Please can someone advise me on how to work out what size accusump you need for different applications?

Thinking of using one and can't find anything on the net :euge:

I have used search button too and although I have come across helpful info, none answer my question.

Thanks in advance :smokin:

Bexta :thumbs:
 
How do you know whether it's too small or too big though or doesn't it really matter? I'd imagine it does otherwise they wouldn't make them in different sizes :wack:

Thanks though sweet, anyone else help??

Bizzle-I would have thought you'd be the man in the know???

:thumbs:
 
Well I guess the reason they don't have fitment info on their website is they don't know :wack:

They're gonna get back to me:euge:

The accusump site is dreadful too. :rolleyes: It's like they just want to sell shiny things, rather than give you any technical data.

I suppose as the device is only supposed to provide a reservoir of pressurised oil, the size is dependant on your peak oil flow rate and the number of seconds protection you feel you need. Given the drifting application could well have some very long corners at peak leteral G while simultaneously doing max rpm I suppose you'd want as big a one as you can afford/fit.
 
Yeah, and then keep an eye on oil pressure whilst skidding. The reservoir in them will need time to recharge, once its empty you are reliant on the pump picking up oil again, to maintain oil pressure and re-charge.

Bear in mind that if you have a large capacity one and you find it empties a lot during a session then all that oil is then sloshing about in the oil pan until it can be put back into the reservoir, which wont be a nice look for the engine. Although with the extra oil now available then I guess there is more chance of the oil pick-up being submerged ?

Dry sump is where it's at or a deep, baffled sump in the oil pan.

Ooh, good point - if the oil in the sump get deep enough for the crank to hit it you'll get aeration of the oil, and christ knows what that'll do to the oil pump as they're not really designed to pump bubbles. You'd get loads of oil mist in the breather system too, although no one really cares about if you have a catch can.
 
Dry sump really isn't ideal-I did look into it but it's just not practical maintenance wise.

Thinking custom sump + accusump with N1/Tomei oil pump all rolled together should do the job nicely :nod:
 
Ive come accross this problem too, what engine are you running?

Im looking for one for my rb25, I've come accross a 6 pint on on ebay at not bad money(would be better if the exchange rate wasn't so shit) :cry:

CANTON 3 QUART ACCUSUMP OIL ACCUMULATOR WITH EPC VALVE : eBay Motors (item 360242957905 end time Apr-11-10 07:44:52 PDT)

What does everyone think?

WOuld it be better to ru a standard sump with this kit, as less chance of oil surges, as there would be now wings for the oil to fly into?

Cheers :thumbs:
 
I haven't found a definiative answer yet but as soon as I find out I'll let you know :thumbs:

I'm in talks with merlin and they are gonna get back to me.

I'll be running a 2.5 also ;)
 
Cheers

I plan on locating mine in the boot, is there any problems associated with this?

I was thinking it will allow a larger capacity of oil, although a lot of drag cars locate it at the fron of the car, under the intercooler, i think it would be bad enough a tyre wall eating your intercooler, without draining the engine of oil too?
 
Alot of people boot mount them-it's fine. I'll be mounting mine in car also-but near the front so I can keep an eye on the gauge :)

it only lets oil out when pressure gets down to cetain psi. as soon as the oil pickup has something to get hold of it re-fills it straight away. the only way to flood the engine is to leave the manual valve open with the engine off.
