I have an 06 GT convertible that I am thinking of converting. I do not like the GT500 hood, so I plan on keeping the stock hood. (PERTANOand555*, I love the look of your conversions!) Although I want to keep my stock hood, I am concerned about an article that I read that indicated the reason the vents are in the GT500 hood is twofold: 1. Heat Extraction; 2. Allow build-up of air under hood to excape. Apparantly, the larger grill of the GT500 fascia allows more air build-up under the hood,and at high speeds, increases the chance of hood lift-off. I am really concerned about this because I have experienced my hood becoming unhatched twice while driving at speeds at 90-95mph.

I've had the car up to 145mph on one occasion and 125mph a few other times with no problems at all. Not even hood shake like others experience. At the strip it was trapping at 111mph with no concerns either. So I guess the point is you don't havea problem.

Thanks, that is a relief. I really like the look of the stock hood with the GT500 fascia! Was wondering if you had to modify/trim the GT500 grill to fit under the lower profile of the stock GT hood?

I agree. I believe I read the same article that you did and "once the concept car's front end was redesigned to achieve upper and lower grille openings, it was discovered that the more aggressive design[/b] actually created a negative effect on aerodynamics. So engineers who had faced similar design[/b] versus air management issues during the development of the Ford GT simply went back to their lessons learned from that program and applied some of the same science to fix the problem without compromising a beautiful design[/b]. So the GT500's front splitter[/b] was designed quickly and efficiently to improve airflow while adding that desired purposeful look."

So it seems your stock hood is not a problem at all except for heat extraction. I certainly, though, would be sure to install the splitter which was specifically developed to work in conjunction with the upper and lower grille design.

Redfire 281, thanks for the info!
