Negative supercharging in the outback??

I gave it a cursory glance, and didn't see that they really said anything meaningful. The generic depiction of a valve timing diagram looked pretty convincing though. :yawinkle:

Efficiency can be increased by elevated temperatures in the fuel charge, but I'd think it would quickly raise oxides of nitrogen enough to negate the gain (in terms of saving the planet and all of that crap). It seems like Smokey Yunick tinkered with this stuff years ago. While he is/was (not sure if he's still around) a good builder, his name isn't exactly associated with playing fairly.

My gut tells me that it's little more than fleecing the masses.
