These are great books for technically inclined folks. In fact if you are an engine nerd with a Banshee, they are a must read. Bell has several other books whose hard copies come in and out of print sporatically (the two stroke book is out of print) that are also excellent.
Potentially, these books may have alot of stuff that is over the general memberships current knowledge level, but if you post up your questions, several of us will be glad to try and snwer them! :geek:
