* [[Truth in Television]]: Aircraft of all kinds (be they prop planes, helicopters or supersonic jets) do not always fly at their maximum speed. They have a 'cruise' speed at which they operate at optimum performance for distance, speed and fuel usage. The [http://en.[wikipedia.org/wiki/:UH-60_Black_Hawk60 Black Hawk#Specifications_Specifications .28UH-60L.29 |UH-60 "Black Hawk"]], for example, has a cruise speed of 150 knots (173 mph, 278 km/h) and a "maximum" speed of 159 kn (183 mph, 295 km/h). Some aircraft also have a "never exceed" speed, beyond which flight <s>can</s> '''will''' become dangerous. Jet engines are also rarely operated at maximum power, because it will reduce their lifespan considerably (and use disproportionally more fuel).
** The most notorious example is the Mig-25. It is "redlined" at Mach 2.8, though it can fly at Mach 3, but one aircraft that was tracked doing so ended up destroying its engines during the flight.
** Make that ALL aircraft. The Vne generally has less to do with the integrity of the motive power and everything to do with the fact that the airframe itself will start to come apart if the aircraft flies too fast.
** This applies to the four-stroke/two-stroke engine as well. These engines are usually never run anywhere near maximum RPM, for the reason that going that fast will cause a lot of mechanical wear and heat on the engine. Many cars sold have the ECU effectively cap the RPM before the redline (the area in the tachometer that has a red stripe along it). Of course, if you really need that power, you can hack the ECU to not do this.
** Also, combat airplanes technically can turn much tighter than they usually are made to - more often than not it's the pilot who can't take the fact that all ''his'' power (i.e. blood) is being [http[wikipedia://en.wikipedia.org/wiki/G-LOC |forcibly re-routed to his feet or head]]. Modern flight suits help fighter pilots sustain greater amounts of G-forces than [[WW 2]] pilots, but they still have their never exceed limits... which they'll sometimes exceed anyway in life-or-death situations.
* Similar to the aircraft example above, most military vehicles have governers to limit the amount of power the engines are capable of achieving; and thus limiting the vehicle's top speed. When deployed to a combat zone, one of the first things the crews do is remove, disable, or bypass the power governers.
** American military vehicle and radio systems, generators and other non-man-portable electronics, also have special circuit breakers to protect them from power surges or over-power states. In combat there are switches or software modes that will keep it running no matter what. It's called "[[Big Red Button|Battle Short]]" or "[[Exactly What It Says On the Tin|Combat]]", basically a switch or software mode that allows the operator to bypass the circuit breaker in emergency situations.
* As seen in the film ''[[The Fast and The Furious]],'' [http[wikipedia://en.wikipedia.org/wiki/Nitrous |nitrous oxide]] injectors can briefly give an internal combustion engine a massive burst of power, although the effects in real life are less reality-blurring than in the movies. Nitrous oxide doesn't make a car go ''faster'', since it simply increases the combustion power of the engine, making the car ''accelerate'' faster, unless your vehicle's speed is not limited by engine revs, but by engine power. If your top gear can propel the car faster at max revs than the engine has power to beat air resistance, then adding the nitrous ''will'' increase the vehicle's maximum speed.
** Nitrous oxide ([[N 2 O]]) breaks in the cylinder into nitrogen and oxygen. It increases both the concentration of oxygen, making the engine running hotter, and concentration of inert, increasing the cylinder pressure. This will result in a sudden and dramatic increase of revolutions.
*** This device was known as Haha-Gerät (Ha!-Ha! Device) in the WWII Luftwaffe. It enabled the pilot to squeeze some 60% more revolutions off the engine momentarily - enabling a troubled pilot to escape the enemy. It also worked as a psychological weapon; the Haha-Gerät spat out an enormous tongue of flame off the exhaust, giving an impression of the plane igniting. Often that was enough to convince the enemy that the plane was a kill already and give up the pursuit.
** Another similar device was WEP (War Emergency Power) on American turbocharged radial engines. It employed water-methanol mixture inhection in the cylinder.
* Our existing particle accelerators weren't capable of getting colliding particles to produce the Higgs boson particle. So we built the Large Hadron Collider, a 17 mile long particle accelerator, to give us ''more power!''
** And if that doesn't work, [http://en.[wikipedia.org/wiki/Super_Large_Hadron_Collider:Super Large Hadron Collider|there are plans]] to add '''EVEN MORE POWER.''' ''And'' potential plans for [http://en.[wikipedia.org/wiki/Very_Large_Hadron_Collider:Very Large Hadron Collider|another one entirely]] if that fails yet.
* This is basically the whole idea behind overclocking computer components. Likewise, sometimes defective parts can be 'fixed' by adding more voltage to force enough power through the problem. In the latter case, this is mostly a short term solution as too much power will cause issues of its own and long term exposure to overvolting will reduce the life span of the device.
* At the [http://en.[wikipedia.org/wiki/Battle_off_Samar:Battle off Samar|Battle off Samar]] on October 25, 1944, the captain of the destroyer escort ''[http://en.[wikipedia:USS Samuel B.org/wiki/USS_Samuel_B._Roberts_ Roberts (DE-413) |USS Samuel B. Roberts]]'' ordered his chief engineer to lock down the safety valves on the ship's boilers and run the steam pressure at above the ship's rated maximum -- in effect, overclocking the ''Roberts''' entire engineering plant -- to increase speed. [[Crazy Enough to Work|It worked.]]
