Product Detail |
 |
As used on Turner Motorsports Project E46 M3 street car these are engineered not only to be the best pulley kits on the market, but to provide the best compromise between performance and reliability! Specifically, we have designed these "stock looking" pulleys to underdrive the water pump, power steering pump and alternator. Adding these is like getting FREE HORSEPOWER - there are no downsides and underdriving each of these accessories has been proven safe through years of on and off-track use. We do not believe it is safe to change the crankshaft pulley due to the potential harm to the crankshaft. These kits provide 10%-20% overall reduction in driving your car's systems and have been dyno tested with a gain of 10hp on the E46 M3.
Kit includes water pump, power steering, alternator pulleys and belt. The T-6061 hard anodized aluminum pulleys account for a 10 to 20-percent decrease in accessory speeds, reducing the load on the engine.
