Dialing in on Today’s Engine Bearing Trends
Durability is less of a concern today because the aftermarket and OEMs demand bearings that can last 150,000 miles even under severe stress from a neglectful vehicle owner. In performance applications there are a number of materials that will do the job well. Each material has its advantages in terms of resistance to corrosion, rate
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
Size Matters: Industrial Diesel Engine Builds
When it comes to the various rebuilding markets, almost nothing is as specialized as industrial diesel engines. While many experts say this market is growing at the moment, it can take a supersized commitment to compete in this niche segment because of remanufacturing competition from the OE manufacturers themselves. You’ll need to supersize your tooling
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
Stroker Engine Kits
For more than 50 years the old saying “There’s no substitute for cubic inches” has been the credo of nearly every racer and hot rodder. Whoever created this unwritten universal law could never have imagined to what extremes today’s speed enthusiasts would take it. Now, unless you have a 420cid-plus small-block or a 550cid-plus big-block
Pumped Up For Peformance Oiling Systems
Most OE engines use a wet sump system, which can be modified for performance applications to improve oil control and increase horsepower. A dry sump system, on the other hand, has been specifically designed for performance applications and is mainly used at the higher levels of racing where oil control is critical for producing maximum
Dynamometers and Dyno Operating Systems
The data collected while an engine is running on a dyno can be analyzed to maximize the power gains from various modifications (changes in the fuel mixture, ignition timing, valve timing, compression, the induction system, exhaust system, etc.). Performance engine builders use dynos to measure horsepower and torque so they can optimize engine performance. By
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
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
Over the Peaks and Into the Valleys – Hones, Diamonds and Bores
“Your mission, should you choose to accept it, is to find the recipe for perfect bores…your instructions are to produce bores that are perfectly straight and round. This message will self-destruct after five minutes. Good luck.” Although it’s not “Mission: Impossible,” good bore geometry is critical in order to achieve proper ring sealing. Bore distortion
Old Iron, To Satisfy Vintage Engine Buyers, Go The Extra Mile
Here’s the scene: You’ve just completed the machine work and assembly of a fine vintage engine. It may be for a restoration or a hot rod or a custom. You may have rattle-canned the block and heads and maybe wrapped it up in a baggie. To you, knowing that function is primary, the job is
Aluminum Cleaning & Machining
Steel may still be the big dog when it comes to the content of the world’s motor vehicles, but aluminum usage in cars and trucks continues to increase. Fueled by the desire to save weight, time and energy, aluminum is gaining ground with manufacturers of parts and components. How does the use of aluminum in
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
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
Briggs & Stratton Race Engines
Briggs & Stratton may not sound much like a racing pedigree to anyone not involved in karting, but to those in the know, it’s a name that carries great power and respect. Most engine builders are probably familiar with Briggs & Stratton engines, but not in racing applications – your lawnmower or other garden equipment
Final Wrap: EB Staff Makes Grand SEMA Show Return…Sort Of
Almost lost among the thousands of chrome parts, neon lights, candy apple paints and mega-dollar tradeshow displays was one nondescript little 10×x10× booth tucked away next to a fire department standpipe. No thumping audio system, no gorgeous booth babe, custom car, just three chairs, a small table and copies of the latest issue of our
