Almost every car manufactured nowadays has a car air conditioning system. Their function is to give comfort to the driver and passengers of the vehicle, especially on hot weather conditions. Air conditioners use significant power, and the drag of the car is affected whenever the air conditioner is activated. Besides the drag, effects on fuel efficiency is also being debated as well as other factors that make the difference between driving with and without air conditioners turned on.

 Fuel injection in cars started in 1955 when Bosch developed the fuel injection system in Germany. It was not a reliable system in the beginning. It only suited around thirty cars. However, since the fuel injection in cars
has been continuously developed and improved through the years, it is now acknowledged by a lot of people to be the better system than carburetor. Although there are still some ongoing debates about such matter, many have already subscribed to the belief that it stands on a higher footing than that of a carburetor since fuel injection system has lower emissions and better efficacy.

Gas mileage is defined as the number of miles a vehicle travelled in relation to the number of gallons of gasoline it burned. In terms of the metric system, it is defined as the number of kilometres travelled versus the number of litres of gasoline burned. Gas mileage is determined by an interaction of many different factors, ranging from the vehicle user’s consistently chosen driving speed to the make of the car itself, to the performance of its specific parts. Because of all of these, the gas mileage can be greatly affected. The interaction of these factors are very significant in helping a driver select a brand new car, but all these factors must be checked even more when buying second-hand. Considering used car mileage and its overall performance when buying second-hand vehicles need not be complicated.

Car fanatics and other speed enthusiasts will always have something to tell about muscle cars. If asked for a comment, these fans would gladly share their opinions about this type of car. But, how do we exactly define a muscle car? How does it differ with the ones that we have today?

Muscle cars are those high performance automobiles with powerful engines originated in the US. A huge variety of these American-made cars are still available today mostly as collectors' items. Similar to other valued stuff of the past decades, these cars are now worth thousands of dollars as their current market values grow each year.

Amongst those classic muscle cars that are hot in value and are favorites of vintage collectors include the Boss 429 Mustang which was made available in the late 1960's to early 1970's, the 455-cubic inch V-8 engine Oldsmobile 442 W-30, the “fully capable” Pontiac Firebird Trans Am SD455, the performance player and top dog Buick GSX Stage 1, the 450-horsepower V-8 Chevrolet Chevelle SS 454 LS6, Pontiac's step up offer GTO Judge Ram Air IV, the attractive Ford Mustang GT500KR, the high-profile Ford Boss 429 Mustang, the “ultra-aerodynamic” Dodge Charger Daytona Hemi, the limited edition Plymouth Hemi Cuda, and the hand-assembled Chevrolet Camaro ZL1.

We love our cars. We drive them to work, we drive our cars to run errands, we drive our cars for fun and some time we drive our cars just to drive. We put gas in our cars, we change the oil, we replace worn breaks and we wash them when they are dirty. We do a lot with our cars so why not go a bit further and make our cars better. Take the initiative and upgrade the performance of your engine. It does not matter what make, model, used car or new car; with everything we do in our cars it would be much more fun to do them “faster”! Here are our suggestions to get more from your engine.

 Why are fuel pumps important?

The fuel pump is one of the most important components in an internal combustion engine. While there are some engine designs where the presence of this pump is not required (seen in engine designs where gravity is the main driving force in sending the fuel into the engine. The pump mainly functions by delivering fuel from the tank into either the carburetors or the fuel injection system. Their operation can be regulated by either mechanical (commonly seen in motors that use carburetors) or electrical (commonly seen in motors with fuel injection) means.
