Essex Rotaary Lightweight Under Drive 4 Pulley Kit for FD3s

4 Pulley kit Including Belts ideally suited for your RX-7 FD3s
Essex Rotary brings you this new lightweight under drive pulley Kit replaces all three main pulleys (Main Eccentyric Shaft Pulley, Alternator and Water Pump Pulleys) plus the Power Steering Pump Pulley, 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 belts (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 item is normally in stock however please allow up to 21 days for delivery of your kit if we are out of stock.
