So it wouldn't benefit from Multiport Fuel Injection and Variable Valve Timing? Maybe I am just confusing engine efficiencies and combustion efficiencies - but it seems to me a carbed engine cannot be 99% efficient in burning up the gas into useable power - and certainly not 100% of the time (i.e. cold starts). A carb creates a relatively low pressure mist which then travels through an intake manifold to the combustion chamber. Isn't that the whole rationale for EFI and VVTI - to put the gas in a good state for combustion and combust it at the perfect time? I have a hard time imagining the gas is in a perfect state to be combusted at that point. Moreover, step on the gas and the carb dumps excess fuel into the combustion chambers. I don't know how much more gas pours in at that time (2x, 5x?) but there is certainly no corresponding instantaneous increase in power from that gas that was dumped in there. Now maybe this is just semantics and we're really talking about engine losses, but I don't see how you get 99% efficiency out of that. Again, I'm not saying 99.9% of the gas doesn't burn. I am just saying I don't think it burns at the right rate or time to get 99.9% of the USEABLE energy from it.

Physics and Calculus was 20 years ago for me - that just gave me a headache. And as you appear to be well versed in things mechanical, most equations consider the ideal situation. Reality is never ideal.

Again, I'm not endorsing the product - just saying it hasn't been proven NOT to work yet. Maybe people can show, without bias, that it does work. I can assure you, I am just as skeptical as you are. But I also know I don't know near enough about the process and physics to dismiss the idea off the bat. (although, some of the claims made have been straight up BS - and those CAN be dismissed right off the bat)
