  • History and Applications of Carbon Fiber

    Carbon Fiber is a polymer and is sometimes known as graphite fiber. It is a very strong material that is also very lightweight. Although carbon fiber is five times stronger and twice as stiff as steel, it is lighter than steel; making it the ideal manufacturing material for many parts. These are just a few reasons why carbon fiber is favored by engineers and designers for manufacturing. Carbon fiber dates back to 1879, when Thomas Edison baked cotton threads or bamboo silvers at high...
  • The Advantages & Disadvantages of Lowering Your Car

    Cars come with conventional-size and strength springs that help it deal with potholes and bumps on the road. Manufacturers have spent considerable time and money to come up with just the right suspension components. Nevertheless, it has become fairly common for car owners to modify their cars’ suspensions to make them ride lower. Usually aesthetics are one of the most important reasons for reducing ride height- many people prefer the appearance of a lower car- but there are other...
  • 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.

  1. 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...
  2. 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...
  3. 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...

  6. 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...
  7. 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...

    I've got a 2014 billet silver with the red stripe rally redline, and was wandering would it be better to keep the paint scheme and stripe the same to keep it original or change it up a little i haven't seen 1 like mine and only know of 1 other one in my area. thats black with the red stripe .i plan on lowering it and tinting the windows and possibly changing the stripes, and maybe going a little darker paint like a gray with black stripes but not the same as what i have now.i know theres not...
  9. 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...
  10. 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.
  11. 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...

  13. 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...
  14. Engine Dyno vs. Chassis Dyno

    What's the difference between running an engine on an engine-dyno, or, as installed in the car, on a chassis-dyno? Most chassis dynos extrapolate an engine's power and torque based on vehicle inertia. Many variables can affect chassis dyno results. It's a great convenient tuning aid, but you can't directly equate the reported torque and power numbers back to engine dyno results, or even the results obtained from two different chassis dynos. Operator experience is critical for obtaining...
  15. Hemi Heads

    In recent years, Dodge has produced four different Hemi heads. Here is a brief description of each. In 2003, the 5.7 Hemi received the first, followed in 2005 by the 6.1 hemi design. In 2009 and 2011 respectively, the 5.7 Hemi Eagle and 6.4 Hemi Apache head appeared along with Variable Valve Timing (VVT) and the larger 392-inch engine. As the engines got larger, the heads improved with the help of larger valve sizes and improved ports. As cams got bigger, the beehive springs got more...
