to 'mo3000',
it sounds to me like you dont have a clue what you're doing advising people on how to get more power !
so you're saying the only way to get more air in is by bigger throttle body ? - what a load of **** !
i'm telling you right now that modifying an original air box will make more power and i have the dyno print-outs to prove it !
and what does this bulls**t statement mean - "standard air intake is the same size as the outlet to the engine"
you need to do some homework you silly little kid. ha ha
lee - this guy has no idea what he's talking about.
Sounds like concept is obviously proud of his skills with a hacksaw, but sadly has no concept of how an engine actually works.
Do you know what a thottle body does? Obviuosly not.
The throttle body controls the amount of air that enters the engine. So no matter how much air you can get into your precious filter box, it has to pass through the throttle body in order to enter the engine. if you take of the air inlet pipe just before the throttle body you will see that the total area of the two throotle butterflys is already smaller than that of the air inlet pipe, so in order to get more air past the throttle butterflys you can do one of two things.
1) pressure charge it, (turbo, Supercharger etc) therefore forcing the air through the buterflys. This is the pricinple (although it is obviously not as powerful as a turbo or supercharger!) behind mounting the air inlet pipe to the filter box as close to the front of the car as possible so that the 'Ram-air' affect of the car moving foward pushes the air into the engine.
or
2. Make the throttle body, (and the butterflys) bigger. This means there is less resistance to the air flow so you can get more air into the engine.
Oh and by the way.
You will find that i do know what i am talking about as i Have a degree in Engine Design and did one of my project on pressure charging, (getting air into engines..... 'Numb nut').
I hope this clears up any confusion over 18 year olds waving daddy's hacksaw around yelling ' I'm gonna stick some 12mm Ignition leads on it........ you know i might gain 500bhp!'
T**t.
I rest my case.
