||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
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 ratio not
always easy, for this to have some numbers that clarifies the
ideas can be very helpful.
Calculation Kart Optimal Ratio
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.
