IRBR blow their starter hole. It is lotus that blows the diffuser through a hole below the starter hole.
Williams has done no modification to its starter hole, as such, I do not believe they are blowing it from the tunnel.
Again, not directly. Early RB tunnel had a duct that fed directly to the starter motor hole. Now they just exit the tunnel air around the gearbox and leave the starter hole open to all air that may be around there.
I'm not sure what hole below the starter motor hole you are referring to.
