FINAL DRIVE RATIO KART |
 |
Both in the shifter karts, and in those at
fixed ratio, the choice of the transmission ratio is very
important to explot at the best the performance of the engine in the
different tracks and conditions. |

The ratio must be identified in order to have the right balance between acceleration and speed.
In fact, a too short ratio will give advantages in terms of acceleration, but inevitably penalize the maximum speed doing get to limiting or at regimes where the engine does not make more.
The choice must then be made based on the characteristics of the track, in fact on tracks with short straights or where, however, you reach low speeds, it is useless to keep a long ratio because it would not be used, as opposed to the tracks with long straights will be important to give priority to the speed, and then stretch the ratios. Another aspect to consider is the grip of the track, in fact, in low grip conditions have too short reports can be penalized because you risk having a more frequent traction loss that determines wear and overheating of the tires.
Translating these guidelines in choosing the right final drive ratio is possible
only using professional software that using the acquired
data calculates with precision the optimal ratio, anyway
just to have ideas more clear on what happens changing
the ratio to have some numbers extra can be very helpful.

With this utility you can see in advance how your kart behaves in terms of speed and acceleration with the ratio that you have installed, and compare the results by testing an another ratio. If you know the power curves of your engine and you see on the track that you can not use all the engine speed, or instead you stray too far from its maximum power, you can play with the transmission ratio until you find one that gives you the same speed but at a higher engine speed, to the benefit of acceleration at low revs, either case stretch to have more speed and acceleration at higher revs. These are just some examples, but thanks to these calculations can analyze behavior throughout the engine operating range.
