the new PSD specs out at close to the same torque as the CTD, but higher revs, so the PSD can deliver about 30-40 more HP than the cummins. problem is, ford won't be able to establish reliabilty until years from now, but if/when they do, the PSD will be one screem'n machine. that said, however tere's no way they can compete in the reliability dept with cummins, for the simple reasons that:
1. the essential CTD lower engine design has been around for decades and proven reliable by Father Time long before they started apearing in Dodge trucks.
2. The CTD in our trucks is a dumbed down version of the same engine used in continuous duty commercial applications at higher power levels.
3. Dodge/Cummins have established a statistically valid "average time to rebuild" life of 350,000 miles. For those aqauinted with statistics, that takes lots of engines out there in the field, and lots of failures to prove this number.
no amount of Ford and Chevy engineering dollars or customer service efforts can deliver this in the short term. It takes time and a sustained reputation in the market place to distinguish between an engine that provides long term reliability and one that gives only instant gratification.
