0.3367 to 0.4428 HP? Seriously? Thats one heck of a dyno setup that can measure stable to this level. I work in a dyno lab, and no matter how stable your engine appears to be running you will get fluctuations in power output. Surely the standard deviation of engine output over the measuring period greatly exceeds the difference in power recorded with and without this device.

If this number is brake output as measured on the dyno, then engine power is NOT increased by 20%. The frictional losses of the engine surely amount to at least 10 HP on an engine like the 300D has.

I think about the only conclusion you could draw from this is that the engine power increased by 0.1 HP, not 20%. How much electrical energy does it take to power this thing anyway?

What a joke. On a side note I had to laugh loudly at the 110 mpg(e) Ford Mustang at the naias yesterday.
