Finally, a viscous performance damper for the NA/NB Miata. We've seen the "lightweight" bonded balancer come and go without much luck or proven results. Even in theory, they weren't good solutions for those of us pushing these engines beyond their intentions. Protect your engine. Modifications can compromise your stock harmonic balancer.

Since Fluidamper is a trusted name in motorsports, we're going to skip their already acquired credibility and talk about the fact that this is NASA and SCCA compliant! That's right, you can now properly protect your beloved track dedicated investment without breaking the rules. 

This features a 10% underdrive water pump drive pulley designed to prevent cavitation and overheating at high rpm.  As with any "propeller" your water pump impeller can only be efficient in a small window. This makes sure you stay closer to the peak efficiency of that impeller, when it matters most. Installation compatible with OE and Mazdaspeed trigger wheels and does not require loosening crankshaft bolt. Four bolt mounting interface allows for continued NASA and SCCA compliance. Damper includes recommended grade 12.9 M6x16mm fasteners. SFI 18.1

As mentioned above, this damper does NOT require the removal of your crank bolt. We offer them as add on pieces since this will likely be one of those "while you're in there" jobs and potentially a good time to knock out your timing or water pump services.

    Noticed improvement immediately. The engine has less vibration and install is basically plug-and-play. Shipping dispatched immediately.

    install info out of date

    Posted by Bradley McCarthy on Mar 5th 2022

    installation information for this is out of date and missing important details. firstly, installation most definitely requires the removal of the large bolt (as stated right in fluidamprs install instructions). also, and this bit is missing in fluidamprs instructions as well, if you are installing on a car that does NOT use a timing wheel (ie, 1.6 long nose) you need to put a spacer where the wheel would go or your timing belt will run off the front of the timing gear. i used the plate that came off the stock pulley. otherwise works great!
