The whole thing can be debunked very quickly. Its based on
A) a cam that creates a "low pressure" senario. Basically, thats how an NORMAL NA engine works anyhow, they are just messing with overlap...no big deal there.
B) That hot gasses explode with more force, which to a degree is correct, HOWEVER, hot gasses also carry far less oxygen...an requirement of any internal combustion engine. So any gain is lost because less oxygen means less fuel can be burnt effectivly.

Basically, if this theory was sound (which it isnt) then every turbo and SC car out there had better remove the intercooler for a free boost in power....not likely.

Its complete rubbish...oh, and the exploding cylinder "test" they did has so many faults its not funny but the real big one is it relies on the same air temp as the explosion would be using the air in the "backyard", try doing it in a vacuum and see what happens.
