Wow what a difference.
I have a hybrid, self-built EJ Subaru motor with a lightweight flywheel and a Perrin lightweight pulley (because I liked shiny things). After replacing the Perrin with the Fluidampr, the engine feels much more stable and revs happier. Does not die and the shudders are almost completely gone! I would daily it if it wasn't a track car. Bravo! Tips: Soak in hot water for 15 minutes before installing. Torque to spec.

Not very much difference on a stock car
installed on an otherwise stock 2006 STI at the time of a new timing belt kit. The car feels maybe slightly less buzzy/harsh at higher RPMs. maybe I would notice more of a difference if my car were more heavily modified. Also kind of annoying that the bolt pattern is different than the OE pulley, which means I literally have no more use for my $100 Company 23 wrench unless I modify it

Got rid of false knock. Engine feels smoother. Put this on after break in miles on my new build. Got tuned at 318/350. New injectors up next!
