We have discovered that good cold, dense air increased the volumetric efficiency of the combustion chamber in an engine. Turbo kits, air intakes, superchargers, bigger injectors, and nitrous oxide are all ways of sweetening the air fuel mixture in the combustion chambers, but there is another form of boost that is often overlooked.
Ram Air Kits can get you cooler, high velocity air into the intake increasing horsepower. These kits usually use a hood scoop to channel air into an air "funnel" that tunnels the air into a 2-3 inch pipe connected to the intake. These ram air kits essentially give you increasing amounts of "boost" as the vehicle speed increases. They do not give any additional boost at idle, because ram air kits use the force of the outside air to push air into the intake, but at highway speeds, they can perform very well with 70mph of wind velocity reaching the intake!
These ram air kits are fairly easy to install, and for the money can be a good upgrade. There are some ram air kits available that can attach to a cold air intake, giving you the added gains of the cold air intake coupled with the gains of the added boost at higher speeds. To install one of these, you would need to install an aftermarket hood with a scoop already in place. These are sometimes called induction style hoods, and are available in fiberglass and carbon fiber. Or you can fabricate your own by purchasing a hood scoop and cutting the hole in your existing hood, but I would reccomend an induction hood designed for this type of application.
Keep the pedal to the floor, and as always, stay TUNED!
