That's tough, because it all depends upon your tune, I'd say...
If it's ran really rich (break-in rich) 4-5 minutes
If it's ran rich (safe side, but not break-in rich) 5-7 minutes
If it's ran around perfect tune(race tune) 6-8 minutes
If it's ran very lean 8-10 minutes (if your engine lasts that long)
