Tech Notes
Engine Builders: Everyone who works with cars or trucks is familiar with the terms Torque and Horsepower. But do you understand the difference between the two and can you explain it to your customer? It’s important to have a sound understanding of both and the ability to comprehend what defines each measurement of output. By
Fast Lane: New Markets Could Give Your Business Hope For Survival
[email protected] Although some automotive machine shop owners believe that – with engine life measured in six figures – the good days are over, the shops that continuously seek out new markets that parallel their talents and abilities will continue to survive. Those shops willing to invest the time and effort to find those markets will
Engine Builders: Pistons and Rings – Hypereutectic, Valve, Installation
Though pistons can often be salvaged when remanufacturing an engine, sometimes they have to be replaced. The original pistons may have worn or damaged ring grooves, wrist pins or skirts, or they may have cracks. New pistons may also be necessary if the cylinders have too much taper wear and the block has to be
Building Hot Rods & Muscle Car Engines
Sometimes the best opportunities are cleverly hidden in plain view. As one example, when Chris Lafferty of Lafferty Engine Creations was asked why he opted to expand beyond race engines into the hot rod and muscle car arenas, he snorted, “Just look outside.” His North Carolina facility sits squarely in the middle of both NASCAR
AETC Review
The 17th Annual Advanced Engine Technology Conference (AETC) was held for the second year in a row at the Orlando Convention Center, Dec. 11-13, just days before the opening of PRI. While the weather wasn’t frightful, there wasn’t quite as much Florida sunshine as the previous year either, but the talk around each morning’s breakfast
Understanding High Performance Valvetrain Technology
Parts are getting lighter, stronger and capable of producing more horsepower than ever before. One of the driving forces behind these advances has been the proliferation of aftermarket cylinder heads that require unique valvetrain components. In addition, new computer-aided design, modeling and manufacturing techniques are making it easier and faster for valvetrain component suppliers to
Fast Talk: Ward’s Announces ‘Top 10 Best Engines’
The winners of “Ward’s Auto 10 Best Engines” each reflect a changing environment within the automotive industry, according to the publication. Where past lists have been dominated by large-displacement engines, half of this year’s list is made up of 3.0L or smaller displacement engines. Only two of the winners are larger than 3.5L, and four
Performance Notes: EFI Now ‘Doable’ For Every Hot Rodder And Engine Builder
[email protected] It is rare that a new product comes along that redefines a category and a market. Take Apple’s iPod for example. Digital downloading and music file sharing was becoming popular, but a portable device to take your downloaded music with you was needed. Apple’s iPod did just that. Now it’s nearly impossible to go
Engine Parts ETs Drop From Inspiration to Installation
It’s a simple process for those down in the trenches. An engine builder will make a phone call or click on a computer and within days, the latest parts show up at his shop, ready to be installed. But the traditional Stork method of delivery notwithstanding, exactly where do new engine parts actually come from?
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
Coretalk: Jasper Engines Unveils ‘Authentic Custom Drivetrains’ Program
Alex Ernst, Jasper Authentic Group Leader, says the division expects to produce approximately 1,300 engines in 2007. He says the number of drivetrain components that fit the profile of a Jasper Authentic built product will increase as the company begins to establish itself as “one of the premier custom remanufacturers in this market. With traditional
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
Diesel Drag Racing, Compression Ignition Engines Smoke The Strip
It is one of the purest forms of American motorsports. One guy pulls up next to another guy at the starting line and revs the engine. A simple glance over, a nod and a green light. In a fury of sound and smoke, the two racers take off down the straight stretch of pavement. If
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
Wet Flow Testing
Racers and engine builders are familiar with flow testing, used to measure the airflow and efficiency of their cylinder heads. In theory, there are two basic aerodynamic factors that are intuitive in the human mind. Number one, a bigger hole will flow more air. Number two, a smoother hole will flow even more air. To
Engine Sealing: High Performance Head Gaskets
One thing no engine builder wants to worry about is a head gasket failure, whether it is a NASCAR cup engine, a Pro Stock drag racing engine, a dirt track engine, a hot street engine or even a stock engine. Stock head gaskets hold up well enough under normal loads. But as compression ratios and
Machining Solutions For Compacted Graphite Iron
During the last couple of AERA Shows, a seminar on machining a relatively unknown material called Compacted Graphite Iron (CGI) has drawn an interested and growing crowd. The first year’s seminar was the first many had heard about this material and some may have left wondering if this material was headed to their shops any
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
Drag Racing Engines
From the early days of drag racing up until the recent past, racers built everything for their cars themselves, from the engines and chassis to the shop equipment. Most racing teams pulled their racecars to the track behind the family station wagon or pickup truck. The personalities who participated in the sport were as colorful
