Can you change your final drive ratio?

Can you change your final drive ratio?

Can you change your final drive ratio?

What you can do is swap the actual final drive ratio (the front/rear differential) to a taller gear (numerically lower). The upside to that is better gas mileage and a higher top speed if you're not electronically limited. Downside is it will hurt your acceleration in all gears.

Can axle ratio be changed?

You can change the axle ratio, and you can do it rather easily. Quite a few members here have gone from one ratio to the next. People with 3.

How do I make my gear ratio higher?

If you want to create a high gear ratio, nothing beats the worm gear. In a worm gear, a threaded shaft engages the teeth on a gear. Each time the shaft spins one revolution, the gear moves one tooth forward. If the gear has 40 teeth, you have a 40:1 gear ratio in a very small package.

What does changing your gear ratio do?

Modifying the axles' gear ratios changes the amount of revolutions of the driveshaft per each revolution of the wheel. Going to lower gears (ironically, a numerically bigger ratio) will increase the rpms of an engine (taking for granted the same diameter tire and going the same speed).

Is 3.42 or 3.73 better?

The 3.

Which gear ratio is faster?

A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential.

How do you choose a gear ratio?

The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.

Does gear ratio affect horsepower?

No. That is the prime reason that horsepower is used to compare engines. Torque is completely affected by gearing, so torque is hard to compare across vehicles.

Can a tuner change the gear ratio of a transmission?

Luckily, some tuners, such as Sharkwerks, can alter the transmission’s gear ratios to improve acceleration and shifting frequency. There’s also the axle ratio to consider. As with the transmission, changing the axle ratio changes vehicle performance.

How to calculate the gear ratio of a car?

That’s done by multiplying the ratio of the first gear set by the ratio of the second gear set So 3 / 1 times 4 / 1 results in a ratio of 12 / 1 this means that for every 12 revolutions of the input shaft the output shaft will complete one revolution. Or in other words, the motor shaft is turning 12 times faster than the pump shaft.

When do two gears mesh together what is the gear ratio?

When two or more gears mesh together the arrangement is called a gear set or a gear train. For example, pinion with 18 teeth is mounted on a motor shaft and is meshed with a larger gear that has 54 teeth. During operation, the pinion makes three complete revolutions for every single revolution of the larger gear.

What happens when you change the axle ratio in a car?

As with the transmission, changing the axle ratio changes vehicle performance. A higher ratio means better acceleration, but worse efficiency. And because the engine now revs higher in each gear, the top speed drops. In contrast, a lower final drive ratio raises efficiency and top speed at the cost of acceleration.
