    hi all!
    using a KB block in a door car,with a P&P wet sump oil pump and moroso pan,i have the following options regarding the oil filter location:using a moroso screen type filter plumbed to both 12 AN in/out of the pump ,and a straight 16 AN hose between the pan and pump inlet with a small cone filter in the pickup.
    or use an inline system one filter (16 AN)between the pan and pump and use a solid bypass loop on the 12 AN in/out of pump.
    redline 50W oil is used,and it is a blown alky roots 1/4 mile application.
    recommandations/thoughts highly appreciated.

    Use the System 1 inline. When I used the Moroso type screen I would see debris in the bearings switched to System 1 that all went away

    There's more than 20 times the surface area on the system one. Just be sure to run the correct micron mesh for the oil you run. I like the filter with the air chuck and the sight glass but, there's not much surface area there. I thought about running one of them before the system1. Just for the visual aid.

    thanks a lot for input!
    i'll run the system 1 between pan and pump then.

    We used one of those small cone screens in the pick-up line (dry sump) and saw bearing damage on the rods that we had never seen before. When we took the cone screen out, the damage went away.

    The bearings on top after one pass with the screen, the ones on the bottom after one pass without.

    You mean that cone filter was restricting oil flow?
    Has anyone experienced this problem with a wet sump system?
    What is the most commonly used micron mesh with 50w oil? (System 1 inline)

    I forget. I would call them to be sure.

    The computer showed normal oil pressure, but the evidence showed the bearings getting beat up without cause with a known tune-up. I suspect the cone may have been foaming the oil just enough to compromise its performance. Definitely not an apples/apples comparison between a wet & dry sump system however.

    I've always been concerned about putting filters on the suction side of the pump. It just seems like the pump would be able to push more oil through a restricted filter than it can suck through a restriction. I know... if you've got enough junk to restrict the suction you probably have bigger problems :)

    This is exactly what i was thinking:the closer the filter To the oil in the pan,the less junk is pushed up the top of the engine by the pump in case of breakage.i l talking about a wet sump system,of course
