My question is simple. Why does the Raptor in stock form only slightly if at all out perform a 450. I am mainly talking in a drag race. Why are they so close in comparison in speed and horsepower? I get asked these questions all the time. My friends have 450s and a 525 and when I beat them in a drag they always say well its not by much and that I should kill them since I have such a bigger engine. Can anyone answer this?
