Does anyone run with there front overgeared (front spinning faster than rear) and what track conditions and type (tight and twisty or open) would this suit. Thanks

if by that you mean changing the side pulley for one with 1 less tooth, its actually almost 1.1 drive front to rear,and would suit a small to medium track with low traction. you can use same diameter all round like this or maybe 1mm larger on the back . in low traction conditions it gives you better traction in rear when you gas it and tyre wear is much more even good luck and enjoy

technically it is call front overdrive.

front overdrive is good for low traction track.

the downside are rear tires wear faster and possibility of strained middle belt when front overdrive is too extreme.

racers usually use 2mm - 3mm split between front and rear tires ( smaller front dia. ).

I routinely run front overdrive. What it does is give more on power steering. It allows me to really accelerate through turns. It give more corner exit speed. Many cars as you accelerate out of a turn tend to push as weight transfers to the rear. With the front turning faster than the rears it tends to reduce rear squat as well as pull the car throught the turn.

is this with using a 24 tooth or 23 tooth gear for side belt

You can get front overdrive with any front pulley. On an MTX4 with a 24t front pulley you will start getting front overdrive when your split is between 2 - 2.5mm. (If my memory serves me right). I would never consider using a 23t pulley on the MTX4 unless you want a lot of front overdrive.

There is an overdrive chart on mugen japans website.

Click on english, then on the right side.... setting sheets. You will see all kinds of sheets including the overdrive chart.
