Fluidampr531101 Engine Damper

Installation was easy, installed with new belts looks really nice

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

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.

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!

Awesome part. Great price. Reasonable shipping. Satisfied customer.

I purchased this for my 2002 WRX I'm building. Runs much smoother. Made from quality materials.

Smooth

It's the kind of thing you dont really notice.
