Yeah, depending on load, the timing may spark the plug a lot further before TDC than you'd think, the fuel detonation does take a finite amount of time, long enough for the piston to be in the optimal position when the pressure can most effectively be used.
That said, everything else about fuel vapor is pure BS. If someone is stupid enough to believe it, they aren't going to be smart enough to understand actual science, no point trying to make sense to them, as we've seen before it falls on deaf ears..lalalalala I can't hear you......but you must listen to yet another pointless, baseless, pseudoscience, sounds good to me so it must be true "Fact".
I say we encourage racprops.....lets all go dredge up like minded crap about the vapor thing and get him to build something really extreme dealing with fuel heated to hundreds of degrees and pressurized thousands of pounds outside the combustion chamber, like maybe in a Soda bottle (wrapped in multiple layers of duct tape of course). Then we'll maybe see if Darwin had the right idea.
