    Hey Everyone,

    For you guys who run the scavenger oiling system, do you run the metal booster plate in between the oil pump housing and the Scavenger oil block?

    Thank You,

    Doug,

    It has been a while since I put together a Scavenger style oiling system, so, if you use the booster plate then how does the oil get through the plate? Do you drill holes in the plate? Would there be a problem if you do not run the booster plate?

    Thanks!!!!

    John,
    Give Mike Phillips at AM&P a call. He's installed a LOT of these and has some good info on them. #1-270-729-5556

    John,
    You don't use the plate with ours or any others that I know of. Ours is hard anodized for wear. Don't use the plate.

    If I am understanding that system correctly, (which I don't think I am) How would it free up additional hp?

    It doesnt .. It just keeps the motor alive longer. They route the oil into the block where the stock oil pressure gage was, not through the front cover. And it pulls the oil through a size 14? AN fitting, an external line tapped into the oil pan.


    Finishline motorsports in Hastings Michigan set mine up. Sorry I am not sure about the "plate" ..

    The Scavenger uses the passages through the plate. The pressure side oil flow is the same as the oil filter cover I think. The suction side is the same as the filter cover relief and the relief valve is back fed through the supply passage in the cover. Bobb assured me I didn't need to port any of the passages out to match but I did anyway and it's scary how much pressure I have.

    The plate is only $15 from Autozone. Whether the piece is anodized or not the steel gears will eventually chew up the aluminum so I use the plate. If you didn't use it I suppose any scoring could be milled off but it would be cheaper to replace a $15 part. Just my opinion.

    They do free up horsepower by eliminating restriction on both sides of the pump. This means you can make the same pressure as before with less pump effort. I'm using the stock relief spring with the regulator turned way way out just to get down to 75 psi (that's with .003+ bearing clearance). The reality is the HP you gain is very minimal but saying it "frees up additional HP" sounds better than "you gain 1 or 2 HP". The scavenger also takes load off the cam gear and reducing the restriction on the suction side eliminates or reduces cavitation in the pump.

    I've never seen a TA piece installed and I don't know what the bypass connection is. It looks like maybe the pressure relief is bypassed externally rather than internally like the Scavenger. The rest of it looks like the basic Scavenger idea Bobb and Geoff have been doing for a long while.

    I agree, and that's what I thought...it's just that in TA's description of that system, they claim it free's up hp.

    Ah, Thanks! I figured if it free'd up hp it wouldn't be much...just couldn't figure how it would happen.
    Sounds like a good way to go
    Thanks! And sorry to hi-jack

    I have used this system in the past with great success. But now that I revisit the instalation of this system I have questions. I know that it will supply more volume simply because it removes all of the 90 degree turns in the stock cover and pump. That alone will increase volume and reduce the friction on the distributor gear and camshaft. But remember... This or any system will only flow the amount of oil that the smallest restriction point will allow. Which is why i am a bit hesitant in using the steel plate. For some reason I kind of remember modifying that plate. (I am getting old and just dont remember) :Do No:

    Has anyone ever done a test to see what amount of oil volume these systems will flow?

    For instance.. Original Oil Pump vs. T/A New Front Cover vs. Scavenger System?


    Food for thought!!!

    I brought this thread back because of this question ^. Has any one done this test yet and if so, what was the out come.
