Use more control, let your prop pitch slowly work its way down to 9:30-9:45, keeping it in the powerband, and you'll see a lot more speed. Plus, its way easier to keep the engine under control in dives, if you start at the low end of the powerband instead of the high end. Get the revs back up when climbing.

I find I do most of my dogfighting at around 10:15, and slowly works its way up as I lose energy and need more and more bite from the engine. When you're still dogfighting and your PP is already at 12:00, you know you've done it wrong and you're running out of time.
I'll give that a shot.
It would really nice if someone can explain what's the relationship between RPM, power and speed? Is there a formula that links them together? Intuitively it doesn't make any sense to me. It's probably better to look at a math formula. I actually took a intro to Aerospace Engineering class in my freshman year in college, but we didn't cover anything propeller related. all we talked about was the airfoil.
