler on a turbo car if you're going to be beating the hell out of it on the track. I'd recommend get a thermostatically controlled housing so it will warm up to temp as fast as stock (bypass the cooler) especially if you take it out on the road.
My oil temps with an n/a on a rainy day are like 250+ without a cooler... That's the next addition to my car.

Apologies for digging up an old thread but I have a couple of questions regarding the fitment of an accusump.
If I only want oil surge protection and not pre-oiling, once the system has been setup (i.e pressurized) can I simply leave the valve always open?
I'm thinking of connecting it to one of the oil galleries in the block. How do I know the oil pressure supplied by the accusump is going to the right place as one cannot insert a one way check valve in this scenario?
Cheers.
