Something else I also found out today at Sol2. After the first right hander, and the sweeping left along the open section, I used a turbo only to land on top of 3 other crafts battling it out on the approach to the sharp right turn.

From there I was seemingly hovering above these guys whilst travelling at the usual speed as if I were hovering above the track. However, I was able to do a barrel roll, but not have it execute till I found a gap to hover above the track again.. It looked funny till I found the footing and went straight into the wall with a surprise boost
