  • 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...
  • 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...
  • Window Tint

    Window film (a/k/a, tint) is a thin laminate film that can be installed to the interior or exterior of glass surfaces in automobiles. It is usually made from polyethylene terephthalate due to its clarity, tensile strength, dimensional stability, and ability to accept a variety of surface-applied or embedded treatments. Window films are generically categorized by their construction components (dyed, pigmented, metallized, ceramic or nano), by their intended use (automotive, marine or...
  1. 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...
  2. Car Weight Terminology

    There are three different terms that are used concerning a car's weight- Gross Vehicle Weight Rating (GVWR), Gross Vehicle Weight (GVW) and Curb Weight. So how are they different? A car’s Gross Vehicle Weight Rating (GVWR) refers to the maximum poundage your car can weigh to operate safely and without harm to its components. Put simply, it's the maximum weight before everything breaks. Manufacturers calculate this number by testing the structural integrity of your car’s suspension...
  3. 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...
  4. 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...
  5. Richard Petty- "The King"

    Richard Lee Petty is aptly named "The King." Over a racing career spanning 34 years, from 1958 to 1992, he was the first driver to win the NASCAR Cup Series championship seven times, while also winning a record 200 races, including the Daytona 500 a record seven times. Incredibly, he won a record 27 races (10 of them consecutively) in the 1967 season, alone. Statistically,he is the most accomplished driver in the history of the sport, and is one of the most respected figures in motor...
  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...

  9. 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...

  13. Harmonic balancer bolt

    Hey guys hopefully you can shed some light on something for me. I think my ext warranty company is trying to weasel out of paying. Ok so long story short my harmonic balancer bolt has backed out some how on its own and allowed the balancer to pull back and put little small shavings in my oil pan. When we pulled the balancer the tip of the crank was blueish purple. Have you ever heard of a bolt backing off like that.
  14. Tstats and Engine Temperature

    As we all know, the main purpose of a thermostat (tstat) is to maintain your Challenger’s engine at the ideal operating temperature and help produce fewer emissions. First, let’s talk about how a tstat functions and then why racers install low temperature ones. Basically, the thermostat starts at a closed position when you start the engine to help it reach operating temperature. While the engine is running, the coolant temperature slowly rises, making the thermostat begin to open. The...
