Alfa Romeo / FIAT Light Weight Undersize Crank Pulley


We would like to introduce our lightweight undersize crank pulley for Alfa Romeo and Fiat.



It is smaller in diameter and 50% lighter than the OEM pulleys they replaced, hence maximize the reduction in weight on the crank. This reduction in weight reduces the moment of inertia allowing your engine to respond faster to throttle inputs and perform better at all RPMs.


On a standard 2.0TS 16V engine, we have managed to consistently gain more than 8bhp and 10Nm (see dyno charts below).


We fully maintain all accessory output minimums like air conditioning efficiency, power steering feel, and voltage even at idle with everything electrical on in the car. The combination of tight tolerances, precise quality control, perfect balance, and dramatic weight loss versus the stock pulley also reduces stress loads on your engine.
