Angel Eye? What is that? ‘Angel Eye’ is a cool headlight feature found on the new (2001+) BMW 5 Series. The projector headlamp unit on the BMW 5 series has a pair of circular-shape rings that when light up, they produce a pair of halos. BMW calls them ‘Angel Eyes’. They are also referred to as ‘Demon Eyes’. They look very nice on the BMW 5 Series. They don’t serve any purpose other than for the nice and aggressive look, and to distinguish the newer BMW 5 Series from other BMW models at night. Great design for an already-great looking car. Would definitely look awesome if BMW put them on the 3 Series.

My install is a little different from the BMW. Only three quarter of the rings are lit up, like a crescent moon. They are not exactly like the full circle of the BMW’s Angel Eyes. Only BMW deserves the full circle; my humble CRX is not worthy enough for the full circle, but it still looks great! continue reading…

The centrifugal type supercharger

In general terms, a supercharger, which is also commonly known as a blower, is nothing more than a large air pump that is driven by a belt that runs off the crankshaft of an engine. Superchargers have been used on car engines for more than a century already, with the German car manufacturer, Gottlieb Daimler, being credited as the first person to patent a supercharger system for an internal combustion engine. His design was based on the twin-rotor air pump designed by the Americans, Philander and Francis Roots in 1859 and patented in 1860. The first production vehicles to use superchargers were built by Mercedes and Bentley in the 1920’s. continue reading…

The four stroke engine.

Custom-car.us is all about engine tuning and car performance; so if you want to know about car tuning, how to increase engine power and how to modify your car, then you’ve come to the right place. However, before we can start talking about engine tuning and increasing engine power and torque, we first need to have a basic understanding of how an internal combustion engine produces power. Therefore, over the next few pages of this section, we’ll discuss the various basic concepts and principles of the internal combustion engines and the common terms used to discuss engine modifications, such as volumetric efficiency, engine displacement and air density as all of these influence engine power and performance. We also have a glossary of car modification terms that you can check for the meaning of some of the terms we use on this site. Once we have a clear understanding of how a four stroke engine produces power, we can move on and start make our P.L.A.N.s to increase engine performance. continue reading…
