I got tired of having my right foot 100 degrees hotter than my left foot, so I just put up some of this DEI tunnel heat shield. Should keep from having baked right foot! Also helps not having an engine installed
I would recommend sealing the edges with a head resistant tape. The insulation can absorb moisture and oils and become less effective and even flammable in extreme cases.

If your foot is cooking, guess what the transmission oil is doing? Insulate the exhaust with metal heat shielding like they do from the factory on 100whp Miatas. The trans tunnel shielding definitely works but there is a real benefit to keeping the heat in the pipe.

A very good point indeed. Lol @ 100whp miatas, and true! Okay, well this material was thin enough I should still have plenty of spare clearance to add the downpipe heatshield. But... do the same concerns apply to those as such with turbo blankets? From what I have read, they can become oil saturated and ignite.
EDIT: I suppose I could fab up a heat shield that doesn't use a fabric material.
Insulating the exhaust pipe is going to do the most. You need air space in between each part/material otherwise it all heat soaks to a point. Then insulate the interior trans panel to catch the remaining heat that soaks through. High quality blankets are made of flame retardent material. It's the oil that will be the fuel to the fire. Just keep up on maintaining leaks and it's not a problem.
Yup, I understand its only the oil that burns. I'll have insulation on the inside as well, more than I already have added. My plan was to have basically a stainless sheet bent around the downpipe, with about 10mm of air between the downpipe and sheet. and then just clamped on at each end. It's also important to keep in mind that not only will leaks saturate the blanket but so can vapors, which are more difficult to avoid entirely without rerouting crankcase gasses into the engine, which will not be my crankcase ventilation/OCC solution this time around, but that's for a different thread entirely
to one of these. I believe the idea is to use it to isolate the exhaust from the transmission, and from the gas tank.
Yes.
Turbo blankets will make the turbo fail on a track car. The turbine side oil seal fails first and then the bearing. Ask any turbo rebuild shop what they know about blankets.
That thread has the best idea ever for inexpensive, light, and effective heat shields. Moti is the man for finding this stuff.
Pic is of my install of the shield without having the luxury off having the engine and trans out. It made a fantastic difference on long drives. Mind you, I live in SoFla and drive the car 2 hours one way to events in our summer heat. It was tough and I remember wedging a windshield sun visor between my leg and tunnel to keep it from baking my leg. After this shield install, no more sun visor to keep leg from baking!
