The original Volkswagen Beetle, although it came fourth in the 1999 Car of the Century competition, is considered one of the most influential cars in history. With over 21 million units produced between 1938 and 2003, it was incredibly popular. It’s no surprise that Beetle enthusiasts still exist today and find different ways to customize their cars.

In the United Kingdom, there’s a group of people who enjoy installing superchargers on the Beetle’s air-cooled engines. They have a dedicated YouTube channel called “Kompressor Haus / VW Aircooled Superchargers,” which explores the technical aspects of fitting a Beetle engine with a supercharger. Their latest video features a supercharged Beetle going on a dyno run to demonstrate its significant power gains.

Before we dive into the dyno test, let’s talk about the modifications made to this Beetle. The engine has been upgraded from the original 1,600cc to 1,641cc, a common modification among Beetle enthusiasts. The car also has an upgraded carburetor setup and other minor tweaks that result in an additional 50 horsepower.

Now, let’s discuss the supercharger kit used in this Beetle. The kit is called the “Kompressor Haus Ultimate kit” and includes an AMR500 supercharger connected to a genuine Weber DCOE 40 carburetor with an MST serpentine pulley system. To support this kit, the car is equipped with an electric fuel pump and a crankcase oil breather. The kit costs $2,250 (1,750 British pounds) and promises to almost double the factory power of the Beetle.

But does it really deliver on its promise? The video takes us to the dynamometer where the supercharged Beetle undergoes a test to measure its engine power. The final numbers are impressive – 100.1 horsepower and 126.9 pound-feet of torque at the crank.
