Anyone have a 6L PSD power curve ? (Was PSD Power Curve) - Diesel Forum

MackE7 · 06-02-2005, 02:29 PM

Does anyone know where I can find a torque and HP curve for the PSD ?

I've got a brochure, but all it states is maximum torque and maximum power.

It there a curve on the Internet somewhere ?

Thanks.

here is one.

Thanks, but I want engine HP, as rated by the factory.

Here's the one from the '02 brochure. Sorry my scanner is not better.

The red scale on the left (net torque) is 300 thru 550 lb/ft in increments of 50. The blue scale on the right (HP) is zero thru 250 HP in increments of 50. The RPM scale on the bottom is 500 thru 3,000 in increments of 500.

I meant the 6L PSD... is it still called a PSD ?

I'd like to see a power and torque curve for the new 6L engines. Has Ford ever published one ? I can't find any reference to one.

I got a brochure today and there isn't one in it and my sales guy can't seem to find one either. But then he isn't very knowledgable about these trucks. He thought the automatic was a 6 speed.

It is.

In late 2003 there was a HP and TQ graph in the ford literature.

I didn't save it. [img]/ubbthreads/images/graemlins/frown.gif[/img]

Isn't it a 5 speed automatic ? Why do you say it is a 6 speed automatic ?

The brochure says it is a 5 speed automatic. Am I missing something ?

I found one here. http://dan.prxy.org/Truck/Engine/Engine_info_FRAME.html

Thanks.

The TorqShift is advertised as being a 5 speed automatic, when actually it has six forward speeds. On cold engine operation (below 0 degrees) the overdrive clutch is engaged in third gear for a ratio of 1.09 : 1. The transmission will shift directly to sixth from fourth and fifth is skipped. On a warm engine the shift pattern would be 1st, 2nd, 3rd, 5th (direct drive), 6th.

That wasn't what the salesman meant. He had the auto and the stick transmissions confused.

Furthermore, it might have 6 gears, but it only ever shifts 5 going from stop to highway speed. Thus it is really a 5 speed transmission.

Some truck transmissions have ratio overlap and they aren't counted. Some 13 speeds are like that.

I think "5 Speed" is the most correct term to describe this trans because thats what Ford calls it,but.

It is really a 3 speed with an OD. The OD can be applied to any one of the three forward speeds by programming. The normal programming applies OD to first gear to get your second speed and to third gear to get your fifth speed.

I know. I was just messing with you. [img]/ubbthreads/images/graemlins/zombie.gif[/img]

What about reverse??? Ok, I'll drop it.

I'm just jealous of the 6 speed guys. [img]/ubbthreads/images/graemlins/crazy.gif[/img]

go to the sunrisefordfleet.com site and check the download area - there an engine brochure that has one
