Anyone have this installed?

It looks like it weighs less than the fluidampr and stock pieces-but obviously more than the UR ones.

For those that have the UR pulleys installed (stock size or underdrive)--are you pleased with them?

thx!

 

The fluidampr will overdrive vs stock sized crank pullies.

 

I know the fuildampr weighs a little more than stock, but if it is stock diameter, then how will it overdrive?

 

It's not a stock diameter. The Fluidampr main crank groove is slighter larger so it would overdrive a supercharger and other accessories.

 

So there is no real benefit to it unless you are F/I?

 

It should be a harmonic crank pulley and take away vibrations and what not from the crank. Lighter than stock - not by much, better piece - probably yes. If you were to put this on a supercharger you would make more boost with the same size sc pulley vs stock, just like using an underdrive on a sc pulley would make less.

 

ahhh. I see..very good to know..thanks rookie!
