Sorry for creating a new thread for this, but I didn't want it to get lost. This seems pretty darn important. I sent an email to Steeda and asked a few questions about the Cowl Induction hood. Here is the exchange and nested in there the answer to the hood flex.
Here is the answer I got and it appears to address the "hood flex/lift" I have been seeing in the forums.
I hope this helps and thanks for all the support in this forum.
Hi,
I am interested in your cowl induction hood for the 05 mustang. Your site says that the hood is functional. Could you provide pictures or a diagram on how the cowl induction works? Also, I have puchased your CAI already. Can the hood provide airflow to the CAI?
Thanks,
Greg

Greg,
Thank you for your interest in our products. After reading your question I think you may misunderstand the intended "function" of our hood. Our hood is not functional in the sense of the classic Cowl Induction set ups offered by GM in the late 60's. The only reason we even refer to it as a "Cowl Induction" style hood is because that is the style (looks not function) of hood that it is and when you use the term"cowl Induction" people know what it looks like. There is no (easy) way to direct airflow from the cowl area to your air intake set up, but that was not the reason we designed the hood. The reason we designed this hood, and in turn what makes our hood very "functional" is that it vents the high pressure area that builds up under the hood causing lift at high speeds. This is a VERY serious problem on the 2005 Mustang. In order for Ford to get the styling that they wanted for the car they needed to compromise aerodynamics significantly this compromise which gives the car its distinctive look causes an enormous amount of pressure to build up under the hood. We have already seen in racing where cars have literally ripped the stock hood (with 2 sets of good hood pins) off of the car, the Grand Am race at Daytona if you watched it was a good example of this. To sum it up yes, the hood is functional, no, it will not make you any more horsepower. Please give me a call if you were interested in purchasing one of these hoods, or if you have anymore specific parts questions.

OK, I absolutely love they styling of the new Stang, to me it's superior to nearly any other car on the road. Call me crazy, it's my feeling though. That said, am I the only one that feels that this is a error on Ford's part? I know that this car is ment for road use, but I've read about the hood lifting at 80, sometimes even lower. Here in Florida the interstate speedlimits are 70, and anyone who lives down here will tell you that if you're doing 80, you better be in the RIGHT lane, or you will be holding up traffic. It seems to me that this is a potentially very dangerous problem that Ford and all their genius needs to fix. Am I :crazy:?

Well, in all honesty I haven't heard of someone losing their hood on the street. I'm actually looking at hood pins though because I have noticed a little bit of jumping around 90, but not enough to worry me. It's not all the time either. 2 hood pins near the forward edges should resolve the jumpiness. Keep in mind that Steeda is trying to sell their hood, so they aren't exactly unbiased.

I haven't hear of them ripping off at highway speeds either, but for a sports car, muscle car, performance car, whatever... the car should able to go down the freeway without the hood getting skiddish.

Honestly, don't you think your hood is jumping because it already has pressure built up underneath it? Its jumping for a reason.

There just trying to sell their product. If this was just because of the aerodynamics of the car then what about every other car in the 60's 70's and 80's. The car doesn't have to be shaped like the steath bomber to have the hood stay in place.
Maybe this will be the first real issue with the new stang and maybe there will be a recall on it who knows. Bottom line IMO is that he's trying to scare you into buying a hood.

You might be right. I guess I am just not used to hoods shaking at high speeds on a sports car and this is the first actual reasonable explanation I heard.

If the hoods are jumping and they fly off and wack someone well its a flaw they should maybe have air flow to relieve any pressure underneath it or they may be liable but really has this ever happened ?
