Well, you'll want to go no larger than 106 or so, and 105 is the standard one I use...
So, a 105T spur and 36T pinion will give you 6.56:1, which is pretty close..

I want to have a final ration of 6.6:1.
Will a 88 tooth spur and 30 tooth pinion fit in a TA05.
Will a 132 tooth spur and 45 tooth pinion fit in a TA05.
