Default Gearing and tires
I currently have a moser 9 3.89 gears and run a 28” tire, if I go down to a 26” tire what can I expect to pick up at the 8th mile. Now I trap 93mph and 7.5x-7.7x depending on weather

What's the rest of the combo look like? If you are going to stay NA then it would be worthwhile to swap to a 26 or change your gears. If you will spray in the future, then stay with your current set up

So you probably peak around 6200-6300 or so then? If so, it sounds like you'd benefit a bit from a 26" tire

Expect a lower mph with the 26" tires though.
