At this stage of the fight, I was on the internet on a daily basis looking for what else I can do to my Golf 5 GTI. It is almost like an addiction, you get used to it and then want more. I came across something that Neuspeed makes. It is called “Power Pulley”. It replaces the standard crank pulley and they claim an increase in HP.
My first thoughts were how can a pulley give you an increase in HP. Doing some research on the subject it turned out doesn’t cause the engine to make more power but it makes more power available to the wheels.
So how do you get more power?
There are a few things that cause an increase in wheel power. The first thing is the Neuspeed pulley is a lot lighter than the standard pulley. The pulley is made from high-grade 6082-T6 aluminum where the standard pulley is steel with molded rubber.
The second reason you get more power to the wheels is the auxiliary units like your alternator and Aircon pump is spin at a slower rate. Which means there is less power being robbed from your engine. So at the end of the day you don’t make more power but power gets distributed to the wheel that normally would have been lost to the alternator and the air con pump.
Is it easy to install?
This was a really quick installation, with very little tools needed. And it looked great after it was installed. This is one of those parts that you wished was more visible when you open the bonnet of the car.
Is there a downside to fitting this pulley?
To answer this question yes. There is always a balance if you tip it one way you give up something else. In this case, what you give up is very small. You can feel that your air con is not as cold as it used to be, but sit cold enough that you have a pleasant commute. From a battery charging side, I never had any issues after fitting this kit. You may run into charging issues if you have a heavy sound system in your car. If this is the case I would not recommend the pulley change.
So is it worth fitting the pulley?
I am in two minds about it. This is more of a nice to have, or if you are on a mission to squeeze every little bit of power out of the car. This is not one of those mods that you would feel the power change driving the car. You may think you can feel a change but it is so small you will not really notice it. What you gain is not really worth the price you pay. I am not saying don’t buy the pulley I am just saying don’t expect a huge difference.
