    Default Custom oil cooler

    Anyone ever try making a water cooled oil cooler? Would the coil in a can design filled with fresh lake water work?

    Need another project and cant justify the cost of a new Olsen unit. I'd appreciate any input.

    There was a thread on here awhile ago, that talked about this. I'll try to dig it up.

    now thats a unique idea ...there are Kool cans for gas, why not one for oil...i would think -10AN SS line coiled in a can with water running thru it might be just the ticket!...could be made very easely!...shoot us ur suggestions & see what comes back

    That would be a shell and tube heat exchanger. Just not a very good one. It would work but the more tubes the better.

    Now the guy in the shop next door to me just happens to make those. Maybe if you do everything he would swage the tubes in the sheets for you. Stop by sometime and we can go over there and talk to him.

    You can make one and when it's done you'll know why they cost so much.

    the length of the coil of tubing you would need to lower the temp enough to matter, would be so long it cause a major pressure drop in your oil pressure. There are dozens of differant designs oil coolers out there, why do you feel you need to make a custom one?http://www.flatplate.com/products_refCH.htm
    these coolers have the lowest pressure drop, and the highest temp exchange of all the designs and come in a zillion configs. Bust out your wallet

    Sleeper - that keeps your oil temp down enough ? How long to you run at higher rpm at a time ? Normal water temp you ride in ?

    I have found - they way I run anyway ie: anywhere from 10 minutes to 30+ min at or near WOT at times - the 3" x 18" coolers just enough on 400-550hp or so. Many have to use the 3x22" 's with bigger motors.

    Our lake temp goes (while boating) from 40°-70°-40°. Yes, it freezes but we don't boat then. LOL.

    Brendellajet - where you looking for the tube type as Sleeper has or the plate style like these?: http://www.cpperformance.com/SearchR...CategoryID=141

    Thumb thru here too for more ideas: http://www.cpperformance.com/SearchR...CategoryID=432

    Those just look kind of ghetto to me-especially for $200. Looking for something custom...

    [QUOTE=cfm;324614]Sleeper - that keeps your oil temp down enough ? How long to you run at higher rpm at a time ? Normal water temp you ride in ?]

    It keeps the oil temp at 190-210* on 12-15 mile runs at 4,000 rpms. Water temp in engine at 140* intake water approx 80*.

    Racing WOT run back to back oil temp, Royal Purple or Mobil One, 220-225* back to back to back Nos passes.

    Ours is mounted in the bilge along the stringer so it's not seen anyway.

    Yeah I know what you mean about the ghetto thing, we have a $200 cooler on a nearly $ 20,000 engine........go figure.
