  • 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...
  • Dual Clutch Transmissions

    Most drivers know that cars come with two basic transmission types- manuals, in which the driver changes gears by depressing a clutch pedal and using a stick shift, and automatics, which shifts using clutches, a torque converter and sets of planetary gears. But there's also something in between that offers the best of both worlds- the dual-clutch transmission- also called the semi-automatic transmission, the "clutchless" manual transmission and the automated manual transmission. In the world...
  • Hood Pins

    Hood pins are used as a secondary restraint for the hood and are attached by a pin and plate drilled through the hood. They were originally made for the racetrack to keep hoods buttoned down at high speeds, but found their way onto muscle cars of the late 60s/early 70s. Hood pins (two per hood) were most prevalent on Dodge and Plymouth muscle cars of that era (e.g., Challengers, ‘Cudas, Road Runners, Daytonas, GTXs, Super Bees, etc.). They were, primarily, a styling element used to give a...
  • Shock Absorbers

    An automobile shock absorber is basically a hydraulic piston that absorbs and dissipates vibration using spring-loaded check valves and orifices to control the flow of oil. The first production hydraulic dampers, to act on the main leaf spring movement, were probably those based on an original 1908 concept by Maurice Houdaille. One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the...
  1. "Grandfather" of the 2018 Dodge Demon

    Did you know that the controversial Dodge Demon name goes back 50 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...
  2. 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...
  3. 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...

    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,...
  5. 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...
  6. 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...

  8. 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,...
  10. 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...
  11. 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...

    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...
  13. 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...

    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....
  15. Blind Spot Monitoring

    What is Blind-Spot Monitoring? Blind-spot monitoring one of those features we didn’t know we needed or wanted until carmakers began offering it. Volvo was the first, incidentally. It offered its Blind Spot Information System (BLIS) for the S80 in 2005. BSM is just what its name implies. It keeps an eye on the space just off the rear quarter areas of your vehicle. These blind spots can hide a vehicle approaching in an adjacent lane because many drivers improperly set their car’s outboard...
