Some us definitely get right into every little aspect of the engines workings and performance abilities but then why not it's cheap keeps us doing something we love doing,and its still rewarding to see your improvments or theroy's work out for the betterment of every one.This community like any has it's jokers and theif's ,arrogant fools,and then a bunch of great folks that will share and compare with anyone whom wants to listen and that's invalueable.Bench racing has brought forth many a great idea and talking with like minded people is time well spent in my books LOL.
