Howdy All,
The dyno stories of all types are dear to my heart.
A good tester-operator has to be skeptical and tough at the same time if good data is the goal.
I have written a book on Dyno Testing and Tuning with co-author Bill Hancock. It is available from any number of sources including the publisher
www.cartechbooks.com. This is the first time all this kind of information has been between two covers. The book covers test procedures and various corrections and other details that are targeted for gearheads. The book is written in a generic fashion so that it can apply to all types of test equipment (dynos), both chassis and engine types.
This is not intended to be a crass commercial, but wanted to call your attention(s) to its availability. You can go to Barnes and Noble and see if they have any on the shelf. IF they do, you can sit down and read/scan through it and decide if it is of interest to you.
The comments about 100 rpm/sec are spot on. Takes some stones to get used to laying the throttle down and letting her eat for a while, but that is the way to get some really good data. A great time to smack a steel plate with a hammer if anybody has a sense of humor, but it gets pretty dicey doing that!
Now I am writing another one about airflow through engines and flow benches, too. Should be out toward the end of the year (I hope).
Regards to All,
