DIY: Fresh Air Ducting for Stillen G3 Users

cotizi

Think of it this way. The power plant (engine) system can basically be modeled as whatever goes in must come out. (Mass isn't destroyed, its properties are just rearranged during combustion). So if you take that approach, the exhaust can only eject so much gas at a certain pressure. The stock exhaust is limited by physical parts dimensions and flow characteristics, not by the power production of the motor. If you agree with this, then its fair to say the intake system will only suck in as much air as it needs to satisfy its combustion requirements. It cant suck in all this "extra" cold air if there's no where it can go. The best that could happen is to decrease the temperature of air that actually IS going into the motor to be as close to ambient temperatures as possible.

If the whole point of modding is the get colder/denser air into the engine so that more fuel can be injected to create more power, it makes sense that to FULLY utilize the gains of air ducting, it helps to have more mods. With full exhaust mods, not only is colder air going into the motor (because of ducting and G3 intakes) but MORE of it is.



Technical reasoning aside, ducting isn't exactly a huge HP adder, I got bored and decided it would be fun to do. This weekend I'm gonna paint it all black! yay.
