As it's lighter and more compact than the Mocal/Tilton one. I believe this is the cooler pump that a lot of current BMW models use on their differentials. I use this pump, controlled by my ECU to circulate my gearbox oil through a Mocal Laminova cooler dependent on gearbox temperature and throttle position.

Temp is going to be hot, this is to pump oil back from a holset turbo that is mounted at the rear of a V8 Commy.

Aah, in which case the Mocal unit is probably better :)

yes, as it is rated for high temps. Poss should have added that small amount of info in my initial post. That VDO one does look interesting thou.

you should only let oil drain back from a turbo.make the drain minimum of twice the diameter of the supply and run it direct to the sump ABOVE the oil level in the sump. if you suck it out you can damage the turbo bearings and pull air past the seals.
bill-robinson - the oil return will be higher than where the turbo is mounted, hence the reason for needing a pump.

ord, great thanks, not a bad price, just need to check the specs. At least this gives me someone in NZ now - a stockest.

does height matter!, I'd be more concerned about seal lips being biased in one direction ie against oil pressure, if you put a vacuum in there ( pump after bearings) and any air sucks through those seals ( as it will - they're designed to stop pressure against not air under from the other direction) you'll so quickly have shot bearings it will make your head spin - but not the turbo's - well not for long anyway put your pump before the turbo's, and your oil exhaust can run up to wherever - any residual pressure is minimal, and desirable - bearings are flooded at start too just got to make sure you spool down properly - excess heat can build in a turbo as it winds down the timed shutoff - check your turbo details and fit gauges, shut down manually at appropriate temp

Describe the oil system layout please. where does the oil to the turbo come from! what size pipe is it! where is the turbo mounted, andwhy there! where does the drain return to! what size pipe is it! ALL the ifo not just dribs and drabs. Then you may get sensible help.
