Why take that airplane into the air and fight with a dead motor when you still have about 8000' of runway to burn. It will take you more than 30 seconds to reach the end at 114kts or so, so slowing you have plenty of time.
OK...going to show my stupidity here, fortunately it will come as a surprise to no one.

I always thought V1 was the speed at which you were committed to flying if an engine failed, due to the inability to stop on the remaining runway if you aborted at that speed or higher. If that is indeed the case, how would Pat's comment above work? If you have an airplane that can take off within 3,500 feet, on an 11,000 foot runway - how would you calculate V1? You obviously have much more runway than is needed, and if V1 is calculated based upon the stopping distance from a given speed, then V1 would be a very high number on this runway wouldn't it?
