I know all the engineers out there can answer this in their heads, this one is for the younger set:

This super dragster does the quarter mile in 2.87228 seconds.

Assuming constant acceleration, how many g's is that, and assuming 100% efficiency in getting the power of the engine to the road, how many horsepower did it take to make that run? Perfect tires, no slipping, etc.

The sling weighs in at 1665 pounds or 756.18 Kg.
