With the cooperation of our friends at EVOMS, SpeedTech is able to offer a special group buy on the EVOMS underdrive pulley for the 996TT and 997.1TT (fits all model turbos/GT2's from 2001-2009 6-spd and tiptronic transmissions).

NOTE: The group buy is over - but we have regular inventory available for shipping - call for 6speed pricing.

Here is some information about the pulley - The Evolution MotorSports ClubSport crank pulley upgrade is almost 75% lighter (220g vs. 860g) than the stock steel pulley. The reduction of weight improves throttle response and overall engine performance. The EVOMS pulley is also slightly smaller (same size as the OEM GT3 pulley) which under drives the accessories, thus reduces parasitic drag and further improves engine efficiency. The pulley is precision balanced to within less than .1 gram to insure super smooth running, along with the quick revs.

Some additional information:

• Real world tested on a wide range of vehicles: from 420 HP street cars to 1000 HP race cars @ 9000 RPMS
• CNC Machined from 6061-T6 aluminum (OEM pulley is steel)
• Anodized black to preserve / seal the aluminum and retain an OEM appearance
• Reduced rotating weight: EVOMS CS pulley is ~75% lighter than the OEM steel pulley
• 50% more surface area where the pulley mates with the snout of the crankshaft (See photo below)
• Underdrives the engine accessories at the OEM specified range. ~15% (Same as the OEM GT3/RS)
• Incorporates machined OEM timing marks on the pulley
• Balanced within less than .1 gram
• Lifetime warranty – Original purchaser
