81mph speed limit.

[sredish]

F450s and F550s have an 81mph speed limit in place.

[_CH_]

bullshit! WTF is that?

[heinzboy]

Is it becuase of the tire speed ratings?

[banksforddiesel99]

i bet we can get around that with tuning, huh dougy?!?

[diesel71]

uhhhhaaa that's another reason i went with a f-350

[PSDPlayer]

It has 4.88s dumbasses. Think about the fucking revs above 81mph. Do you want to be running down the highway at 4,000 rpm? They also put in a speed limiter for jack asses that think you should pull 45,000lbs with a 450 but don't realize they can't stop.

Sir that post was after midnight. I was about to go to sleep on the wrong side of the bed. I just wanted to make the point of thinkin about what the truck was deisgned to do before we started trying to make a new 6.4L rev out like a 4.6L

[_CH_]

hey now.... i liked my 4.6L it was a good engine in a bad azz truck :D

[PSDPlayer]

Im not saying there is anything wrong with a 4.6L I'm saying if you rev a 6.4L like a 4.6L then let me know so I can be as far away from that explosion as possible.
