  • What is a CVT Transmission?

    Some say you can't teach an old dog new tricks. But the innovative continuously variable transmission (CVT), which Leonardo da Vinci conceptualized more than 500 years ago is now replacing planetary automatic transmissions in some automobiles. Since the first Toroidal CVT patent was filed in 1886, the technology has been refined and improved. Today, several car manufacturers, including General Motors, Audi, Honda, Hyundai and Nissan, are designing their drivetrains around CVTs. Cars with...
  • 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...
  • 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...
  • 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...

  2. 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...
  3. Safety Regulations/Equipment for Racing

    If you plan to enter your vehicle in any competition sanctioned by the NHRA, your Challenger is going to have to pass a series of pre-race inspections for the required safety equipment. These requirements get more stringent as the expected horsepower and speeds increase.The SFI Foundation sets the standard for quality assurance in the vast majority of aftermarket and performance products. Basic Safety The basic safety stuff for the street legal classes is pretty simple. You’ve got to have...
  4. Dick Landy- Mopar Drag Racing Pioneer

    Dick Landy, a legendary drag racer and a major pioneer in Super Stock, Funny Car and Pro Stock, was also known for his innovative race cars and wild wheel stands. His nickname "Dandy Dick" came from his neat appearance in pressed white pants and jacket and long unlit cigar clenched between his teeth. Landy was among the drivers who popularized late-model Super Stock cars in the 1960s, campaigned the first Funny Cars in the middle of that decade and helped establish the popularity of Pro...

    Modern Hemi Engines

    Modern Hemi production began in June 2002 at the Saltillo plant in Mexico. The first-generation 5.7 liter produced up to 350 horsepower at 5,600 rpm and 375 lb-ft of torque (4,400 rpm)- one horsepower per cubic inch- just like the legendary 426 Hemi. It was smaller, more powerful, and cheaper to build than the LA-series 360 V8 and the "Next Generation" 4.7 liter V8 it replaced, but produced more power and torque. It hooked up to the Mercedes 5-speed automatic, Chrysler's 5 and 6-speed truck...
  6. Driving Dangerously in Motown- 1900-1930

    The first gasoline-powered vehicle driven on the streets of Detroit was built by engineer Charles Brady King in 1896. It went as fast as 20 mph, which was described in the newspaper as "tearing along the street at a lively rate, dodging people and teams." The transition from the horse age to the motorized age would prove to be very dangerous. At first speeding vehicles were not a big problem, with only a few of them on Detroit streets, but the situation grew serious quickly. As early as...
  7. 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...
  8. Chrysler’s Amazing Turbine Car

    Chrysler has always been an innovator in the car industry. Nothing, however, captured the imagination of the driving public and the spirit of the 1960’s space-age as the turbine car. The Chrysler turbine car was produced by Chrysler, from 1963 to 1964. Its body was made by the Italian design studio Ghia, and Chrysler completed its assembly in Detroit. Surprisingly, the Chrysler turbine engine program, that produced the turbine car, began during the late 1930s and created multiple...
  9. 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...
  10. 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...
  11. 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...

  13. 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...
  14. 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.
  15. 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...
