Your Audi TT MK1's power steering, alternator and A/C are powered by a belt connected back to the crankshaft pulley. Spinning these pulleys draw precious horsepower from your engine. NEUSPEED's powertrain engineer, using sophisticated CAD software, performed a mass properties analysis of the crank pulley. The result is reduced parasitic drag on the engine and increased horsepower. This kit includes a new under-drive crankshaft and power steering pulley. Original equipment serpentine belt may be re-used.
Like our other NEUSPEED Power Pulleys, they are made from 6061 T6 aluminum and hard anodized for durability. Unlike color anodizing which is mostly cosmetic, hard anodizing builds up a hardened layer over the base material to prevent wear.
5 - 7 horsepower gain.
Designed and engineered Camarillo, California. Proudly manufactured in USA.
