How do I find out what gear ratio My Mustang has?

How do I find out what gear ratio My Mustang has?

Multiply the speed of the car by 336. For example, if the Mustang was driven at a speed of 50 miles per hour, the result would be 16,800. Divide the result found in Step 3 by the result found in Step 4 to determine the gear ratio. Here, 65,000 divided by 16,800 equals 3.869.

How do I know what rear axle gear ratio I have?

Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio.

Is 3.31 a good gear ratio?

BEST TOWING RATIO: In general, the best towing axle ratio for most of the post-2010 pickups is in 3.55 or 3.73. BEST MPG RATIO: If getting the best fuel economy is priority, then choose the lowest numerical number offered, such as 3.08, 3.23 or 3.31.

What rear axle ratio is best for fuel economy?

For instance, a 3:31 gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops. The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy.

Does gear ratio affect mpg?

Gear Ratio Effect The effect is generally minimal and will account for less than a single mile per gallon, and typically the gains are generally seen at highway speeds. The transmission gearing directly affects the fuel economy at a given speed. The engine’s rpm and fuel consumption are generally lower in higher gears.

What gear is best for fuel economy?

All cars are designed to start at the lowest gear, as that’s where you get the most power for acceleration, but driving at the highest gear will increase fuel economy. Fuel consumption will increase when you stay long at lower gears. Driving slow at the highest gear will also increase fuel consumption.

Does missing out gears save fuel?

Missing out some gears saves fuel by reducing the amount of time you spend. Missing out intermediate gears helps to reduce the amount of time you are accelerating. Because fuel consumption is at its highest when accelerating this can save fuel.
