Oil Accumulator
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 use to run an alfa with one of those in it....I'm not convinced that its worth the money
If your having oil pressure drop do to oil slosh than you should fix the problem (baffles etc.)
as far as dry start up yes it will help but IMHO as long as you warm up a motor properly this
is probably going to fall very low on the reasons for engine failure chart.
as for its claim to save your motor if you have an unexpected loss of oil pressure, If the system works the way its suppose to you will never know that you lost OP untill the accumulator is empty so it may give you a couple of extra seconds before the big red light comes on but your still going to end up in the same situation of having no op and hopeing you catch it in time.
just my opinion but i would put the money elsewhere.

I have one, but mainly it seems to help by providing pre-oiling before starting. I like seeing pressure before I start. Without it, it takes 2 or 3 seconds of running my engine without oil pressure while the oil fills two coolers and a big oil filter and several feet of AN hose before it gets to the motor bearings. I am not convinced that it really helps me any on the race track.
