  • 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...
  • 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...
  • High Impact Paint

    In the late 60s/early 70s, Dodge was already offering some of the hottest cars of the muscle car era- awesome machines like the Hemi Challenger and 440 Six-Pack Super Bee. Designers, however, decided to rev up the cars’ visuals to match, creating a far-out assortment of vibrant exterior paint colors. These special colors (a $15 option) generated a big buzz in the showrooms and launched an industry trend. The color palettes used by all the automakers were opened up, giving paint designers...
  1. History of Automotive Paint

    Producing an automobile mostly comes down to physics and engineering, but, like chrome, paint mostly comes down to chemistry. During the rapid development of the motorcar in the late 19th and early 20th centuries, the complex chemical compounds and sophisticated techniques employed by today’s carmakers simply didn’t exist. Some early cars were hand-painted. Like, with a brush. Even as automotive production grew, paint with a varnish-like composition was the most common finish, applied in...
  2. Meaning of R/T

    Long before SRT, R/T was top dog of Dodge performance. If your Mopar had that two-letter badge in the grille, it was enough to send even the baddest of would-be street racers packing. These cars would go toe-to-toe with SS and GT cars all day long, often besting them from stop light to stop light and on the drag strip. What does R/T actually mean, though? What equipment did it entail a car came with? R/T is an acronym that stands for Road and Track. When it first appeared in the late 1960s,...
  3. What is a Stroker Engine?

    Internal combustion engines are commonly referred to by their displacements, whether its old-school cubic inches or more modern CC and liters. An engine's displacement is calculated using the diameter of its cylinders and the length of its crankshaft stroke to determine the volume of each cylinder. That volume is multiplied by the number of cylinders to get the total displacement. There are two ways to increase the displacement of the engine in your car. You could bore the cylinders to a...
  4. Exhaust Backpressure

    This YouTube video explains exhaust backpressure, exhaust scavenging and turbo pressures.
  5. How does MDS Work?

    The following Motor Trend article, describes in detail, how the MDS system works. What Is Hemi MDS? (motortrend.com)
  6. Pulling Fuse #2 and Adaptives

    HERE'S WHAT HAPPENS WHEN YOU PULL #2 FUSE (older Challengers) Pulling Fuse F2 resets: All PCM DTCs erased. All OBD2 monitor results erased. All "long term fuel trim adaptive" values reset to Zero. Long term Fuel Adaptive trim will now start over the next 100 engine start cycles. Cycle the headlights as described above will create a Short Term Fuel Adaptive trim table over the next 50 start cycles. Driver Adaptive? Driver Adaptive and related fuel table trim is probably the least...
  7. 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...
  8. New LED's for my 2009 R/T. Pictures do not do it justice!

    Well I've been waiting around to win the lottery so I could afford some LED tail lights. So just for giggles I bid 400 bucks for a set on eBay and the offer was accepted. I ordered my three layer center decal in advance so I put it on before the lights. It was a little tall so I just trimmed it before I took off the paper. I always wanted a blacked out rear end but I never liked those covers that went over the stock lights of the 2008 through 2014. I purchased the smoke set and it does not...

    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...
  10. 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...
  11. Li-Ion Batteries

    We are now entering the electric car age. These vehicles are powered by Li-Ion batteries. This type of battery is energy dense and durable. However, it can also be unstable and prone to catching fire under certain circumstances. But not all Li-Ion batteries are suited for vehicles. How Do They Work? Lithium ions store the energy by creating an electric potential difference between the negative and positive poles of the battery. Those are isolated using a separator material to prevent...

    Prochargers

    In a previous article, superchargers and turbochargers were discussed in detail (see link, below). Superchargers vs. Turbochargers | Dodge Challenger Forum Anyone who goes to the track, or watches the cable TV show, Street Outlaws, knows that many knowledgeable racers are going to prochargers. In fact, Ryan Martin, switched his Fireball Camaro from twin turbos to prochargers. Watch his interview at the 2:30 minute mark. Prochargers, superchargers and turbochargers are all different...
  13. 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...
  14. Wind Tunnels

    When most people think of wind tunnels, an aerospace tunnel usually comes to mind. This helps designers and engineers understand how aircraft will behave during various flight conditions. Automotive wind tunnels are usually very similar to aerospace tunnels, but they often feature a rolling floor that lets test engineers simulate a car driving on the road at various speeds. What are Wind Tunnels? Wind tunnels are large tubes with air blowing through them which are used to replicate the...
