Using the start/finish straight, Yamamoto's top speed was 168 mph early on, then fell to 164 around lap 7 (probably due to a lack of slipstream). I've jumped ahead to lap 44, where his top speed is still 163 or 164, depending on the lap. I noticed the speed boost happens at the end of lap 47, and sure enough,

The top speed is then consistently 177 or 178 mph.
That's about 14 mph or 22 km/h faster than before.
For reference, my own top speed fluctuated slightly around 170 mph on this straight. Mostly because I would always brake later than the AI, because turn 1 is just so fun if you wait until the last possible moment to brake.
I’ve checked my replay of the Fuji race and the fastest lap also has a sudden boost in speed. I’ll try to do next race with boost off and see how it goes.
