Supercharger Super Dampers®
The ATI Supercharger Super Dampers
places the powerful protection of our Super Damper inside
the crankshaft blower pulley! Why bother with an additional
blower pulley that bolts to your stock harmonic balancer? The ATI Supercharger Super Damper features external
belt drives for virtually any type of blower belt, and
eliminates the need for separate crank mounted blower
pulleys.
Crank hubs are available for all engines and are available
with 25 tooth x 20mm 8mm HTD drive pulleys machined
in the hub for dry sump or fuel pump drives between
the damper / blower pulley and the engine.
Most hubs have dual keyways and are available in custom
lengths for all cam belt drive set-ups from Jesel, Danny
B, and Comp Cams. Numerous pulley offsets are available
to keep the blower drive as close to the engine as possible
to reduce the bending moment to the crankshaft nose.

[3] Hub #916566A has increased wall thickness
& two 3/16” keyways for 4-bolt supercharged applications.
Requires seal #973131. This hub is bored straight through
with no counterbore for OEM crankshafts with the keyway 1”
back. It is intended for aftermarket cranks or “engine
builder hone to fit” full length keys. Request counterbore
if using an OEM crankshaft. For undersized hub, order part
#916566AU.
[4] 1994 and 1995 have clearance issues with the rack. Part
#918910 is 50 oz. in.
[5] Must grind and epoxy later model block’s crank sensor
area to clear the back outer diameter of the damper.
[11] 1994 & 1995 cars use a 3.35” long hub with
an 11 o’clock keyway (custom item-not in stock). The
rack for these cars is under the oil pan and nowhere near
the damper. Part #918910 is 50 oz. in.
ATI stocks all HTD pulleys. Please consult
an ATI sales technician.
