Sprint & Midget Racing Engine Market
While the World of Outlaws, the All-Stars and USAC are the most well-known of the sprint car racing organizations in this country, and USAC is probably the best known of the midget racing organizations, there have been many new groups surfacing in the past several years. According to Allan Brown, publisher of The National Sprint
Understanding Valve Design and Alloys
To the naked eye, a valve is a valve is a valve. Sure, there may be two, three, four or more of them in the cylinder head, but unless you have x-ray eyes, one alloy looks pretty much the same as another. The importance of coatings to today’s valves should not be overlooked, of course.
Oil Pumps
It’s 6,000 rpm – do you know what your oil pressure is? That’s a question every engine builder should know the answer to if they’re building an engine that’s going to survive. Maintaining adequate oil pressure and volume is absolutely essential for engine durability. The problem is the output of many stock oil pumps, particularly
Connecting Rods: So Many Choices
Choosing a set of connecting rods for a performance engine is not as simple as it sounds. The rods you ultimately choose to use in an engine will depend on a number of factors, each of which can be critical to the life of the motor and the success of your customer. Your decision will
Mid-Range Diesels: Going the Distance
While it may seem that we’re constantly asking you, the reader, to give us detailed information about your business, the truth is, details are what make this business interesting. In that respect, following the February issue of Engine Builder, a cross-section of readers were asked for their opinions on a number of topics, ranging from
Race Engine Pistons and Rings
Cubic inches is the name of the game today. The performance piston market is being driven by bigger bore blocks and stroker crankshafts. A few years ago, a 540 cubic inch motor was a monster motor. Nowadays, some professional drag racers are running engines as large as 850 cubic inches, and 600-plus cubic inch big
Today’s Oil Not the Same
A recent camshaft company Technical Bulletin said it best: “Today’s engine oil is just not the same as it used to be, thanks to the ever tightening environmental regulations.” The EPA, car manufacturers, and the American Petroleum Institute (API) have done a great job reducing emissions and extending the life of emissions control equipment. However,
Stroker Tips from the Pros
Engine Builder’s Stroker Motor Resource Guide has become an annual feature. Last year this publication ran an introductory story about increasing your business with the growing demand for stroker engines. It was focused on popular O.E. and aftermarket-based engine combinations, and covered the basic dos and don’ts of building a stroker motor. We are fully

Diesel Pistons
The diesel engine market has been rapidly changing in recent years. Higher fuel prices and changes in emission regulations have brought about a whole new generation of clean diesel engines in both the light and heavy-duty truck markets. According to the Diesel Technology Forum (www.dieselforum.org), particulate emissions from new on-highway diesel engines have been reduced
Off Road Racing Engine Market
It had been a long week in Las Vegas, manning the booth and getting the scoop on the performance market at the SEMA Show. I was tired and ready to catch a plane back home, but I had one last assignment before I left: Go into the desert and cover an off-road race. I woke
Rocker Arm- Form & Function
For all the changes in the performance engine over the years, one constant remains – no matter what series they’re running, no matter what the payout, no matter if it’s just a couple of guys trying to outdo each other stoplight to stoplight, racers will often spend money they don’t have in search of the
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
Performance Notes: Cashing In On Power Adders: Blowers, Turbos, Nitrous
The demand for high performance vehicles has never been stronger. A good indicator is that automakers are turning out more powerful models with each successive new car introduction. Remember when 500 horsepower was a pretty good number for a race motor? Today you can purchase a number of vehicles that eclipse 500hp, from a Z06
Marine Engine Building, Is It For You?
Engine builders who do passenger car and light truck engines, diesel engines and performance engines, are often looking for new market niches where they can expand their business and add new customers. For some, marine engine building may seem like a tempting niche. The marine engine market is relatively healthy, though highly competitive. Some rebuilders
Data Acquisition Systems and Engine Controllers
Motorsports in general and Formula One in particular is the leading edge (or bleeding edge, depending on how you look at it) of development of these electronic systems. With carburetors looking more and more like dinosaurs compared to modern electronically controlled engine management systems, engine builders – especially those building performance engines – must become
Engine Parts Coatings
Lubricity, heat management, corrosion protection and cosmetics. These are the main benefits that coatings can provide when applied to the surface of various engine parts. But there are different coating materials for different purposes, so the key to maximizing engine durability and performance with coated parts is using the right coating materials in the right
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
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
Has Hot Honing Cooled Off?
No matter how perfectly straight and round it may be when it is machined, a cylinder bore will change shape when cylinder heads are installed and when the engine reaches normal operating temperatures. During a presentation at the 2002 PRI Show, the subject of “Hot Honing” caused a tremendous stir of excitement among performance engine
