Edgefly - I may have mislead you 07N is actually 2200 feet long so even if I can normally land and get off in the first 1300 feet of it, I still have a comfortable margin of safety before I run out of runway. This is different, at last psychologically, than haveing only 1150 feet between obstacals. I'm not an enginer so I would be reluctant to comment on the idea of adding enough horsepower/torque/etc to make it over 50 foot obstacles in X number of feet. Just a comment based on personal experience - adding horsepower also adds weight, so a major part of your added horsepower is going to be used up in compensating for the added weight, therefore, the required increase in horsepower is going to be considerable. We have been talking mostly theoretically here. Why don't you just take your airplane out to a longer grass strip, mark off the distance between your obstacles, and do a couple of takeoffs and landings. Do you feel comfortable that you would be able to do it safely when the real obstacles are there?
