Topic: Decided on my next mod!

[MyBigToy]

I finally finished this mod last weekend. I'm still tweaking things to make sure the louvers stay in place. Now to get the truck cleaned up and get some pictures.

How about some like the old Camaro RS's or GTO's..

Have you seen these?

On another thought I wonder if the hood vents would look good on a stock Avalanche hood?

I have been looking for a way to vent underhood heat, much as the cowl hood did for my last truck. I did not like the engine heat vented right where the air is picked up for the interior though. No cowl hood for this one.
I did lots of looking for something that might work. There are several louvered panels available, but I'm not so happy with their appearance or methods to attach them.
I came across this install : Oman 4x4 Hood Vent Install and the one in this thread. Both were helpful.
My search for new louvers ended when I found out they have been discontinued and the few that are still out there underwent a substantial price increase. $160 plus freight was more than I was willing to spend.
One local yard had two Pontiac Grand Prix the correct years. They had checked the green one last week and forgot to call me to tell me they were gone. I saw that they had a white 1996 hood with louvers. They had not checked out that one. I offered to come over and check it out.
Over the hill and through the snow! It was iced over and had six inches of snow on it, but they were both there. The hood was 80% , but I knew the guy running this yard and he was willing to let them go. I shoveled the hood off , pulled them and $20 later they were mine.
Returning home I coated them with paint stripper and removed three layers of white paint. I'd say this car had been repainted more than once. Down to original paint, I scuffed them good and gave them a coat of black satin Krylon Fusion.



There are a few minor imperfections, but they are not too bad.

My son arrived home from school and off we went to the shop to get inside. Masking tape and below 20 degrees outside just don't mix well.
I had already laid out templates and spacing earlier so once masked off things went pretty quickly.
Sixteen holes drilled, there was no going back now.



I would have liked them farther back and more toward the outside, but 2005 hood braces hindered any other positions. This was the only place with space enough on the underside. These need to be functional, so there was no other option.
I did not realize that I was out of metal blades for the jigsaw, so a run to Wally world slowed the progress a little. Once we returned I cut out the big holes. Then I installed the hood insulation and chalked it to cut holes on the interior. Once that was ready I painted the raw edges of the hood , trimmed up some 1/2" neoprene to fill the void and hold some tension on the screws, attached the screws with fender washers and reinstalled the hood insulation.



The open area of both add up to 12.5 square inches (.25"x5"x5x2 ) The design of the louvers creates a low pressure zone behind each opening. At speed that should draw heat out. At low speeds at least it has some where to go.



Finished after dark. I guess I get to see what I have done on the morning. 
I checked them after I parked. If nothing else they make great handwarmers 

Thanks for helping me vent!
