Intake scoops

Can anyone really justify spending $100 bones on scoops? I just can't see the immediate need for them in any application, but prove me wrong!

Nobody really can. It might help push just a little more air up into your intake snorkel at higher speeds, but really they're for looks. Especially if you powder coat them a cool color so they're more noticeable behind your grilles. It has the same effect on performance that a carbon diffuser does for weight savings.... almost none at all.

^this. Though im a sucker for Red scoops behind matte black grillles.

I've elected not to use them due to the airflow they'd take from the cooling system for minimal gains at best. From pictures I've seen, I'm also not a fan of their design and the sharp 90 degree angles that would potentially create turbulence.

Cyba Scoops.... honestly. No point in spending 100 on something you can get for 40, and works JUST as good. I am beyond happy with my purchase of them

macht schnell has a nice smooth radius to their scoops

You're right, that makes a lot more sense to me! Might be a mod worth doing if I decide to go back to the OEM intake or do the Mr. 5 intake and put in dual oil coolers. Will have to see what the temps do first though.

You cannot force more air into your intake tract. Period. Done. Even if you put a big scoop in the front of the car that "directs" aide into the intake area it won't make any difference.

Sounds like you have solid experiment results to back up your definitive statement. Care to share?

I searched these forums for "cyba scoops", came across the following thread:
http://www.1addicts.com/forums/showt...ght=cyba+scoop

doing a tad of reading down, i came across this:

http://www.paladinmicro.com/documents/RamAirMyth.pdf

Same concept. "Forcing" air into the intake area is the same idea as "ram air" in this case.

Also, for another matter, the amount of air you PULL into the car is controlled directly by the cars exhaust tract and the wastegates. There is no way to push more air past the turbine blades.

2nd edit: that's not to say I don't think they look cool and for $40 and a can of white spray paint I couldn't have a nice subtle detail piece, but that $40 could easily be spent elsewhere right now.

so based on this logic then the DCI should be useless, right? or what about all the scoops and ducts that are designed into high performance cars. are they only for looks and not function? just because bmw didn't design a more efficient air intake for their daily driven cars doesn't mean you can't improve on their design for higher performance. there's a good argument to be made for the blockage the scoops create over the radiator but imo at higher speeds it'll definitely force air into the tract. whether that is of any benefit is the question. common sense says it should but I am not a thermo dynamics engineer so I can't say definitively it does

Its more of a fluid dynamics situation but whatever.

DCI is very different than scoops. The filter of the DCI is a larger total filtering surface area, where as scoops only "direct" (or so the thought is). Even with a DCI you are "pulling" against the filter surface area, because, again, the way the intake system functions in a turbocharged car is with the exhaust gasses spinning the hot side of the turbo, which then spins the turbine in the cold side of the turbo. The wastegate then regulates how much of that exhaust goes through the hot side and causes the cold side to "suck in."

There is no "forcing air in" into a turbo engine. Period.

No, but you can force are in to a plenum (airbox) that makes it easier for the turbos to breath, especially if that becomes a restriction at higher boost levels.

Suck on a straw, then have somebody place an air nozzle on the end of that straw and try it again...

Wouldn't help you off the line, but could potentially provide gains at higher speeds.

More efficient air supply, less resistance on the turbos, less resistance on the turbos, less restriction on the exhaust gasses escaping....

All of this would obviously only be valid if...
1. there is a restriction
2. I knew what I was talking about

I can already assure you that I've taken more courses and had more experience with fluid dynamics than you have based on your comments and opinions so far.

You seem to be quite adamant that you are right and it makes a difference solely off a "feeling" that it SHOULD matter.

like I said you are still not getting it. my point was, you shouldn't be making such sweeping and definitive statements based on loose anecdotal evidence found on forums. just because someone posted something saying ramair is a myth doesn't make it fact. also your comment about how you may have taken more courses on fluid dynamics than me just proves my point. you don't know me but you're willing to make sweeping unsupportive statements. all the same to me, you can believe what you want

I am making assumptions about you based on the opinions you have expressed about the topic in this thread. If you are in fact just trolling the shit out of me, bravo sir, but i am trying to help OP and other users who truly believe that these scoops are a performance improvement instead of a cosmetic addition.

On the other hand, could you please add some supporting evidence that these scoops do in fact work aside from you saying "it'll definately force more air into the intake"?

The point is not that they dont direct air. They sure do, they certainly do direct air away from the radiator. The point is that you cannot FORCE AIR into a turbocharger. If you cant grasp this truth, than you obviously dont understand how a turbocharger works.
