I was reading a thread over at Dieselstop on why the PSD can't clear 500HP. Some are honest and admit the shortcomings of the engine, others say things like "no aftermarket". Here's something to think about:
The reason we CTD guys have a place like Enterprise Engine is because of the CTD. If the PSD or DMAX was a better motor, Enterprise would have used THAT as the foundation for their business.
The reason their is such a market for CTD performance is because it is so easy. We don't need to upgrade much to get more power! I mean, a plug in box and WHAM! you have 60-100 more hp for cheap. Not so PSD and DMAX. Consider the things that we BOMB:
1) Injectors
2) Box
3) Turbo(s)
That's all it takes for a lot of power! Now if you want to add SERIOUS HP:
1) Cam
2) O-ring
3) Custom Pump (maybe P-pump)
That's it! No rocker arms or valvetrain issues! No bottom end concerns! For once, just think about all the things that we DON'T have to touch when we add HP! That's what's most amazing to *ME*.
There was a guy on the Ford site saying stuff about how the PSD could easily run with the CTD if it had an aftermarket as popular as say, the big block chevy--in other word, If he could replace all the stock components (block, crank, rods, heads, valvetrain) with forged/billet/alloy components, THEN it would be as strong as a CTD.
It continues to baffle me how for relatively little money I could build an insanely powerful daily driver that will STILL get decent fuel mileage and last 300K+.
What's the last big block Chevy you saw that had over 500 HP (and almost double that tq), BUT idled smoothly, got over 13mpg, AND would last for many miles??
I am building a motor for my '69 Coronet, and I can only HOPE to get 10+mpg in an engine that will barely idle at that power level. Never mind that it MIGHT go 30K before needing a rebuild!
I stick to my earlier statement that a Cummins is the best VALUE in all of hotrodding. You simply can't get more for your hotrod dollar anywhere else.
