Gearing questions

also, gear reduction is a co-conspirator with torque multiplication....
it takes torque to get a car moving...and the more torque to the rear tires, the harder and faster it will accelerate

SO...let's say your engine puts out 300 lb-ft to the driveshaft....

a gear reduction of, say 3:1 will put 900 lb-ft to the axles...4:1 would put 1200 to the axles

the numbers are random, just for illustration, but that's how it works
