I’m personally a big fan of the E39 BMW M5 and its 4.9 liter naturally-aspirated V8. Now, most car enthusiasts are, as the E39 M5 is often considered to be the best M5 and one of the finest performance sedans of all time. However, my love for it goes a bit deeper because I feel that its engine is the best M5 engine ever, better even than the beloved S85 5.0 liter screaming V10 of the E60 M5. Personally, I just love the sound of the old-school V8 and its silky smooth delivery a bit better. But what happens when you put a supercharger on it?

Well, it makes it insane. The stock car makes 400 hp and 369 lb-ft of torque. So it’s not exactly lacking in power and, when mated to a six-speed manual gearbox, it helped get the E39 M5 to 60 mph in under five seconds. Meaning it’s more than fast enough in the real world. But when you add a massive blower to it, it becomes very, very angry.

In the description of this video, this E39 BMW M5 is said to have a supercharger kit from Kompressor Tuning, making 750 hp. That seems like a whole lot. We also don’t really know anything else about the car or its tune, so we don’t know what else has been done to it to make that power. We also don’t know what sort of exhaust it has. All we know is that supercharging an E39 M5 sort of seems like a great idea.

We all love normally-aspirated engines, free-breathing motors. They’re the best. However, adding a supercharger makes the E39 BMW M5 an absolute monster, tearing down the drag strip far quicker than a stock car and it sounds fantastic. With the hood popped, you can see the massive supercharger and hear it as well. It’s a fantastic mechanical noise that’s hard to beat.
