  • 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...
  • Drag Racing Primer- Tips with Street Tires

    Here are some drag racing tips to make your trip to the drag strip safe and successful. Before you arrive at track Remove the floor mats, child seats (if applicable) and other non-essential cargo. Every bit of weight you remove can help. Try to plan so you have about ¼ tank of fuel when you arrive. Extra fuel adds weight and you won’t need more than ¼ tank. Don’t show up with your tank on empty. The fuel is usually expensive at the track and you don’t want to be “running on fumes.”...
  • The Meaning of "Mopar"

    Short for the Chrysler Motor Parts Corporation, Mopar made its first appearance in the late 1920s and became its own brand in 1937. The name Mopar was created by a committee to market cans of "Chrysler Motor Parts" antifreeze. From there, the Mopar catalog expanded to include waxes, cleaners, filters, engine parts and more. Now, in its 81st year, Mopar encompasses the full line of Fiat Chrysler Automobiles parts, accessories, and customer service, including Fiat and Alfa Romeo brands...
  • High Impact Paint

    In the late 60s/early 70s, Dodge was already offering some of the hottest cars of the muscle car era- awesome machines like the Hemi Challenger and 440 Six-Pack Super Bee. Designers, however, decided to rev up the cars’ visuals to match, creating a far-out assortment of vibrant exterior paint colors. These special colors (a $15 option) generated a big buzz in the showrooms and launched an industry trend. The color palettes used by all the automakers were opened up, giving paint designers...
  • World's Fastest Hellcat

    When Dodge introduced the Challenger Hellcat back in 2014, it claimed that in stock form with the automatic transmission, it could cover the quarter mile in just 11.2 seconds. With drag radial tires, the time could be reduced down to the 10.80s The first Hellcat owner to break into the 10-second range was Jay Gustafson, who ran a 10.997 a few years back, making his Challenger the quickest stock Hellcat car in the world, but Canadian racer Jim Benko recently ran a 10.937, on November 11,...

    Nitrous Oxide

    Juice. Squeeze. Laughing gas. Nitrous oxide has many aliases. It can inject a healthy dose of horsepower into an engine, via direct port, carburetor/throttle body plate, air intake tube or, air cleaner injection, to give a race car the winning edge at the track. In racing, nitrous oxide (often referred to as just "nitrous") allows an engine to burn more fuel by providing more oxygen than air alone, resulting in a more powerful combustion. The gas is not flammable at a low...
  2. Paddle shifters

    Paddle shifters, once exclusive to race cars and exotic sports cars, like the Ferrari F430, are now becoming commonplace on performance cars with automatic transmissions. This is because manual transmissions are going away faster than the landline telephone. Critics of automatics say that they take the passion and command out of driving. Paddle shifters, however, bring some of that joy and control back by allowing drivers to manually shift an automatic transmission with steering-wheel or...
  3. Pro Stock Record Holders

    Pro Stock quarter mile drag racing times have dramatically decreased over the decades, since the class was established in 1970. This has been the result of tremendous advances in technology. To determine who is the fastest competitor, forty-nine years ago, NHRA instituted the Mello Yello Drag Racing Series. The champion is determined by a point system where points are given according to finishing placement and qualifying effort. The season is divided into two segments. After the first 18...
  4. Ralph Gilles- A Real Mopar Guy

    Mopar enthusiasts owe the fantastic array of performance models to Ralph Gilles, Head of Design for Fiat Chrysler Automobiles. We are truly fortunate to have a cool car guy in charge. Gilles, as a boy living in Quebec, was drawing concept vehicles at the age of eight. When he was fourteen years old, his aunt sent one of his sketches to Chrysler Chairman Lee Iacocca. A reply came from K. Neil Walling, Chrysler's design chief at the time, suggesting he attend one of three design schools....
  5. Ronnie Sox- A Tribute to "Mr. Four Speed"

    Ronnie Sox is one of the greatest Mopar drag racers. Like many who eventually became professional racers, "The Boss," grew up around cars, raised in the shadow of his family’s Sinclair service station. As soon as he was old enough to drive, Sox began competing in drag races, sponsored by the Police Club of Burlington, NC, at a local airport. In the early days, Sox didn’t even own a car and used his father’s 1949 Olds. From these humble beginnings, Sox would go on to become what many...
  6. Slicks & Drag Radials

    Drag radial street-legal tires had their origin in racing. Originally, race cars used “racing slicks”- a type of tire with a smooth tread. The first production "slicks” were developed by M&H Tires in the early 1950s for use in contact patch to the track and maximized traction for any given tire dimension. Slicks were also used on road and oval track racing where steering and braking require maximum traction from each wheel. Slicks, however, are not suitable for use on street cars which...
  7. Superchargers vs. Turbochargers

    When designing an engine to pull in more than atmospheric pressure, engineers often turn to forced induction. It’s one of the fastest ways to add significant power to almost any engine, and there are two prevalent ways it can be done: supercharging and turbocharging. But, which is better? Both are different in terms of how they work, performance and cost. Both operate on the principle that the more air you can get into your engine, the more power your car will make. Supercharging is old...

  9. The Origin of Scat Pack

    The Dodge Scat Pack was originally introduced in 1968 with the Charger R/T, Coronet R/T, Dart GTS, and Super Bee. In order for a car to enter the Scat Pack it had to be capable of running the quarter mile in the 14s (14.99 or faster). Mainly a marketing term, Scat Pack cars got twin bumblebee stripes and special decals. It became legendary in the enthusiast community and symbolized one of the most feared groups of street machines every to rumble from stoplight to stoplight. In the early...
  10. 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...

    Tire Speed Ratings

    Tire speed ratings first originated in Europe in the 1960s, as a way to make sure increasingly faster vehicles were equipped with appropriate safe tires. These early speed ratings set the foundation for the current speed rating system used by the DOT and tire manufacturers. Every tire approved for highway use by the Department of Transportation comes with a particular speed rating. The speed rating is a letter corresponding to the maximum safe speed at which a tire can be driven, as...
  12. What is a CVT Transmission?

    Some say you can't teach an old dog new tricks. But the innovative continuously variable transmission (CVT), which Leonardo da Vinci conceptualized more than 500 years ago is now replacing planetary automatic transmissions in some automobiles. Since the first Toroidal CVT patent was filed in 1886, the technology has been refined and improved. Today, several car manufacturers, including General Motors, Audi, Honda, Hyundai and Nissan, are designing their drivetrains around CVTs. Cars with...
  13. What is Hydroplaning?

    The term hydroplaning is commonly used to refer to the skidding or sliding of a car’s tires across a wet surface. Hydroplaning occurs when a tire encounters more water than it can scatter. Water pressure in the front of the wheel pushes water under the tire, and the tire is then separated from the road surface by a thin film of water and loses traction. The result is loss of steering, braking and power control. Rubber tires have tread (grooves) that are designed to channel water from...
  14. Why Do Hemi Engines Have Dual Sparkplugs?

    Each cylinder on a Hemi engine has an ignition coil pack over one spark plug, and a regular plug wire connected to the other spark plug. Further, the coil pack also has a plug wire attached to it that extends to the opposite cylinder bank. Each cylinder shares a coil pack with another cylinder. Each of the two plugs on a given cylinder is fired by a separate coil. One plug has a coil directly attached, and the other is fired via an ignition wire connected to a coil located on another...
