Testimonials & Reviews for Back Pocket Dyno

Retired Master Engine Builder for Gale Banks Engineering – Ron Fleetham – (Lake Elsinore, CA)

“The Back Pocket Dyno is a big blessing in a small package. I have used this guide for years and even taught classes building courses from it. It is my professional opinion that every engine builder and every car builder should have one in his or her own back pocket.”

Custom Car Builder (BOSS 5.40) - Tim Albers - (Alberta, Canada)

“That little book is a must for me and should be for every hotrodder!! You can see one of my cars that was at SEMA in 2009. Do a Google search on “Boss 5.40″ and you should get lots on it. It is a blue 1970 restomod with 2008 Shelby motor with about 750 RWH. I did use the book too.”

Pro-Mod Owner/Builder/Driver - Ron Kammes – (Chicago, IL)

“The Back Pocket Dyno gives you everything needed to make the right decisions the first time. I have personally recommended and sold many copies of this handy little guide. The book is small but packed full of wisdom and insight. I have personally used this guide repeatedly throughout my racing career and feel it is worth many times the asking price. Put one in your back pocket before you build your next race car…… see you at the track!”
