DIY - Heat resistance plate - Exhaust pipe front

Hello e9 Freunden,

I would like to make a DIY for the heat insulation of the exhaust:

The heat resistance plate of the BMW e28 / e24 / e12 serie are also useful for our e9.

It will keep the heat radiation away from your passenger.

The part number is 51 48 1 832 850
Still available by BMW.

See attached pictures. Not yet finished, but very useful piece of heat resistance aluminium.

That looks like it would be a great addition - i look forward to seeing how it works out.

Guys I am starting the assembly of my project, I see that the firewall/insulation is in 3 parts the upper part is without adhesive, any recomendation for that? any glue or adhesive for that one?? Appreciate your feedback

Great intiative!

There are various members who have installed it and are happy with it.

Reflecting some options of what members have done would be good - our forum itself has some examples.

I installed mine using the transmission bracket, and then cut some unused bushings and wedged them in the front and back to keep the ends of the heat shield from flapping and hitting the underside of the car.

i recomend you do proper engineering and use correct fixing points, the plate has the holes for it, you can use welded studs or rivets, better if you make it 10mm away from body so air can pass in between and help cooling, my 0,5€

you can find the deatils in this thread...

and here the pics:




rear as stated, using the gearbox frame:

mediaum and front using welded studs; plus a 10mm distancer between the plate and the body; this leaves an air layer for cooling the plate and limiting the radiation

good engineering in this one

erik was the first one i saw this solution from,
you must have some pics too

i do have some pics indeed...

I installed it with an additional mouting point located 137x70 mm from the sides. I believe i also snipped a bit off & reshaped (see the hammer marks) the edge where it turns up into the engine compartment to clear the frame rails, though i see others managed to do without:

Then I installed 2 weld nuts, to be able to fix the part with at least 3 points:
first weldnut installed and the 2nd weldnut drawn out with pencil marks. 3rd point is the already existing transmission support bolt.

But everyone's solution is interesting. Even the ones that are perhaps less 'engineery' ; the one from @Ohmess benefits from being quicker to install. My solutions take the longest time to build And I'm far away from driving as a result of my quest for engineering perfection!

Building on the heat containment theme:
I also added this part, stomped out of an E60/E61 heatshield; it has a fully contoured shape with an airgap ~10mm offset of the body + driveline

some suggestions if you want to build it yourself:

I started out by making the main form with simple wooden jig:

Yup. Poor engineering. Installed nine years ago. Took me ten minutes. No problems.

love it,

love the idea. i remember somebody posting this idea 2 or 3 years ago but don't remember seeing the result. i bought the e28 (double metal) piece, wondering if i could get it to fit into the coupe tunnel.
