I can tell you from looking at many dyno charts some tendencies or trends
I've seen when looking at different intakes used.
I'll focus my comments to street applications here
and
I'll stick to the most popular choices used
Lets start with TFS & Edelbrock
The difference between them is not all that great but I believe in most
cases the Edel will edge out the TFS by a small margin.
Now ... both of these brands offer a long and mid length runner upper
The longer runner choice of either will offer a bit more low end torque
but
Will peter out sooner in the high end of the power curve
The mid length choices will do just the opposite
Another popular choice is the oem Cobra
Nice low end torque but it falls off pretty quick
however
Some have been able to help its high end with porting

Here's the best place to look for intake info IMO!

i read a lot of books and the edelbrock performer always seems to come out on top. the holley systemax is supposed to be the highest flowing but you lose a lot of torgue
The reason you don't see more Edel intakes is simply because .....
you can run a TFS for less money.
The difference in performance is not all that great
however
Something a lot of peeps don't consider
A lot of the time ... Edels can be run with NO spacer
I did that very thing with my combo
Soooo ... you then gotta ask yourself ...
whats the difference in cost when you add in the spacer

Don't you have to replace the stock hood with a taller one when you go with the Edelbrock intake?
If a new hood is required, then considering that cost would be wise.

Ive always been curious about the runner size, runner length, and tbody opening of each intake versus another. Like the Trickflow street intake has a 75mm opening, 15" inch runners and 2.0 x1.2 runner size, where is the trackheat has a 75mm opening, 12" runners and 2.0 x1.2. I never could find the runner size,tbody opening, or length on the holley systemax or other intakes. I know though longer runner intakes produce better torque down low,but fall short in the higher rpms. Shorter runners produce more power at higher rpms, but fall a bit short in torque .I believe runner size has alot to do with it though to,seeing as how well the performer intake performs against others.I'm always open for learning more on performance.

i got the rpm2, it hits my hood a little, its b/c i have to washers under my motor mounts so my shorties clear. it still closes, i just need to cut some of the hood brace by the bolt on the intake.
