How to Choose Camshafts & Time them for Maximum Power (Veloce SpeedPro)

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.

David Vizard's How to Port & Flow Test Cylinder Heads

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.

Practical Gas Flow - Techniques for low budget performance tuning

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.

Dyno Testing and Tuning

The first book to explain the proper testing procedures that everyone should use to get accurate and useful results from either an engine or chassis dyno. Authors Harold Bettes and Bill Hancock, recognized experts in the performance and racing industry, apply their wealth of knowledge and experience to deliver the definitive work on dynamometers and dyno testing.

This book will be useful to anyone who wants to squeeze more power out of their car or engine, but should also be required reading for performance shop owners and dyno operators.

The book explains how a dyno works, describes what kinds of data a dyno test can produce, and then shows you how to plan a test session that will give you the results you're looking for.
You'll learn what to look for in a dyno facility, how to conduct a dyno test and ensure the accuracy and repeatability of your test, and how to troubleshoot any problems that arise. Sample forms and checklists round out what is sure to be an indispensable book for anyone who wants to make the most of their dyno testing.

Praxishandbuch Zylinderköpfe

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.

Praxishandbuch Nockenwellen - Verstehen, Pflegen, Optimieren

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.
