Hood vents
http://xjtalk.com/images/special/Photo_110409_011.jpg
Had some free time yesterday so I was able to install some vents in my hood to help drop the underhood temps a little... Let me know what you guys think...
To start here are pictures of the materials I purchased for the vent. Grill-O-Sheets for the mesh

and door edge molding from any local autopart store.

In this picture it will show the cut-out locations... I did try to make the center line and the top line run parallel to the center line and in the upper edge of the hood as well...

After I laid out my masking tape I measured and drew out my two triangles... then I measured 1 1/2 from the top outer points and drew a line down and measured 3" up from the bottom points and drew a straight line out... I basically just cut the points off...

after grinding down the edges and priming the bare metal I put the door edge molding on... then from under the hood I put the mesh material up against the hood and cut it down a little... After scuffing, priming and painting the mesh I secured them to the hood with black silicone and masking tape to hold them up overnight.

The next morning I pulled off the tape and there was my finished homemade hood vents...

it was pretty easy, just a little scary making the first cut but overall it can be done in just a few hours... Obviously you can also come up with your own shapes and designs... and if it concerns you, drip pans should be a piece of cake to make if you got this far... Hope this helps.
I'll be hitting all my electrical connections with di-electric to prevent any problems with rain but if that doesn't work I'll add some drip pans under each side... We'll see what happens after a couple of trips in the rain...

Re: Hood vents
I may be doing that to mine in the near future. I really like it.
Let me know how it does at lowering the temp.

Re: Hood vents
so its been a couple months have you noticed a big change in temp?
they look good btw - also you could have used jbweld or something like that to hold them on too.

Re: Hood vents
The vents combined with the electric fan bypass drops temps quite a bit and since I've done it I haven't had any cyl 3 misfires or rough idles on start up from heat soak... I usually leave the fan on in town when I'm running errands and turn it off (let the computer control it) on longer hwy runs... No problems with rain so I never did drip pans and I probably won't...
And as far a JB weld goes, that was an option but since the black rtv is good to 450 degrees and a lot easier to take off if needed I went that route... They're still up there and not coming loose at all...
