need pics of accusump installations
 

Howdy all,

I'm about to put an accusump in my cobra. It is mostly a track toy at this point. I have a bunch of stuff shoved in the engine compartment and space is tight.

I was hoping folks here could provide photos of their installation to help me decide where to rearrange things to in order to fit the accusump.

Still not sure if I can fit the 3qt unit and may have to live with the 2qt version.

Thanks in advance for your help

Check with Gordon Levy...I think he has done several accusump intalls. He is near Phoenix.

Clois, thanks. FYI, I have no issues with the install or the fabrication. Just looking for ideas on where folks have put their accusumps.

Here's mine, 2 quart;

ItBites,

Here's mine:

It's a 3 quart size.

Undy and Tom,

Thanksmuch guys, just what i was looking for. BTW,any idea how long the EPC solenoid section is?

Anyone else?

E. Woods,

Mine is in about the same place as Tom Wells photo, but I'm not home to take a picture now. My engine compartment is a little roomier and my Accusump is mounted to the front frame crossmember. One of my goals was to keep the center of gravity as low as possible, so I put it as low as I could.

Since this picture was taken, the valve failed and I removed. Now I just have a 90* fitting at the bottom. I don't use it for pre-oiling.

Tommy and Bob,

Are you using the 2 qt or the 3 qt unit. Bob, yours looks like the 2 qt.

Any thoughts from y'all or anyone on the need for 3 vs 2 qts. Obviously, the 2 qt is easier to fit... I do track the car mostly.

ItBites,

I used the three quart size because it can hold the pressure up 50% longer than the two quart size. There are some long sweeping turns at places like Sebring and Daytona...

The valve & pressure switch combo on mine measures just under 5" from the face of the Accusump to where the nipple starts joining it to the rest of the plumbing, which is a simple line to the pressure gauge outlet on the BBF just above where the mechanical fuel pump used to go.

bobcowan,

I don't know how old the valve was that failed for you, but mine also failed - at least it leaked through the body a significant amount. The fix was the new-style valve from Canton - apparently they originally used valves from espresso machines :eek: I don't recall whether they had me send in the old one and replaced it without extra charge - at least that's what I think happened.

i just put one in mine, i run a 460 (with a stroker kit) and was having some wild oil pressure swings on the track. i changed to a canton low profile racing pan (which they have specifcially for cobras!) and the pan worked great!! i also added a 3qt accumulator and fabed a bracket so it sits above the radiator.

oil pressure around watkins glen is now 55+ psi instead of down near zero!!!

Thanks folks
 

I really appreciate this as I am not only looking at location, but also plumbing routing and and brackets.

My 540 Dart engine has pretty good oiling and i run a baffled pan, but I saw the pressure dip a couple of times at a track in AZ called Inde. I suspect that on a track with a big sweeper, it'd be worse. I'd like to use the 3 qt, but I have to relocate things already in that spot to fit like Tom's or sspan's. Vertical mounting appears limited to 2qt. Hmmm....

Here's mine!

I bought my 2qt. Accusump directly from Canton in 2007. Looking at their web site today, the electric valve does look completly different that the one I had. As I recall, it started leaking one day, and then wouldn't open. I threw it in the trash.

I'm also using Chris's road racing pan. So far, this set up has been flawless. I have a warning light that comes on at 25psi. Every once in a while it will flicker a little bit, but never comes on solid. And that only happens with hard braking, never with cornering.

2 qt = pre-lube duty only

3 qt = Track and pre-lube duty

E. Woods,

I have a 3 qt. Accusump and I'll echo what Tom Wells said. Here's the way I see it working. You start with an initial small charge of air inside the Accusump at relatively low pressure. When the engine starts and the oil system pressurizes, oil will force its way into the Accusump, compressing the air into a smaller space. When the pressure of the compressed air matches the oil pressure, the Accusump will be fully charged. The amount of oil in the Accusump and the amount of pressure it is under is determined by the size of the initial air charge and your engine's oil pressure.

When your engine loses oil pressure (e.g., a long sweeping turn pulls oil away from the pickup in the pan), the compressed air will begin to push oil back into the system. As oil is pushed out, the space for the air expands and its pressure will begin to drop. The rate at which it drops depends on how much air you had in the Accusump. The dilemma is this: If you start with a larger air charge, the pump will hold less oil, but it will maintain a higher pressure longer when it has to push it back into your engine. Conversely, you can use a smaller air charge to get more oil into the Accusump, but the pressure will drop more quickly when the Accusump is pushing oil back to the engine. Because neither situation is ideal, it is a good idea to have a larger Accusump so you can have both a larger oil reservoir and a larger air charge.

My 3 qt. is mounted under the passenger seat via the frame. With no clearence problems. :cool: Just a little extra braded hose to the hook up points. With the oil cooler, 8.5 qt. pan & lines. I'm running 12 qts. My engine bay is uncluttered & maint. is no problem! The car has been tracked @ a few events with no problem. If its location makes you nervous you could add a sheild if disired. my balence is right on 50/50 F/R & 50/50 L/R, no problem:3DSMILE:
