A recent 5.0 Magazine article had a shootout of 4 intake manifolds,
which confused me somewhat. I was under the impression that the intake
runner length and design give the intake a specific power band, which
the rest of the engine components should match. The Holley and Trick
Flow pieces are their respective company's higher rpm pieces, and the
others were the BBK and Ford GT-40, which show a power band lower in
the rpm range.
The test used the same cam for all intakes which surprised me.
Shouldn't an accurate test use a cam that matches the rpm range of the
intakes?
Well, you did say that i was an intake manifold shootout..... not a cam
shootout - not a head shootout.... simply an intake manifold shootout.
They pick a base engine configuration..... to accurately compare two or more
things, you need a baseline that all results can be compared to.
After that, it goes something like this... the author gathers up all the
"free" manifolds he can find.... it doesn't matter if they should even be
considered for the base engine or not.... the price is what he is looking
at.... if he gets to keep them is even better. They bolt on consecutive
manifolds and dyno the car.... whether the manifold should even be
considered for the base engine or not.
They take some pics, make a couple of charts, shoot some shit and, when they
get to the summation, they are very careful to avoid treading on any toes.
Joe Consumer sees the cover of the rag....it screams "INTAKE MANIFOLD
SHOOTOUT!!!".. Joe Consumer buys the magazine...mission accomplished.
When selecting any parts, it is vitally important to consider how the entire
package is expected to work.... This magazine article was not designed to
sell intake manifolds.... it was designed to sell magazines - as are MOST
magazine articles...

Warman, I fear you are letting your cynicism get the better of you....
Never mind everything you say, there, is true.. you're like the grinch.
Hey, I love ya, man!
;)
Steve, take most of those articles they way that {I hope} you take WWE...

Last I remember Summit made two different Trick Flow intakes,
longer one for street and shorter for high RPM track. Same thing with
the Edelbrock which runs neck and neck with the Summit.
Nice to see you're back... we did miss you. I do hope you weren't ill.

I've taken Curmudgeon courses, and just couldn't get the hang of it, so
I took a survey course simply called Prick as an elective, and loved
it. (Uh-oh, that's gonna cost me.......)
But back to my inquiry; If I was building a street 5.0 for use with
an automatic, I would be better served with an intake manifold setup
that offered a lower rpm power band, and choose a cam that also offers
lower rpm power, no? While I'm still several months away from needing
to make a final decision on components, I was very interested in the
"shootout".
If the magazines were more interested in offering truly useful info,
wouldn't they do two different comparisons, comparing the lower
rpm\higher torque against each other, and the higher horsepower intakes
against their competitors using cams and heads that better matched the
intakes? (or am I asking too much)
I have a mouse in my pocket...... after your recent peccadillo with the
hu...hu... hu word, don't get too frisky 8^)
