Currently having a motor built for about 500HP and was wondering if this part would be helpful or if it isn't needed for me. Car is a weekend car with the occasional drag, nothing crazy. Thanks.

 

if your not running a balance shaft, i would recommend it.

 

I am not running a balance shaft...

 

I am running a balance shaft but chose to run a Fluidampr. A member on here did a pretty simple test on the benefits, and it does dampen vibrations. I wanted a smoother running engine so I chose this part, and I like it.

I also ordered ARP hardware because there's been a couple cases where the stock bolts sheared off.

 

ARP hardware for the 4 pulley bolts?

 

Yup.

 

I got the Fluidampr and ARP bolts from JNZ Tuning.
