switching from 48 to 32 pitch need help

[brushlessboy16]

i run 9/40 mod1 on my slash

[jayjay283]

I did that for my vxl rustler
31t 48p =17.46mm
20t 32p =17.46mm

76t 48p spur = 41.48
wanted a bit bigger spur (had the cogs)
So 54t 32p = 44.45

edit: thanks to Brians calc ! like I would've/could've done the math lol

couldnt i use a bore reducer?
im running brushless in it on mod1 but if i were to switch back to stock to run in the wet it would be nice not to have to change the spur and everything

Great i'm putting my order into tower today. With the S-600 motor I would assume it could be geared more like a titan than a normal 540 sized motor. Since i'm making the switch to 32 Pitch I might as well do it on all my traxxas stuff So I'll swap over my low buck basher pede as well. How would you gear a Pede with 5.5 tall Imex tires and a S-600 motor?

I'm thinking 56T spur with a 16T pinion. Can I go higher on the teeth on the pinion ?

Thanks Again guys.
