Torpey succeeds Nick Cox as academy boss, with the latter having been promoted after Nicky Butt's extended time in charge.
Having arrived from Brentford at the start of the season, Torpey told manutd.com of his hopes this week: "You don't join a club like Manchester United if you don't embrace pressure.
“You see the pressure as a privilege. The thing that stimulates me is wanting to be the best at something and doing things that have never been done before.
“I know this is Manchester United, we've done amazing things in youth, but I feel it's my duty now to continue that. You know, I've heard that my predecessor, Nick (Cox), talk about carrying on the baton, and I believe in that.
“I've been very fortunate to have the tours around Old Trafford and Littleton Road and The Cliff and realise the heritage, you know, and I got to thank (club historian) Jason Leach for taking me around and showing me the ropes on that.
“What it made me realise was this club's been built on innovation and a real belief in youth and a bravery to implement youth and look after the club really by utilising the youth that we had and that privilege that I feel I've got now.
“That pressure just comes with that sustainability of that and creating young players that are ready for the first team. You know, we don't want it to be a token gesture, that we have players in our first team because we want to keep a tradition going. We want to have players that are ready, that can make impact, that can make our first team better, and most importantly, our fans can be proud of.
“You know, I genuinely believe that. I've been very fortunate now to watch players I've worked with over the years go on and represent their country, represent the club, win the best trophies. And there's no greater feeling than one of your own stepping out.”
