We recently learned of the sudden passing of Rob Deneweth, Ford Racing’s Powertrain Engineering Supervisor. Having worked with Rob on a number of occasions, we came to appreciate his knowledge, and always enjoyed his company. Most recently, Rob was spearheading the development of the 2014 Twin Turbo Cobra Jet engine that we talked about in our SEMA coverage last month. Here is a statement released by Jamie Allison, director of Ford Racing:

“All of us at Ford Racing are deeply saddened by the passing of our colleague and friend Rob Deneweth. Those of us at Ford involved in the racing program are very much like a small family, and when you lose a member of your family, you grieve and feel a real loss. Rob was a terrific engineer who did such great work, including his effort with the most recent Twin Turbo Cobra Jet project. All of us at Ford Racing send our deepest condolences to Rob’s wife, Julie, and their three children. We have lost a true friend.”


Book review: How to Port and Flow Test Cylinder Heads

Porting heads is both an art and a science. It takes a skilled craftsman to shape the surfaces of the head for the optimal flow characteristics and the best performance, and it demands the right tools and application of knowledge. Author David Vizard covers all aspects of porting stock, as well as aftermarket, heads in aluminum and cast-iron. Vizard goes into great depth and detail on porting aftermarket heads. In this book, Vizard also shows you how to build a high-quality flow bench at home, so you can test your work and obtain better results.

Vizard shows how to optimize flow paths through the heads, past the valves, and into the combustion chamber. The book also covers blending the bowls (a basic porting procedure), and also covers pocket porting, porting the intake runners, and many advanced procedures such as unshrouding valves, porting a short side turn of the port down toward the valve seat, and developing the ideal port area and angle.

Over a 50-plus-year career, Vizard has built race-winning engines and cars, and has penned nearly 4,000 magazine articles and 30 books. Vizard is also the owner and operator of MotorTec Magazine in Charlotte, North Carolina.
