While it's true that a more powerful engine can be more efficient, what
determines the speed that your Dak is travelling is the rpm of the engine, not
the HP. For example, if your truck is going 70 mph, we'll assume that the
engine rpm's are 2000, and assume that the engine HP is 100. If the engine in
the truck makes 150 hp at 2000 rpm, you will still only be travelling at 70
mph at 2000 rpm, assuming no change in gears, etc. However, now you are
supplying gasoline and air to an engine which is making 150 HP instead of 100
HP. I think we can all agree that the 150 HP engine will use more gas.
The numbers above are completely fictitious, so please don't jump on me for
false numbers, but the concept is valid.
