‘Heads Up’ On Today’s Cylinder Heads & Bolts
Some say the air cleaner of an engine is like the front door of a house. That is, it’s what you see first and foremost. And the home owner can use that door to make a statement about the house without anyone seeing what’s inside. Much like what an air cleaner says about an engine
Valvetrain
Selecting the right components to make a rock-solid valvetrain is key to assembling an engine that will last – and win. The pushrods, rockers and valve springs must be able to handle all of the stresses of the camshaft rotating with high spring pressures and with huge lift. Weakness in any part of the system
Going Green Not Just for Irish
Did you know that as engine builders, we were green long before green became the IN thing? We were green even before Kermit said it wasn’t easy. How are we green, you ask? We are green because we rebuild, which means we recycle. Green is defined as: • Relating to or being an environmentalist
Green Strategies: Cleaning Techniques & Equipment
It may seem that there’s nothing natural about cleaning an engine. Even after the couple of hours of cleaning time, the engine might be cleaner than the tech working on it – but the engine still needs cleaned (and so does the cleaning crew from time to time). We are long from the days of
Green Strategies: Recycling Scrap and Precious Metals
Engine rebuilding, arguably the truest form of recycling, restores core durability and is part of the 3 Rs: Reduce, Reuse and Recycle. In fact, the very definition of the word “recycle” could be interchanged with “engine rebuilding.” Recycling means to reuse or make (a substance) available for reuse for biological activities through natural processes of
Engine Builder Shop Solutions: March 2013
Safe Valve Spring Break-In Most engine builders are well aware of the fact that high performance valve springs should be compressed to coil bind through several cycles before being installed. The problem with this procedure is that it can be time consuming, costly and even dangerous. It is time consuming if each spring is compressed
Bearing Clearances
Is it better to build an engine with tighter bearing clearances and run it on low viscosity synthetic motor oil, or is it better to build an engine with more traditional or even looser bearing clearances and use heavier viscosity oil? Tight bearing clearances and relatively thin synthetic multi-viscosity motor oils work well in many
Rebuilding Chrysler’s ‘Revived’ Engine Family
Casting numbers, VIN codes, components and processes to rebuild/remanufacture these engines are compiled for Chrysler’s newly revised engine family including 4 cylinders, V6s and V8s Chrysler made some major changes in their engine line-up starting in ’07. They replaced their four cylinder engines in everything but the PT Cruiser in ’07, updated the 4.7L V8
The Raptor Takes Flight
In an age when kids would rather hot rod their computers than their cars, it’s kind of amazing that old fashioned hot rodding still exists – even thrives in today’s society. While computers certainly have their place, the younger generation is still looking for entertainment and thrills – whether captured in HD?or in real life.
World’s Smallest V8 Engine
Gary Conley’s 30-year quest to manufacture a true production V8 engine in quarter-scale almost went up in smoke twice, once in 2001 when a foundry fire claimed all his critical molds, and later when oil smoke proved a stubborn problem during run-offs of the engine. Conley overcame the first setback with years of sheer determination.
Matching Pistons And Rings
Whether you are rebuilding a high-mileage engine or building a fresh engine from scratch, matching the pistons and rings to each other and the application is essential for a successful outcome. Rings are a wear component that are usually replaced during a rebuild. The pistons may be reused if they are not damaged, cracked or
What’s on the Dyno?
Brad Lagman and his crew at Chatsworth, CA-based QMP Racing Engines (qmpracing.com) get to build engines for some pretty cool toys all day long, but this one may be one of the more unique builds they have ever done. The engine will be dropped in a buggy that runs on sand and kicks giant roostertails
Fidanza Engineering Gets New Ownership, New Name
Now doing business as Fidanza Performance, the company will be lead by ten year company veteran, current president and now owner, Jeff Jenkins. “Lou has been producing great products under the Fidanza name for nearly 20 years and has grown Fidanza to a world recognized brand.” says Fidanza Performance’s new owner/president, Jeff Jenkins. "And we
Today
Although extremely important, the job of cleaning engine parts leaves nothing to the imagination. You’re idly standing with a spray gun in your hand or beside a washer tank or cabinet. It’s a basic, time-consuming procedure, but that grime, oil and baked-on sludge won’t come off by itself. This necessary evil is the difference
Heavy-Duty Coolant Options
While the fundamental duty of engine coolants has not changed – they must transfer excess heat and offer freeze and boiling protection, plus corrosion and liner protection – modern coolants must transfer more heat than in the past, largely due to new emissions systems. When considering the energy consumed to power a heavy-duty diesel
HPBG: Choosing Aftermarket Cylinder Heads
If the performance business is about one thing – it’s about improving upon what comes in the door and making it better for your customer’s application, whether he’s racing down the quarter mile, hitting the twists and turns of a natural road course, or just driving it to the movie theater with his girl by
Racing Rocker Arm Technology
The rocker arms play a more important role than ever these days in high performance valvetrains. The rockers are the teeter-totters that translate the upward motion of the lifters and pushrods to the downward motion that opens the valves. It seems like a relatively simple task, but it demands the utmost from the design of
Automotive-Powered Inboard Hydroplanes
They’re fast, have power aplenty, can turn on a dime, and throw a huge column of water behind them. They’re called Inboard Hydroplanes and are one of the most exciting motorsports shows on water with their automotive powerplants. The Inboard Hydroplane The looks of these boats spell speed with fighter aircraft aerodynamics on both the
Crank It Up
Whether you think diesel crankshafts are the same as or different from their smaller gasoline counterparts, you’re right. Diesel crankshafts and rotating assemblies – like their cousins in the gas engine world – turn a linear motion from combustion into a rotating motion that can move a vehicle, supply power through a generator, pump oil
Nitrous
A nitrous engine can be built as a stock rebuild or it can be a dedicated effort to maximize the total performance package. As more power is generated, more waste heat, exhaust air flow and combustion pressures push the limits of engine strength. Often more beef is needed in the drive train and tires. The
