Quite a lot, as I might say. Was there any challange in the race? Presently I've been doing A-SPEC challenge #3, at the Nurb GP, and cutting the last chicane in a Lambo Avenator. No challange, makes for an easy 1.2 mill.
It was difficult for me until I learned the track and how to drive the 2J on sport soft tires. I kept getting into the grass and spinning trying to take the big downhill right into the uphill right turn too fast. I usually win about 10 seconds ahead without driving aids.
You can turn on the SRF and really whip em' if it gets on your nerves.
