Porsche M96 / M97 Underdrive Pulley Kit

The Boxster/Cayman/Carrera platform has a tendency to overwork and overheat the Power Steering pump to the point that some of the lines and even plastic fluid reservoir have been known to melt! Cars that are Autocrossed or Tracked suffer the most from this malady. One of the simplest and most effective solutions is to install a smaller crankshaft pulley known as an <strong>underdrive pulley</strong>, because it underdrives the secondary systems (A/C, Alternator and Power Steering). There are no negative issues with cooling, charging or steering, but there’s an upside: the engine will regain back about 5-7 HP!

TRS Motorsports 4 inch under drive crankshaft pulley kit includes pulley, drive belt (with or without A/C) and new bolt. Our pulley is CNC machined from 6061-T6 aluminum and is anodized gold. Updating your car with our under drive pulley improves horsepower and torque while reducing parasitic drag from the alternator, power steering pump and water pump. Moreover, our pulley is also Spec Boxster legal.
