From the Novak website, the recommended FDR for 4wd with a 4.5 motor is 12. So start with a 17 pinion and go from there.

You are going to need a big track to utilize that much power. Have you replaced all the plastic drive train parts with metal, put in the slipper, and rebuilt the diffs? If you haven't taken these steps, I think you will be melting the plastic parts very quickly.

Not saying it won't work, just that some carefully thought out upgrades are needed to put that motor in a four wheel like this.

you will never be able to use that much power , you will be alot better off with a 6.5 or even a 7.5 i bet your lap times will be alot faster than using the 4.5!!

I am running a 17tooth pinion with a Novak 8.5 brushless motor in my Durga.
The difference in the pinion gear size is the top speed/punch and how hot the motor/esc get. If your esc goes into thermal shutdown then use a smaller pinion. The smaller pinion will give it less top end speed but more punch off the line. The opposite is true for a larger pinion.
