Dodge Challenger Forum

How does the cost of leasing a Challenger compare to buying it, in terms of out-of-pocket costs? Or if you decide to buy a used Challenger, how much more will you save? And finally, what do those costs look like in the long run? These are important questions for buyers who want to carefully manage their automotive expenses over the years. It's hard to give one answer that covers all people and all situations. But the question can be divided into two parts: 1. An analysis of the hard costs...

Most of us know about windage trays, but what is their function and what exactly is “windage?” Simply put, windage is a force created on an object by friction when there is relative movement between air and the object. Windage loss is the reduction in efficiency due to windage forces. As it pertains to internal combustion engines, windage is the power loss caused by the friction of the oil in the engine coming into non-lubrication contact with its internal moving parts. For the most part,...

Pistons are one of the hardest working components of an internal combustion engine, where temperatures inside cylinders can reach over 1,800 degrees F. Early pistons were of cast iron, but there were obvious benefits for engine balancing if a lighter alloy could be used. To produce pistons that could survive engine combustion temperatures, it was necessary to develop new alloys such as Y alloy and hiduminium, specifically for use as pistons. A few early gas engines had double-acting...
