accusump?

[Alxsmt]

does any1 have expierence with them? a guy i work with told me about them and said i should look into it. to me it seems like a good idea, but im not an expert and i dont know if i wanna deal with hooking it up

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.

taken from there site. they sound pretty good, in the end of the quote it says if the oil pressure is interrupted the accusump takes over this could be good if you happen to lose your oil pump.

or worse, a cam bearing....this extra oil will help prevent a horrible failure....


like my last 5 engines have met

But does it let you know when oil pressure has been lost and it is oiling the engine, giving you those precious moments to shut the engine down to prevent parts failure?

[geoffinbc]

Its called an accumulator and they are very popular. They basically fill in the void between wet sump shortcomings and dry sump prices. One side is filled with pressurized air and the other side with oil. The system has to be manually closed before engine shutoff to hold the oil pressure in and has to be opened again before startup. When the engine is running there is nothing the person has to do.

Unless you road race where you reach 1G in the corner or have a very fast drag car they are a complete waste of money. You would have to be an idiot to think you need one for a daily driver.

so you dont leave them "on"? you have to open a valve under the hood everytime?

the guy that told me about them said they will make sure all your parts have oil at the initial startup. and the initial startup causes most of the engine wear because of lack of oil

[pocket-rocket]

You could always put in a solenoid and a switch inside the car instead of opening a valve under the hood every time.

[geoffinbc]

No it is either a valve in the car, electric solenoid switch or a cable actuated lever. You wont have to open the hood.

[pocket-rocket]

You could also wire in the solenoid to your ignition switch and wait a few seconds to start you car. That would give the thing the time it needs to prelube your engine. Then when you shut it off, the solenoid shuts before the oil pressure in your engine drops.

ohh ok, thats sounds pretty good.

do you think i could just hook it up to where the oil pressure sensor goes with a T fitting?
