Supercharging is the easiest and most cost effective means of adding an average of 100 more horsepower and 70 ft/lbs of torque to your Nissan 350z or Infiniti G35. Actual numbers may vary for your application. There are many ways to increase performance. Add up the cost and time involved with all the external bolt-ons and you will find that you get about half the power of a Vortech supercharging system for around the same price. Add up the cost and time involved and extensive internal engine upgrades and you will find it will compromise driveability, emissions, and will not deliver the performance you expected for considerably more money than a Vortech supercharging system. Vortech supercharger systems are street legal, offer more horsepower per dollar and install in less time than performing internal engine modifications.
