IV. How Much Horsepower Can You Gain with an ECU Tune? The amount of horsepower you can gain with an ECU tune varies widely depending on the factors listed above. In general, most cars will see a horsepower gain of 10-20% from an ECU tune. However, some cars may see a gain of up...
How Much Horsepower Do You Need? The amazing thing is that most of what we require a car to do uses only a small percentage of itshorsepower. When you are driving along the freeway at 60 mph (96.6 km/h), your car engine has to provide the power to do three things: Overcome the a...
Since the turbocharger is reusing hot exhaust to spin the turbine and compress the air, it increases the power from smaller engines. So a fuel-sipping four-cylinder can see horsepower that you might expect a six-cylinder engine to put out while getting 10 to 30 percent better fuel economy....
1895: Ogden Bolton of Ohio patents an electric bicycle with a front-wheel hub motor. 1900: Professor Ferdinand Porsche develops the Lohner Porsche, the world's first hybrid electric car, with a hub motor in each of the front wheels. Each motor produces 2kW of power (2.7 horsepower). Phot...
A turbojet is the simplest kind of jet engine based on a gas turbine: it's a basic "rocket" jet that moves a plane forward by firing a hot jet of exhaust backward. The exhaust leaving the engine is much faster than the cold air entering it—and that's how a turbojet makes its ...
An aftermarket fuel injection conversion kit can replace a carburetor with fuel injectors. How much does a fuel injection conversion system cost? While there are a few systems available for less than $1,000, most cost much more than that. Does fuel injection increase horsepower? Depending on ...
How much horsepower are we talking about here? You can calculate how many foot-pounds of horsepower this engine produces using a common equation: The engine that makes 300 pound-feet of torque at 4,000 RPM produces [(300 x 4,000) / 5,252] 228 horsepower at 4,000 RPM. But where does...
Cooling system leaks -- Boat engines are water cooled, pumping about 30 gallons of water through the system per minute for a 300 horsepower engine. If a hose bursts or isn't tight enough, this water can collect in the bilge and once again, you could find yourself sinking. Check for corr...
How much electrical energy is generated by 100 W light bulb turned on for five minutes? How many horsepower is a 250 W light bulb? How is electrical potential defined? How many clocks does the MSP430G2553 microcontroller have? Describe the motion of your hand as you ...
How much horsepower is developed by a rocket belt, and how much can it actually lift? You may be stunned by the answer. Find out on the next page, where we provide you with a few of the more interesting rocket belt technical details. Flying the Alps Yves Rossy acquired the nickname The...
