Performance Valves
The power that an engine produces depends to a large extent on how much air it flows. The larger the engine’s displacement in cubic inches, the more air it pumps with every stroke and the more horsepower it makes. Rpms also make power. In theory, doubling the engine’s speed doubles its power output. Rev an
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
Fast Lane: Boosting Your Business With A Web Presence – Part II
In part one of this series (“A Web Site Can Add To Your Business Bottom Line,” August 2006 Engine Builder, page 38) we talked about the need for every business to have a Web site, regardless of what type of business you are in. Sadly, in the recent Machine Shop Market Profile in this very
Salaries & Benefits
The subject of money tends to be one of the most sensitive topics in our society. In most situations, it’s the most impolite question ever. Most decent Americans are embarrassed to ask it. And yet, like rubbernecking at an accident on the highway, we’re drawn to know: How much do you make? At trade shows,
High Performance Rocker Arms, Valve Springs, Retainers and Locks
On a small block Chevy, altering the rocker arm geometry without changing the rocker arm lift ratio can add 15 to 20 horsepower at the rear wheels. The stock lift ratio for a small block (SB) Chevy V8 rocker arm is 1.5:1, and for a big block (BB) Chevy V8, the ratio is 1.7:1. Bolt-on
Performance Notes: Stud Vs. Shaft Rockers: Why You Should Make the Switch
When the Chevrolet small-block V8 was introduced in 1955, one of its most highly touted features was its lightweight, high-revving ball and stud stamped steel rocker design. Around 1962, several of my buddies proved that claim to be true, time and again, when they twisted their Duntov-cammed 283s to 7,200 rpm. In fact, this same
Fast Lane: A Web Site Can Add To Your Business Bottom Line
Hopefully everyone out there is familiar with the Internet. While there are some things about the Internet that most of us would rather not deal with, the value it has provided far outweighs any bad. A Web site is also the most cost-effective advertising you can do. As a journalist, the Internet is the first
Vizard’s View: Avoiding Flat Tappet Cam And Lifter Failure
There is nothing worse than building a cost effective engine for a customer, shipping it, and then having it come back a short while later with the installed flat tappet cam wiped out. Even if the cam and valve train was warranted by the cam manufacture, you, as the engine builder, will bear the brunt
Coretalk: National Crankshaft Co. Becomes Newest EPWI Branch Warehouse
NCC joins other EPWI warehouses located in Denver, Phoenix, Albuquerque, Dallas, Oakland, Oklahoma City, Houston, San Antonio, Portland (OR), Tacoma and Anchorage. “EPWI is making enhancements to the programs and product lines currently offered, as well as adding many new product lines” according to Paul Van Woensel, president of EPWI. “NCC’s customer support programs are
Timing Chain Selection: And a look at ‘new’ and ‘how to’
The simple timing chain: it has a distinct function, yet constantly changing designs, materials, procedures and refinements make for a part that seems to evolve by the month. With such changes going on, how do we know what chain and gears are the best to use on a particular engine? When the automobile was invented,
Advances in Cleaning Equipment
You could argue that the dishwasher is one of the greatest inventions of the twentieth century. Up until its introduction in households, people had to wash each dish individually, by hand, and dishpan hands were common among women and children. But the dishwasher changed all of that for families, and on its arrival, children everywhere
Pushrods & Lifters
Pushrod engines have been dubbed as antiquated technology by some, but for many engine builders these engines are far from suffering the fate of the horse and buggy. In fact, with both GM and Chrysler keeping the pushrod engine alive in their current product lineups with the Gen IV, Hemi and others, pushrods and lifters
Tuning in to the Sport Compact Market
While the American muscle car segment is getting a shot in the arm with the Mustang, Charger, GTO and others, the sport compact market is not going away any time soon. Much has been said about the possible demise of this once fast-growing market but according to some manufacturers there is still plenty of business
Performance Cam Revolution – Valvetrain Advances Give More Power to the People
When selecting a performance camshaft, everything in the engine must be considered because change one thing and something else is affected. One cam supplier said that advances seem to happen daily, so it is important to stay abreast of the latest trends. The basic function of the camshaft is to open and close the valves
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
Aqueous Cleaning Systems Offer Economical, Ecological Benefits
As concern for the environment and worker safety has increased over the years, attention paid to the cleaning processes used in engine rebuilding facilities has sharpened as well. No matter what size the shop, engine components are dirty and need to be cleaned. There are numerous ways to clean parts, of course, and no method
Rebuilding the Ford 3.0L
This engine came out of the Cleveland Engine Plant #2 (CEP2), originally opened in 1955 to manufacture the 361 cid truck engine. By 1985, this facility was down to 400 employees and on the verge of closing. Then in 1988, plant renovation was begun (with the 3.0L Duratec engine family on the drawing board) at
Valve Guide and Seat Equipment Options
For many engine builders the bread and butter business is in cylinder head work. In fact, according to our 2005 Machine Shop Market Profile (also available at www.engine-builder.com) 41 percent of gas and 54 percent of diesel engine builders’ business comes from servicing cylinder heads. And one of the most important aspects of doing this
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
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
