I have some Sunbird Turbo hood vents that I am going to be installing on my 85 GT.
I have never done a bodywork project like this before. (knowing where to place them, getting them lined up appropriately, measuring & cutting the holes in the front hood, etc...)
I would like to see a few pics of those who have done this. (Grand Am & Firebird vents are also welcome)
Also, do you have any pointers/suggestions on the install? (especially on how to determine where to place them in the front of the hood / spacing, etc.)`
Thanks, Kit

I used a different style vent... but the best advice I can give you is first, make sure the entire vent is behind the radiator (I know, seems obvious), and don't go back so far that you're cutting into the area that seats on the rubber seal of the spare tire compartment.[This message has been edited by Patrick (edited 08-07-2022).]

I don't particularly like the "Glue-on" look of a lot of the vents. I prefer where the vent is ducted into the hood a bit. I also really like using the Defrost (Dash) vent as the grill for a hood vent- possibly combining it with a slight "tunneling".....

In a nutshell, you'll notice that with all of the vents shown above, the opening is no higher than the top of the headlight doors. Keep your vents between the headlights and you'll be fine.
Basically follow the curves where the trunk seal sits that I marked in green. You can see the area between the headlights where you can cut and still be in the radiator area and not in the spare tire area.

Wow, those are quite close together.
I usually see more spacing between the vents.
Looks great though! 
Thanks for the pic.

I completely understand why qwikgta installed the vents where he did, as it looks great! However, if I was to have used those style vents, I think I personally would've mounted them as far back as possible... as I wouldn't want any part of the vents to be in front of and/or on top of the radiator. It's the pressure build up behind the rad and in front of the spare tire compartment that needs to be reduced. This image sort of shows approximately where I'd try locating the rear mounting holes.

The area above, beside, and behind the radiator are all the same high pressure area (this is why headlight covers pop up). Vents in any of these directions/areas can help reduce the pressure build up and be effective vents.

There are two factors in play here... reducing overall air pressure build up under the nose, and effectively venting hot air (as opposed to air that hasn't gone through the radiator yet). I installed my hood vents more to aid with cooling than to prevent front end lift. (I seldom go fast enough for there to ever be an issue!)
I want as much vented air as possible to have gone through the radiator.
Yes, it's conceivable that their placement doesn't make any discernible difference in the cooling effect of the vents... but I don't know for sure, which is why I lean towards moving the vents rearward of the radiator as far as they can go.
