  • Development of Airbags

    Airbags, like lap belts/shoulder belts, are a type of automobile safety restraint system designed to mitigate injury in the event of an accident. These gas-inflated cushions, built into the steering wheel, dashboard, door, roof, and/or seat of your car, use a crash sensor to trigger a rapid expansion of nitrogen gas contained inside a cushion, that pops out on impact to put a protective barrier between passengers and hard surfaces. The National Highway Traffic Safety Administration (NHTSA)...
  • Anti-Sway Bars

    An anti-roll bar (roll bar, anti-sway bar, sway bar, or stabilizer bar) is a part of many automobile suspensions that helps reduce body roll during fast cornering or over road irregularities. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness- its resistance to roll in turns, independent of its spring rate in the vertical direction. The first stabilizer bar patent was awarded to Canadian...
  • Dick Landy- Mopar Drag Racing Pioneer

    Dick Landy, a legendary drag racer and a major pioneer in Super Stock, Funny Car and Pro Stock, was also known for his innovative race cars and wild wheel stands. His nickname "Dandy Dick" came from his neat appearance in pressed white pants and jacket and long unlit cigar clenched between his teeth. Landy was among the drivers who popularized late-model Super Stock cars in the 1960s, campaigned the first Funny Cars in the middle of that decade and helped establish the popularity of Pro...
  • Need advice

    A new car dealer has a 2017 Mopar edition that was never sold. Less than 50 miles. Sticker was 63,000 reduced to 50,000. Question I have what is the better choice. A 392 scat pack or the Mopar edition? Seems the Mopar edition is around Hellcat price. I have a 14 Mopar edition, don't see many for sale. Depends on what I can get. Thanks
  • Mopar Engine Colors

    Automobile engines are usually painted bright colors, like red, orange or blue. This just isn’t for appearance. There is a practical purpose. Bright colors enable leaks to be spotted easily. Here is a list of engine colors (and paint codes) used by Mopar, from 1962 to 1971. Race Hemi Orange- Mopar P4120751 1962-1964 Max Wedge engines (413 and 426 Cross Ram) 1964-1965 426 Race Hemis Street Hemi Orange- Mopar P4349216 1966-1971 426 Street Hemis 1969-1971 High performance 383 and 440...
  1. "Grandfather" of the 2018 Dodge Demon

    Did you know that the controversial Dodge Demon name goes back 48 years? In 1970, the restyled Plymouth Valiant, named the Duster, was a massive success. Dodge immediately insisted on getting its own version. That car became the 1971 Dodge Demon. 1970 Plymouth Duster 340 Both the A-body Plymouth Duster and Dodge Demon were fantastic cars for the money (starting just over $2,100). The two cars were virtually identical, underneath. The attractive-looking Demon came with four optional...

    100th Article! Dodge Brothers

    Few people are aware of the important role that John and Horace Dodge played in shaping Detroit’s early auto industry, and of the story of a dynamic partnership formed between two enterprising brothers who remained inseparable throughout their lives. John (right) and Horace Dodge HUMBLE BEGINNINGS Born into an industrious but poor family, Dodge brothers, John (born in 1864) and Horace (born in 1868), received their mechanical training from working in their father’s machine shop, in Niles,...
  3. 3.6L Pentastar Engine

    A popular cost-conscious alternative for Challenger owners to the 5.7L and 6.4L Hemi engines is the 3.6L Pentastar engine. It replaced the 3.5L engine, in 2012, and is rated at an impressive 305 horsepower and 270 lb.-ft. of torque, with 90% of its torque available from 1,800 to 6,350 rpm. Performance from this modern 6-cylinder engine actually exceeds some small blocks from the first muscle car era. Before the first aluminum block was cast, the new Pentastar V-6 benefited from more than...
  4. A Look Back- The Rebirth of the Challenger

    The Challenger concept car, shown at the 2006 Detroit International Auto Show, was a big tease for Mopar fans. It was the answer to a hot rodders’ dream- the reincarnation of a 1970s Dodge muscle car! But, would it make it to production? See the 15:11 minute mark of the following video: Based on the success of the retro-inspired 2005 Mustang GT, Dodge looked at its parts bins and figured out how to use this stuff to create a modern-day Challenger. To accomplish this feat, Chrysler drew...

