The main reason you get off the ground so quick at SNA is because there are noise restrictions. Correct me if I'm wrong, but every time I have flown out of there it feels and sounds like a full power take off and then when you get to between 500-1000 feet you get a very noticeable power reduction so that the aircraft is quiet when flying over Orange County, specifically Newport Beach. I'm sure the short runway has something to do with it, but we are usually off the ground in about 3000 feet which is only halfway down the runway.
