I got this today doing the mixed drag late on a weeknight 12 am EST (only 4 drivers on average in the lobby). Used the stock Hoonicorn and turned all assists off and to manual clutch (I forgot and left it on manual for my first attempt but realized the Hoonicorn was beast). I basically held
and pushed
when I redlined at 9, it wanted to struggle and shifting was off since I wasn't using the clutch. I came in 3rd the first heat because I was used to regular manual but came in first the next two easily even with dirty shifting.
Hope that helps others who may not have had success on the track or trying a private lobby.