    Active Exhaust

    It’s a fact of life- cars make noise. Inexplicably, there are those in this world who build houses next to major freeways and then complain about the speed of the vehicles going past. There are those who build houses next to airports and complain about the excessive noise. Just as there are those people, there were those who decided that cars were too loud and needed to shut up! This presented car companies with a problem. Their engineers were telling them that for maximum efficiency,...
  6. 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...
  7. All-Wheel Drive

    Four-wheel drive, 4WD, 4x4 ("four by four"), or AWD ("all-wheel drive") is a four-wheeled vehicle with a drivetrain that allows all four wheels to receive torque from the engine simultaneously. While many people associate the term with off-road vehicles and sport utility vehicles, powering all four wheels provides better control in normal road cars on many surfaces, and is an important part in the sport of rallying. The first application of four-wheel drive, occurred in 1893. In 1937, the...

    Are Most Radar Detectors Useless?

    A radar detector is an electronic device that has been used by motorists, for decades, to detect if their speed is being monitored by police using a radar gun. It gave a driver sufficient warning to reduce his speed to avoid being ticketed for speeding. In a general sense, only emitting technologies, like Doppler radar, or LIDAR (pulsed laser light) can be detected. Visual speed estimating techniques, like ANPR or VASCAR cannot be detected in daytime. There are also no reports that piezo...

    Axle Ratios

    An axle ratio is the number of revolutions the output shaft or driveshaft needs to make in order to spin the axle one complete turn. The number is expressed in a ratio, which represents the number of teeth on the ring gear divided by the number of teeth on the pinion. For example, a vehicle with a 3.73:1 gear ratio means that the driveshaft will turn 3.73 times for each complete wheel spin. Many people simply refer to the axle ratio as 3.73, rather than express it as the ratio 3.73:1....
  11. Camshafts

    Camshafts are used to operate poppet valves. It consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes protruding from it, one for each valve. The cam lobes force the valves open by pressing on the valve, or on some intermediate mechanism, as they rotate. Camshafts can be made out of several types of material. These include: Chilled iron castings: Commonly used in high volume production, chilled iron camshafts have good wear resistance since the...

  13. Challenger- Concept to Production

    The planning and design of the Challenger concept car started in 2004. At that time, Chrysler’s Pacifica Studo was given the assignment to work with the exiting LX platform (i.e., Charger, Chrysler 300 and Magnum) to develop a 2-door, rear-wheel drive concept car. Many of the designers were musclecar guys and a new Challenger was proposed to be built around the 6.1 Hemi engine. There was a lot of conversation as to how much retro design features should be built into the car. Based on a...

    Chrysler Corporation in World War II

    Many are unaware of the vital role played by Chrysler Corporation in World War II. As Mopar enthusiasts, we should all be proud of its outstanding war record. In 1939, the U.S. military was laughable. The Army's own chief of staff, Gen. George C. Marshall, ranked it 19th in the world- one spot behind Portugal- in a report to the president. Roosevelt was about to change that- and America- forever. Decades of isolation and a global depression had created a nation unresponsive to the world...
  15. Chrysler’s Amazing Turbine Car

    Chrysler has always been an innovator in the car industry. Nothing, however, captured the imagination of the driving public and the spirit of the 1960’s space-age as the turbine car. The Chrysler turbine car was produced by Chrysler, from 1963 to 1964. Its body was made by the Italian design studio Ghia, and Chrysler completed its assembly in Detroit. Surprisingly, the Chrysler turbine engine program, that produced the turbine car, began during the late 1930s and created multiple...
