Underdrive Crank Pulley

The Unorthodox Racing Underdrive Crank Pulley is a performance-enhancing component designed for J-Series V6 engines. This pulley is CAD designed and CNC machined from 6061 Aluminum billet, ensuring durability and a precise fit. The primary gains from this pulley are achieved through significant weight loss, accounting for 80-85% of the overall performance increase. An additional 15-20% of the gains come from underdriving the vehicle's accessories. Unorthodox Racing emphasizes a balanced approach, ensuring that critical systems like the charging system, air conditioning, power steering, and water pump continue to operate effectively at sufficient speeds for daily driving. The underdriving is primarily managed by the crank pulley itself, maximizing weight loss at the crank where horsepower gains are most impactful. Features of this underdrive crank pulley include real horsepower and torque gains across the entire RPM range, making it one of the market's best HP/Torque per dollar value propositions. It boasts a broad application range and has been tested in real-world conditions from street use to racing. The pulley offers better-than-OEM belt fitment and alignment. Accessory pulleys are also available separately for many applications. Dyno testing has shown gains of +9 whp / +20 tq on a 2010 Accord V6. This pulley is compatible with a wide range of Acura and Honda models, including the Acura MDX (2003-2014), RL (2014-2018), TL (2004-2014), TLX (2015-2020), TSX (2009-2014), Honda Accord/Crosstour (2003-2017), Odyssey (2003-2018), Pilot (2003-2018), Ridgeline (2006-2018), and Saturn Vue (2004-2007).
