ATI Damper Pulley Kit

This is a kit for attaching the crank damper from ATI in US for “SR20DET engine.”
By attaching this damper, it absorbs the engine vibration and the durability of a crankshaft and a crank main metal improves.
Moreover, an exclusive pulley, in a set, turns into a slowdown pulley.

◊ Pulley ratio

• Crankshaft=1
• Water pump=0.87(normal 1.31)
• Alternator=1.79(normal 2.21)
• Power steering=0.93(normal 1.02)

It is the design which decelerates all rotations for a race.
This is for suppressing the cavitation and pump fault burden which are generated at the time of high rotation operation.

◊ The contents of a kit

• The 6 inch STEEL damper of ATI
• Crank hub (hub of combustion-proof and adhesion prevention)
• Crank pulley of duralumin (Double belt pulley / Hard alumite processing)
• Water pump pulley of duralumin (Hard alumite processing)
• Alternator Pulley of duralumin (Hard alumite processing)
• Power-steering pulley of duralumin (Hard alumite processing)
• Two special rib belts
• Bolts for attachment

* only for car without air conditioner.
* A little processing is needed at the time of install a normal fan.
