You must end the race DURING the 100% fame bonus period to have that count. Of course you must hire the Agent. Things have most probably changed since last update. A week ago I did start a 10 lapper (with 50% fame daily bonus) before midnight and  finished it sometime after... Got no extra fame for it. I'm pretty sure you have to start AND finish the race the same day to get the bonus.

Knowing that...8x fame race is very unlikely.
