Torini Gearing for South Australia

Gear Chart 2.JPG

This is recommended starting gearing for Clubmaxx medium, or Supermaxx Heavy.
Lighter drivers may prefer to remove one tooth and heavier drivers may choose to add one tooth.
Gearing in 4ss can be a personal preference and is a balance between corner exit speed and straight line speed.
Compromising straight line speed by adding more teeth is often effective in this class for overall lap time.
For Mount Gambier, use Southern/Bolivar Gearing.

Looking after your Torini Engine

AIR FILTER
Always Oil your air filter using quality air filter oil such as Maxima Fab1 or Motul.
We recommend spraying the inner (main) and outer (foam) filters with oil. Be careful not to overoil as this can block airflow to the engine. When the filter needs cleaning you can wash out with degreaser and allow to dry thoughly before re-oiling.
Failure to oil your filter WILL shorten your engine life. 

OIL
Run Genuine Torini Racing Oil, To ensure the best life for your engine and warranty coverage we sell and recommend genuine Torini Racing oil. Change oil regularly, no more than every 5 hours for Clubmaxx.


TEMPERATURE
Keep Head temp to a maximum of 200 degrees, 
Whilst the engine will be fine for brief periods of hotter running, a 200 degree maximum will make the most of your engine life. If you do not have a head temperature gauge, running a 95 Jet will always be safe (with the 21' spec emulsion tube) we also recommend and use the 45 pilot jet in this configuration.

CHAIN
Make sure Chain is aligned carefully, and ideally with a laser system. If running DSK system, Us a T4RK alignment stick or align sprocket carrier without the guides fitted at first to ensure a perfect alignment. Chain tension should be free enough that the rear axle spins freely and there is no resistance from chain. This will be looser than on many 2 stroke karts.


GEARING
Gear the engine to hit the limiter at the end of the longest straight on the track for a brief time, Running the engine on the limiter for a prolonged time can lead to premature engine wear/ failure.

Tyre Pressure?
MAXXIS Super Sport - 12.5PSI Cold, (or between 10 and 15PSI)

I personally use 12.5 PSI cold almost every session!
Depending on track conditions, driver preference and chassis setup this tyre can be competitive from 10 PSI through to 15 PSI cold. Low pressures work the sidewall of the tyre more and provide more bite, while higher pressures heat the tread surface quicker and provide faster straight line speeds. What works for someone else may not work for you so test and find what does! 

 

I would suggest starting at 12.5PSI in a practice session, running the kart on track for 10 laps, then upon coming into the pits, immediately reduce the hot pressures to 15PSI all round. You can check later when the tyres are cold, what this translates to as cold starting pressures for each corner of the kart.

The Maxxis Tyre has a tendency to get overheated during a session and therefore depending ontrack surface and driving style, lower pressures may be required to keep lap time consistency over a race.

Fitting a Torini Engine

T4 Specialise in fitting 4 Stroke engines, but if you are giving it a go, you will need to know that the standard Torini engine plate does not provide enough offset for most karts on the market. Karting Australia have provided an approved method of drilling additional holes to make it work well. please see the following link

Alternatively T4 Can provide a Torini Apporoved, Kartech mount plate which makes fitting a breeze.
