Max-Torque would like to provide a forum for racers to discuss their problems and the methods they use to solve these problems. We are going
to continually offer hints and suggestions for racing, kart maintenance, and safety. Please let us know if you have any questions, concerns, or solutions. We will do our best to answer your questions and will
publish your solutions on line.
HOW TO USE THE DOWNLOADABLE SPEEDCHART
To calculate the speed of
your kart is simple. There are four variables that
will determine the speed of the kart— engine rpm,
gear on the crankshaft of the engine (or clutch),
gear on the rear axle, and wheel size. Change any
one of these variables and it will affect the speed.
Getting these variables way out whack will
definitely affect the ability of the vehicle to get
moving. If the vehicle will not even move without
pushing the kart to get it rolling is an easy
indication that you better change something fast or
you will burn up the clutch real quick.
After you download the speed
chart, enter your own info into column “G”. All you
have to do is scroll over to those numbers and
replace them with your own. The calculations are
done instantly on the variable that you have just
replaced.
When it comes to racing
there is no replacement for the stop watch. The stop
watch will tell you how long it is taking you to get
around the track. You might think you are going
faster because you have increased the speed but how
long is taking you to get up to that speed? If there
are more turns then straight a ways, then you are
dreaming, that increasing the speed is going to make
you faster on the track. If increasing the speed
means you have to brake more and sooner because you
cannot drive into the turns carrying the speed you
are at then you have not accomplished anything by
increasing the speed. The stop watch is the final
determination if the changes have helped or hurt
you.
If you know the
circumference (distance around the wheel) all you do
is divide by 3.14 which will give you the diameter.
Example: wheel circumference is 34.25” divided by
3.14 = 10.90” diameter.
