Under Car Heat Reflective Sheets
We had a topic recently about cockpit heat and how to address it. Many recomended the foilbacked interior insulation available to help address the issue.
I made the statement that heat reflection needed to be done before the heat was able to transfer through the floor and the heat that did needed to be contained in a good insulation.I still stand by this.
Today I found a good example of my theory when I went to change the oil for the first time in the wifes new Grand Cherokee. I found the neatest quilted aluminum insulation blanket I ever saw.The quilt is made of a heavy aluminum foil on both sides with a 1" diamond shaped pocket of insulation. It is about 3/8" thick and 18" wide and about 6' long.
Seems I'll be going to the Junk Yard and take these out of a couple of Grand Cherokee's to go under the Vette.
I believe they will go all of the way from the firewall to the rear of the cockpit, with one for each side. I will also put one of the new repo transmission blankets in when I do this part of the project.
If you need something to keep the heat out I believe this might be a good way to do it. If I can get one out I will post a picture. Thanks JIM

Re: Under Car Heat Reflective Sheets (PROSOUTH)
I was under the car today and was wondering if something like this would work. Would there be any problems doing this. It gets real hot down here in florida. Thanks for the tip Jim! :cheers:

Re: Under Car Heat Reflective Sheets (strat68)
This may give you some help/ideas. I needed a heat shield for my ex. pipe that runs close to the p.side composite rear spring (the d.side has the OE heatshield below the spring for the original "Y" pipe configuration). I got the GF to bring home some printing plates, which are very thin aluminum with one side shiny & the other covered in some sort of coating for etching. These sheets are easily cut with scissors, so I cut out a couple of bits & fitted them to the pipe with hose clips. Started the engine (1st turn of the key!!! Woo-hooo It lives!! :D ) & ran it for 35 mins to break the cam in. Afterwards I checked the spring for heat. The pipes were very hot (baked the paint on nicely), but the spring above the pipe was stone cold :) Other parts of the car near the pipes were warm/hot. I thought that the sheet may stop some heat being radiated/convected to the spring but was amazed at how well it worked (sometimes even Bubba jobs work out :lol: )
The sheet is very easily bent/shaped, so would be ideal for undercar insulation, especially above the pipes (that'll be job #157 on my list ;) ).

Re: Under Car Heat Reflective Sheets (PROSOUTH)
The same theory holds for the engine side of the evaporator box on the AC. If you have headers, you have 800 degree heat about an inch from the composite evap box that contains air that you are trying to cool to 50 degrees. Reflective insulation here is very effective.

Re: Under Car Heat Reflective Sheets (TTop Tony)
I run cut outs from my headers and was concerned about burning an hole under the seat where the exhaust exits the cut out.....so I used thermal blanket from Summit (DEI).....after cleaning under there...I put silicone gasket sealer on the blanket, stuck it to the underside, and riveted along the edges. Never peeled off and still there after major heat ups while uncapped and racing. :seeya Cappy

Re: Under Car Heat Reflective Sheets (Larry82)
If I recall correctly the blanket had screws or a push in buttons to hold it on. I'll look tomorrow.
Great idea for a piece of this to go on my evaporator box on the AC. I had already planned on redoing my A/C box with new seals and a good cleaning of the coil and a new heater core with blower moter while I have the engine out.
I'll try and take a picture of her Jeep if I can get in before dark tomorrow.

Re: Under Car Heat Reflective Sheets (PROSOUTH)
This is pretty cool. I bet a lot of the heat problems would be solved specially with headers. I'm trying to find someone to help me run dual cats in my car and I was a bit concerned about not having any shielding over the cats but this might do the trick.
