I am really not all that convinced that it really matters though. I'm not saying the pros don't have special parts or hand matched stuff, they probably do but it doesn't look like that big a difference to me. Sure I've been to big races where I was out-powered but I was running old worn out motors at those. I have also been to big races where I had just as much power as anyone else there. In fact, the first time I went to the Winternats I swear my TQ modded R1WC (with a little extra work by me ) was THE fastest thing there. Well, maybe Swauger and his factory JP could match it but definitely not superior. Four years later I ran that same motor at 301 and people were still coming up to me wanting to know what it was and how I got it to run that well. Broke my heart when the sleeve broke

I guess the real difference is that the pros always have a motor like that while we may get lucky with the occasional missile.
