But that said, I would only go up/down 1 tooth at a time until you find the sweet spot for you use.The Traxxas Revo 3.3 has more than just an impressive list of features to offer. If its at all sluggish, then consider going with a smaller clutch bell.
If you can easily spin the tires out of the hole with the OS engine, then you may want to go with a slightly larger pinion. On the Traxxas OEM 3.3 engine, I would certainly drop a tooth for larger tires, as power output of the 3.3 is more far more limited then the OS engine is. If your OS is tuned and running correctly, you should be fine with stock gearing and slightly larger diameter tires. For larger diameter tires, dropping a single tooth on the pinion can help. I personally don't do speed runs so going for top end speed isn't needed. Go to large and you can bog the engine down and make clutch work really hard.Īnd it depends on whether you want to bash or do speed runs. Larger pinion bell gives you more top end speed, but takes a little longer to get there.

That OS engine is a really nice upgrade for the 3.3 BTW and will give you a little more flexibility on your gearing.to a point anyway.īasic rule of thumb is smaller pinion bell will help turn the larger tires better and give you faster acceleration, but you lose a bit of your top end speed.

How to get the correct gear choise depends on what you want to achieve in the end.
Gearing for tire size is a give/take affair.
