SD engines
Why were the SD engines discontinued?
Were the SD engines offered in medium duties or strictly heavy duties? |
Because they were crappy antiques.
The SDs were in the heavier mediums and heavies. Think F700 and up IIRC. |

The 534 twin turbo & intercooled engines that came out of a 46' motoryacht I'm restoring weighed 1800#, as much as a Cat 3208 turbodiesel. I'm told that when the throttles were planted forward, there was an enormous sucking sound, the rear of the boat would squat and the nose went for the sky. Within a second or two, the nose would slap down and that beast would take off--it was a 40kt boat, which is extremely fast for a vessel of this size especially when you consider that this upgrade was done in 1972. The downside, of course, is that it would consume three gallons per mile at full speed whereas a Cat of similar power output might consume only one gallon.
