Bottom line is - you want a damper that is effective at multiple RPM ranges! You may have seen dampers that appear to be machined copies of the OEM pulley, these are static weighted, single striped and BONDED dampers that are only capable of being tuned for a single RPM range.
The ATI Torsional Super Damper® - the unconventional, unbonded elastomer Super Damper™ that is actually 2 dampers in 1 diameter.
In contrast, the ATI Super Damper employs a combination of O-rings and a unique, full-captured inertia ring to dampen harmful crankshaft vibrations. This configuration allows the damper to actually absorb crankshaft harmonics over a wide rpm range. It is not uncommon to find a Super Damper on race engines exceeding 9,000 rpm.
- The 96-05 Miata is equipped with a trigger wheel that unfortunately can not be installed on your new ATI Damper - To solve this problem we have produced our own trigger wheel that can easily be installed to the ATI damper prior to installation.
- Can be used on a long nose 1.6 engine when used with the 1.8 water pump and alternator pulleys.
- Not compatible with short nose crank 1.6
- If using a 1.6L you'll need to change your water pump and alternator pulley to a 1.8 configuration
ATI has designed a 5.5” damper - for the '94 - '05 Mazda Miata engine for high horsepower street & race use. This new design is a direct replacement for the stock OEM damper. The heart of this unit is the tried and true “damper within a damper” design that has put ATI ahead of the rest. The outer shell is machined to utilize the factory serpentine belt set-up
No trigger wheel: For 1.6 or 1.8 engine using CAS
Modified 4 tooth trigger wheel: For 96-05 using OEM triggering or aftermarket ECU that supports OE wheels.
Haven't installed it yet but I can tell it's superb quality and the price is well worth it if you're pushing big power.
