Heres a hood vent that I designed on Google Sketchup. With paint I may have $10 in these. I have all the holes drilled out and ready to weld a little. They are 14 1/2" on the long side x 12" on the short side and 8" wide. The ridges are going to be 3/4 X 3/4 angle with holes drilled into the side facing windshield . They really shouldn't allow water to enter the engine bay. Let me know what you guys think

 

Heres a little closer image..

 

I dont see any problems with your design,
I might borrow the design when i get around to putting a new hood on if you dont mind

what are you using to drill the holes and keep them in line?

 

Very nice, I'd buy those.

 

Go right ahead and use the design. as far as measuring just a tape measure. The actual holes in the ridges are easy. I just turned the angle over with one edge facing up. Marked your distance. Then go to drill press and just let the bit slide down the edge facing up and you will have a consistent distance plus the hole will be elevated up from the hood surface to keep water from entering the engine bay. of course this is being done before welding to the actual plate .i will post some pics up tomorrow when I get back in the garage

 

You didnt actually make this yet? Looks good but this should be in chat if it wasn't fabbed up yet

 

Moves to chat.

 

I have started these just not finished. I will repost in the fab section and add all pics at once .. Sorry my bad

 

Always seemed to me like you could cut a rectangles out the hood and weld or rivet in upside down broiler pans for pretty good looking vents/louvers.

 

....and you could totally cook some brats on the trail, NICE

 

I've actually thought the same thin g myself. When im at home depot or even sometimes at home goods i look at stuff and see if its usable.

 

Great job I think I'm going to do this as my next project for my 96 XJatittude..
After I install my Flowmaster Super 44..An again great design...

 

Well crap
I wish I had thought of those...lol

 

I am soo going to pick up two broiler pans and do this .
