How much horsepower does a helicopter need to run?
This number obvisouly varies but 10 to 15 percent is a good starting point. If you have a 100 horsepower engine in your helicopter, expect only 85 to 90 horsepower to actually get to the main rotor. Additionally, you would need to reduce the power by an additional small percentage to account for frictional losses in the drive system.
How much thrust does a helicopter engine produce?

How much horsepower does a Subaru Impreza have?
Horsepower is relative. A basic, low entry car such as the Subaru Impreza has a rated 152 hp engine. It’s sporty, but by modern standards, it’s not a barn burner by any stretch. If your only experience with driving is this car, moving up to the Subaru WRX-STI with a rated 305 hp engine, the difference is going to be downright scary when you press the go switch. My DD has 330hp at the wheels and is crazy fun but can get you into trouble real quick if you’re not an experienced driver. I hit 60 in the low 4s range, so sure, 300 hp is quite a bit. But, I’m not unique on the roadway; there’s plenty of cars out there with considerably more power than my measly 330hp. :-)

What does "less lift" mean in helicopters?
Less lift overall means the helicopter cannot carry as much load at high speed as it can lift off the ground in hover. Then at speeds, some lift is transfered to thrust, again reducing max weight.
Is it normal to think about engines?
But as I said, it is normal for people to think about engines in those terms.
How much HP does a helicopter have?
If the helicopter is relatively small and the engine is designed for aviation such as being lightweight, reliable and safe then 700 HP engine is actually a fairly decent amount of power. As an example the Robinson R22 has 124 HP (pictured) and the larger R44 has 245 HP. If you move up to a turbine class helicopter you are looking at higher power ratings like the Bell-206 Jet Ranger which has 317 HP or the Bell-407 which is the first to exceed your stated power rating producing just over 800 HP so something in a similar class to the Bell-407 would be the likely application. In helicopters you a
How much is one horsepower?
One horsepower is equivalent to 746 watts which is equivalent to 746 Joules / s. It is also equivalent to 746 newton*meters / second. From this equivalent, I presume that the direction of motion is upward and is against the gravity of the Earth for work to be done. There is no work done by moving the load downward. There is also no work done against gravity by moving the load horizontally. The proper power formula is Power = Force in lifting a load * speed of lifting the load.
How to calculate horsepower to empty weight?
You could also calculate horsepower to empty weight. Divide the max horsepower by the empty weight. Obviously this is very crude and many other factors come in such as type of rotor system and mission requirements. Some rotor blade airfoils will require more power to generate the same amount of lift than others. The weight of rotor blades has gone down with improved material technology.
How much drag does a 2 ton aircraft need?
So now our 2 tonne aircraft needs 2000 x g Newtons of lift to keep it up and therefore there is 2000/12 x g Newtons of drag to push against to keep it going. (The drag is one twelfth of the total weight because the lift in cruise is equal to the weight.) Call the drag force D. That means we will always be putting in D x v Joules per second (watts) in the cruise.

In another example we had a partnership with Airbus helicopters to use their EC135s for an Ab Initio training program for the Army and Navy called HATS 9000. We don't have a product offering to fit that mission and our competitor in commercial airplanes who was a fantastic partner in this space did have an offering, so it was a great partnership.
