Picked up an 07 E450 cube van a few weeks back; have been told that the vans use a de tuned 250hp version of the psd, does anyone know for sure?

Yes, the vans have a detuned 6.0, it has to do with cooling and the limited space for the engine. Not that I noticed any difference between the 2004 van with a 6.0 and the 2005 crew cab pickup with a 6.0. I've owned both.

rray, tnks I cannot imagine what the full monty is like-as it is now this thing gets up and goes, another 100 hp must be insanity.

Take a look and see if your engine has an intercooler (charge air cooler). Because of a lack of packaging space, I don't believe the 7.3s in the vans did - thus, their lower rating. It may be the same situation with the 6.0s.

Whats it look like Rusty, small radiator near the turbo?

Was told that Ford reintroduced the 6.0 as the 6.4 would not fit into the vans because of the cooling arrangement, don't know if this is accurate.

It looks like another radiator. Follow the air piping coming off the turbo. If the compressor discharge pipe goes forward into a "radiator" (actually, an intercooler to cool the charge air) and then back into the engine intake, you have an intercooled engine. Conversely, if the compressor discharge pipe goes directly from the turbo into the engine intake, then the engine is not intercooled.

Rusty, Thanks for the explaination. I guess it would be safe to say that most charge air equipment on modern vehilces are intercooled.

Would fixed engines such as you work on be non-intercooled?

No, modern large stationary engines, be they spark gas, gas/diesel or straight diesel, are generally turbocharged and intercooled. This is for the same reaons as the automotive engines - we need to maximize horsepower, minimize fuel consumption (the main cost element) and minimize exhaust emissions.

Most of our intercoolers are air-to-liquid, however, that use a secondary (aka auxiliary) cooling loop that operates at a much lower temperature than the main engine cooling circuit and which cools the intercoolers, lube oil cooler and (if it's an engine/compressor unit) the compressor cylinders and piston rod packing. For packaging considerations, the automotive intercoolers are more generally air-to-air, although there are some air-to-liquid intercoolers out there as well.

Rusty, Thanks for the information. Any pictures available?

For some techno information on the Ford diesels, go over to Diesel Forum - TheDieselStop.com and look at the 6.0 form.

See my edited post above. Click on the attached image for a larger photo that shows the intercooler. This particular model of engine actually has two turbochargers and two intercoolers - one for each bank of power cylinders. Like the new Ford 6.7L diesel, most V-type industrial engines run the exhaust down the center of the Vee with the intake (air) manifolds on the outside of the Vee. This eases routing of the exhaust to the turbochargers and charge air to the aftercoolers and cylinder banks as is shown in the photo. The two large blue pipes carry intake air coming from the air filters through air silencers to the turbocharger inlets. The single silver pipe between them is carrying exhaust from the turbochargers to the exhaust silencer outside the building. The yellow pipes below the visible intercooler are carrying coolant to and from the intercooler.
