This is where you can tell if the numbers someone is telling you are real or not. We wish, but the engine is only making 300 HP. If you burn 24 gallons of fuel per hour to make 300 HP, 142lbs/1 hour, you release 2,699,520 BTU’s of energy, (19,000x 142). So 24 gallons x 5.92 lbs = 142 pounds per hour to make 300 HP. 1 Gallon of fuel weighs approx 5.92 lbs and for every 1 lb of fuel burned approx 19,000 BTU’s of energy is released. It may use approx 24 gallon per hour to make 300 HP. For reasons of simplicity let’s take an engine that makes 300 HP. 1 BTU is heat energy required to raise the temperature of 1 pound of water 1° F which is equal to 778 Foot – pounds of energy.ġ Horse power (33,000 Ft-lbs per minute) is the same as 42.4 BTU’s per minute or 2545 BTU’s per hour (33,000 /778 = 42.4165 x 60=2544.98).įor any engine you can calculate the amount of fuel used, its thermal efficiency and its horsepower potential. So, here are a few things to consider when hearing about all of these high powered internet engines.Įngines turns chemical energy (fuel) into heat energy (combustion) and some of that heat energy is turned into mechanical energy or work (torque). I thought if I put some basic proven and accepted calculations in a paper they can be used to obtain and understand what is real and what is not. The internet has created bragging rights for engines with huge horsepower figures, which never live up to the stated performance and seem to defy the laws of physics. Same can be said about cars that have real engines with real horsepower. There is a saying that money talks and BS walks.
