I think there is supposed to be a difference between those two yes. Eric explained it somewhere on the forum, but I didn't find it. The numbers for the engine alone is only when the engine is running on idle, and so will always be far better than when in a car where you both have weight and aerodynamics to add to the mix. How large that difference should be however, I do not know.
As I couldn't find the ealier post to verify, my comment should so far be counted as guesswork.
