Performance Connecting Rods
The connecting rods are a vital link between the pistons and crankshaft. They connect the reciprocal motion of the pistons to the rotational motion of the crank. The weight of the rods is important because it affects the reciprocating forces inside the engine. Lighter is usually better because less weight means faster throttle response and
Diesel Drag Racing, Compression Ignition Engines Smoke The Strip
It is one of the purest forms of American motorsports. One guy pulls up next to another guy at the starting line and revs the engine. A simple glance over, a nod and a green light. In a fury of sound and smoke, the two racers take off down the straight stretch of pavement. If

Performance Drag Racing Heads
A quarter-mile strip of asphalt is not a great distance. But drag racing isn’t about distance. It’s about time. The car that reaches the finish line first wins the race. But the car that wins isn’t always the fastest car or the quickest car. It’s usually the car that runs with the most consistent elapsed
Drag Racing Engines
From the early days of drag racing up until the recent past, racers built everything for their cars themselves, from the engines and chassis to the shop equipment. Most racing teams pulled their racecars to the track behind the family station wagon or pickup truck. The personalities who participated in the sport were as colorful
Which Cranksfaft Meets Your Racing Needs Best?
There are a lot of racing crankshafts in the automotive aftermarket today. You’ll find a wide variety of styles, strokes, weights and price ranges from which you can choose. The question you need to be asking is which crank is “right” for the engine you’re building? The answer to that question depends on several things
Crankshafts:Stock and Performance
The crankshaft is the working arm of the engine. All the force generated by combustion and the downward motion of the pistons is focused on the crank throws. The leverage effect of the force exerted on the crank journals twists the shaft and converts the up-and-down reciprocating motion of the pistons into rotational motion of
