jackb_ms Posted February 11, 2010 Share Posted February 11, 2010 Hello Question for the POBC. What is the difference, apart from the colour, between a blue and gold oil pump for a dry sump from CC? Which part are interchangeable? Cheers Jack Emily, The Very Yellow 21 Edited by - jackb_ms on 11 Feb 2010 15:56:38 Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted February 11, 2010 Area Representative Share Posted February 11, 2010 As I understand it, the gold pump has a higher capacity than the purple one. I'm not sure, but I don't think that they are interchangable. Link to comment Share on other sites More sharing options...
shn7 Posted February 11, 2010 Share Posted February 11, 2010 *arrowup*What he said . Having said that I've run two car for road and track use with purple pump and not encountered any problems. IIRC The change was made by CC after some SLR racers (on slicks) suffer oil starvation problems. Steve.

Team Escargot Posted February 11, 2010 Share Posted February 11, 2010 As Steve said there were some problems with the blue pump Gold is now the standard (has been for last 3 years I think) I am told they are interchangable Nick Link to comment Share on other sites More sharing options...
shn7 Posted February 11, 2010 Share Posted February 11, 2010 Gold pump has been around a lot more than 3 years. Probably as far back as 2000 at a guess. And unless you're colour blind it's purple not blue 😬 😬 Steve. Not forgetting Percy the Polar Bear who recommends Puddle Pet Care Link to comment Share on other sites More sharing options...
jackb_ms Posted February 11, 2010 Author Share Posted February 11, 2010 I am colour blind 😬 Is the polley interchangeable? the coolant hose is a bit too close for confort. Jack Emily, The Very Yellow 21 Link to comment Share on other sites More sharing options...
Rob Walker Posted February 12, 2010 Share Posted February 12, 2010 The purple pump is a vane pump the gold pump is a gear pump. The gold pump was introduced as it is more efficient at high revs, in say the K R500 application or R400 race cars. No it is not advisable to run the same pulley as the purple pump runs a big 100mm dia pulley to gear down the shaft speed of the pump to reduce cavitation, the gold pump runs a smaller pulley. Rob  Link to comment Share on other sites More sharing options...
