About 7 or 8 minutes with an OS91SZ non-pumped motor at 1920 on the head in idle up.

At 1750 headspeed and mild 3D flying I've got 10 minutes, but there was very little fuel left, none in the main tank and only a small amount in the header tank.
I'm now set at 8 minutes and have a safe amount of fuel still left in the main tank.
Considering that I haven't fine tuned it yet either. 91 Cspec w/pump and CY Muscle pipe.
I need to change gearing before I have it the way I want it.

About 15 minutes when doodling about, and about 12 when thrashing. land with about half a header tank.
