Sintered, powder metal? I've got a pic of a 996 crank and I see the wide flashing line -- ground away of course -- that is typical of a hot forged part. Cast parts typically have a thin flashing line and powdered metal a very thin one or none at all.

I'm surprised and frankly though I mean this in a friendly way still a bit doubtful the 996 crank's composed of sintered metal.

Sincerely,

OMG the sky is falling. Porsche used sintered powdered metal cranks and connecting rods in the M96 motors!!

Exactly what does everyone think is in every other manufacturers engines?

Sintered powder metal rods common. Cast iron cranks ditto. Just sintered powder metal crank caught me a bit by surprise and with some disbelief.

I thought I had read the cranks were forged as I had read the rods were sintered powder metal and then "cracked". Porsche I believe perfected this cracked technique.

Sincerely,

Macster.

If we knew I doubt we would ask.

I too do not think it is accurate. A sintered crank would not be able to handle any tangential torque loads across it.
