|  Final Gear Ratio
Can someone tell me what the final gear ratio is for a stock transmission with a 96t spur, 15t pinion and a 55t motor? How many turns of the motor equal one turn of the wheel is what I am interested in - can this be easily calculated? Sorry, I am not mathematically inclined, Sean |

Your ginal drive would be 34.9. Meaning to turn the wheel one time the motor must turn 34.9 times. To find your final drive ration you take your spur divided by pinion. (6.40 like pete said) and multiply by the gear ratio for the rest of the drivetrain, in this case that number is 5.4576. (96/15) X 5.4576=34.92864  |
