What is a Performance Pulley?

Performance pulleys are commonly called under-drive pulleys and v-velt pulleys. But what does it exactly do? It works by by driving a vehicle’s accessories at a slower rate than previously set factory settings. The controlled speed means the engine spends less effort spinning the performance pulleys and the other gadgets attached to it.

The reduced workload on the engine translates to extra power given to driving the wheels forward. Many car enthusiasts attest to the engine boost the performance pulleys provide. This mechanism has now become a standard fixture in modified and even in stock cars.

What some people don’t know is that a performance pulley can free up to 15 hp (horsepower) and cost just a couple of hundred bucks or less. Most after-market auto parts dealers carry a wide variety of under drive pulley configurations which allow you, the car owner to run the option to tweak or alter the amount of under drive built into the pulley set.

Fun Fact: it’s a very handy feature for those who want to run a full-speed alternator while still getting gains through the power steering and air conditioning pulleys.

What’s The Beneficial Purpose Of A Performance Pulley?

As you already know, there are numerous ways to enhance your vehicle’s performance on the public or private road. If you’re a car expert then you already know one way is to replace the stock pulleys with performance pulleys. The under-drive pulley is designed to drive certain accessory systems at a slower rate than the default, factory-set pace.

Basically, what this workload reduction does is allowing the engine to devote more energy to produce more torque (torque means the amount of “turning power” you have/ a better measurement of how quickly your car will accelerate, while horsepower (relative to weight) is a better measure of your car’s top speed) and horsepower.

If you’re lucky enough to have a car equipped with a supercharger then these pulleys work better and guarantee more significant power gains for vehicles that use forced air induction.

Some things you may or may not know is that performance pulleys are actually longer lasting than your ordinary stock pulley, it helps the engine produce more power and the obvious (for some of you): it’s compatible for use with the air-conditioning, power steering, and engine cooling systems. So if you want more horsepower and torque (aka a faster driving car) then a performance pulley would definitely benefit your car!
