Essex Rotary brings you our new lightweight under drive pulley Kit replaces all three pulleys, Main Crank Pulley plus Alternator and Water Pump Pulleys reducing the potential for Water Pump cavitation and over working of the Alternator at the high RPM ranges the Rotary Engine can operate at.

These Lightweight Pulleys are CNC machined from super light but extremely strong 6061-T6 Aluminium Alloy. reducing rotational weight from the crank and associated ancillaries will theoretically frees up horsepower normally used to turn the heavier pulleys and ancillaries (though Essex Rotary make no claim to proven HP gains when using under drive kits)

Cavitation

Cavitation is a process where by your water pump impeller acts like a “whisk” at high RPM beating air bubbles in to the coolant mixture, this process dramatically reduces coolant efficiency as the increasing cavitation effect reduces coolant flow around the engine.

Each kit comes with 2 new alternator/water pump and air conditioning drive belts made by Gates to suit your new setup as the OEM size belts will no longer fit.

This 3 piece kit has the same size water pump pulley as our 2 piece kit however the alternator pulley is slightly smaller in overall diameter.

This item is normally in stock however please allow up to 21 days for delivery of your kit if we are out of stock.
