What A Year It’s Been…What!? It’s Been A Year?
As I sit here pondering the many topics I could choose to write about for my last column of 2004, I’m suddenly struck by the unbelievable fact that it is December already! Of 2004! Where did 2003 go? What happened to April, for crying out loud? Of course, the holiday shopping days always seem to
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’
Big-Inch Cadillac’s
While some engines are relatively rare in machine shops, the big Cadillacs have remained a consistent source of income. These engines are Cadillac’s last big hurrah at traditional big-cube, flagship GM engines. Surprisingly, they are also a scaled-down version of a V-12 engine that made it through early production and road-testing before being scrapped as
2004 AETC Conference
The 14th annual Advanced Engine Technology Conference (AETC) saw a return to the Antlers Adam’s Mark, in downtown Colorado Springs, CO, Jan. 8-11. The return to this facility, though higher priced than those used in the recent past, was requested by a poll of last year’s attendees because of the higher quality of the hotel
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
Sprint Car Motors
While the World of Outlaws, the All Stars, and USAC are the most well known of the sprint car racing organizations in this country, there are nearly fifty organizations that sanction sprint car racing. In addition, that doesn’t take into account the racetracks throughout the country that have their own division of sprint cars. Although
Lord(s) Of The (Piston) Rings
“He who breaks a thing to find out what it is, has left the path of wisdom.” – Gandalf, Fellowship of the Rings. This is certainly not the case with piston ring technology, although Gandalf from the Lord of The Rings never directed his comments towards engine builders or piston ring manufacturers. Piston ring manufacturers
Pushrods – Key To Performance
Pushrods are the weakest link in the upper valvetrain. Pushrods transfer and redirect the upward motion of the lifters, which goes in one direction, to the rocker arms which move in another direction. Consequently, they are subjected to bending forces as the load and engine speed increases. For stock engines, mild steel stock pushrods are
TIG Welding Opportunities: Working Magic In Cylinder Head Emergencies
Is there a machine in your shop that can be said to work magic? Not only can it fill cracks and repair broken castings, it has the power to create profits, restore power and turn back the hands of time. You might call it a TIG welder, but many of your most desperate customers will
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
Rebuilding The Ford 2.0L
The old 1.9L was modified and upgraded in the process of making it into the 2.0L. The new engine was bored and stroked, it had siamesed cylinders that made the block stronger and quieter, the crank had four more counterweights that made it run smoother, and it had domed pistons for more compression. The
The Honda 1.6L VTEC Engine, Steve Fox
At this year’s AERA EXPO 2003, which will be held at the Las Vegas Convention Center April 23-26 2003, the exciting sport compact performance market and the potential that it has to offer will be highlighted. In that spirit, AERA is building a high performance Honda 1.6L DOHC VTEC engine that will be stroked out
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
A Kubota diesel engine for rebuild
Engine Builders: If you are considering a Kubota diesel engine for rebuild, the following specifications regarding compression pressures will be helpful. For your installer customers, this information will be useful in engine diagnosis. To obtain an accurate value of cranking compression, the engine should be operated until normal operating temperature is reached. If an engine
Rebuilding The Ford 3.8L Engine
They needed an economy engine that would fit in their new cars, and they needed it fast. They had a couple of old inline sixes and a small German V6, but none of them were designed for fuel economy or the coming emissions standards, and the 250 cid engine was so tall that it wouldn’t
Back to Basics: Preventing Piston Problems
Burned pistons. Scuffed pistons. Cracked pistons. These are problems no customer wants to experience in an engine you’ve built. Warranty claims can kill your business, so here are some tips on how to prevent these and other common piston problems. First and foremost, if you’re custom building an engine that has already suffered some kind
