Engine Balancing: Old School Experience Meets New Technology
The one fact that has held true from the first engine built till today is you must have balance to hold things together and not vibrate apart. I am a Performance Engine Technology Instructor at Daytona State College, therefore I must give you a short applied physics lesson first. The force of a rotating object
Smoothing Out The Stress
We’ve all heard (and probably used) the term “harmonic balancer.” I always get a chuckle when I hear this term used so freely by educated gear heads.

Understanding The Differences, Challenges Between Crankshaft Position Sensors
I have suggested to you to watch for this and make sure that you have that, and encouraged you to be certain that it is indexed to this position and so on. But I don’t believe that I have ever written about watching out for damaged as-cast reluctor rings, spark triggers or whatever other name

Evolving Crankshaft Designs and Applications
In the early days, a crank didn’t have to be very sophisticated or strong because most engines were an inline design, and the loads and speeds were relatively low. Fast forward to today. The evolution in engine technology, power and performance has led to a whole new generation of performance crankshafts that are a mechanical
Balancing And The Bottom Line
Balancing, once considered to be important in this industry only to performance engine builders, has lately become a sought-after service in some segments you may never have considered. Yet good-old-fashioned engine balancing remains an important profit center in many machine shop operations. If the engine components (pistons, rods and crankshaft) aren’t in balance you’ll experience

Head and Block Surface Prep Most cast iron V8 heads and/or blocks usually don’t require anything more than a good cleaning. They are not as likely to warp as straight-six or aluminum heads or blocks.

Time for Chains: Stock and Performance Timing Sets
Timing chains and gears are engine parts that are usually replaced when an engine is rebuilt. Over time, gear teeth wear and chains stretch. This can cause noise, retarded valve timing (and ignition timing if the engine also has a cam-driven distributor), and a noticeable loss of performance and fuel economy. A new timing chain,
