CFM Underdrive Pulley Kit for '03-11 2.0/2.3L Duratec Focus

NOTE: This part must be professionally installed! Improper installation will result in severe engine damage!

If you're looking to wake up your Duratec with a solid 5-8whp then look no further! CFM Performance underdrive pulleys net additional engine torque and horsepower by reducing parasitic drag caused by belt-driven accessories but more importantly because of their lighter weight and reduction in rotational mass. These pulleys can also help to increase gas mileage but that is up to your right foot. CFM pulley kits are made from 6061 billet aluminum for strength and reduced weight over the factory pieces which are made from steel. They come anodized in black with a laser etched CFM Performance logo for a lasting finish and great looks.

underdrive pulley

I bought the pulleys and installed them at the shop just a little worried but everything went smooth. No over driving concerns with the alternator or any a/c issues. Actually i don't feel the sudden loss of power that the a/c compressor takes up as much. U can feel a little more accel too. water pump pulley gets bigger and may look like its gonna touch the belt going aroung the power steering pulley but no it doesn't. Good job guys.

I purchased this awesome piece of kit from cfm and fitted it to my fiesta ST(duratec 2L) which is already running cosworth cams, milltek exhaust system and mapped with Dreamscience. I noticed straight away that the throttle response was much better and the revs picked up smoothly. I did a dyno before and after and the gains for me were 7.2hp and 11nm gains on the wheels increase at high altitude in Johannesburg. Over all very happy with the build quality and an awesome product. Only negative was it requires a belt change as the stock one was too long after fitting the kit and this wasn't mentioned on this site.

In stalled it a couple days ago no belt squeal or any issues. Gave me a solid torque gain and definently improves responsiveness to the car. Did it myself really the instructions are overdone but great to follow if you don't know how to do an underdrive pulley. Took me about 10 minutes on a lift no timing issues what so ever timing light checked out prefect...Great product that takes a load off the crank the factory pulley is a heavy iron. This is a light steel....no charging problems just pure smooth responsiveness
