Crank pulleys, attached to the outside of the crankshaft, are the source of power for a car’s accessories. The alternator, power steering, water pump, and air conditioner are all belt driven units, attached to the crank pulley, that use horsepower from an engine to provide their own services. Underdrive pulley systems increase an engine’s horsepower by reducing the power required to drive the external engine accessories. By replacing factory pulleys with carefully resized units, the accessories are slowed enough so that their performance does not suffer, but just enough so that more horsepower is sent to the wheels and put to the ground. Where horsepower should be!

Normally, underdrive pulleys like the units found at NonStopTuning will increase engine output by 8 to 15 horsepower! This increase results in quarter-mile time improvements of .2 to .25 seconds, easily making this modification one of the best “bang for your buck” modifications for any sport compact car or truck.

Another great benefit in replacing factory pulleys with underdrive units is reduced weight. Factory units, also referred to as OEM, are generally constructed from steel or cast iron. Pulley systems like those found at NST are constructed of aircraft quality aluminum, making them extremely durable while at the same time much lighter than their steel counterparts. This weight reduction results in less rotating mass on the engine’s crankshaft which drastically increases the engine’s ability to rev up to speed more quickly.

NonStopTuning was established in 2005 and set out to drive performance trends for sport compact cars; to design and market high performance products that large automobile manufacturers could, but would not produce.

NST is committed to marketing products of exceptional quality, craftsmanship, and reliability. A dedication to monitoring consumer needs and feedback regarding quality of materials, visual appearance, and most importantly performance, is the driving force behind the success of NST. Products found at NST are not only offered at a great value, but are also designed to be very user-friendly and easy to install.

The NST brand is now well established and our commitment to excellent research and development has put our products to the test in drag racing, road racing, and drift competitions. NST has placed several products to the test in competing cars in these fields, and has an ongoing commitment to Research & Development using our constantly expanding race team.

We realize that as a consumer you have an infinite array of available products to choose from, and we sincerely appreciate your support of our brand.

From all of us at NST, good luck and have fun with all your project cars!
