How do I find out the gear ratio of my car?

How do I find out the gear ratio of my car?

The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).

What is a good gear ratio?

In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.

What is a 40/1 gear ratio?

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 is the strongest VW transmission?

I am by no means an expert, but I have learned quite a bit about trannies since I got into VW’s, and I hope this info will be helpful to someone. Found in ’76-’79 Bus. They have a 4.56 R&P ratio, and are considered to be the strongest stock VW transmission.

How do I know if my VW has a DSG transmission?

To tell if your vehicle has DSG, there’s one very easy test – simply look at the top of your gearstick! If your vehicle has DSG, you’ll see these three initials embossed on the top of the stick (or sometimes on the body of the stick, facing the rear of the vehicle).

How do I find my axle ratio?

Method 1: Count the number of teeth on the ring gear and the pinion. Divide the number of the ring gear’s teeth by the number of the pinion’s teeth. This will give you the axle ratio.

What is a good gear ratio for a street car?

If we have a daily driver, 2.55 to 3.25 gear ratios typically work best, whereas a street/strip application we would usually use a 3.42 to a 3.90 gear ratio, and race applications most commonly use a 4.10 and above gear ratios.

What gear ratio is better for torque?

With a 4.30 ratio, it turns 4 1/3rd times for every revolution of the rear wheel. The numerically higher gear ratio (in this case, 4.30) increases wheel torque and improves acceleration from low speeds. But the engine does have to run faster to achieve a given speed.

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 a VW IRS transmission?

I.R.S. (Independent Rear Suspension) IRS transmissions use solid axle shafts to connect the wheels to the transmission via CV joints at either end of the axles. IRS axles easily can be identified by the 2 CV boots on opposite ends of the drive shafts.

What transmission does a VW Beetle have?

Acceleration and Power The Volkswagen Beetle 1.8T comes equipped with a turbocharged 1.8-liter four-cylinder engine, which produces 170 horsepower. A six-speed automatic transmission is standard. A manual transmission is no longer available.

Which VW models have DSG transmission problems?

RECALL: More than 16,000 VW Polo, Golf, Jetta and Passat cars have dual-clutch transmission issue. The Golf has been caught up in a new recall. Volkswagen Australia has recalled 16,098 Polo, Golf, Jetta and Passat cars, and Caddy vans, over a problem with their DSG dual-clutch automatic transmission.

Are 410 gears good for highway?

Installing 4.10 gears improves the car’s performance on the track but with negligible effects to the highway driving. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing.

Is 3.31 a good gear ratio?

Those ratios provide very good acceleration with gas V-8s and diesels. Trucks equipped with 8-, 9-, or 10-speed automatics may work well with 3.31 ratios as the new transmissions have lower 1st and 2nd gears than the old 4-, 5- and 6-speeds, helping offset the axle ratio acceleration deficit.

What is the best gear ratio for power?

1 to 1 or direct gear, is always the best gear for fuel mileage, quietness, cooler temperatures in the transmission, and more pulling power. However, to run in direct gear, the rear gears must be either 2.64, 2.47, 2.21 and I think there is even a higher gear than the 2.21. The average speed today is 70 miles per hour.

Is IRS axle better than swing?

For all forms of racing, IRS is superior. Swing axle isn’t “10 times better” and it isn’t stronger. The only advantage swing axle has in drag racing is that its cheaper to make strong enough to survive. An IRS can be made to survive by using 930 Turbo CV joints, type 2 output stubs, SAW axles.

What year VW Bug is the best?

If you are in the market for a classic Volkswagen Beetle then 1967 is a great year to look for. These had a lot of the original styling cues that were found when they were first released in the 1950s but had improvements and refinements to make them more reliable.

What is wrong with VW DSG gearbox?

As they are constructed in a similar way and of the same material as your standard manual transmission clutch, they also suffer from the same wear and tear issues and failures. DSG clutch wear in the 7 speed gearbox result in clutch judder when accelerating from standstill or when changing gears.

Which gearbox is best?

Difference Between Manual and Automatic Car and CVT Car:

Factors Manual Car CVT Car
Mileage Higher Slightly Lower
Maintenance Cost Moderate Marginally Higher
Acceleration Superior Performance Great in Stop and Go Traffic
Number of Gears Five to Six + 1 Reverse One (Multiple Gear Ratios)

How long do DSG gearboxes last?

If you’re after an automatic gearbox, don’t let relatively uncommon faults put you off – a DSG is usually one of the smoother and more efficient types of gearbox, and most survive for at least 100,000 miles if not more.
