CRAIGR Posted November 4, 2013 Posted November 4, 2013 Anyone got an accusump lurking around unloved. Please pm me if you have
CRAIGR Posted November 4, 2013 Author Posted November 4, 2013 Thought you'd have half a dozen stashed away in your warehouse somewhere guv
CRAIGR Posted November 4, 2013 Author Posted November 4, 2013 Been told its dry sump or one of these on the old datsun engine or "POP"
SteveD Posted November 4, 2013 Posted November 4, 2013 pile of pooh thats made to mask a problem not cure it
stu999 Posted November 4, 2013 Posted November 4, 2013 Absolutely no chance of modifying wet sump? As Steve says, Accusump merely 'sticks a plaster' over the problem of oil surge...
CRAIGR Posted November 4, 2013 Author Posted November 4, 2013 I can get a baffled high capacity sump which would cure any sideways surge but apparently they can lose oil pressure under acceleration also
stu999 Posted November 4, 2013 Posted November 4, 2013 Knowing where the weakspot is is half the battle. Can more walls, trapdoors etc not be added to cure the problem? Even proprietary sumps can nearly always be improved upon with a little thought... Any pics of the wet sump???
CRAIGR Posted November 4, 2013 Author Posted November 4, 2013 This would be the type of thing which remains the same depth as original. http://www.ebay.co.uk/itm/TOMEI-OIL-PAN-RACE-SUMP-HIGH-VOLUME-S13-S14-S15-SILVIA-200SX-180SX-SR20DET-SR20-/200881245023?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2ec5748b5f#ht_3512wt_1328
stu999 Posted November 4, 2013 Posted November 4, 2013 Well that one wouldn't take much to improve it at all if that piccy is anything to go by...no wonder it suffers oil surge! No where near enough baffling and pick up pipe shrouding, especially for something like a Westfield...
CRAIGR Posted November 4, 2013 Author Posted November 4, 2013 Sorry Stu perhaps that was a bit misleading. This is a complete standard sump set up and it replaces the lower part (front left) only. http://www.ebay.co.uk/itm/Nissan-200SX-S14-S14A-SR20DET-Complete-oil-sump-set-/281110770546?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item417381f372#ht_1822wt_1091
Nick Algar - Competition Secretary Posted November 4, 2013 Posted November 4, 2013 Craig, I have used an Accusump on a race car because we could not get enough room to fit a normal dry sump system. It got rid of the oil surge problem which that car had ( DJ Firehawk) but has already be said it's really only hiding a problem as it's an accumulator. I was using the electric valve one, which I think was better as it takes a while to recharge, which means that once oil pressure has dropped away it goes back into the engine first. Have tried one with a mechanical straight through valve and I felt that put too much straight back into the sump rather than the engine. So use one if you want, but just be aware of their limitations. They are certainly a easy cheap solution, but if I used another one I would always data log it, to make sure it's working everywhere on the track. For example I never took the DJ to Mallory Park as I knew Gerrards would kill the engine. Hope that helps.
