Since I'm rebuilding the belly pans, I figured the air dam belly pan should git upgraded as well. The new air dam belly pan is made from the former engine bay belly pan. All the metal stud reinforced 2x4 wood crossbeams have been replaced with slotted angles. I think I'm around 15lbs lighter in weight overall now.

Since I have slotted angles now, I can bolt in different configurations easily.


I'm not sure if the next version will be made from aluminum diamond plate like the rest of the belly pans but we'll see...

A quick run yielded a spike in my underhood temps. Normally (without the new belly pan) temps were around 130 degrees F (measured in between the top of the engine and the bottom of the hood). With the new belly pan installed, temps were in the 170's F!

Unbolted the belly pan and sprayed it with some flat black paint as an experiment to see if the underhood temps will change or not.

It's amazing that you got that difference with a coat of paint.

So— scrape it off for some A-B-A testing?

Painted only on the top? The expression keep the shiny side up no longer applies to you. You're exempt, Okay?

Are the wheelwells separated from the engine bay? Are you going to re-use the front wheel skirts?

I believe the shiny aluminum was reflecting infrared radiation back into the engine bay like a mirror. I experienced this with the aluminum flashing I had on the previous engine belly pan. All the black paint allowed was the absorption of the radiation and the unpainted side of the diamond plate disperses the heat into the airflow.

Not looking to do an ABA testing session. The closest experiment is fer others understand is to allow the sun to relect off of some diamond plate onto their face, cover the diamond plate with a sheet of newspaper, and then take the newspaper off.

I've never had front wheel skirts before. Perhaps you have my rig mixed up with someone elses? I'm not understanding the wheelwell question...

Whoosh goes the joke. Oh well, I've bombed before.

I had a bad feeling about that just as I pushed the button. I seem to remember a high-angle shot taken at night in a parking lot. Maybe I'm thinking of aerohead. Trying to dig my way out of the hole, I found this:


http://ecomodder.com/forum/showthread.php/hummvee-front-wheel-skirts-armored-31205.html

I see now it's not a T-100. I mentioned the wheelwells because they are available/an opportunity for improvement.

The belly pans are completed fer now! I ended up reusing the steel flashing that was on the previous belly pan to fill in the middle section. If it rattles too much, I'll probably use some of the black Coroplast to help quiet it down.





Painted the section below the catalytic converter/exhaust system flat black...

That's a lot of work to go to so you don't have to lower your truck 4".
