    Pump for W2A intercooler

    Just looking for recommendations for a new pump currently running very early davies craig electric pump has to push coolant about 2.5mtrs to radiator mounted behind cab(dual cab ute)im think maybe just going one off the newer cast alloy DC pumps,but interested to see what others have/are using, all hose 3/4".

    The pump of choice for the intercooler in my circles is an OEM Bosch one which is used on the AMG E55.

    Bosch p/n 0 392 022 010, Merc p/n 000-500-03-86

    You can also buy the pigtail & connector to suit from Merc.

    p/n 000-540-24-05 for the cables (need 2x)
    p/n 230-540-00-81 for the connector (need 1x)
    Jaguar XJR, Freelander 2 HSE

    Yea I used one of those Bosch ones on a supercharged mx5 I had. Was fine. People also hook them up to a 12v battery on camping trips for a cheap and easy shower with a bucket of water, some hose and a shower head. /useless info.

    My advice with w2a is to go with a decent flow rate pump or if it is a budget build go with something halfway decent that won't be the bottleneck and skimp with the other bits. You can always under-drive or even turn off the pump with some controls in the cabin when you don't need the full flow.

    I've got a mr2 with mostly 3/4 lines (like you) and 1" feed to the pump and use a 20 gpm pump.

    I have been using a Bosch Cobra in a Datto 1600 boot mounted pump. All good no problems. Quiet enough. Standard fitment on supercharged Ford Mustang and others . Will also need the pigtail and connector. Check out frozenboost.com for these and other kits.

    So im gathering that the bosch 0392022002 would be the goods, what i have now is this(of unknown condition)
    http://www.ebay.com.au/itm/Davies-Cr...oAAOSwA3dYT14~
    the flow rates are a mile apart i believe the one above is the cobra, research and PF are hinting that bigger is not always better!!
    at the moment the DC pump is quite high in the engine bay, im thinking of mounting pump down low out the back pulling straight out bottom exchanger/radiator hose directly to intercooler, i do have a bleeder at the highest point of intercooler
    This pump will just run fulltime and i may have the fan on the exchanger temperature switched (if i can work out how to turn on at only about 50c)
