oil accumulator skool

LS1 engine


Someone please school me on accumulators. I got one from FOA. There instruction is less than ideal. From a discussion with someone else... they are supposed to be on the pressure side of the oiling system. I thought you could just tap into the oil pan, maybe not? If you need to go to the pressure side, how/where do you do that?

Thanks, KC

Not sure where on the LS1, but it does need to be in a pressurized galley. The accumulator will be pressurized to your "normal" psi, if the pressure at the outlet drops below the pressure in the accumulator it adds it's oil into the engine, when pressure stabalizes the engine pressure will refill the accumulator.

Thanks DemonDave, I get the basic Idea of how it works, thats why I bought it. I guess my main question is where to tap into the oil system on a LS1. Pan or HP side. Makes sense to use the HP side, so I guess the real question is where to tap into the HP side on a LS1.

I was pretty sure you knew, just backing up the response and giving those who don't know the idea.

I did a little looking and found this: "It installs simply with only one oil line connecting it. Through this line the Accusump fills and discharges. This oil line may be plumbed into the return line of an oil cooler or remote filter using a "T" fitting, into an oil input sandwich adapter, or directly into one of the engines oil galleys."

on this website, http://www.livermoreperformance.com/canton_accusump.html

Looks like the easiest way will be a sandwich adapter for the oil filter, there may be a plug in one of the oil galleys on the side of the block, but I'm not htat familiar with the LS1's

Just got this from LS1tech. I'll check it out tomorrow.

It goes were the oil galley plug is right behind the alternator.

I am not sure if its better to do it with the fitting in the galley or the spacer under the oil filter. There are plumbing instructions on cantons website.

Spacer between the block and filter is not an option unless I go with a remote setup. It will hang down below the pan and can be hit.

I would plumb it into that little piece on the side of the block that I tapped for the oil pressure sender.. well, I guess it's technically on the pan, but it's on the pressure side. You know the one I'm talking about, Kevin...

Thats where I've been wanting to put it all along. -8AN or larger is recommended. So that is not big enough. -6AN is about as large as can fit.

You could run the shorter car oil filter, and that would let you run the sandwich plate without it hanging too low...

I'll have to look around on the engine and see where that bolt is they spoke of

I am runnung the short car filter. The port they spoke of is a big plug. Will look at it seriously.

Here is what Mike from FOA told me.

LS 1, I think is the same as an LS2 which I have and I attached it to the port in the back of the intake manifold where the oil comes out to the oil pressure switch. I took mine off and taped it to 1/2 NPT but it is fine with 3/8" NPT ............

Bottom line you can hook it up where ever you want as long as it is High Pressure, The oil pressure lines generally will not work. If you have any doubt you need to check the pressure before you hook it up.

Drill out this hole and tap it. It is on the pressure side of the oil system

Post #6 & Post #8 already address this. Port needs to be tapped at least 3/8 NPT. That port is not big enough.
