As far as I'm concerned, there isn't a whole lot of reasoned refutation of the SEV claims in this thread -- in fact, it reads more like a transcript from the Spanish Inquisition than a defense of rationalism.
To paraphrase GW Bush, "this question needs more study."
Now, why would so many Japanese enthusiasts fall on their swords over this one?

If I'm not mistaken, isn't the equation: Power (HP) = torque (lb-ft) * RPM / 5252
If that is the case (as long as RPM is in the numerator and the denominator is a constant), then all those dyno curves are bogus.
But aside from that, any company that says the have a performance mod to sell that can't be dyno'd for a VERY obscure reason (magnetosphere?????) is highly suspect! What about all the other rotating iron parts in the engine?
I wish this board had a little smiley face with a "BS" sign, so I could pull it out.

OK, guys, points were made at all ends of the spectrum...let's keep it civil and on-topic. I think most of us have seen that the SEV system, while VERY loosely based upon real-world physics (I still say the possibility is there with my wire mesh idea, as UL pointed out 
), is lacking in the ability to concretely show proof of claimed operation.
UL, is it just my imagination, or in the first image, left graph does the green dotted line actually jog back to the left while going down the page at several points? Hmmm, two different torque measurements for one RPM measurement....looks like I need to brush up on my quantum mechanics again
OK, so I didn't get the "no torque difference SHOULD equal no HP difference", but can I still get a consolation prize?

Nope MacGyver, Luis pointed it out so he gets the virtual cookie :-)
Simply put folks, this whole situation smells very familiar. You see, there's this condition whereby a sudden vacancy in the wallet causes a slight equilibrium problem (this is primarily a problem for men since we sit on our wallets :-). This equilibrium problem causes the brain to misinterpret the signals from the old "butt dyno" and leads the conscious mind to conclude that the car is indeed faster.
When combined with the well documented "Keeping up with the Jones'" syndrome (which apparently is not limited to the U.S.) one can see how a non-functioning automotive product can generate mass interest and sales.
While many have hinted at the money vacancy effect, I don't think any have explained it so succinctly and clearly as I have here. In light of this, I think I shall call it the "perceived mass of money" syndrome. I choose this name because of the apparent, but imagined, linkage between the lightening of the wallet and improvement of acceleration.
Big :-)

This whole thread reminds me of a few years ago when a friend of mine tried to get me to invest in a machine that produced more energy than it consumed. He claimed that the electric company would be buying the excess energy from me. I simply asked for documented proof, which could not be produced. I think SEV comes from a similar school.
