I only got one hit in the "performance " section so I posting here as well , hope the mods dont mind.

Anyone using an accumulator like this (or any other for that matter ) on their street machine ?

" The Accusump, the original automotive oil accumulator, is designed to provide the engine with oil pressure before the starter is even engaged.

An Accusump is a cylinder shaped aluminum storage container that acts as a reservoir of pressurized oil, to be released when there is a drop in the oil pressure.

The Accusump is connected to the pressure side of an engine's oiling system and is charged by the engines own oil pump.

Its simple, efficient design revolves around a hydraulic piston separating an air pre-charge side and the oil reservoir side.

On the oil side of the Accusump it has an outlet that goes into the engine's oiling system, controlled by a valve.

On the air side it's equipped with a pressure gauge and a Schrader air pre-load valve.

How Does an Accusump" Work?

On initial start-up when the valve on the oil side is opened the pressurized oil is released into the engine and therefore pre-lubricating the engine prior to start-up.

The Accusump holds whatever oil pressure the engine has at the time that it is shut off.

After the engine is started and the oil pump has taken over, oil is pumped back into the Accusump.

This moves the piston back and pressurizes the Accusump until it equalizes with engine's oil pressure.

While driving, if the engine's oil pressure is interrupted for any reason, the Accusump releases its oil reserve again, keeping the engine lubricated until the engine's oil pressure comes back to normal.

This release of oil could last from 15 to 60 seconds, depending on the size and speed of the engine.

In racing or hard driving conditions, the Accusump will automatically fill and discharge when needed as you corner, accelerate and brake. "

 

I installed one on a project car...sorry can't comment on performance just yet

 

Which one is it , the one by the rad ?

 

Damm
That's some sweet *** bodywork done to the chassis/body!
Setup looks very clean also. MSD placement is perfect!

Check the link below for the TB of choice and some other goodies you might like.

^you are right the body work was extensive...

^towards the bottom is some build pictures.

sorry, its the one by the rad. (pressure switch and solenoid mounted on the side)

the other one squeezes oil thru the turbo after shutdown...turbo timer, without the car running. Also with the MoTeC...the EWP and fans will continue to run after shutdown.

 

Hey dub, that car looks great....with so many pumps, ect you should probably consider upgrading the alt on that car. The stocker doesnt put out many amps at low rpms but all of those pumps probably pull the same current no matter if your idle or high rpms.

BTW - did you guys fab up that alt mounting braket? Looks nice, want to make another one to sell?

 

The accusump and turbo cooler are both passive components, no pumping.

The car will probably want to idle around 1500rpms, and doesn't have many electronics. Lights, EWP, ECU, cluster...on board PC, but on a separate circuit that can be shut off while the car is running.

Alt bracket - Pineapple sent us the pieces we had to weld it together.

BTW - that is a fully wired engine bay

 

I had one on a non-rotary car, never had the experience of suddenly losing oil pressure and have the accusump save the day (thank god). But I did have it wired so that it would release oil at the flick of a switch. At startup, I would hit the switch and watch the oil press gauge rise before I started the engine.

Dubulup, Im curious about the other oiler you mentioned, is that something like the accusump? What is the black cylinder on the driver fender? I need a better monitor...

it's actually blue.


here is a picture of it after I plumbed everything. It's kind of hard to tell, but the "turbo" line off the block goes thru a check valve into the T fitting, and fills the cooler (also to the turbo)...The cooler holds a charge pressure and when no pressure is pushing in...the oil is pushed out suppling oil to the turbo during spool down.

Probably overkill...but what isn't in that engine bay?

 

Thanks, So it does the same thing as the accusump, the way its described in that link. Can't quite tell what the difference is...

Do you use this in conjuntion with, or instead of, a turbo timer?

Also, I never knew honda made intercoolers. j/k.

 

the only difference is, there are no controls and it only feeds the turbo.

use it instead of a turbo timer.

 

sorry to bring this one back , but I got my hands on a new 1 quart accusump with an epc valve and pressure switch for only $200 ! I was thinking of putting it under the car along the PPF , but there isn't enough room ! only othr option I can think of is the hatch , Anyone got pictures of it mounted in their FD?

 

Anyone ?

 

I decided to put it in the hatch , in the spare tyre well beside my WI pump and accumulator. Will put up some pics soon.

 

has anyone sucessfully used aluminum hard line in their oil system ? It is supposed to be good up to 250 psi ! Just want to make sure .
