Rear Bumper getting Really Hot- 77 930 Turbo


Recommended Posts

Well they do get hot and radiate massive amounts of heat when you shut the engine off..... hard to say if it's too much on your vehicle over the net. Sorry I can't recall what heat shields are there but I'm sure somebody more helpful will be along shortly.

Although I have an '84 (ROW), it does have a heat shield (but believe the bumper is off a North American spec car. The part number for mine is 930-505-511-00, but you would have to have the bolt holes in the top front edge of the bumper to screw it on (3 holes), which use M6x10 bolts (part number 900-278-024-09) with A6,4 washers (part number N-011-524-7). The heat shield (Porsche OEM) is available through Pelican parts for about $178 US. Not sure if it would fit a '77 Turbo, as it only lists it starting at a '78 option.

Hope it helps.

Been there done that.....nevertheless many years ago I replaced the OEM bumper and installed a fiberglass one, not just for looks but mostly looking forward to cut some weight here and there., from time to time that area got so hot that even the paint was blistering and whatnot. Then I removed the bumper and installed insulating material (the reflective aluminum one) everywhere including bumper inners, the bases of the tail lights and everything else and since then the situation improved a little bit.........still an intense heating producing area.
