I know everyone but me knows but what is the horsepower rating for a 2000 F350 with stock 7.3 power stroke.

 

235 hp and then the later years they had 250 for the automatic and 275 for a manual tranny, but i dont know what the tranny would have to do with hp.

 

Thanks I had a idea but wasn't sure.

 

are those numbers rwhp?

 

Those are the Rated power IH gives the motor (Sticker on Pass side valve cover)

 

according to my brouchere for my 2000 an automatic had 250hp(auto), and 275hp(manual). however the 2002 brouchere states 325hp. So when I had troubles getting my truck started in cold weather, I had them reflash the pcm to the latest 7.3 sitting.

 

I too wondered if it was RW or flywheel but I believe it is flywheel. The standards being rated higher almost leads me to believe it would be RWHP but I think it has more to do with what the trannies can handle, or what Ford wanted them to handle.

 

That what it says on my passenger side valve cover

Yes Tom, we know about the rating numbers. Curiously, nobody has a definitive answer as to the difference between the autos and sticks. Also, this must obviously be controlled by programming because they are otherwise identical.

I believe these are flywheel numbers controlled by the PCM and that translates into some lame numbers at the rear wheels. Thank goodness for copious amounts of torque though. We all seem to forget those numbers.

Now those low HP numbers work well for Ford for warranty purposes. International keeps theirs low for longevity. That is why tuners and chips can really wake these things up because a lot is left on the table.

There was a saying from long ago, the dog that poops fast does not poop for long. Things were simpler then but it still applies.

 

I could have swore my hp was 265 on a stock 250. I will have to look at the manual.

 

a guy here recently dynoed his truck, bone stock before any mods. I believe had cranked out 170ish HP, and 410ish torque. I'm going to look for that thread.

Last spring, i dynoed my truck on the stock chip setting, and that includes all of my mods except the ATS housing and the fuel system. 208hp and 430tq.

 

all the hp numbers givin from the factory are at the crank not the wheel, if it were at the wheel then ford would have different power ratings for every different cab/drive/wheel and tire size combo that they offer (just wouldn't be economical for the company to do this). Now the 99's (im pretty sure the early 99 as well) thru the early 01's in standard have 235hp, the 99's thru 00's in automatic have 235hp as well. Around october of 2000 (part of the way thru the 01 builds) ford changed the standards to 275hp and all of the engines made past that point had the pmr's instead of the forged rods (thats both standard trucks and autos). all the 01 autos had 250hp and im fairly sure that they didn't get the boost up to 275hp until 03 but it could have been 02.

 

Looked at the valve cover on my 2000 350 dually 7.3 auto and it said 235 hp

 

This is what i have been thinking about because if the only differenece is the programing then can't i just either get my pcm reflashed or get a pcm out of a late 01-early 03 truck with a standard and gain an extra 40hp and 30ft/lbs of torque?

 

Another reason for the difference in the factor ratings of the autos vs manuals is the manuals just put more power to the ground. If you dyno an auto and a manual all w/ the same mods and all else being equal, the manual will dyno higher. For example, the typical truck like mine w/ intake/exhaust/dp-tuner will put down around 300 hp, but w/ a manual, around 330 hp.