* The human body often works this way. Muscles not getting enough oxygen? Crank up the heartbeat and respiration! And if ''that's'' not enough, lactic acid fermentation will provide you with the ''more power'' you need!
** And if ''that's'' not enough? Well, only a third of your muscles normally operate at any one time. Throw them all into gear. (Note that doing this causes massive tissue damage, so the body will save it for live-or-die situations. But this is where stories of people lifting cars unaided come from.)
* Railguns and coilguns work this way. The higher the electric charge in the rails is, the faster the projectile travels. Since railguns rely on the kinetic energy of the projectile to do damage, more power directly equals more firepower. On the downside, the faster the projectile travels, the more friction it generates, causing the rails to heat up and warp.
* As mentioned in a couple of previous examples, nuclear power plants (and to a lesser extent conventional ones) have variable power output and "100% power" generally refers to the maximum output within acceptable parameters. So it's possible, but very dangerous, to operate above 100%.
** The WWER 440 reactors at the [[NP Ps]] [http://en.[wikipedia.org/wiki/Mochovce_Nuclear_Power_Plant:Mochovce Nuclear Power Plant|Mochovce]] and [http://en.[wikipedia.org/wiki/Dukovany_Nuclear_Power_Station:Dukovany Nuclear Power Station|Dukovany]] are (safely) running at higher power than originally designed for. However, this required modification of several components.
* In closely matched street races, try turning off the A/C.
* The American "Big Three" car companies tend to take this approach to designing cars, often focusing on ramping up size and engine power and flaunting their '''''MORE POWER!!''''' in commercials. Like Tim Taylor's attempts, this blew up in their faces when the price of gas shot up, tanking demand for their powerful gas-guzzlers.

** Also played straight by the Bugatti Veyron Supersport. When the base model Bugatti Veyron's top speed record was beaten by the SSC Ultimate Aero, Volkswagen resorted to this trope to reclaim the speed record with the Supersport - [[Up to Eleven|they added around 300HP to the already powerful engine (which was already rated at over 900HP!)]].
** Ingeniously averted by many European and Japanese carmakers, who can somehow squeeze out performance from their cars without resorting to more power. An example is the 2007 Nissan GT-R, which despite being heavier and having less power, can keep up with the 2009 Chevy Corvette C6 ZR-1 on the Nürburgring Nordeschleife as shown [http://www.youtube.com/watch?v=e1h7S2Pa3Ho here]. And even with a bit more power, the upcoming [http://www.youtube.com/watch?v=CGQn6FF1VQQ 2012 Nissan GT-R] is still less powerful and heavier than the Corvette ZR-1, but already demonstrated potential superior performance in early tests.
* [http://en.[wikipedia.org/wiki/:SSME#Thrust_specificationsThrust specifications|Space Shuttle main engine: Thrust specifications]] at The Other Wiki says, "Current launches use 104.5%, with 106 or 109% available for abort contingencies." It's a convention, as they go on to explain, but sounds nice.
** Similarly, jet engines can sustain short bursts over their maximum rated thrust to take off or abort a landing.
* The ''[http[wikipedia://en.wikipedia.org/wiki/Z_machineZ machine|Z-]][http://www.sandia.gov/news-center/news-releases/2006/images/z-machine.jpg Machine]'', a device with a peak power output of 290 terawatts, over 10 times the combined power flowing through all of the world's electrical grid for a few tens of nanoseconds, generating a plasma implosion, an extremely powerful X-ray blast and lightning storm, and partially destroying itself. Originally built as a nuclear bomb simulator with an output of 50 tW, it's now being used as an extreme physics experiment and fusion power testbed, with plans to upgrade it to output 1 petawatt - 1000 tW. It's working principle, the Z-pinch, essentially involves gathering as much energy as you can and releasing it one extremely powerful shot through a couple of poor thin wires, causing said wires to explode into a plasma and then causing the plasma to then crush itself under its own magnetic field. This process, apart from generating huge amounts of X-rays creating, can generate stupendous temperatures, many times hotter than the center of the Sun. It is one of the ways of achieving inertial confinement fusion reactions - the other two ways involve having hundreds of giant laser beams simultaneously converge on a tiny ball of hydrogen as in the 500 tW [http[wikipedia://en.wikipedia.org/wiki/National_Ignition_FacilityNational Ignition Facility|National Ignition Facility]] or have a runaway fission chain reaction - a nuclear bomb - implode on a hydrogen target - creating a thermonuclear bomb.
* Laser pickups in CD players usually go bad either due to increasing opacity of the lens, or reduced power output of the diode. In theses cases, a very Tim Taylor fix of upping the calibration trimmer (increasing the laser's power) is employed.
* Similar to the ''Samuel B. Robberts'' example above, we has a civillian example of Tim Tayloring for an emergancy: The [http://en.[wikipedia.org/wiki/Rms_carpathia:Rms carpathia|RMS Carpathia]] had a registered top speed of only 14 knots (16 mph). When he got the ''Titanic's'' distress signal, what does Captain Rostron do? Cut off the heat to the A/C and hot water taps and redirect it all to the engines for ''MORE POWER!'' Doing so scored the 500+ foot long liner a speedy (for her) 17.5 knots (20.1 mph). ARR ARR ARR!
