How Many Horse Does A New 5.4l Stock Put Out?
 

I have a new 06 FX4 with a 5.4L and I will be installing the Edge Evolution Programmer in the morning. Curious as to how many horsepower this motor would be producing before this mod is done. I have upgraded from the factory exhaust and added the K&N 77 series intake. Any ideas as to factory out put?

300HP on the dot...FWHP

300 HP at the flywheel. ~210 at the wheels.

Wow, those are pretty ridiculously low numbers at the wheels. I'd like to know what the 1997 4.6 has at the wheels if it says it only has 210 HP. Not sure whether that's at the wheels or flywheel. Let me know if any of you guys know.

^Im think its in the 165 area average for the 4.6....Mike T. told me at one time but I cant remember exactley what he said, somwhere around there.

thats not too bad for a rear wheel drive vehicle if you think about it. ~30% for the 5.4 and ~22% for the 4.6. I have seen it to where older rwd vehicles would lose 35-40% of their horsepower. Most fwd vehicles now a days still lose ~20%. VW has been the only one that I have seen to advertise what their vehicles put out at the wheels(the new rabbit is advertised @150hp and dynos are coming in at 148, 151...)

Hahaha, Rabbits on a dyno...makes me chuckle a little :lol:
