Recently got to know Benzline carries crank pulley from Euro motorsports when installing piggy ECU. Damn itchy to try out. Downtime only 45mins. Heard they installed many. Any brudder here have this installed by them?

PMed.

Crank pulley free up rotational restriction due to light weight so engine revs easier and builds energy faster and better gas mileage.

The rule of thumb is that each pound of weight taken off the engines rotating assembly is worth approximately 2.7HP. The concept is that the crank is a parasite; it does not put power to the drivetrain but still requires the energy produced by the engine to rotate. When you reduce this parasitic weight, you release power that was previously used only for spinning the supercharger.

Since the crank pulley diameter is unchanged, they maintain exactly stock output levels so you need not worry about flat batteries or weak charging capabilities. Through extensive weight savings afforded by aluminum construction, power gains of up to 10% are expected.

To really reduce rotational mass and improve acceleration, use a lightweight supercharger pulley along with a lightened crank pulley (same diameter as stock crank pulley).

Hi stealth.. can i know where u have installed the light weight crank pulley.

Thanks
