      Daryl Patrishkoff of Shelby Township, Michigan, has a vision for the American automotive industry. He firmly believes that our fuel of choice should be Compressed Natural Gas (CNG), not gasoline.  Until the full CNG infrastructure is in place a Bi-Fuel vehicle, fueled by either CNG or gasoline upon the driver’s command, is the bridge vehicle that can lead this transition.
      Patrishkoff heads up a three-man technical team developing this technology.  The advantages include 40 percent savings in fuel costs at the pump, 25-30 percent reduction in harmful emissions, 100 percent U.S.-provided natural gas and meaningful employment for the U.S. economy.
      Patrishkoff and his team, known as Performance CNG, LLC (, have been demonstrating practical applications on multiple vehicles. On their current project, they have converted a 2003 Mustang Street Legal Muscle Car to a Bi-Fuel configuration. It has taken thousands of hours and a significant amount of money to get the Muscle Car developed to automotive engineering standards. It is now a legitimate road vehicle which puts out 470 HP at the rear wheels (over 500 HP at the crank) on either fuel using alcohol injection.
      This Bi-Fueled Mustang Muscle Car was unveiled last year at the Woodward Dream Cruise. Since then, it Mustang has traveled to universities, community colleges, high schools, industry seminars and alternative energy events to bring awareness to this technology and the value proposition of using CNG as a fuel for many types of vehicles.
      Having demonstrated that using CNG does not decrease HP from a gasoline baseline, the next step is to show it can increase HP. For that purpose, Patrishkoff is raising an additional $55,000 of funding. About $15,000 of this total is needed for high-performance CNG components and $10,000 is required for engine calibration refinements on the Dynamometer. The remaining $30,000 is slotted for EPA 75 testing (emissions, MPG and horsepower).
