Dyno-Proven GM LS1 Thru LS7 Performance Parts by Richard Holdener (2007, Paperback)

I bought this book and actually had to wait for it due to the long back order log. I even attempted to purchase it in more than one place, but all were back ordered. I wanted this book after purchasing my LS1 powerered Tran Am in an effort to find what modifications would actually work, and where I could put money to gain the most bang for the buck.
This book was very descriptive in every one of their dyno results, and covered a wide selection of modifications. In fact it covered every possible power adder availible today. It will give the author's opinions on different modifications and will tell you which really don't even work. They break down many myths that you read on the internet as well.
This is no how-to book. They do not explain or detail any kind of installations. They cover in great detail the results, but no instruction. There is also no actual real world performance tests. In other words, no track or strip tests. Strictly dyno tests, just as the title emplies.
If you are planning to dive into any LSX series engine for perfomane gain, and are wondering what a certain modification will give you to the rear wheels, then this book is it. If you are looking for a how-to performance manual, this is not the one. Overall, for what it covers, it is a great book and worth the time and money. Find another how-to book and together built yourself a killer LSX car.
