Yeah, sort of.
It's the BTUs contained in a cylinder's worth of air at stoichiometric conditions (all of the oxygen in the air, and all of the fuel will be consumed, leaving no oxygen or fuelk left) that determines how much energy will be released by that cylinder.
Do more of them (more cylinders, or more times per minute), and power goes up. Put more mixture in (more size, or forced it in under pressure), and pwoer goes up.

The BTU is a unit of energy (along with the calorie and the joule). Power is energy divided by time.
So then, is a watt a unit of energy or of power?
How about a watt-hour?

Okay, here it goes
BTU (British Thermal Unit) - The amount of energy require to raise one pound of water 1 degree F.
Calorie: The amount of energy required to raise 1 gram of water 1 degree C.
Joule: The energy required to exert a force of one newton for the distance of one meter.
I can't remember what a newton is.

Joule: The energy required to exert a force of one newton for the distance of one meter.
I can't remember what a newton is.
newton = force required to accelerate a mass of 1 kg at 1 m/s^2. A mass of 1 kg will have a weight of about 9.8 N, because that's roughly how strong the Earth's gravity is.
Watt is power (1W = 1 Joule/Second)
Watt-hour is energy (because you are adding up the power over time)
Sometimes it is common to say BTU, when "BTU/hour" is really technically correct. Such as the capacity (power) of air conditioners.

alcohol and methanol have less btu per volume compared to gasoline.
yet a gas engine thats properly jetted to run on meth puts out way more power, and consumes alot more meth than gas.

To relate to horsepower:
1 hp = 2547 BTU/hour
When comparing fuels, higher BTU content just means more energy content. An engine running on premium fuel (that's tuned to run on it) can make more horsepower than on regular because it has a higher energy content. This is also one of the reasons that diesel engines get better mileage.
So yes; all other things being equal, higher BTU content fuels will produce more horsepower.

actually, premium typically has less btu per volume than regular. its premiums greater ability to resist detonation that allows it to give more power to an engine that is properly tuned with higher comparesion comnpared to regular.
I guess Cota & Cota must have some typos on that chart then.
>Calorie: The amount of energy required to raise 1 gram of water 1 degree C.
Clarification:
Calorie (capital C): 1kg of water, 1 degree C (This is the calorie that the energy in food is measured.)
not to be confused with calorie (small c): 1g of water, 1 degree C
