My typhon 6s drag car build

[y noT]

I would like to get an array of pinions for drag purposes. What pinions would you all try out . I have a 46t spur in middle and way going to get . 20 21 22 23 and start there . Any suggestions. Also limited selection for 8mm mod 1 pinions??? Help please

I have the 46 spur with a 25 pinion (biggest pinion that will fit with the 46 spur) and about to drop a 38 spool in. And doing around 80ish. Wonder whe the spool will pull.
