There is nothing more fun than to show up at the flying field with a stock looking engine and watching heads turn when your engine is not what it appears to be. There is also much gratification in scaring the "woohaas" out of the guys that have had their wallets emptied by buying a thoroughbred racing engine instead of making it. You may not stay on top with your "labor of love" racing engine but you will send the "big boys" into a tizzy thinking that they have to go spend some more money! The Nelsons and Jetts are hard to beat..no doubt about it...but they can be beat. And when you do beat one, it infurriates them. Now that there's funny!!! Being on top is great but sooner or later, no matter how much money you have spent, you will get dethroned. I prefer the cheap and sneaky approach plus you get a better education on what makes an engine tick. We learn from our mistakes. That is why I'm getting smarter every day! Let's go flying!
