Single pane vs Dual pane

Desktop Dyno is not much better then a car on Xbox. Real world is what you need to concern yourself with. Your engine may have issues holding it back. I love seeing engines that were "dyno'd" by the desktop on a real dyno. Guess which one is ALWAYS much higher? I've seen several "500hp 440s" that cant pull 450 at the crank. Never focus on the numbers, only the trends, and you'll be much better off.
