Was watching "Horsepower TV" and they were adding an Oil Accumulator to "Project Nova".
I realize the Nova has a dry -sump system , but do you guys think its applicable for us and is it worth it.
One good point that was brought up was it can be used to send oil up to the motor before start-up.

It looked like good insurance for start -ups, Hard acceleration, braking and even the 1%ers(Road Racers)

Any opinions?

Here is a link.

Great thought V, but seems like it would be a real pain in the *** that you have to get out of the truck, open the hood, and shut the valve off before turning the Engine off.

Then have to re-open the hood, and re-open the valve before starting it.

I'm more interested in the set up in Dragster Mag where you add a Vac pump. Thats designed to keep positive pressure against the rings creating a more Positive seal, "hence creating more compression and HP". Then as an added bonus it also
pre-lubes the engine for start ups, and gives you awesome vacum to keeps the brakes working in all situations

And it's Polished Billet or Chrome with Stainless Steel Lines

 

You can mount the pressurized system in the cab. That is how they did it.

This mod would probaly be geared more toward people who do not daily drive there Ls and guys that race alot (1/4 mile or Road coarse).
Also guys that store there Ls for the winter months w/o start-ups.

 

A few years ago, I saw a system called a Pre-Luber or a Post Oiler. Its used mostly for turbos to keep oil flow (and cooling) to the turbo bearing after shut down to extend life. It also pressurized the oil gallies prior to startup to prevent engine wear cause dry, drain back inspired, cold starts. The system uses an eletric pump installed inline with a remote oil cooler. The pump stop is controlled by a timer. For pump start, you turn the key to 'On' wait a few seconds for the pump to raise pressure, then start.

A system like this would not have to 'capture' the oil pressure and store in under pressure for use later as the accumulator does. The oil accumulator bottle is also a one shot deal. Once the pressure has bleed off - not more pre-charge ability.

Good Luck,

I have both [although indirectly]I use the oil pump as a diff pump and I have the accum as a safty for the engine.No you don't have to get out to turn it on.there is a option for an electric valve that fills the tank up even thou the power is off on the valve and when youput power to it it functions just like the ball vavle one.There is also a fully automatic one that works off fo oil psi will charge and discharge the tank depending on what you have the oil psi set at.

The one MAJOR thing is to use a 8# min line and use AN componets.I would not recomend putting inside the cab.If a line breaks you will get sprayed with hot oil.Mine is mounted under the truck on the frame rail.As with about everything else I made custom brackets to mount the tank.but they do sell bracket too.Stan

 

here are a few links to the valves and accum.Stan

I remember an older study where the SAE determined that up to half of all engine wear occurs at start-up, where the bearings are dry. Whether this applies to modern lubricants, I don't know.

But here's a rule of thumb I read on another board: If you use race tires, get an Accusump. The idea is that the stock oil pickup/pan cannot deal with the lateral g's provided by race tires, which will cause the engine to be starved for oil on hard cornering.

One thing is for sure -- it can't hurt.

 

I mounted mine where the spare tire was a couple of years ago. It has an electric actuator. I can't say if it has helped or not, but I don't see how it could hurt. I probably wouldn't put one in again unless I was a hard core road racer or something.

 

Thanks for the replies.

It is good to see a couple guys already have one with no issues.

I have to agree with the hard launches.

I will probaly not drive my L all winter and would think this might be a mod to do.
