Lets talk science, Stillen Gen3 Intake
 

Disclaimer: Not an engineer, I deal with molecules or smaller.

So can someone explain the physics that is occurring behind the Stillen intake? From my understanding longer tubes cause a reduced pressure within the tube due to increased drag. Reduced pressure typically means less power due to getting less air into the manifold. The only thing that I can account for in the power gain is colder air, reduced turbulence from the smooth surface of the piping, larger air filter. I think I am missing a key factor. Discuss.

I guess if they sucked it might actually be a good thing : )

Your physics sounds right to me. I think maybe add less resistance through the air filter to the list.

Yep. You want as little restriction on the intake side as possible.

Cold air takes less space than warm air, therefore in the combustion chamber you can fit more gas. More or less, this should be the idea behind CAIs.

Do you mean cold air is denser than warm air, so you can add more fuel to match the larger amount of O2 in the cylinder?

Overall, I haven't heard that they're much better than a K&N w/ a post MAF silicon tube.

But, they cost more money so they have to be better...right?....right?

:icon18: More my friend...much more. I think this is the funniest semi-accurate way I've ever seen a CAI explained. It's kind of like "Kids say the darndest things."

I laughed. He's definitely not wrong.

LoL..Kinda wrong, sorta right. LOL!

Bingo!

CAI for the 370 are all way over rated and over priced. Its not needed. Just drop some reusable K&N's in there.

This is how I feel & what I do
 

Notice how a car when viewed from the side is shaped like a wing. Much more air & pressure is under the car than over the car. Just like a plane's wing. Flat under car vs roof & over the car. One of the places that the car's pressure (under car) goes/escapes is up through that space in front of & toward the the two stock intake openings. I & the second person on the top 25 list(redline06) run with our air cleaners off. That's not on the street, just at the track. I think I & him get lots of cool pressurized air into my stock intakes. Being in the # one spot & him being second, that idea/set up might be working very well.

I use dry K&N filters. On the street & most of the time at the track.

The vast majority of the gains come from a higher flow filter.

There you go! :tup:

science? thought it was just to make the engine bay look like it had a turbo and intercooler piping.
