gear ratio

ratio 16-32. Anyone know what that equals when converting? For example 9:1 etc.
I'm guessing 16 teeth small gear and 32 teeth big gear. I want to order some but my ratio choices are:
18-42
16-32
and 16-41
So my question is...what ratio would be close to 9:1?

I think I figured that one out. Anyone know how many teeth are on the small and large dio gears with 9:1 ratio?

im assuming its for a "S" af/16 motor
18-42 8.1
16-32 7.1
16-41 8.9

Thanks tru72. It's an 87 se50 if that's the af/16. Would af/16 be stamped on motor somewhere or on a tag?

There must be additional gear reduction somewhere else, as those tooth numbers are no where near those ratios.
18-42 = 2.33 : 1
16-32 = 2.00 : 1
16-41 = 2.5625 : 1

an elite rear end has 4 gears on 3 shafts.

the 9:1 gears for the dio are 16-42.

lol try 3.5 in your figuring
42 divided into 16 = 2.625
2625 x 3.5 = 9.1875

Like I said there had to be another set of gears to get thouse final ratios.

hey Bear45-70, anyway i can get you to cut down the size of your sig. ? its a cool picture but its big for a signature.
Maybe you could go with something like,

Dac, Done. I didn't know it was a problem, sorry.
