Extracting maximum torque and horsepower from engines is an art as well as a science. David Vizard is an engineer and more aptly an engine building artist who guides the reader through all the aspects of power production and high-performance engine building. His proven high-performance engine building methods and techniques are revealed in this all-new edition of How to Build Horsepower.

Vizard goes into extreme depth and detail for drawing maximum performance from any automotive engine. The production of power is covered from the most logical point from the air entering the engine all the way to spent gasses leaving through the exhaust.
Explained is how to optimize all the components in between, such as selecting heads for maximum flow or port heads for superior power output, ideal valvetrain components, realizing the ideal rocker arm ratios for a particular application, secrets for selecting the best cam, and giving unique insight into all facets of cam performance.
In addition, he covers how to select and setup superchargers, nitrous oxide, ignition and other vital aspects of high-performance engine building.

Vizard's "How to Build Horsepower" explains the latest and most effective engine building techniques and strategies. The reader is treated to the secrets and methods for building virtually any automotive engine. Vizard's unique and entertaining style of writing clearly explains the key principles and provides extreme detail and uncommon insight.

The needs of a true competition engine are quite different than those of the engine under the hood of a typical commuter car. From the basic design needs, to the base component materials, to the sizes of the flow-related hardware, to the precision of the machining, to the capabilities of each pertinent system, very few similarities exist.

Many books exist showcasing how to make street-based engines more powerful and/or durable.

This book is different, in that it focuses purely on the needs of high rpm, high durability, high-powered racing engines. It begins by looking at the raw design needs, and then shares how these needs are met at the various phases of an engine's development, assembly, testing and tuning.

This book features reviews of many popular modern tools, techniques, products, and testing/data collecting machinery. Showing the proper way to use such tools, how to accurately collect data, and how to use the data effectively when designing an engine, is critical information not readily available elsewhere.
The special needs of a competition engine aren't commonly discussed, and the many secrets competition engine builders hold closely are openly shared on the pages here.

Authored by veteran author John Baechtel, Competition Engine Building stands alone as a premier guide for enthusiasts and students of the racing engine. It also serves as a reference guide for experienced professionals anxious to learn the latest techniques or see how the newest tools are used.
Baechtel is more than just an author, as he holds (or has held) several World Records at Bonneville. Additionally, his engines have won countless races in many disciplines, including road racing and drag racing.

Engines are built to fall within a wide set of standards and specifications, often not optimized to meet the original design. In short, cheap and fast engine production results in a sloppy final product. Of course, this is not idea for high-performance engines.

To maximize the performance of any engine, it must be balanced and blueprinted to the exact tolerances that the factory should have adhered to in the first place. Four cylinder, V-8, American or import, the performance of all engines is greatly improved by balancing and blueprinting. Dedicated enthusiasts and professional racers balance and blueprint their engines because the engines will produce more horsepower and torque, more efficiently use fuel, run cooler and last longer.

In this book, expert engine builder and veteran author Mike Mavrigian explains and illustrates the most discriminating engine building techniques, so the engine is perfectly balanced, matched, and optimized. Balancing and blueprinting is a time consuming and exacting process, but the investment in time pays off with superior performance.

Through the process, you carefully measure, adjust, machine and fit each part together with precision tolerances, optimizing the design and maximizing performance. The book covers the block, crankshaft, connecting rods, pistons, cylinder heads, intake manifolds, camshaft, measuring tools and final assembly techniques. It provides an unprecedented level of detail and instruction on the process of balancing and blueprinting your engine.

Drawing on more than 30 years of experience in engine research and development, backed up with a computer-age workshop, David Vizard gives a comprehensive guide to tuning the A-series engine for either performance or economy. He provides the very latest technical data in the third edition of this best-seller, which has nearly 750 illustrations and an easy-to-follow text.

Provides the working knowledge for keeping a V-8 at the top of its form. And for those who'd like to understand how the engine works, the book also includes lucid explanations, beginning with the theory of cylinder head flow.
In clear, easy-to-follow terms, custom V-8 builder Scott Parkhurst offers detailed information and expert advice about block preparation, choosing a reciprocating assembly, and selecting a cam to compliment the heads and meet your own driving needs and performance goals. He also addresses ancillary components such as carburetion, fuel injection and header selection.

