    Fact or Fiction ???

    You have a stock car with a given air intake velocity and given exhaust backpressure.

    *If you increase the intake velocity over stock and leave the exhaust the same(stock), you will create more back pressure, hence a drop in hp and torque.

    *If you have stock air intake and new exhaust with less backpressure, you may lose some low end torque but gain some high end hp.

    *NOW, if you increase air flow AND reduce backpressure by use of non stock intake box/filter and free-flow exhaust, would'nt it follow that you would have more hp and torque over the same rpm range as the original intake/exhaust setup???

    Zat iz ze Qwezchun???

    Looking for techinically astute replies based on experience and not old myth's. Thanks...

    Bottom line, I am interested in BOTH reducing backpressure and increasing intake air flow with the objective of gaining more hp and torque over the same rpm range I have with the stock setup....

    Have you tried your question at www.physics.com

    Interesting question though

    Re: Fact or Fiction ???

    I've been watching this site for months now. You guys make me laugh.

    Seems to me that more air flow + more fuel = more hp

    No Pcars yet, but soon.

    Fuel and rpm need to enter the equation

    if you add more air but not more fuel, then the stoichiametric ratio would be affected and you're right, you'd lose power. If the engine computer compensates with more fuel to maintain that ratio with increased air, then you'd have more horsepower.
