Forced induction is the most popular way Mustang owners pump up their Modular engines, and this is Vortech's HO kit for the 3V Mustangs. Rob installed it six months after buying the car. The V-2 compressor supplies a maximum of 10.5 psi of boost, pumping the power numbers up to 482 hp and 410 lb-ft at the wheels. The supercharger is so quiet, you can barely hear it over the sound of the engine, and that contributes to this car's stealth factor. This kit costs a little more than $5,000, and Ron feels it's worth every penny.
