Supercharger with lightweight crank pulley....is it safe?
 

yes! As the title stated is it safe to install light weight crank pulley with HKS Super charger?

(I'm pretty sure it's fine)

LWCP is always a contentious topic around these parts. Aside from the usual arguments (omg harmonic damping!) I can't think of a reason why a SC would make things worse.

I run a Perrin Pulley with a Sprintex SC and have no issues.

More power = worse harmonics


(this is why SFI rated dampers are usually bigger and heavier for engines running lots of boost)

I've run with and without lwcp and chose to stay without. There really are no gains to be had, and it makes the car harder to drive on a daily basis.

To answer the op, don't bother.

Thank you for your inputs. I would put back the original LWCP just to be safe and worry free.

after lurking for many years on many forums, i avoid lightweight aluminum pulleys. so many fails from almost every manufacturer.

I have the exact setup shown in the pictire. Seems to run perfectly fine and no difference in drivability.
