World Superbike

[email protected]
Almost 25 years ago, when World Superbike first started, the machinery was pretty much showroom-standard 750 cc four cylinders and 851 cc twins. When 500 cc Grand Prix bikes had 50% more power than a superbike, 120 bhp was very respectable from an exotic four-stroke 750 cc four-cylinder such as a Yamaha OW-01 or a Honda RC30. The latest World Superbikes are still based on production machinery, but are highly specialised, and much closer to Grand Prix machinery in terms of power and lap...

The main disadvantage of a turbocharged engine compared to a naturally aspirated one is poor transient throttle response, commonly referred to as 'turbo lag'. This effect is something that roadcar manufacturers continue to improve with all kinds of clever technology such as variable geometry turbochargers. Turbocharged engines have many advantages. They are compact and, as such, can produce high performance from a physically small and light package. They are typically slightly more...

Le Mans exhausts

The Le Mans 24 Hour race is a very stern test of man and machine. 24-hour racing is a team event possibly more than any other in motorsport, and requires more effort and more concentration over the course of a race than any other type of racing. In terms of mechanical stress and strain, the load cycles just keep coming. The mechanical aspect of motorsport is typically concerned with making the lightest piece of equipment suitable for performing its task and which won't break before the...
