General Challenger

  • Phillips Head Screw

    The origin of the lowly Phillips screw is an interesting one. The history of metal fasteners go back to the 15th century. British toolmaker Joseph Whitworth devised the first screw in 1841 and American engineer produced the same in 1864. Screws were very hard to produce, however, and required the manufacture of a conical helix.. The brothers Job and William Wyatt found a way to produce a screw on a novel machine that first cut the slotted head, and then cut the helix. Though their business...
  • 100 Anniversary Edition Challenger.

    Hello, I have a 2014 Anniversary Edition Challenger. purchased it new in 2014. Since then, I have NOT seen any other anniversary models on the road, except I did see a 2014 anniversary Charger. Everywhere I go, a lot of Mopar guys ask me, What model is your car. In the winter time, its kept in the garage, covered and I drive my Ram. Which is also awesome. Several people at car shows ask if I want to sell it. The answer is, always, NO. I love this car. I have under 30,000 miles. Now, I've...
  • 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...
  • Factory Paint Process

    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...
  • 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...

  2. 226 mm / 8.89 in. LSD CV Axle Shafts only currently available through Mopar in North America.

    These axle shafts required for the 2008 - 2014 LSD rear wheel differentials are not currently available through Cordone (remanufactured) and despite catalogue indications to the contrary not even produced by Trakmotive / SurTrack / GSP North America. East Coast Mopars and others providing the Getrag swap pkgs. are using axles provided by Mopar, at similar pricing to the dealerships. I can't even find used axles through auto wreckers in western Canada. Sharing this so others don't waste their...
  3. Camera Technology

    Not so long ago, drivers had only the view provided by the auto’s windows, as well as their own judgment, to drive their vehicles. However, no matter how experienced and skilled a driver was, there was always the risk to misjudge the distance between the car and curb while parking or not to notice other auto’s maneuver on the road, especially when it was in the blind zone. All these led to numerous accidents in which no one could prove whose fault it was. The good news is that if you own a...

  6. The History of Car Antennas

    Automotive antennas have evolved since their introduction in the 1930s. Once tacked on as optional equipment, they are now designed into the car as an indispensable accessory. Several different approaches have been used to improve performance while making the antenna attractive, including embedded windshield versions and electric hide-away styles. The First Antennas In the 1930s, car antennas were incorporated into the radio body, as most stations were in the AM band, which required a...

  8. Auto-Stop/Start Technology

    Since the Obama Administration finalized standards in 2012, to encourage the automotive industry to reach a 54.5 miles per gallon corporate fuel economy average by 2025, manufacturers have been employing every means possible to squeeze another mile out of a gallon of gasoline. A combination of aerodynamics, weight savings, electrification, hybrid technologies and advanced engine management software has gone a long way, but it doesn’t take a rocket scientist to understand that you save a lot...
  9. Rocker Arm Ratios

    Many have heard the term rocker arm ratio mentioned when talking about an engine. But, do you know what rocker-arm ratios are, and how different ratios can affect an engine’s performance? To start with, an engine is just a sophisticated air pump. The amount of power this “pump” delivers is directly affected by the amount of air ingested and expelled by the engine. Increase the amount of air flowing through the pump, and you can increase power output. While an engine is running, air is pulled...
  10. Electric and Hydrogen-Powered Cars

    Stellantis is finalizing its 5-year and 10-year plans. According to Automotive News Europe, newly appointed Alfa Romeo CEO Jean-Philippe Imparato told Italian journalists, during a roundtable event, that all future vehicles from the company would be electrified. They will be built on a new platform known internally as the STLA large-vehicle architecture that will be shared across brands under the Stellantis umbrella. Tim Kuniskis, in a recent Autoweek interview, was quoted as saying, “I...
  11. 0% financing

    Wondering if anyone has any insight or thoughts into the current offer of 0% a.p.r. for 72 mos. I wonder, will this be a one-time deal? I've literally wanted one of these cars since 07, when they came out. For one reason and another over the years, I've never yet pulled the trigger. Got on this forum several years ago, to follow the latest news and info. I've lurked, enjoyed your guys' posts and kept on dreaming of the day. I've said for years, "why can't they offer 0% on the damn...
  12. How Rev Limiters Work

    Simply put, rev limiters restrict the maximum speed an engine can achieve. They are there to prevent an engine from damaging itself by extending beyond its limits. Any engine is only designed to be able to function up to a certain speed, which is measured in revolutions of the crankshaft per minute. Out of the factory, the rev limiter is set at the point the engine’s maker is happy for it to rev to on a regular basis. It’s not to be confused with the redline, although it can sometimes be...

Before The Show The Build- Restoring or Modifying Your Car Some owners rack up their credit cards doing things to their cars for the sole purpose of “checking off that box” on the judges’ score sheet. The funny thing is,...
  14. Burnout Primer

    All drag racers spin their wheels in a burnout before every race. The burnouts may seem to be pure show-boating, but there are real reasons behind all the smoke and noise. Burnouts before a drag race serve to heat the tires of the car, softening the rubber, providing more traction for the start of the race. The burnout also removes any debris from the tires. Spinning the wheels leaves a layer of rubber on the road surface, providing better traction in the future. The burnout is crucial for...
  15. Ethanol Fuel Mixtures

    The question frequently comes up, “Are E10 and E85 fuels harmful to my engine?” Here is everything you wanted to know about the chemical compound ethanol that is added to gasoline. Ethanol is used as an “oxygenate” and is added to fuel to help reduce hydrocarbon emissions that cause air pollution. It is highly refined beverage (grain) alcohol, approximately 200-proof, that can be produced from natural products such as corn, sugar cane and wheat. New technology allows ethanol to be made...
