  1. How Long Do Tires Last?

    The average life of a tire is determined by the conditions a tire is exposed to throughout its life - not measured in calendar years. Temperature changes, sun exposure, storage conditions, usage, and maintenance schedules all contribute to the rate at which a tire ages. It is impossible to determine a tire’s exact life expectancy, because there is no way to account for the level of influence any one of these factors may have on a tire. However, you can defer to the vehicle and tire...
  2. Entertainment Systems- from AM Radio to Bluetooth

    Over the past 97 years, “entertainment systems” in cars have evolved from primitive 6-volt dry-cell AM radios to high-tech Bluetooth units. It is interesting to take a look back to see how technology has changed over the years. Here is a brief, illustrated chronology of these devices: 1922: First radio in a Car The first radio (“Marconiphone”) appeared in a Daimler car at the Olympia Motorshow in England. 1927: First Radio in Mass-Produced Car The “Transitone” radio appeared in a...
  3. Uses of WD-40

    WD-40 is truly a versatile product. It was created in 1953, by three technicians, at the San Diego Rocket Chemical Company who were searching for a rust preventative solvent and degreaser to protect missile parts. Its name comes from the project that was to find a “water displacement” compound. They were successful with the 40th formulation, thus Water Displacement #40, or WD-40 was born. Initially it was purchased, in bulk, by the Corvair Company to protect its Atlas missile parts....
  4. How Do Navigation Systems Work?

    Getting lost while driving, or stopping at a gas station to ask for directions, has become a thing of the past. With GPS in your car’s navigation system, in the portable navigation device on your dashboard, or in your smartphone, it is easy to pull up a map and see where you are, or get directions to where you are going. GPS makes you safer, routes you around traffic delays and helps you find nearby services. GPS (Global Positioning System), a technology we now take for granted, started...
  5. Spare Tires

    If your Challenger has a compact spare tire, it can be negatively impacted by lots of conditions, from heat, exposure to UV rays, and even time. It is recommended that you check your spare every time you have your tires rotated, approximately every 6,000-8,000 miles. When inspecting your spare, check for: proper air pressure signs of aging damage excessive wear Spare tires age like any other tire. Even if your spare tire never sees any use, it is still affected by the passage of time. As...
  6. It's Hemi Day!

    It’s 4/26/19- Hemi Day! Dodge has announced that the order books are now open for the “Hellephant”- Mopar’s supercharged 426 Hemi crate engine. Since the 2018 SEMA show, over 1,000 orders have been taken. The motor carries Part No. P5160194 with a price tag of $29,995. That translates to the low price of $29.99 per hp., a price that will be recognized as a relative bargain by anyone who has tried to achieve 1,000 horsepower on their own. Chrysler says its Hellephant engine installation...

  8. Dodge Unleashes a Stars & Stripes Challenger & Charger

    Dodge has unveiled its latest Murica upgrade- a cool Stars and Stripes Edition- for the Challenger and Charger at the New York Auto Show. The appearance package is designed to be a patriotic salute to our military men and women and will be available starting in May 2019 for the Scat Pack, R/T, and GT RWD models. Steve Beahm, FCA's head of passenger car brands in North America, summed it up as follows: "The Stars & Stripes Edition is an opportunity to deliver a custom look with unique...
  9. History and Applications of Carbon Fiber

    Carbon Fiber is a polymer and is sometimes known as graphite fiber. It is a very strong material that is also very lightweight. Although carbon fiber is five times stronger and twice as stiff as steel, it is lighter than steel; making it the ideal manufacturing material for many parts. These are just a few reasons why carbon fiber is favored by engineers and designers for manufacturing. Carbon fiber dates back to 1879, when Thomas Edison baked cotton threads or bamboo silvers at high...
  10. Limited Slip Differentials

    A limited-slip differential (LSD), or “anti-spin” differential is a type of differential that allows the rear wheels on a vehicle to turn at different speeds when executing a turn. They are widely used in high performance and four-wheel-drive vehicles because they provide superior traction abilities. Various types of differentials can be classified as "anti-spin." These include limited slip, locking and spool differentials. Each performs differently on and off the road. Generally, only...
  11. All About Paint

    In the early days of the automobile industry, painting was a slow process. It was applied manually and dried for weeks at room temperature by solvent evaporation. 1930 Packard Factory As mass production of cars made the process untenable, paint began to be dried in ovens. Nowadays, two-component (catalyzed) paint is usually applied by robotic arms and cures in just a few hours either at room temperature or in heated booths. (Note- That is why car paint can be waxed as soon as the new owner...
  12. The Right Size Wheel for Your Tire

    It is important to ensure your vehicle is installed with a properly sized tire. Each tire size is designed to fit a specific rim width. The correct rim width allows the tire sidewall to flex where the designers meant for the flex to occur. There is a wide range of tires that will fit a specific rim width. After you know what size range of tire will fit your wheels, you can pick a size based on aspect ratio and height of the different tire sizes. A rim that is too narrow in relation to the...
  13. Tire Primer

    The information found on a tire sidewall contains important information about the tire size, load capacity, weather ratings, and even government ratings for treadwear, traction and temperature. For illustration purposes, we will look at a 245/45ZR-20 tire (typical size for a Challenger R/T). Section Width The 245 indicates that the tire is 245 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified...
  14. Ignition Coils

    An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system. It transforms the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. Early gasoline internal combustion engines used a magneto ignition system, since vehicles did not have batteries. The voltage produced by a magneto was dependent on the speed of the engine, making starting difficult. A battery-operated coil, however,...
  15. Mufflers

    Since the beginning of hot rodding, enthusiasts have tinkered with their car’s exhaust system, particularly the mufflers, to get the “right sound.” A muffler’s job sounds easy enough- reduce exhaust volume to tolerable levels while allowing the sweet sounds of your ride to waft through the air. But this becomes a monumental task as horsepower increases. Engines build horsepower by pushing spent exhaust out of the tailpipe as fast as possible. As pistons furiously churn, exhaust velocity...
