You can even think in terms of a wing. If a plane stalls in 1g straight&level flight at 100 Kts, it can sustain 2g at 141 Kts. (twice the lift, in other words)
Exactly the same principle applies to a prop, where the airspeed of the prop airloil is proportional to rpm.
I once took off (intentionally) in high pitch, because the prop seals were leaking, and the plane was light, and I thought if I kept the oil control valve for the prop closed I could keep the windscreen cleaner. I had plenty of runway & no obstacles, which was good because performance was terrible, but the prop leaked anyway.
