$600.00

In stock

SKU: 608

The RSS Harmonically Dampened Underdrive Pulley is ideal for engines that are running light weight flywheels, engines that are built - bored/stroked, and engines that are driven hard. Porsche used a harmonically dampened crankshaft pulley on all 997 3.8 models, so we recommend them on all engines for both street and track use.

Offers improved HP & TQ by reducing drag from the power steering pump, A/C, water pump and alternator without detrimental effects on said ancillary systems. Dampens/reduces internal engine harmonics for improved engine performance, efficiency and longevity.

Fits on all Porsche Boxster, Cayman, and 911 engines (986, 996, 987, 997 models) from 1997 through 2008. Does not fit 2.9L (multi hole crank pulley pattern), 9A1/MA1 and later DFI engines, or GT2, GT3 and Turbo Mezger engines.

Installation tool (wrench) and new OEM Pulley Washer included:

Dyno Image shows HP & TQ gain on 2005 997.1 Carrera S:
