How to get more torque?

[Parisienne305]

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.

Can i bring in too much air into the motor? (by doing what i just posted above)
Thanks

no
