Come to Nitro School on Saturday at any national event and you will learn things like this. In Atlanta, Tim Wilkerson is my c0-professor and in Topeka, it will be Jim-O, I promise, whether you are a new fan or a veteran you will learn something.
And the Horsepower curve on a nitro car is just that, a curve, the engines are in constant adjustment, fuel, timing. clutch load, etc....
