Horsepower vs. Model Year
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.

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.

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.

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