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).
How fast is a 1999 Honda Valkyrie?
at 5,000 rpm. It has a fuel capacity of 5.3 gallons and has a fuel mileage of 30 to 42 mpg, with an average range of 190 miles. The Honda Valkyrie accelerated at 200 yards, top-gear from 50 mph to a terminal speed of 74.2 mph, a quarter-mile acceleration of 12.93 seconds at 104 mph.
What is the best gear ratio for acceleration?
Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc. Always remember, for very “give” there is a “take”. If you take lower gears to accelerate quickly from 0-60, you will give top-end speed.
What is the best first gear ratio?
For most street performance applications, a 10:1 final First gear ratio is usually considered optimal. The disadvantage of operating a 4.10:1 axle ratio on the street with a 1:1 high gear is excessive freeway engine speed.
Does gear ratio affect horsepower?
A higher numeric axle ratio (4.11:1) keeps the engine running in the higher horsepower range, thus improving performance.
What gear ratio has more torque?
A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.
What is the difference between 3.73 and 4.10 gear ratio?
4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster.
What gear 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 higher gear ratio mean 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.
Is 3.25 a good gear ratio?
3.25s are a good all around gear.
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.
Can I run 35s with 3.73 gears?
Well-Known Member. You can do it but it’s definitely not ideal. The ratios with a 5.13 first on a 3.73 rear end and 35’s (your proposed setup) is very slightly taller than what a stock 6MT Tacoma is in first gear so it’s not like you’re going to be causing massive wear getting started.
Are 3.73 gears good for 33 tires?
With 3:73 gears and 33″ tires you are fine.
What gear ratio is best for 35 in 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.
Should I Regear with 35s?
No, you don’t need to re-gear with 35s. However, definitely plan on a re-gear in the future and fall in love with your Jeep all over again. She loses pep with bigger meats without the regear – especially with the heavier 35″ tires.
How much lift do you need for 35 inch tires?
To install 35-inch tires you require at least a 6-inch lift, though that depends on the car’s backspacing, offset of its wheels and how wide your tires are. In some cases, fender trimming may be necessary before you install these tires.
