Same motor diff HP ratings????
I got a dumb question. When for came out with the 6.2L V8 for the F250 it was rated for 385hp and 405 ft-lbs torque. I just saw that the 6.2L for the upcoming F150 will be 411 hp and 434ft-lbs torque. I understand that differences in cams can up hp ratings for the same displacement motors, but why would you want more hp and torque in a F150 than you would in a F250? I see that chevy has done the same also, their 6.2L they offer in the Silverado 1500 has way higher hp and torque numbers than the 6.0L they offer in the 3/4ton.
I guess it just seems a little weird to me that your 3/4 ton truck that is meant to tow more has lower hp and torque numbers than your 1/2 ton

it could be possible that they possibly have tuned down these motors because they are going in a bigger truck and are probably going to be doing more "work" with them. Most likely they have lowered the power on them to extend the lifetime of the motor when being used in a "working" condition such as pulling a trailer. Not that an f150 wont be capable of pulling but on a 3/4 ton truck they might want to tone the motor down to extend the useable life out of it.

Thats really what im getting at with my question. I want to know what the HP and Torque curves for these two motors are so that i can see what percentage of hp and torque you can get out of these motors at 2,000rpm. How much hp they make at 5000rpms is useless info to me because i will never drive or pull a trailer at that rpm.

Most likely they tuned it up a bit to beat anything Dodge and Chevy could offer for 2011. Might see the higher numbers on the heavy haulers next year. They did that with the 6.7 diesel. Chevy came out a bit higher with their 2011 d-max so Ford came out with a hotter tune to get back on top of Chevy. Ford is placing the hotter tune on the 2011 6.7 they are building now and offering the hotter tune to everyone that already bought the new diesel for a free upgrade.

So basically the 6.2 in the superduty will get a higher percentage of its 385hp and 405ft-lbs of torque at lower rpms and the F150 will have higher top end hp but wont get the higher percentage of hp and torque at as low of rpms?
