Just got my nst lightweight crank pulley installed, has anyone used this? Thoughts?

 

Nice! Did you notice any difference in the way the car drives?

 

Not sure if its just a placebo effect but the throttle response is a lot quicker. However I am hearing some sort of vibrating noise though.

So I need to figure that out.

Maybe you have some sort of idea on what's causing it.

Aside from that, all in all I'm happy with it, all I'm lacking now is to to get the car tuned.

Cheers,

 

Not sure what that vibrating noise could be. I never had it after having the pulley installed. Glad you like it but make sure you have that vibrating noise taken care of. Good luck!

Nice looking rotors and brake pads btw.

 

Crank vibrations are for sure NOT good. I wouldn't use anything other than the OEM piece as destroying your drivetrain to gain a tad of acceleration is just silly. Aftermarket crank pulley's that have not been tested properly have been know to cause major engine damage. Lots of stories on the web about this.

My vote is remove it. Not worth the expensive price of short or long term engine damage. Nor does that company have very good product reviews in general. Fluid dampners are where it's at if you want a real upgrade.
