Engine Bearings: Stock & Performance
The importance of the engine’s bearings can’t be over-emphasized. The bearings support the crankshaft and connecting rods, and in pushrod engines also the camshaft. The bearings provide a surface for the friction-reducing oil film that allows the parts to spin without rubbing metal against metal. It’s a tough job because of the high loads created
The Mid-range Diesel Engine Market
The diesel engine market is a very complex one, but it can be broken down into three basic categories: light-, medium- and heavy-duty. These categories could then be broken down further into on-highway, off-highway and agricultural. In 2004 roughly 1.5 million new diesel engines were produced in North America, a whopping 79.6 percent of which
Coretalk: AERA EXPO 2005 Set For Las Vegas Hilton In April

Coretalk: GM, DaimlerChrysler Join Forces To Produce Hybrid Automobile Engines By ’07
Although financial terms of the agreement weren’t disclosed, the collaboration is likely to involve an investment of hundreds of millions of dollars between the automakers. The first of the vehicles is to debut in 2007 – when Toyota has said it hopes its hybrid model sales will total several hundred thousand worldwide. GM, which has
PERA’s Core Corner: Trying To Make Sense Out Of Detonation Sensors
Here it is the New Year and I’m sure many of us have gone through the challenge of making resolutions to lose weight, quit smoking and so on and so on. We’ll look back 3 months from now and try to make sense of how our resolutions got lost in the shuffle. This month we
Tractor Pulling: It’s Not Your Granddad’s John Deere Anymore
Tractor pulling has been with us for as long as there have been tractors. Farmers used to pull their horses, mules or oxen and, just as today, each bragged that he had the biggest and strongest. Today, at the top echelons of pulling, the technology is equal to anything else in motorsports. Although you won’t
What’s Hot In Performance – Cams, Lifters & Rockers
The camshaft is really the heart of every performance engine because the cam defines the engine’s breathing potential, its torque curve and peak horsepower. The camshaft controls when the valves open, how quickly they open, how far they open (with some help from the rocker arms), how long the valves are held open, and when
Not So Stock: NASCAR Motors and Their Street Counterparts
The engines in NASCAR’s newly introduced Strictly Stock class of stock car racing in 1949 were literally stock, right off the dealer’s showroom floor. Today, they’re anything but. So what happened? Evolution. Like any sport or industry, evolution has moved NASCAR racing to where it is today, a multi-million dollar business. The engines, called ‘motors’
PERA’s Core Corner
I am convinced that the 4.6L Ford SOHC V8 engine casting component proliferation is attempting to compete with the children’s movie “The Never Ending Story:” it just keeps changing as it goes along for no apparent reason. However, what we are going to look at today is more of a James Bond mystery since no
New Technology:Advances in Engine Building Equipment
How has racing changed your engine building business? No, it’s not a hypothetical, industry-generic question; in this case, it’s directed at every reader of this magazine. A strange question? It may seem to be. If you race – or build motors for racers – it’s probably an easy one to answer. But if you stay
Building Drag Racing Cylinder Heads
One thing every drag racer wants is to go faster – even bracket racers. There are lots of ways to shave tenths of seconds and even whole seconds off an elapsed time. It all comes down to how much money the racer is willing to spend in his quest for speed. One way to go
When Old Dogs Learn New Tricks
When Jay Steel was introduced to the assembled throng at last spring’s AERA International Expo 2003 as the winner of Engine Builder’s 2003 “Machine Shop of the Year” award, he was intimately involved with the down and dirty business of rebuilding and restoring all manner of antique engines. His shop’s lineage descends directly from the
In Search Of New Markets, Mike Jeffries
Looking for new markets is one of the toughest things we do, so every time the phone rings we listen for an opportunity. Most of what we find is suspect, but over the past 12 months we have rebuilt a number of compact diesels and sold a number of rebuild kits. As a result we
The New Sport Compact Market
The most popular nameplates are imports such as Honda, Acura and Mitsubishi, but coming on fast are Nissan, Toyota, Mazda, Subaru and Volkswagen – plus domestic models such as Ford Focus, Dodge Neon and even Chevy Cavalier. Nobody is abandoning the small block Chevy or any of the other V8s that have traditionally been the
High Performance Piston Options
Ask the kid on the street what performance is and he’ll raise the hood of his Honda. Ask the Funny Car drag racer about performance and he’ll take you to the starting line to breathe the nitromethane. Ask the mother on vacation and she’ll tell you about driving to California from Indiana pulling a car
What’s Wrong With Our Industry
What’s wrong with the engine building industry today? It’s a simple question that has no simple answer. Like many other – if not every – industry facing difficult times, the factors impacting this market are varied, complex and frustratingly hard to pin down. Are the woes of the industry the fault of customers or suppliers?
Align Yourself
The crankshaft main bores are the foundation of every engine block. The alignment of the main bores is important because their position establishes the centerline of the crankshaft and how the crank aligns with the cylinders, deck surfaces and camshaft. Misalignment in the main bores can cause binding and premature main bearing wear. Misalignment occurs
The Smooth Science of Cylinder Honing
The basics of honing cylinder blocks hasn’t changed much in recent years, but what has changed are the type of abrasives being used by many engine builders. Silicon carbide and aluminum oxide honing stones of various grits have long been used in power honing machines and portable hones to finish cylinder bores. These types
Just Imports
So, you aren’t willing to work on import engines? To you they just seem too complicated and overwhelming? So you end up making the statement that you don’t do foreign vehicle repairs – or more specifically, import engine repairs. What happens when you get an offer to do a Mazda B2300 motor or work on
Dirt Track Dollars In the Shop and On the Track With Malcuit Racing Engines
It’s sometimes said that racers have motor oil or high octane racing fuel in their blood. Fearless drivers are accused of having ice-water running through their veins. For Strasburg, OH’s Brad Malcuit, the most likely ingredient pumping through his bloodstream is dirt, a fact he’ll happily attribute to family heritage. Malcuit is owner of Malcuit’s
