How do you read gearbox ratios?
The ratio is the number of teeth on the driven gear (ring) divided by the number of teeth on the drive gear (pinion). So, if the ring gear has 37 teeth and the pinion has 9 teeth, the ratio is 4.11:1. That also means that for every one turn of the ring gear, the pinion will turn 4.11 times.
What is the best gearbox ratio?
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.
What is Gearbox transmission ratio?
The gear ratio in a transmission is the ratio between the rotational speeds of two meshing gears. 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 the gear ratio for 3rd gear?
In 1st gear, the engine makes 2.97 revolutions for every revolution of the transmission’s output. In 4th gear, the gear ratio of 1:1 means that the engine and the transmission’s output are moving at the same speed….General description.
| Gear | Ratio |
|---|---|
| 3rd gear | 1.43:1 |
| 4th gear | 1.00:1 |
| 5th gear | 0.84:1 |
| 6th gear | 0.56:1 |

How fast is 7000 rpm in 5th gear in R33?
Get a speed cut n Nismo’s 320km speedo, to get figures for redline speed on 5th gear… That is if anyone is brave enough to try…. dangerous behaviour on public street. More sharing options… 7000 rpm in 5 th gear in an r33 is 270 kph.
