A couple of things to throw in here guys.....
First, the Roush grill won't work. I have one sitting here and not only doesn't it fit, modifying it TO fit, doesn't look easy. The Roush grill is a no-go.
Many people keep saying/thinking that this is an issue of getting heat out of the engine bay. Not really. The heat in the engine bay isn't really the culprit (directly) for the overheating. The issue is airflow through the radiator. To maximize airflow through the radiator you need two things:
1) You need to maximize the area in which the car can "ingest" the air. Obstructions in front of the radiator need to be removed allowing the maximum flow of air to present itself to the radiator.
2) After the air has been ingested by the radiator - you need to expedite it's path out and away from the car.... enabling "new air" to flow through the radiator. In OEM trim, the air flows through the radiator and then into the engine compartment and then must follow some odd-ball, indirect path to find the bottom of the car and the low pressure zone under the car before finally exiting. Presenting more frontal area to the radiator only compounds the problem of trying to get rid of it.
Enough credit is not given to the Tiger Racing Hood for engine cooling. It has been mentioned here that the Tiger hood first and foremost improves downforce. Correct... but how is that happening? The reason is that the air that flows through the radiator is literally sucked out and over the hood and then the top of the car. This is a fast-path for air that noramlly finds it's way under the car to the low pressure area - and disturbs this low pressure area.
To the OP. I feel your pain, trust me. I guess you really have to ask yourself that in any given year, how many times are you going to track the car in 90+ degree weather. For each of these times, you need to take an additional 5-minutes to remove the grill and 1-minute to put it back at the end of the day. Should you have to do this on a $45K advertised track car? No. But, at the end of the day this really is not a big deal.

Paging Drew! Didn't 06GT put a GT surround in with the Roush grille inside it?? The Roush grille won't go directly into the Boss as it's designed to go into the GT. However, it's my understanding that the GT grille surround attaches directly into the openings on the Boss.
#23
??? You know you need a GT surround right? There are other bar grilles besides the Roush if you don't like that one. Drew has the American Muscle version.

My only hesitation then at this point is the potential "water issues" for a daily driven track car. Will significant rain running into the engine bay, or water from a typical gas station car wash cause problems either for the painted hood or the engine? It's not that I normally drive the Boss on rainy days, but I also won't leave my Mustangs in the garage just because there's a chance of rain. In this part of the country rain's possible at least half the days during spring/summer. I prefer not to spend the time hand washing my cars since with our weather you're washing them a couple times a week to keep them clean.

I just got the white one (on top) in today. It will work out of the box. Just need to have it painted....

Maybe it's just the picture, but the shape looks slightly different than the BOSS grill. Regardless, if you're saying it works that's good enough for me. Do you have a link to the part?
Can't tell for sure from the pic, but I'm thinking the white on black might actually look good in a Kona Blue/White color scheme... or does the white need paint to look presentable?

I have been saying this for awhile.....
Open up the grill (302s grill will be fine), tiger racing hood, air to oil cooler, and you will be good to go. If you want to get crazy add the s radiator and maybe some fans.....
I for one see extreme ambient temps at the track. I live in the se....

I think that looks sharp. It could have had that configuration stock. I'm now officially sold on the white grill-surround for the KB scheme.
Did you take that pic Rick? If so, what were your impressions seeing it in person?

That was the car I drove at Track Attack. They had a professional photographer taking photos and they give you a Boss Track Attack flash drive with all the photos on it. I liked the white surround but doubt I'll do it. I'd do the white rear spoiler first.

This is a great thread and good suggestions. I think my next move will be a bar/billet grille with GT surround for track days. If that doesn't cut it on the 90+ days I will probably opt for the Tiger hood.

Only 2 track days with my Boss. One at 90, one above 85. No issues. I know you push your Boss harder than me,
but as I get better I will do something with the grill, if it becomes a problem.

Another simple solution for people that do not want to change hoods at the moment is to pull the weather stripping at the back of the hood. I pulled mine when I installed the new gillie and reduced temps 15-20 degrees. Outside temps were cooler then some of my other runs but I did see a difference. I will not know for sure until next summer when the heat returns but pulling the weather strip takes a couple of minutes and does provide some air flow, enough to make a difference? not sure yet.
