    Thumbs up How to get more torque?

     



    What parts are responsible for producing torque?

    Should torque always be pretty close to the hp of the motor?

    What would bring the torque up a few notch on a 305? (I know, i know, should swap it for a 350, blah blah blah!. But i wont!)

    And how do we determine what kind of gears to put at the other end to make it more efficient (no loss of torque/hp)

    Thanks!

    "What parts are responsible for producing torque?"

    All of 'em.

    "Should torque always be pretty close to the hp of the motor?"

    Horsepower is a mathmatical function of torque. They are always equal at 5,252 rpm's.

    " What would bring the torque up a few notch on a 305?"

    Standard hot rod procedures. Getting more mixture through the motor.

    "And how do we determine what kind of gears to put at the other end to make it more efficient "

    You gear the car for what you want to do. Numerically low gears for good fuel mileage (for instance 2.50:1, 2.80:1, 3.00:1) or numerically higher gears for maximum performance (for instance 3.90:1, 4.10:1, 4.56:1).

    With gears, it's the number of power pulses per revolution of the tire. In a 4-stroke V8, there are 4 power pulses per revolution of the crank, so a 4.56 gear will apply 18.24 power pulses per each revolution of the tire, a 2.50 gear will apply 10 power pulses per each revolution of the tire.

    Thanks Tech!

    So if i plan on using my car on a daily basis, i should probably stick with gears around 3.something, right?

    Also, i read somewhere that the better air flow that gets in, the better results...

    If that is true, i was thinking of having two air intake underneath the bumper, bring them to a ''Y'' pipe and into the air filter ''cone'' (don't know the real name of that thing!); would that help?

    Thanks!

    The general rule of thumb with air temp is that each 10 degrees reduction in intake air temp results in a 1% increase in power due to the air being denser. So, yes, duct cold air to the motor.
