Oil Pumps
It’s 6,000 rpm – do you know what your oil pressure is? That’s a question every engine builder should know the answer to if they’re building an engine that’s going to survive. Maintaining adequate oil pressure and volume is absolutely essential for engine durability. The problem is the output of many stock oil pumps, particularly
DynoMax Names Top Competitors in 2008 ‘Power to the Wheels’ Dyno Tour
After making history last year in the DynoMax Power to the Wheels Dyno Tour inaugural season, enthusiasts everywhere were anxiously waiting to see what – and who – would be competing in this year’s DynoMax Power to the Wheels Championship Shootout. The DynoMax “Power to the Wheels” Dyno Tour tested the horsepower and torque of
Get Ready For The Perfect Storm
Prior to $5 per gallon gas many of us wouldn’t have given the sport compact market a second thought. After 13 years of meteoric growth, the high performance sport compact market stalled, nosed over, and settled into a holding pattern. The Fast & Furious crowd just lost interest. The huge sport compact enthusiast books suffered
Race Engine Pistons and Rings
Cubic inches is the name of the game today. The performance piston market is being driven by bigger bore blocks and stroker crankshafts. A few years ago, a 540 cubic inch motor was a monster motor. Nowadays, some professional drag racers are running engines as large as 850 cubic inches, and 600-plus cubic inch big
Intake Manifolds, Fuel Injected Engines, Carburetors
An intake manifold is more than the plumbing that connects the carburetor or throttle body to the ports in the cylinder head. It is an integral part of the induction system that has to match the airflow characteristics of the cylinder head and camshaft, as well as the displacement and rpm range of the engine.
Drag Racing Cylinder Head Selection
Experts say that the key ingredient is high velocity matched with good flow. But the high flow numbers may blind your customers from seeing the whole picture, so it is up to you to explain. Some cylinder head experts compare flow numbers to horsepower numbers on a dyno – but guess what? They’re not all
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
Coretalk
The California Air Resources Board (CARB) did not vote late last year on a proposal that would have extended emissions warranties to 15 years/150,000 miles on defective emissions-related components. The determination came during a CARB hearing on changes to the Emissions Warranty Information Reporting (EWIR) requirement that would have required car companies that experience more
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 Drag Racing Heads
A quarter-mile strip of asphalt is not a great distance. But drag racing isn’t about distance. It’s about time. The car that reaches the finish line first wins the race. But the car that wins isn’t always the fastest car or the quickest car. It’s usually the car that runs with the most consistent elapsed
Pistons and Pins: What’s New
Asking piston manufacturers “what’s new” reveals a number of trends that are reshaping the piston business today. One is that there’s no longer a time lag of three or four years for aftermarket piston suppliers to tool up for the latest piston applications. Production engine remanufacturers (PERs) and custom engine rebuilders (CERs) are asking for
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
Engine Bearings: Stock & Performance
The importance of the engine’s bearings can’t be over-emphasized. The bearings support the crankshaft and connecting rods, and in pushrod engines also the camshaft. The bearings provide a surface for the friction-reducing oil film that allows the parts to spin without rubbing metal against metal. It’s a tough job because of the high loads created
Performance Marine Engines – Meeting Customer Expectations
Life is a series of compromises. Human relations almost alwaysinvolves compromises of some sort. You want Chinese for dinner,she wants Italian; something has to give. Even if you go yourseparate ways, it’s a compromise and a decision to not dine together. Believe it or not, it’s the same with machinery. Any exercisein design is a
Making A Big Splash In The Marine Market
The average individual that would have owned a performance car in the 1960s, and the baby boomers that did, in many cases no longer have a modern affordable toy they can tweak to their own satisfaction. Serious performance today is often available to only a few with large checking accounts or extra good credit, and
