With FMIC on, can the hood scoop be used for a CAI???
I ordered a FMIC for my TurboII S4 and I was wondering if anyone has tried to utilize the factory hood scoop for a CAI after the TMIC is gone????
Probably a dumb question, but I couldn't find anything about it when I ran a search.
Thanks!

okay, serious time.
What if I crammed a wide/thin vacumm attatchment under the scoop and connected it with PVC pipe. Do you think it would catch enough air to make a difference????
The only problem is, in order to actaully wedge that attatchment into the scoop and mount it there, I'd have to design the pipe seperate so that the hood can open and close. Make sense?
Someone tell me if I'm way off on this, but I think it could work.

why wouldnt it wouldnt make a great CAI if the intake was sealed to the scoop. the scoop is designed to flow large amounts of air over the stock top mount intercooler, so i dont see why it couldnt function well as a CAI too.

If that's gone, you should be able to route piping up to the intake box, and have a ram-air scoop.

Updates to come.

It does flow air, but unforunatley, the scoop is in a low-pressure zone along the hood. The scoop would've been more effective if it were placed closer to the nose of the car, but I think the styling dept may have had something against that (looked ugly). Subsequently, it's pretty inefficent at getting air in.
Building a CAI up there would be a very difficult task, since the CAI would suffer from the biggest shortcoming of a TMIC anyways - radiant heat rising. It would make the CAI terribly inefficent.
That and it would be very hard to get something to fit up there...

I'll scratch my head and see if I can come up with something else.
Thanks David,

At speed, it does work. How do I know? Because I am constantly picking mashed bugs out of my intercooler.

Camaros and Trans-AM WS6 owners can even verify this -- the Trans AM WS6s have their hood-scoop near the front of the car while Camaro SS owners have it positioned farther back, much like ours.
It is reported that of the 2 breeds, the WS6s are generally *slightly* quicker then SSs. Not much, but the difference is there.
It's a moot point, either way. There are too many disadvantages over advantages of using it as a cold-air induction point. If you really want cold air, someone should build a small hood scoop right behind the right headlight. You'll really see a difference on slightly modified TIIs.

That is a cool pic! where did you find it?
The real question is: Is it accurate? It looks to be pretty much like I imagined the air flow, but I don't know JACK about fluid dynamics..
I like how it even has the little missing/bent pieces in the bottom metal rail (the jack rail), just like mine!

well, i was searching for things like this, so i found it in about 2-3 different threads...
also, i still don't see why people use those headlight 'slits' for their CAI... based on this drawing, it seems like a waste.

People seem to forget that just because the arrows arent pointing towards the car doesnt make it a "low pressure zone" its just not seeing as much pressure as the front of the car. If you think your hoodscoop makes no difference put an n/a hood on your car and let me know how it works out for you. Im not arguing that this would be a useful mod but by no means would it be a complete waste of time.

this is sort of getting off topic though. about the hood vent, that's why blackbirdzach went with an FMIC in the first place.... because of HEAT SOAK. so, why not go somewhere else with it?

That "aerodynamic flow profile" is originally from a sales brochure, which means from an engineering point of view it's meaningless crap. Plus it's for a NA, not a Turbo, so it's irrelevant in this discussion.
