So I'm still sniffing around this thing...
It makes no sense at all to make dyno runs without all the inputs i.e. fuel, air, etc. hooked up...
It was done after morning break but before lunch so they probably spent all morning prepping (or B.S.ing and eating donuts- yeah, I know what goes on in engineering departments)...
The SuperFlow dyno they use has the inputs for fuel consumption...
They
must have that data; after all the "article" is about fe???...
They do show air/fuel ratio (green bar at lower left corner)...
...but that was likely measured at the O2 sensor.
I think they opted not to provide it because then their whole scam piece would fall apart.
THEN this other red flag jumps out at me (I'm kinda like a bull that way)...
LOOK at their dyno chart:
I added the four straight lines, to illustrate something weird...
See where their text claims 291.8 ft/lb peak?
My line shows it's probably
281.8 ft/lb!
That also drags HP down to about 249... hella bunch less impressive than 260.8 ain't it. (HP line does appear to just cross the 250 mark but definitely doesn't make it, much less cross, the 260 mark.)
Just found more nonsense numbers not a paragraph away from each other:

Well, my math says 260.8 - 241.4 = 19.4
Hey, 19.4 isn't 16.
Actually MY figures are 249 - 241.4 = 7.6 (got 249 from the HP formula using rpm and torque values)
Oooooh... +3%!
They weren't off by much eh?
Think that, judging from the rest of it, there isn't at least a 3% margin of error here?
Fudge a few percent here, fudge a few percent there, pretty soon you have a +10% claim that the casual reader/chart lookiter will never see.
Who am I going to yell at... "By the author"?
Yeah, I wouldn't put my name on that P.O.S. either.
The whole purpose for the made-up "road test" was to provide cover for the damning dyno results.
How can a guy make an alert for magazine fraud like this go viral?

Man I just can't let it go.
I go to the K&N site and find:

Hmmm. If I was K&N and these really were my values...
and of course I got to see a copy of the "article" before publication...
I would have to make plenty of "corrections"...
No?