Back in print and completely updated to cover more recent engines and taking into account new emission control laws, etc.
For the do-it-yourself tuner intent on increasing the power output of a car engine, no problem is greater than how to measure, assess and understand the flow of gases through the inlet tract, clylinder head and exhaust.

Gas flow, complex, variable and invisible, is the key to an engine's performance, and professionals use very costly equipment for its investigation.

This book describes a practical low-cost alternative that lets you check the gas flow in your engine, devise improvements and test and compare their effect: it needs patience, persistence and some manual skills, but no great financial outlay.

Porting heads is an art and science. It takes a craftsman's touch to shape the surfaces of the head for the optimal flow characteristics and the best performance.
Porting demands the right tools, skills, and application of knowledge. Few other engine builders have the same level of knowledge and skill porting engine heads as David Vizard.

All the aspects of porting stock as well as aftermarket heads in aluminum and cast-iron constructions are covered. Vizard goes into great depth and detail on porting aftermarket heads.

Starting with the basic techniques up to more advanced techniques, you are shown how to port iron and aluminum heads as well as benefits of hand and CNC porting.
You are also shown how to build a high-quality flow bench at home so you can test your work and obtain professional results. Vizard shows how to optimize flow paths through the heads, past the valves, and into the combustion chamber.

The book covers blending the bowls, a basic porting procedure, and also covers pocket porting, porting the intake runners, and many advanced procedures. These advanced procedures include unshrouding valves, porting a shortside turn from the floor of the port down toward the valve seat, and developing the ideal port area and angle. All of these changes combine to produce optimal flow velocity through the engine for maximum power.

Wenn es um Leistungssteigerung bei Viertakttriebwerken geht, richtet sich der Blick zuerst auf den bzw. die Zylinderköpfe. Hier wird das von Vergaser oder Einspritzung gelieferte Gemisch in pure Pferdestärken umgesetzt.
Im Verständnis um die Funktionszusammenhänge der einzelnen Bauelemente des Zylinderkopfs liegt der Schlüssel für hohe Leistung, Zuverlässigkeit und Wirtschaftlichkeit eines jeden Viertaktmotors, sowohl im Straßenbetrieb wie für den Einsatz im Motorsport.

Dieser Band der Praxishandbuch-Reihe beschreibt in aller Ausführlichkeit und mit Hilfe zahlreicher Bilder und Illustrationen zunächst die theoretischen Grundlagen der Zylinderkopftechnik und erläutert dann mögliche Schritte zur Leistungssteigerung. Hierbei werden sämtliche Baugruppen gesondert betrachtet - vom Einlass bzw. der Gemischbildung, über Zündung bis hin zum Auslass bzw. der Auspuffanlage.
Leicht verständlich geschrieben und sorgfältig zusammengestellt bietet dieses Buch dem technisch interessierten Leser alles, was er wissen muss, um mit Erfolg Arbeiten am Zylinderkopf durchführen zu können.

Explains in simple language how to choose the right camshaft(s) for your application, and how to find the camshaft timing which gives maximum performance. Also explained are all aspects of camshaft design and the importance of lobe phasing, duration & lift.

Applies to all 4-stroke car-type engines with 4, 5, 6 or 8 cylinders. Avoids wasting money on modifications that don't work. Applies to road and track applications.

Wie scharf darf es denn sein? Wer einen Motor präpariert - sei es, um ihn ernsthaft zu frisieren, sei es, um einfach das Beste aus der Serienmaschine herauszuholen -, kommt ums Thema Ventilsteuerung nicht herum. Dreh- und Angelpunkt ist im Viertaktmotor die Nockenwelle. Die gibt es von mild bis scharf, von nagelneu bis aufgearbeitet.

Des Hammill, Ingenieur und erfahrener Profi-Rennmotorenbauer, weiß, worauf es ankommt. In diesem Praxishandbuch der Edition Oldtimer Markt verrät er, wie man die richtige Welle findet, wie man die Steuerung richtig einstellt und wie man sie testet.
Sollte Ihr Motor nach dem Tuning trotz Beherzigung der Tipps aus diesem Buch noch immer nicht laufen - an der Nockenwelle liegt es dann bestimmt nicht.
