ATI Super Damper, SFI approved for street and race applications. Built specifically for high-performance applications, the ATI Super Damper provides balanced dampening of torsional crankshaft vibrations at all RPM while overdriving the supercharger to increase supercharger boost levels when combined with custom tuning that is needed to disable the factory overboost controls.
The patented ATI Super Damper is the only damper designed exclusively for high performance engines.
- Eliminates torsional crankshaft vibrations
- Exceeds SFI 18.1 specs
- Laser engraved 360 timing marks
- Black zinc chromate finished
Inner and outer shells are aluminum or steel to contain the steel inertia weight. The inertia weight has eight computer-machined grooves to retain the proper durometer O-rings (installed at ATI and dyno tested for each application). O-ring life has been tested in Winston Cup competition over two million cycles and in drag racing engines for 10 years (exceeds SFI 18.1 specs). Units can be rebuilt by installing new O-rings. Shells have a black zinc chromate finish with computer-controlled, laser-engraved 360-degree timing marks.
PRODUCT NOTES:
On average, this overdrive pulley typically adds 2 to 2.5psi additional boost depending on blower application. Running a larger crank pulley helps prevent belt slip caused by use of small supercharger pulleys to achieve a desired boost level.
We've made the kit easy for you or your installer. Per Chrysler, if you remove the damper bolt, it requires you to replace the bolt. At HHP we use and recommend the stronger and reusable P1 S220 High Strength Crankshaft Bolt or the standard non-reusable 2018+ OEM MOPAR 06512335AA Crankshaft Bolt any time you remove your OEM crank bolt.
ONLY AT HHP! We add additional low profile installation hardware at no extra cost so that you do not need to shave the heads off your OEM Timing Cover Bolts.
The required correct length 10-Rib serpentine belt is available above for use with upper pulleys ranging from 2.75" to 3.35".
We strongly recommend the optional crank pinning kit as well since aftermarket dampers should never be run without pinning the crankshaft, unless you are using an aftermarket crankshaft with Keyway.
Use of this pulley requires custom PCM calibration/tuning, and HHP can easily provide this service for you.
