Did you know that your BMW can make more power? 11 more HP to be exact - the idea of the Turner Motorsport pulley is simple. The less effort that your engine puts into running your accessories like your water pump, the power steering system, or your alternator etc, the more of that power can be put elsewhere - like your wheels. The way this is done is by reducing the rotation of the pulleys by as much as 10-20%! The end result is more horsepower at your disposal. Turner has done extensive testing (on and off the track), to ensure that the accessory systems still function as intended and without failure. These pulleys offer an excellent compromise of power gains, reliability, and performance. PS: These guys are aluminum so they’re not going to break like your OE plastic pulleys either.
