Default Re: LET Motorsports Pulley Special!!
Thanks for the reply, but unfortunately I am still slightly confused. It’s understood that the harmonic balancer is internally dampened and balanced and it appears to be a Fluidampr, which is great news to me. But my question comes when breaking the harmonic balancer / blower drive pulley assembly down one more level:

...Is the grooved blower drive pulley, which is cast/machined separately and bolted to the harmonic balancer with 6 bolts, balanced separately prior to its attachment to the BALANCER?

...Or is the complete assembly of harmonic balancer and pulley RE-balanced as an ASSEMBLED pair once they are bolted to each other?

…Thus making the entire assembly 100% neutral balanced and not just the harmonic balancer portion of the unit.

I just need to be clear, as I’ll be balancing mine after purchase, if need be

Thanks again for your help

the pulley is both internally dampened and neutral balanced prior to attaching to the crank shaft...

the 185mm pulley (the biggest we offer) spins the blower at 19,250rpms, very safe buffer zone from the max rpm of the blower...

please let me know if you have any other questions...thanks!
