Most modifications can offer modest horsepower gains. While 10 horsepower here and 40 horsepower there can add up quickly, you don't have to do much math to see the advantage of a supercharger. With just one modification you can nearly double your horsepower. That's a huge speed increase. Not only that, but superchargers offer other advantages. With a better throttle response, improved cooling, and high-quality calibrations, you'll be able to use all of that power without worrying about damaging your engine.

Many high-quality superchargers even offer a warranty because they are completely confident that their supercharger won't in any way reduce your engine's life or cause other powertrain issues.

Superchargers represent a huge investment. Not just in terms of cost, but also installation time. Installing a supercharger, correctly, is a serious undertaking. When you're finished, your engine will be fundamentally changed. Even your oil recommendations will change. But it'll also be clear when you're driving that you're not operating the same Mustang engine as before. With noticeable, observable results, superchargers remain one of the best modifications you can make for long-lasting performance.
