How much faster than light, was "maximum warp" in 2250s. Based on Data:

a planet "in the Beta Quadrant", is 51,450 light years away, which would take 150 years to reach at maximum warp."

Light needs 51,450 years to travel 51,450 l. y. so...

How much faster than light?

Bot was right it was warp 7 meaning 7^3 343c maximum warp in series discovery about 2250. Later in 2267 kirk flew faster than warp 7 when 7 meant more than 343 c! Maybe warp 6 was 512c? Hinted in an episode so warp 7 maybe 1000c and flew even faster than warp 7.
64 warp 3 better tec than 3^3
128 warp 4
256 warp 5
512 warp 6
1024 warp 7.
