5.0 out of 5 stars This is a great book for cylinder head modification, February 17, 1999

By A Customer

This review is from: Practical Gas Flow: Techniques for Low-Budget Performance Tuning (Mrp Speedsport) (Paperback)

This is a really practical method for the modification of cylinder heads. He describes how to make plaster replica castings of cylinder heads and use these castings to develop a high flow cylinder head design. The method uses a simple flow bench that he describes how to make and use. Then using that design, how to transfer your design into the actual cylinder head. In this way, you can make mistakes and go back without ruining your cylinder heads. It is a very scientific but very practical method for making cylinder head modifications that can easily be extrapolated to carburetor, intake manifold, etc. He has a really good section on modifying intake and exhaust valves as well.

5.0 out of 5 stars A must have for DIY cylinder head porting, August 4, 1999

By A Customer

This review is from: Practical Gas Flow: Techniques for Low-Budget Performance Tuning (Mrp Speedsport) (Paperback)

This book shows how to build a flow bench and how to use it. It shows how make a dummy model cylinder head to test the cheanges before starting on the real thing, and what areas to be aware of. Whilst in a specialist area, it is a must have for anyone planning on doing any 4 stroke porting work, which is the key to extracting the best perfromance from an 4 stroke engine

1.0 out of 5 stars Very poor if you're looking for info on building a flowbench, October 30, 2001

By A Customer

This review is from: Practical Gas Flow: Techniques for Low-Budget Performance Tuning (Mrp Speedsport) (Paperback)

It's a fair book on airflow and practical work on porting but I bought it only due to the references on building a flowbench.

The book rates extremely poor on this part and I was very close to returning it. I was looking for serious information to build a flowbench, like good information on test and reference manometer setup for measuring real CFM numbers using orifice plates etc. etc. and there was absolutely nothing in this book in this regards.

Even the flowbench building info that exists in the book is poor, it is only for measuring relative airflow, has nothing on correction factors, calculations, formulas, and is in general very vague and very short on this subject.

Dissapointing. If you're looking for information about building a good flowbench, don't even think about buying this book. A better bet is to get your hands on the PHR and Car Craft articles on the same subject, they are far superior in information for building your own budget flowbench.
