ATI Super Damper MINI Cooper S Crankshaft Pulley. Lately we have seen several stock Crank Pulleys or Harmonic Balancers on the 02-06 MINI
Cooper S R53 fail and come apart. Now there is a new choice rather than the OEM one that
failed, and this isn't a lightweight Aluminum pulley that has NO
dampening that will wear out your crank bearings. Helping your
engine last. ATI Racing designed this 5.5” damper for the Mini Cooper S engines to be the best around. This new design is a
direct replacement for the stock OEM Mini Cooper S
damper from 2002 through 2006. 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 has been machined to allow OEM serpentine belt
locations, and includes laser-etched timing marks.
Eliminates torsional crankshaft vibrations
Exceeds SFI 18.1 specs
Laser etched 360° timing marks
Black zinc chromate finished
This damper is slightly lighter than the OEM 05-06, and almost
2lbs lighter than the 02-04 crank pulley, and it will dampen better
than stock.
NEW OVERDRIVE WMW EXCLUSIVE
WMW Now offers a 2% Overdrive size. This will allow you to spin
the supercharger slightly faster without giving up the engine damper.
All the other oversized crank pulleys on the market do away with the
engine damper. This can cause extra wear on the bearings or oil pump
causing reduced engine life. See detailed picture below of a failed
stock pulley. Lightweight Hardware Option: WMW now offers the ATI Damper with Titanium bolts. For the real racer this is the ultimate as it will reduce the rotating weight of the pulley, but still be strong to keep it reliable.
WMW recommends replacing the crank bolt anytime it is removed. select it below. Every ATI Damper also includes the black longer bolt with 1/2 washer to install. This way you don't need an installer.
