Can anyone point me to a reference that shows the PSD horsepower ratings by model year. All these years I've been thinking my '96 was 195hp, but today I find a sticker on the valve cover that says it's 215.

 

From 94.5-96, they were all rated 215hp at the flywheel. The '97's built for California had different injectors, so they were rated at 225hp. Starting in '99 they were rated at 235hp. These are all flywheel numbers. Dyno numbers would be lower, obviously.

 

Thx, not sure where I got the 195hp number...

 

It could have been a dyno number someone reported. My truck dyno'd 195 when stock, so that might have been it.

 

I think all the 1997 trucks were rated for 225 HP. My truck is not a California truck (has single shot injectors) and it is rated for 225 HP. Also, at some point, I can't remember what year, the autos were raised to 250 HP and the manuals to 275 HP above the 235 HP rating.

 

i think the 250 hp rating was around the 00 year, but i might be wrong

 

My '97, which is a Texas truck, has a rating of 215 on the valve cover.

 

The 225 HP rating might have been only for the 5-speed and not the auto. Mine is a 5-speed and has 225 HP on the valve cover. Can anyone confirm this?

 

MY sticker has come off or something I dont see it anywhere. From what I understand, they were rated at 220 or 215 until 01 when they were upgraded to 250 for the auto and 275 for the standard. I have a 5 speed and a 4.10 rear. Even bone stock the thing ran like a scalded ape so much power.

 

I've never seen a "scalded ape" run. I wonder what this would look like

 

My 1997 is 225 and in 1999 they upped it to 235. In 01 they were upping the power from 235.

 

So from 97 to 99 only 10 hp were added due to the intercooler? That seems low.

 

My company has two 97 Super Dutys with the Power Stroke and Auto tranny and the valve cover says 225 Bhp.

 

There's a common misconception about intercoolers. They don't add power. They're often on powerful trucks, but they aren't what makes the power. The SuperDuty's power was increased over the original body style trucks by the addition of bigger injectors. As you increase the amount of fuel, you increase two things: power and heat. The intercooler was added to offset the increase in heat, but does nothing to increase power. True, the air entering the turbo is cooler, so some think that, in itself, will increase power. However, the increased area that needs to be pressurized due to the presence of an intercooler, results in turbo lag, which delays the increase in boost, which delays fuel, etc.
The addition of the intercooler on SuperDuty's is also the reason they went to a smaller turbine housing, to offset the turbo lag induced by the intercooler. If a stock SuperDuty seems to accelerate more quickly than a stock "original body style" truck, it's the injectors and turbo doing it, not the intercooler.

 

Yeah....mine is an auto with 215....
