I was browsing around in the UR website and they have a Pulley kit for the S2k, Also Ricks has a Pulley set!

Do you think this will free up or give some extra WHP to a FI or even a NA S2k?

Thanks in advance Guys!

 

Theoretically they should- assuming they are designed correctly. I have not seen any dynographs proving an increase in power though.

 

I put the ricks pulleys on because I know they make quality stuff... and if anything, they look nice, and that 1.5 lbs less that I'm carrying around

 

not really sure if it would actually give more horsepower or torque, but, theoretically, should increase throttle response with the lesser weight and lesser cintrifugal force required to spin the pulleys.. i think?

 

Uhmmmmmm i used to own a 99 Civic Si and i bought the UR Under Drive Crank pulley and i felt the difference right away!

I know they dont have a Crank pulley for the S2k but i think it should free some WHP

 

remember these are not underdriven just simply a few ounces lighter per pulley.
