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.
