The Reds dominated at Loftus Road, impressing from start to finish as they romped to a 3-0 victory despite manager Brendan Rodgers' enforced absence.
"That is what we're aiming to do in every game," Allen told Press Association Sport.
"If we can get that level of performance as consistently as possible then we have some exciting times ahead.
"I am extremely pleased. We had a disappointing result, as everyone knows, away to Stoke so it is always important to bounce back first and foremost with a good performance.
"To score three goals and keep a clean sheet is a massive bonus.
"It was a good team performance but when you've got a player like Luis Suarez that can create and score goals out of nothing, it is a pretty big help."
