I spent a long time on the phone today with Pace products about their ZX12R dry sump system. it really is a very neat bit of kit. Apparently you remove the existing water pump and oil pump assembly from the side of the engine and simply slide the new 3 stage (2 scavenge and 1 pressure stage) dry sump pump into the existing housing. The pump is even driven by the engine’s existing oil pump drive shaft so no external drive belts are required. All that remains is to remove and blank off the existing pressure relief\control valve and dial in the required pressure using the adjuster on the pump. Of course you lose the mechanical water pump, but I had been pre warned that this was the case and ordered and EWC electric one via a BEC list bulk buy back in November. The dry sump pump is quoted as outputting 80+ PSI at full chat and 25+ at idle. Needless to say I ordered one and hopefully it will be with me by the end of February.
Pace also advised that a secondary benefit of having the oil reservoir in a remote tank rather than in the sump is that oil overheating is not a problem so I’ve decided not to fit an air\oil cooler and see how it goes temperature wise.
Only one thing left to do and that’s find a suitable location, size and mounting point for the dry sump tank and then order an appropriate one from Pace. I must remember to ask them to put in a 1\8th NPT boss for the Digidash’s oil temp sensor. Talking of which…….
