To make racing more exciting.

They are designed to perform their best depending on what type of racing they do.

What about it? Model/type # as of 10-28-08: 124335-8104-01 Lists for a grand or so. Cool motor, but I am not bound by racing rules, and prefer to modify my own for a fraction of the cost. Makes little sense for run-around yard karts or what-not.

The 525 is faster for racing. but on flat ground the raptor would be faster.

They have lawn mover racing, moped ice racing (hilarious!), and use Briggs and staton engines in Jr dragster.Or are you asking about a certain type of racing and all the various machines that they use. Say jackstands, jacks, wrenches, pullleys, tire heaters,etc

Engine SizeThe Briggs & Stratton Raptor engine features a bore between 2.56125 and 2.5625 inches and a stroke of 2.438 inches. This corresponds to a total engine displacement of 12.48 cubic inches per engine cycle.More modern Briggs & Stratton 5 horsepower engines feature the same 12.48 cubic inches of engine displacement, but achieve that volume of displacement using a wider bore and a shorter stroke. The currently produced Animal, 206 and World Formula engines feature a bore between 2.6875 and 2.6885 inches and a stroke of 2.2 inches.Compression RatioThe original Raptor series of engines featured a compression ratio -- the ratio of the length of the stroke to the length of the combustion chamber -- of 6.5 to 1. Despite their shorter strokes, modern Briggs & Stratton engines also feature shorter combustion chambers and thus have higher compression ratios. The World Formula has a compression ratio of 9.5 to 1, the 206 has a compression ratio of 9 to 1, and the Animal has a compression ratio of 8.5 to 1.Ignition TimingThe factory-specified optimal ignition timing for the Raptor engine is 22 degrees before top of dead center (BTDC). The Animal, 206 and World Formula engines are factory-designed for an ignition timing of 29 degrees BTDC.Aftermarket ModificationsMany users modify their Briggs & Stratton racing engines to improve on, or the stretch the limits of, engine performance. If you purchase a used Briggs & Stratton motor, ask the seller about any modifications that have been performed and how they may affect engine performance.Read more: Briggs & Stratton 5 HP Engine Specs |

the same way that Nascar was invented...moonshiners made cars faster and faster then they started racing to see which one was faster..dirt racing has been around forever nascar evolved out of it but dirt track stayed the same. well it has grown in popularity over the past 30 years. has a search feature for authorized B&S Racing dealers nearest to you.

If the mass of the racing car is low, it is able to move faster; and if the racing car has wheels wide apart, the mass is spread on a large area and can travel faster and cover a bigger area at one time.

F1 is the fastest circuit racing in the world.

Increasing horsepower and improving aerodynamics.

it started in 1948 after moonshiners needed faster cars to outrun the cops and then they started racing their cars

That depends; faster than what? A werewolve can be faster than a few things, but not everything in the world. Yes it is quite faster than a racing car, idling in neutral that is.

They have more tuned and often bigger engines. -That's why they call it 'racing'That's why they are called "racing cars"

it's fun and also see who is faster

No, horses run way faster than rabbits
