Performance charts

[rollinstone]

Can anyone direct me to Expedition performance charts? Torque is king when it comes to trailer towing and I'm curious about Expy torque output at different RPMs.

And while we're at it, I'd be happy to hear what Expy owners think about the towing capability of their trucks.

Idk about the 3ed gen but the first gen have power. I am in Florida everything is pretty level some hills but not that bad and I pull my 42 foot boat 9000 pounds to the keys 200 mile trip at 75 80 mph no proplom. I have the 5.4 with the deep transmission pan and with the 3.73 gear ration.

I have never seen any published dyno sheets on factory stock expeditions. Does not mean they do not exist. Just have seen none myself.

Supercharged 1st gen dyno sheet at rear wheels....



Unfortunately I did not lock it in 3rd gear in the tune so the dyno operator did not start feeding into it till after 3,000 rpm to keep it from down shifting. Fairly healthy when you consider 15-20% drivetrain losses at the rear wheels vs the crank.

I does tow quite well. Did so even stock...

I believe 80% of peak torque is available from 2,000 rpms on if I am not mistaken, even more when running E85.
