How much horsepower does a Hemi offer? That depends on which specific Hemi engine you choose. However, Hemi engines can offer anywhere from about 450 horsepower to more than 1,000 for the Chrysler 426 Hemi. How much horsepower does a 5.7 Hemi offer? A 5.7 Hemi V-8 engine offers 395 hor...
Gas turbines are much lighter than radial engines for the power they produce. One place where you can still see the influence of the radial engine concept is in the two-cylinder engine of a Harley Davidson motorcycle. The engine from a Harley can be thought of as two cylinders from a ...
Horsepower: A motorcycle’s horsepower (HP)is a measurement of its outputin terms of how much physical force it produces. (Horsepower is not the same thing as displacement, but the two are related.) Motorcycles with more horsepower will usually cost more. Newness: Like cars,motorcycles deprecia...
When the wheels power the car, the mechanical energy becomes kinetic energy: the energy that the car and its occupants have as they go along. The challenge of building a car engine is to get as much energy out of each drop of fuel as possible—to make the car go as far and as fast...
The engine is usually concealed in a cowling of some kind, making them quieter and less likely to get oil or grease on the rider’s clothes. Scooters generally have less horsepower than motorcycles. The overall effect is a more “civilized” vehicle meant for practical daily use. Today, a ...
The CEO tools around the New Jersey suburbs on weekends on a Harley-Davidson. Or, shotgun in hand, he stalks duck and pheasant in the Adirondacks with his friend Tim Collins. “He’s an incredible shot,” marvels Collins. “Maybe not the best I’ve ever seen, but the best for ...
The engine’s cubic inch displacement and RPM at peak horsepower are required to determine filter size. Knowing those figures, use this formula to determine the minimum effective filtering area an engine requires. A represents the effective filtering area, the usable portion of the filter: ...
Motorcycle engines can have between one and six cylinders. For years, the V-twin design was the engine of choice for motorcycle engineers in America, Europe and Japan. The V-twin gets its name from the fact that the two cylinders form a V shape, such as the classic Harley-Davidson V-tw...
Though no one knew it then, this year's substantial redesign would carry the make through 1948: 116-inch wheelbase, Knee-Action linewide, attractive new styling by Harley Earl's Art & Colour Section, and five extra horsepower achieved with higher compression (6.5:1); new pistons; and ...
In 1895, DeDion-Buton introduced an engine that would revolutionize the motorcycle industry by making mass production possible. The DeDion-Buton engine was a small, light, high-revving four-stroke engine that could generate half a horsepower. Although DeDion-Buton used the engine in its motortri...
