Gear Ratio's - Need some Math Help
Ok, so I am trying to figure out my final gear ratio and all those other gear ratios, so I can input them into my data logger...
Here is what I have so far. Spur Gear - 44T Pinion Gear - 13T For a Primary Drive Ratio: 3.38 Front / Rear Diff Ratio: 4.30 Final Drive Ratio: 14.53 This is in a RC8e... Stock front/rear diff gears. Does this look right? |
Looks right to me

You need to get ahold of Tonys screws, he has a sweet gearing calculator that will do everything you need.

divide the big number by the little number.

Spur / pinion = primary drive ratio front/rear diffs - Big gear / Little gear = Diff Ratio You take the Primary Drive Ratio * Diff Ratio = Final Drive Ratio So in my case... 44/13 = 3.38 F/R ratio = 4.30 Final Drive Ratio - 3.38 * 4.30 = 14.53 |
