im pretty sure its 3.3:1
take the spur divide it by the pinion and multiply by 3.3 and it should give you the same ratio that the chart says

Actually its 3.5. The standard gear diff has 28 teeth and the drive shaft pinion is 8 teeth. 28/8 = 3.5. Multiply the internal ration by (spur gear/pinion). However, make sure if your are using an after market ball diff that the gear is the standard 28 tooth, because 3racing ball diff come standard with the 27 tooth mounted. However, they give you the extra gears (26, and 28 tooth separate)

I dont know if this will help, I compiled a few gear ratio charts together, and made it my desktop... (2nd attached pic is full size version).

Philip is correct, that 3.5 is the ratio. You can see on the top right, you have the gear ratio without the internal gear ratio applied, then using the internal ratio of the diff spur that you use, you get the 3 different ratio sets; 26/27/28(std).
