I thought I remember the crew revolving around the sun at 7 point something to travel back in time. All I remember though is that the Bird of Prey barely handled it in Voyage Home. I don't remember how Enterprise held up to it in TOS.
Wasn't the scale redefined somewhere between TOS and TNG?
It was. I think there was an edict from Roddenberry that Warp 10 was the ultimate speed, maybe because TOS had episodes where the Enterprise was doing Warp 13 or such and he wanted to get away from people writing in higher and higher speeds.
So the creators made Warp 10 infinite speed, and made Warp 9 = 9^(10/3)c, and drew an asymptotic curve between them so speeds can be arbitrarily fast between in the Warp [9, 10) range. Warp 9.999 is much much faster than Warp 9.99, even though that seems like a little change. There's no formula for the speeds between Warp 9 and Warp 10, though; it's a hand-drawn curve.
Then they decided that Warp 10 turns you into a lizard. Not sure there's a formula for that one, either.
There were some iffy bits with the TNG scale. I think someone said in "The Naked Now" that instruments showed them passing Warp 10 (explainable as instrument error I suppose, though it's a weird speedometer that even has a spot for the needle that's past infinity), and in "All Good Things" I think the future Enterprise D traveled at Warp 13. Either Starfleet had redefined the scale again in the future time, or that third nacelle was hella impressive.
