Agency Power has a lightweight crank pulley for Mitsubishi’s Evo X 4B11 motor. This lightweight design of the pulley allows quicker throttle response , improved rev matching, and more for the serious performance driver, or daily driven Evo X. This pulley also retains your OEM belt, being a true direct bolt on product.

The lightweight crank pulley is made out of fully CNC machined 6061 aluminum, and available in Black or silver. A widely known fact in the performance scene is less weight equates to better. Agency Power didn’t come short on this reducing the weight of the pulley from the OEM weight of 4.0lbs to 1.0lbs. If your looking for a upgrade to increase performance, at a great price, and fairly easy install look no further. Agency Power’s AP-CZ4A-130 is your answer.


Anyone have it? Does it make the throttle respond better? Any noticeable differences or changes?

 

I had a UR version of one of these on a 350z, biggest waste of cash and my effort fitting it, I didn't notcice any change.............interested to see if the it works on the 4B11T

 

Yeah, I'm wondering as well. I mean less rotating mass for the 2L would seem to help. I mean the principle is the same as a light flywheel. Less weight on the crank, produces less rotating mass, thus less parasitic drag, thus better free rev and loosen up a hp or 2.


Since I doubt you would see much help with anything over 3L since they produce more torque in the low end.

 

I've always been leery of these. Getting rid of the harmonic dampener seems like a bad idea IMO, especially if you only gain so little power. The risk outweighs to gain IMO.

 

Im reviving this thread instead of creating a new one, anyone running this pulley?

 

QFT.

Really nothing but a waste of money, time.

 

I think it was established as a waste of money mod.

Much like non-O2 downpipe, larger turbo outlet, and blinker fluid.

No wonder they are so cheap
