    Additional sump baffling

    Any of you 400-500bhp boys done extra work on the sump regards baffles and such to prevent oil surge and to ensure the pickup-pipe is always in oil ?

    Its standard practice when modifying engines, but I've never studied the S2 engines sump to see what amount of baffling is in there from zee factory.

    Anybody BTDT ?

    I've done nothing on this.

    I will take some pics of the sump for you though - and the pick up and the baffle.

      Considering this is coming from Doug, what is "baffling" is that he hasn't messed with it.

      SORRY. I couldn't stop myself.

        I was going to post about this subject a couple of months ago, i'd say its definately worth considering, i know integrales can suffer from oil starvation problems due to the high cornering forces they produce, and ive read a few horror stories from owners who have wrecked their engines due to the oil level not being on the maximum .
        I would say its only maybe a problem if you let the oil level drop.
        maybe worth asking dialynx as the produce monster hp engines, but they are probably dry sumped anyway

          Here is a picture. I don't know if it is good or bad due to never seeing a proper baffled sump.

            Its baffled alright - not as excessively as some I've seen though - but definitely better than nothing. Maybe some existing baffles could be made higher - subject to clearance with moving parts of course. Suggest you get expert advice - I just thought I'd offer up the question before you, Mark and others got past the point of no return... Though in saying that its relatively easy to remove the sump at any time for such a mod.

              They can't really be made much higher as there is the splash guard(can't remember the name) that goes over the top and it is contoured down into the sump - follwing the crank profile.

              I have more pics of it at home.

              The sump takes longer than you think to take off - BTDT.
