We recently installed a ProCharger P1SC on Kevin Smith’s 2020 Mustang GT350. The flat crank V8 pumped out 435 RWHP stock. After our usual flawless install and dynotuning we made 687 RWHP for a gain of 252 hp. Using a 20% correction factor indicates 859 hp at the crank. Attached is a video of a pass on our Dynojet chassis dyno.
Here’s the before and after supercharger installation and tuning. The horsepower curve is still rising when we shut down.
