Gear ratios
Can anyone help solve an argument please?
In a discussion with a guy at our club recently gear ratios came up not unsurprising I know but he maintained that with the different sizes of spur gear available its possible to get the same overall ratio using different pinion / spur combinations. No argument there simple math will tell you that however, he went on to say that when running a stock motor you will get better performance using the combination with the larger spur gear to achieve the same ratio! I maintain that it makes no difference if you are running 5.7:1 it doesn't matter how you get there the overall ration is the same.
Who is right????
