Last weekend I took the Hudson to race the Bonneville 100 Open Road race that starts just south of Wendover, NV on HWY 93A and goes 50 miles to the 93 junction and races back for a total of 100 miles. Everything started out great and at any given time there was a crowd around the truck checking it out. Friday was my Rookie Qualifying and practice and Saturday was the race.

Performance enthusiasts know that when it comes to engine air and fuel temperatures, colder is better.  With that in mind we first introduced the first CO2-based fuel and air cryogenic super coolers for drag racing applications in 2003.

The CryO2® system uses liquid carbon dioxide (CO2), stored at 80 degrees below zero (Fahrenheit), to super cool intake air, fuel, and even a vehicle’s turbo intercooler, resulting in more power and cooler engine combustion chamber temperatures.

The technology as well as the theory behind CryO2 have been around for decades.  Liquified carbon dioxide has been used in commercial cooling applications such as soda fountains and beer taps.  And both street and strip racers have long known that a cold, dense fuel/air mixture carries more oxygen and more fuel to the combustion chamber than a warm mixture.  Performance enthusiasts have seen this scientific fact put into practice for over 35 years in the form of ram air, cowl induction and cool air intake tubes.  A cooler air/fuel mixture also burns better, eliminating hot spots and pre-ignition problems that occur frequently in high-compression engines under load.
