hrmm I dont know.. I'm still trying to push the boundaries of how fast I can nydus in.. I have to check back my replay but.. maybe in 10min game time? I tried to go pool->Roaches->Lair->Nydus as fast as I can.. as time progress, opponent have more view of their main base and nydus are harder to pop without them knowing it..

Last nite I did finish a game in around 11min (gametime) after my nydus pop behind this Terran's base, mowed his small defending forces (siege tank out of position is easy to kill )and he quit when my Roaches got to his mineral patch.. he may have tried to tech, hence the small unit count..

my other attempt at doing this strategy against another zerg backfired.. because he went Muta and my Roach army got creamed.. althou after watching the replay, I might had a better chance if I just send my Roach over rather then trying to Nydus it in.. since Zerg cant really do a wall off anyway right

Another way that i've been thinking is.. using Muta tu give sight and hold the "beach head" as I would like to think it.. so maybe the Muta can defend the Nydus while its poping.. and my roaches will try to finish the base.. but.. that will need longer time to setup thou
