  • Evolution of Hood Scoops

    Back in middle school science class, we learned that in order to make fire, you need three ingredients: fuel, ignition and air- or, more specifically, oxygen. You’ll also remember that cold air is denser than hot air, putting more oxygen in the same amount of volume. While the modern internal combustion engine does a fine job of delivering fuel and ignition, that cold air part becomes tricky as you try to route fresh air from outside through a hot engine compartment. In response, in the late...
  • how to wire up the solenoid when doing a 6.4l manifold to a 5.7l swap

    a lot of questions have been fielded about how to wire the msd window switch for the 6.4l short runner tuning valve. i sat down on a recent vacation and worked my way backwards to figure how to painlessly wire this system so it works close to what the factory intended. i have acess to all the service information from FCA being that i work for them. get the connector from chrysler for the solenoid. DON'T buy the circuit boss, it is confusing and unnescessary. the red wire from the window...
  • 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...
  • Types of Tires

    Tires come in many treads, sizes and performance characteristics. Here is a primer on the basic car tire categories and some popular consumer choices. Extreme Performance Summer Hyper-focused on extreme dry grip, but gives up wet traction, comfort and tread life to get it. Not to be driven in near-freezing temperatures, in snow or on ice, or at high speeds in deep standing water, these specially tuned tires combine big-block tread designs with aggressive tread compounds and reinforced...
  • 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
  1. 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...
  2. Dim to Bright- Headlight Technology

    From its humble origins, the headlight has evolved from what was considered an accessory of the 1900s to a necessity safety feature (half of all deadly accidents occur at night). Since its first generation, headlights have traveled a long way from a simple flame to a high-tech laser. Carbide Headlights The first vehicle headlamps were officially introduced during the 1880s and were based on acetylene and oil, similar to the old gas lamps. Originally developed for mining purposes, Carbide...
  3. Exhaust Headers

    A component of any car or truck engine is an exhaust manifold for each bank of cylinders .In most production engines, the manifold is a cast iron assembly designed to collect the exhaust gas from two or more cylinders into one pipe. Engineers like cast iron because of its heat management properties and its superior longevity over any other type of exhaust outlet design. They also use the least metal, occupy less space and have the lowest production cost. Although these design restrictions...
  4. 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...
  5. Evolution of Racing Stripes

    Racing stripes are usually a “must have” for owners of muscle cars. These stripes, originally called “go faster stripes,” first appeared on Cunningham race cars in 1951. Two parallel blue stripes ran from front to rear in the center of the white car body. Their main purpose was to help spectators identify the cars during races. They evolved from the traditional FIA registered U.S. Racing color of a white body and blue chassis, which dated from when racing cars had the chassis exposed. The...
  6. Tips for Car Shows

    Winning a car show is great satisfaction. The real reward, however, is having a group of knowledgeable people say that they respect your style, taste and hard work. If you’re one of those people that take car shows seriously, here are a few tips that might help you win. 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,...
  7. Ignition Coils

    An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system. It transforms the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. Early gasoline internal combustion engines used a magneto ignition system, since vehicles did not have batteries. The voltage produced by a magneto was dependent on the speed of the engine, making starting difficult. A battery-operated coil, however,...
  8. 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...
  9. 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 85th year, Mopar encompasses the full line of Fiat Chrysler Automobiles parts, accessories, and customer service, including Fiat and Alfa Romeo brands...
  10. EV Charging & Battery Life

    Electric cars need to be recharged frequently for efficiency. However, charging an electric car is a much different experience than refueling a gas or diesel vehicle. Instead of a few minutes, charging an EV can take anywhere from 30 minutes to over 30 hours. This is because there are actually three levels of electric car charging. Levels of Charging NeoCharge provides a breakdown of the three levels of EV charging. Each level of charging is defined by the amount of voltage, which...
  11. 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...

    Windshield Dots

    The small black dots on a car windshield are called frits, which are black painted enamel that’s baked onto the surface of the glass. Modern cars have a windshield bonded to the frame. He described how the windshield is bonded using a strong and long-lasting urethane adhesive, which makes the windshield a structural component of the vehicle’s body. The frits “provide a secure point of contact between the glass, urethane adhesive, and windshield frame. Essentially, the small black dots help...
  13. 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...
  14. 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...
  15. Crash Test Dummies

    A crash test dummy is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers,automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash. Modern dummies are usually instrumented to record data, such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision....
