Ford e 450 passenger floor heat

[Bjsrv]

In doing research into how to improve the temps at my DW's feet in our Outlook I need one more answer.
Is the air conditioning on the e-450 supposed to only blow through the dash and not onto the floor.
I m ordering the insulation kit to improve the situation and may even add a vent if needed.

I doubled the insulation on the passenger side plus installed custom fit floor mats. Seems to have done the trick. The problem is the exhust manifold is just two inches from the doghouse on that side.

Ford has had problems with this issue since day one on the V-10 E450 and no one does a thing about it.

I ordered heat mat from Summit Racing to put under the floor in areas where there are the highest temps. It's supposed to be good to 1750 degrees. When I first started to pull back the carpet I couldn't believe there are areas where there is no insulation. No wonder the DW was complaining of the heat.

Bjsrv - can you provide additional info on the "heat mat"... My DW is voicing the same displeasure

Thanks

So far I have ordered two products. The one from Summit Racing is part# 050502. The one from JC Whitney is the one I got from this site but I think it may be more for sound than heat. I plan on wrapping the Banks headers, putting the 1700 degree material from Summit under the floor and doghouse, then using the JCWhitney insulation on the inside. Once the material arrives I will finalize the plan. JC Whitney said it would take 3-4 weeks. Not good enough for me. If the Summit material is better I will just order more.
Luckily I have the time and really enjoy correcting issues like this.

Today I installed the tunnel insulation on the doghouse and on areas under the floor where the exhaust heats the floor. We are going on a short trip Next week and we will test my work. I also added some of the home depot thermal insulation on the inside under the carpet on the DW side. I will replace that with the product from JC Whitney when it arrives.
I also put some of the 1700 degree tunnel insulation around the fuel lines on the drivers side. The Banks headers require extra coverage over the fuel lines and what was used in the original install isn't as good as the Summit stuff.

I used the J.C. Whitney 3/8" foil backed fiber material. I pulled the seats and floor carpet and put the mat down all across the cab. I also lined the underside of the engine cover. It made a world of difference. I later put on the Banks system with headers and that helped a bit more.

I finally got around to installing the JC Whitney heat/sound shield. My DW says it is much better. And that is on a trip from Vegas to Sedona in 90 plus heat. I only did her side though but if she's happy I'm done. Much quieter in cab also.
