I had a long discussion the other day with a gentleman and he questioned if the Powerstroke uses "Powder Metal" or "Forged Steel" connecting rods.
I was told that if in fact the Powder Metal Rods are used, any additional hp/torque other than stock would be most detrimental to the health of the motor?
Anyone out there have an idea?

Musta been a cummings fan,
Ive heard dodge guys bragging about how the bottom end of a cummings is much stronger than the 7.3.
But, i dunno. |

Oct. 16,2000 was the introduction date of PMR. Prior to that Forged rods were used. 6.0 all have PMR. Powdered metal parts is nothing new, it has been around for a very long time. PMR in the 7.3 are not nearly as strong as forged, but they will take mild mods. Cummins 5.9b is in fact much stronger bottom end compared to PSD. But I know of nobody who has broken, or blown a crank through the pan in a PSD. The 5.9b is way overengineered for the power ratings it is used in te light truck market.
96F250,PSD,SC,LWB,4X4,lots of mods

The PMR rods will hold up to somewhere in the range of 415-425RWHP. If you are at that level you are driving on borrowed time. If you are running that kind of power I would spend the money of having Forged rods installed. You will come out ahead vs. having to deal with a porthole in your block. |
