Quick Answer: What Gear Ratio Is Best For Speed?

What’s the difference between 3.73 and 4.10 gears?

Use this rule of thumb: The higher the gear ratio, the easier it is to get the vehicle moving and better accelerating, but lowers top speed.

Vice versa, if the gear ratio is lower it has worse acceleration but a higher top speed….WHICH GEAR RATIO IS FOR YOU?3.73 RATIO4.10 RATIOHigher top speedLower top speed3 more rows•May 12, 2020.

Is 3.42 or 3.73 better?

The 3.42 is fine for towing smaller boats, plus you will get better gas mileage for everyday driving. If I were towing frequently on hilly roads, I might would go for the 3.73 for better gas mileage while towing, but the 3.42 should be fine with a 205.

Is 3.55 or 3.73 gears better?

3.55 will give you a little better gas mileage on the highway and slightly more highway oriented performance. 3.73 may be better for towing, lower end power (off the line acceleration), and may result in worse gas mileage on the highway.

Is a 3.73 axle ratio good for towing?

A 3.73 ratio is suitable for regular light towing. If you plan on towing a fifth-wheel trailer or anything heavier than 5,000 pounds, you should consider a 4.1 axle ratio. A 4.1 ratio allows a towing vehicle to start moving without as much throttle.

What is a 5 to 1 gear ratio?

For example, if a motor drives a 12T gear to a driven 60T gear on an arm, the 12T driving gear has to rotate 5 times to rotate the 60T driven gear once. This is known as a 5:1 ratio. The torque output is 5 times as much, however, the speed output is only 1/5.

How does changing sprocket size affect speed?

Sprocket size and final drive Gearing up adds more speed and decreases the final drive ratio. You can gear down by using a larger rear sprocket or a smaller front sprocket. Gearing down reduces speed and increases the final drive ratio.

Are 4.10 gears good for highway?

Installing 4.10 gears improves the car’s performance on the track but with negligible effects to the highway driving. … Switching from a gear set of 3.55 or 3.73 to 4.10 gears will affect your gas mileage slightly as your engine will be turning more times to rotate the rear wheels once.

How fast can you go with 4.10 gears?

On the highway a 4.10 gear will only be about 200 rpms more at around 75 then a 3.73. And with the Automatic you will need all the help you can get. Top Speed of our GT’s should be between 145 and 155 depending on the tune of your chip if you have one.

Is 300 a lot of horsepower?

It wasn’t too long ago when 300 HP was actually a lot for a road car. But now, rental cars and entry-level sports cars have more. Still, anything in that neighborhood is more than enough for the road.

WHAT WILL 3.73 gears do?

So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21. But it will also use more fuel in all situations because the engine’s rpm will be higher. … Four-wheel-drive trucks will have a ratio in the front axle’s differential that closely matches that of the rear axle.

Is 3.23 a good gear ratio?

The engineers likely chose the numerically low gear ratio for fuel economy reasons. … A later swap to a four-speed and 3.23 rear gears woke up the performance of the car considerably. Yes, highway rpm increased as well, but I rationalized it by deciding that 3.23 gears provided a good balance of performance and economy.

What’s the best gear ratio for 35 inch tires?

Depending on the axle, the next lowest ratio from a 4.10:1 is most likely the 4.56:1, which should be selected for towing and performance. Because of the extra weight associated with off-road tires, we usually recommend going with a performance-minded gear ratio for any tire size above 35 inches.

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. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.

What is the cheapest way to increase horsepower?

5 Cheap Ways to Increase Horsepower (Under £400) Posted by Amsoil, 12th January 2018More horsepower! … Upgrade your car’s air intake. … Upgrade the car’s exhaust. … Engine tuning & performance chips. … Install a boost controller. … Upgrade to synthetic engine oil.

What makes a car accelerate faster?

Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make. A car with more hp than torque will always be quicker since this gives a car acceleration and speed. … The two will offer the same amount of speed, but the diesel will accelerate more quickly.

What gear ratio is best for drag racing?

A car at the drag strip with 4.11 gears and a 300 HP engine will launch harder and will be quicker than a car that has 500 HP and gears that are way too tall. 80% of the race is the first 80 feet! If you can’t launch and GET to your speed quickly, you won’t run a good elapse time.

Is 3.73 a good gear ratio?

FACT: A 3.73 axle ratio is ideal for towing heavy loads on flat terrain and will produce increased fuel economy during steady-state, long-distance highway driving.

Are 3.73 gears good for highway?

Well, if you plan on doing a lot of freeway driving, you don’t want to choose a gear that’s too low for your car because you’ll be going down the freeway at too high of an RPM. … Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc.

Does gear ratio affect horsepower?

Motor HP does not change when you change gear ratios. The only thing that changes is torque. A dynamometer measures torque and RPM, and from those two values calculates horsepower. When you change gear ratios both RPM and torque will change but horsepower will not.

Do 3.73 gears make a difference?

The 3.73’s don’t go quite that far — but they’re with 10% of that change. So it will be a VERY noticeable difference. Highway fuel mileage will take a bit of a hit; city mileage has the potential to improve with the 3.73’s. All this assumes your rear tire height stays the same.
