just wondered what the HP and torque of my 2003 f-150 scab 4x4 5.4 would be? had a little discussion with a friend at work and just wanted to get my facts straight. anybody know where there is engine comparisons on this?

 

HI!... 260H.P/350FT/LBS of TQ. Those are the factory FLYWHEEL #'s.

 

Its 260 Hp And 340 TQ.

 

I thought it was 260HP and 325 ft/lbs of TQ.

 

looks like the 5.4L torque is ascending...

can i get a 315ft/lbs?

 

Wouldn't that be 'descending'?

 

anyone have a link to an actual dyno chart? I googled around and haven't been able to find one

 

Ascending=up
Descending=down
Ive always heard 325

 

The 2003 5.4 made 260hp and 350tq, as for your dyno graphs try www.dynoperformance.com they might have it.

 

yeh u can look at it either way:-p from my post up or starting from top to bottom... meaning decending lol

 

HI!... Sorry guys but the "99" - "03" 5.4 2 valves were rated at 260H.P and 350FT/LBS of TQ at the flywheel.

 

yeh under optimal air temp and air density conditions... in a dyno chamber.... but yeh factory stated numbers are as u say

 

HI!... I KNOW.............
