exciting NEW concept offers more available engine power, better mpg, improved
cooling with quicker warm up and longer engine life.
It is supplied in kit form to replace existing belt driven water pumps.
Use with an adjustable electronic controller which supplies exact voltage to govern water pump speed to achieve desired cooling requirements.
Owners of older cars with troublesome original pumps have also achieved new found cooling reliability.
The existing belt driven pump is inefficient in that to allow sufficient circulation at low speed, the flow generated at medium to high speeds is not required and is wasteful of engine power as is the energy required to speed up a mass of water through a restrictive radiator during hard acceleration. Water circulation ceases on turn off and engines are often "cooked" by switching off after a high speed run.
The water pump may be fitted in any location where it can be connected into the bottom hose, adapters are supplied to suit various hose diameters.
It is not necessary to completely remove the existing water pump. The pump pulley can be disconnected and a shorter belt used, the pump will then idle and offer no resistance to flow. Alternatively the old impeller may be removed from the shaft.

electronic controller is mounted under the dashboard where adjustment dial
reached, all wiring and connectors are supplied. The temperature sensor is
a thin flexible rod which is inserted into the existing thermostat housing,
thermostat itself is removed. Wiring on battery side of ignition switch will
allow pump to run on. Comprehensive instructions & wiring diagrams are
For short duration racing where no alternator is used and current used is of no significance an adjustable thermostatic or on/off switch may be used.
For serious competitors the ability to tailor flow will enable redesign of the entire cooling system resulting in smaller radiators with obvious advantages.
For all competitors the time wasted in taping up radiators to achieve correct temperatures will be a thing of the past.
