There is a “shade tree law” from the 1970s that states that computing capacity doubles every few years. In fact, computing capacity for the size of the computer or device has outstripped that by several orders of magnitude in the last five years. As evidence of that, we now see cell phones that were only

Performance Pistons

Piston manufacturers are introducing new performance pistons for all of these applications as well as refining existing piston designs to reduce weight, and improve strength, durability and ring sealing. Piston design and manufacturing used to be a relatively low-tech process. Now, with the aid of finite element analysis and other computer modeling techniques, many aftermarket

Align Honing Principles

If you ever want to get scared, check out what a crank looks like at high RPM. If you’re interested, the machine to do this with is called a Spintron. What you’ll see is a large, heavy, supposedly rigid chunk of steel squirming around like crazy. You’d swear any metal walking around that much would

Searching For The Complete Clean

Many shops have systems that work well for one but not so well on the other. Are there effective ways to clean both types of metal with one setup? The answer to that depends, in large part, on what you consider clean. Most shops have some type of cleaning equipment, whether it is an automated

All About The Alloys – Valve Seat Selection For High Performance Applications

We can’t make any sweeping generalizations about what kind of seats work best in a performance engine application because “performance” covers a lot of territory, everything from hot street engines with stainless steel valves to top fuel drag racing and NASCAR engines with titanium valves. Seat requirements vary depending on the application, what kind of

Reality TV puts ordinary people into difficult, often dangerous situations with the sole purpose of providing entertainment to millions of people. Except for the “entertainment” and “millions of people” part of the equation, that also sounds like just another business day. How often do you as a machine shop owner or engine rebuilder feel that

Connecting Rod Reconditioning: More to it than you might think

The connecting rod plays a vital role in the engine. But a connecting rod is under tremendous stress, with the weight of the piston sitting on top, changing direction thousands of times per minute. This continuous stopping and changing of direction combined with the weight of the piston and speed of the engine hammer on

Washington Way, President’s Agenda Daunting, But Is It Workable?

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
