I bought one 3qt unit with manual valve plus a solenoid on 12Vdc hooked the the run side of ignition. I don’t drive every day or every week, but I know how much it cost in my time to supply a machine shop with damaged rotating parts if the engine doesn’t last about 4-9 more years. Why not last 20 years! Thank you kindly for the information you provided. Peachy great! ASE Master Tech 78. Retired!
Hi guys. Great video. I just added an accumulator on my nova for my 441 sbc. I have mine feeding through my remote filter mount through an OUT port that goes back to my Iron Eagle block. One thing just hit me was some people use a solenoid with a pressure switch. Say it's 40psi. It will only open if it dips it will only open below that set point. Do you think that might prevent the bouncing you saw with it trying to fill it AND feed the engine? Just curious.
It’s possible. Something like a switch with a one way check valve in it so it would bleed pressure one way but not the other. Unfortunately because things came up, we really only had a limited amount of testing done before I finished the video… but we plan to continue testing it to see why the accumulator seemed to prolong the oiling issue. I’ve seen these accumulators work well, and other times not, depending on what the actual oiling problem is in the engine, so I was skeptical from the beginning. It seems that an accumulator really can only be a supplemental oil supply, not a replacement. That LS in the TransAm needs a better oil pan and sump to keep the pickup tube in the oil, THEN, the accumulator can do its job.
I actually have a theory on the oil pressure fluctuating during the pass. When I added the accumulator, I never actually added any oil on top of it as the 6 quart pan was already holding 7 quarts of oil, so I had assumed that the extra quart would have gone into the AN line and into the accumulator. What I think is probably happening is the accumulator IS doing it’s job, but the pan is still having oil climb up the back of the stock pan, which is then putting air into the system, causing the pressure to fluctuate. I have since added another 16 ounces of oil but have not yet taken it to the track to see if it would fix the issue. Regardless… The stock F body pan definitely needs to be upgraded to a more “drag race“ friendly pan.
Based off of those logs, it looks like the stock F body pan is just not going to cut it. When that 6.0 is pulled, it will be getting an upgraded Moroso drag racing pan. I was honestly expecting the accumulator to perform a little better but as you said, “band aid on a bullet hole.”
Absolutely! Upgrading the pan will definitely be the best option. As we kinda showed, the accumulator is better in a supporting role, but it can’t fix a major pressure issue
She is doing great! Just been very busy lately. We’ve been trying to work on videos for her, but she’s been so busy with her purse making all it’s been hard

How’s Amy? I see she hasn’t posted any youvtube videos in a long time.
She is doing great! Just been very busy lately. We’ve been trying to work on videos for her, but she’s been so busy with her purse making all it’s been hard
Glad she is doing great. ❤
