The Canton Accusump can do 2 and either 1 or 3 depending on how it is set up. You can go with a manual valve, no valve or an electric valve.

With the electric or manual, you can shut the valve trapping oil in the accumulator before you shut down the car. When you are ready to start the car you can open the valve and pre-lube the motor or keep the valve open and supply oil to the turbo as it spins down and forfeit the pre-lube function. Though I would imagine that the oil supply would be rapidly fired back in to the motor and the benefit to the turbo would be very short lived, otherwise it would not be able to provide the "oh **** lube" as Paul so eloquently put it.

With no valve, the accumulator will fire the oil back in to the motor as soon as the oil pressure drops below the pre-set threshold - almost as soon as the key is turned.

 

I might be. The problem I have is that I run very low on oil pressure during idle right now. If I wired an electronic valve (via the ignition switch) to an accumulator it would most likely have emptied by the time I shut the car down. I'd have to kill the valve while cruising, or increase my idle oil pressure.

 

Damn it. I can't get the Juniper Yournet java client installed on this Vista machine. What a pain in the *** this is going to be when people start switching to a more secure OS/browser. (the URL uses an expired SSL cert)

 

What does your oil pressure go down to at cruise/idle?

FWIW, you can set the accusump to activate at any pressure you desire, there may be a lower limit on this but I don't think there is...

 

Oh ya.... Pool chemicals are fun. When I openned the bottle of acid and it started smoking I was like 'oh ya, this is the real deal here'.

 

Look what I got Thursday

 

 

100 KPa idle (14.5 psi)
600 KPa cruise (87 psi)
700 KPa while cold (101.5 psi)

 

^^^^ measured at the oil galley plug on top of the block under the IC.

 

That is about what I see on my car, though I think I am in the 20+psi range at idle and have seen as high as 114 when cold.

My Mustang idles around 12-15psi and never goes over 55psi even at WOT...

 

Mine is measured at the sandwich adapter between the filter and block - oil temp and pressure are both measured there on my STi.

 

My cold pressure may be like yours. I just look at the gauge and if it's anywhere above the mid six range I mind my Ps and Qs.


The lowest pressure EPC valve I saw for the accusump was 20-25 is psi. so for me at idle it would be dumping oil.

 

It would be interesting to know how much of a difference there is between the two common locations.

If I added an oil cooler I would use a check valve and plumb the accusump into one of those lines. If the pressure was really higher down there then I guess there wouldn't be a problem.

 

The Accusump I have has a Schrader valve that you can use to set the desired presure threshold. I am fairly certain you can set any pre-load pressure you desire, once your oil pressure drops below that set level the Accusump will fire.

 

Could this be Paul's bastard son?
