In the realm of automotive engineering, precision timing is paramount to achieving optimal performance and efficiency. At the heart of this precision lies the camshaft, a critical component responsible for regulating the opening and closing of the engine’s intake and exhaust valves. Traditionally, camshafts have been driven by timing chains or gears, but in recent Read more about Unlocking Performance: The Advantages of Camshaft Belt Drives[…]

In the dynamic world of automotive and marine performance, where every twist of the throttle and every roar of the engine is a testament to power and precision, camshafts stand as the unsung heroes behind the scenes. These meticulously crafted components dictate the rhythm and flow of air and fuel into the cylinders, orchestrating the Read more about Unveiling the Power Within: Exploring the Marketing Magic of Camshaft Branding[…]

In the adrenaline-fueled world of offshore powerboat racing, where every fraction of a second counts and victory hinges on raw power and precision engineering, camshaft design plays a pivotal role in unlocking the full potential of supercharged engines. These high-performance powerplants, purpose-built to dominate the open seas, demand camshafts meticulously crafted to deliver relentless acceleration, Read more about Maximizing Performance: The Art of Camshaft Design for Supercharged Offshore Powerboat Engines[…]

In the realm of automotive engineering, few components are as crucial to engine performance as the camshaft. Whether you’re a seasoned engine builder or a racing enthusiast, understanding the intricacies of camshaft design can mean the difference between victory and defeat on the race course. In this comprehensive guide, we’ll explore the advanced science behind Read more about The Secrets Behind Winning Camshaft Design: A Deep Dive[…]

At Allmond Marine, one of the things we offer that few others do is engineering services to the amateur and professional engine builder. We do this because, at our core, we want to help make engines better. “That’s fair enough,” you might say, “…but why should I hire you?”  Perhaps coincidentally, or maybe otherwise, I Read more about Why talk to an Engineering Consultant about your Engine Development?[…]

Selecting valvesprings is obviously a critical decision point in the development of an engine package. The valvespring is the Witney Carson to the cam profile’s Alfonso Ribeiro – it has to move just as the cam profile directs, but with the disadvantage of being a comparatively low frequency component – that means it tends to Read more about Valvespring Matching – Part 1[…]

Let’s dive into a little “inside baseball”, shall we? There is a misconception amongst engine enthusiasts of what a cam designer does. Certainly part of that job is choosing when the engine wants the intake valve to close, the exhaust valve to open, and when the engine wants both valves open together (the overlap period). Read more about What is Cam Profile Design? Part 1[…]

What is a camshaft “Centerline”? What is a “centerline”? What engine and cam people mean when they say “centerline” is simply, “where does the maximum lift point of the profile occur in the engine cycle?” The term “centerline” is a holdover from the days when the opening and closing flanks of a profile were identical. Read more about Camshaft Centerlines – What They Are and How to Inspect Them[…]

The Question In a recent post seen on a Facebook, the question was posed (link here): “Why does everyone talk about horsepower and rarely about torque, but everyone at the same time screams big cubic inches as this is what moves the boat.” The simple answer is because horsepower is all that matters. Of course, Read more about Power vs. Torque: Which do you Want?[…]

Discussions, even debates, have taken place amongst engine builders on the topic of rocker arm geometry. Some friendships have undoubtedly been strained from the resulting disagreements on the best way to proceed. This series of technical articles will present the problem in a way that I’ve never seen presented in any technical article before. We Read more about Rocker Arm Geometry: An Engineer’s Approach – Part 1[…]
