No, actually if you the lengthen the handle you will decrease the amount of psi required to apply whatever torque the wrench is set at. )</font>
One way to do it if you're only doing it once in a while is to extend any wrench with a piece of pipe and then connect a pull type scale to the end of the pipe. Apply your force to the other end of the scale. For example if you are using a 5' pipe, to apply 450 ft lbs of torque you would need to apply 450/5 = 90 lbs of force on the scale. Just remember that the actual length of the pipe is determined from the center of the nut to the point where the scale exerts it's force. (and the scale pull needs to be perpendicular to the pipe) This method will provide a measurement of torque that is actually more accurate than most torque wrenches. Also make sure you lubricate the nut before you torque it or a major portion of what you are measuring will be friction, not the actual torque required to produce the required stretch in the bolt.
