Leicester Tigers prop Dan Cole says England's fine home form will give them a big advantage when they co-host the World Cup later this year.
Despite narrowly missing out on the Six Nations title, England have won their last five games at Twickenham, scoring 181 points and conceding 91.
"The way our fans got behind us, we're going to be some force to stop," Cole, 27, told BBC Radio Leicester.
"It could be the difference. It's like playing with an extra man."
Stuart Lancaster's side finished second in the Six Nations for the fourth consecutive year, coming up six points short of tournament winners Ireland.
But Cole, who earned his 50th international cap in Saturday's 55-35 win over France, believes that there are positives to take from England's recent performances.
"It was the loudest I've ever heard at the weekend," he said. "I thought the roof was going to come off at one point. I don't think many teams will enjoy coming to Twickenham.
"We're disappointed not to win the title but beating France by 20 points at home, scoring 55 against them, is no mean feat."
Cole and his club team-mates have since rejoined Leicester, who are pushing for the Premiership play-offs and host second-placed Exeter on Saturday.
"We've got momentum from the weekend, we're all match-fit and played at a high tempo," he added.
"It's all to play for in the play-off hunt. There are a lot of points to be taken off teams."
