Sorry, they may BS about it but you are still not getting that big of displacement. You may get more power by firing so many times per revolution but you are not getting a bigger displacement. Also, how do you get good gas miliage if you are firing 32 times per rev? Sounds like BS to me, but then again what do I know, huh?
Math doesn't lie. The displacement is what it is.
MPG? Now that remains to be seen.
