Heavy Duty Diesel Rebuilding Opportunities
It’s certainly no secret that the engine rebuilding industry has been hurt by better quality, longer-lasting automobile engines. The same thing – but taken to an even greater extreme – can be said about the heavy duty diesel engine market. “The quality of today’s engines – both automotive and diesel – is so much better
Building Your Business With Performance Engine Kits
As hard as it is to believe now, the concept of an “engine kit” hasn’t always been well understood. Thirty years ago or so, an engine builder who said he was buying an engine kit probably meant that he was headed to the hobby store to buy the “Visible V-8 Engine” plastic model for his
Restoration – Yesterday’s Treasures, Tomorrow’s Trophies
There have been tremendous and significant changes in vehicle design since the first gasoline-powered vehicle hit the streets of America back in the early 1890s. Such advancements as fuel injection, radial tires, variable valve train technology, roller cams and front-wheel drive, among many others, have made cars easier to maintain, safer to drive and more
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
Common Technologies, Uncommon Fuels, New Challenges
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
The Lives of Lifters, What You Need to Know
It’s like any other mechanical part in an engine. It has a simple yet specifically designed function, it’s not overly complicated and it’s definitely not the proverbial rocket science, tricked-out part. But there’s more to know about the valve lifter than you may think. First off, there are two distinct styles of lifters used in
Coretalk: Recon Automotive Founder Armand J. Mancini Dies
He leaves behind his wife of 42 years, Carole, and three sons and a daughter – Armand, Vincent, Daniel and Carrie Mancini Young. He is also survived by three brothers, a sister and six grandchildren. Mancini was an icon of the automotive remanufacturing industry, having founded Recon in 1973 and building it into one of
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
Coretalk: Female Engine Builders, Hear Them Roar
Clevite Engine Parts has sponsored the Clevite Engine Builder Challenge Series since 1990 and has hosted the event at industry trade shows, conferences, race tracks and open house events for customers – but this was the first build to feature women only. Sandi Holder, of Holder Automotive Machine, and Becky Tardif, of Accurate Cylinderhead Service,
Building Drag Racing Engines and Modification Work
Although drag strips are far outnumbered by oval tracks in the United States – approximately 1,043 oval tracks to just 295 drag strips – the number of competitors in drag racing nearly equals those in the circle track ranks. The NHRA alone has more than 35,000 licensed members. One reason might be that virtually any
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
Gen III GM Small Block Engine, LS1 Motor for Cars, Trucks
The first generation small block was revised to create the second generation LT1/LT4 that was used for some applications from ’92 to ’97, but the results didn’t satisfy the people at GM Powertrain, so they started all over in ’91 and designed a brand new small block. It’s officially called the “Gen III” motor, but
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
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
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
PERA’s Core Corner: Solving The Riddle Of The V10 Chrysler Cylinder Head
In this month’s Core Corner, we ask the question: “When is something you know not what you think you know?” Sounds like a mystery, doesn’t it? For example, when is a car not a car? When it turns into a parking lot! I know, I know – don’t quit my day job. But that really
Fast Lane: Boundless Opportunities Await You in 2005
By now you have all made your New Year’s resolutions, and hopefully, at least one of those goals tions is to look for new opportunities that will help your business become even more successful. This month’s column should give you some help in keeping that resolution. The elections are finally over and the economy is
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
Piston Ring Technology: Stock and Performance
Piston rings have one of the toughest jobs inside an engine. They’re slammed up and down between the ring lands thousands of times a minute; they’re subjected to searing temperatures and extreme pressures; and they’re constantly scraping back and forth against the cylinder walls. In spite of all of this, the rings are expected to
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
