I just test drove 2012 6.2l lariet f250 with FX4 with 13000 miles on it.
It was traded in for a 2012 diesel for lack of power. The motor has no bottom end torque unless you have your foot in at, have tach at 4500 rpm. This will be true for all new motors in any vehicle (any manufactor) as the compression is so low to make emmision standards. You need compression for HP or delay timing and allow for air (turbo chargers) to fill cylinders up after TDC to get power. The only way to do this is high RPM for the turbo chargers to work. I have changed my thinking and will be buying a diesel either ford or chev.

yeah the 6.2 in the f250 makes very little sense to me.

I think ford could make a ecoboost that could almost replace the diesel in superdutys , how about a 4.5l v6 with 700lbs of torque off idle, but to the op I agree with you , I've tested the6.2 in the super and asnt impressed, but I think that's on purpose to sell the6.7

Your seat of the pants evaluation lines up with the facts. When you build an engine with short stroke, big bore, big heads (big valves, big intake ports, big exhaust ports), big intake manifold pipes, big cams (long duration, much overlap), then what you just built is a rev motor and not a torque motor. Lots of advertised power at 4500 RPM, and lots of fun after it gets up on the pipes, but not much grunt down low.

Add to this the fact that the PCM *knows* what the power curve of the engine is. So if you are towing a big trailer up I-70 to Eisenhower Tunnel, the PCM is going to respond by choosing a gear that makes the engine scream at 5000+ RPM for miles on end!!! Sounds beautiful like Sunday at Daytona, but really how much sustained high-load high-RPM torture do you want to submit your pocketbook to?!?

Thanks for the feedback , I enjoyed it. I logged over 950k in a diesel Semi and only way to make it to top of any Mtn Range, down shift keep rpm high in any type of
weather to keep pulling power equal and not spinout. I never seen yet a turbo yet keep maxium boost but slowly die with time and lose the boost. As a driver you was
unaware of the power slowly going away until a new turbo was installed.

Not too Boast, I owned my Auto Repair, Became ASE Master Mechanic, Was a Computer Tech for 30 yrs Certified Micosoft MCSE in NT 4.0. I am semi retirered and
looking at the specs of a 2011 6.7 Ford Diesel. I will deactivate the DPF. The Diesel egr problems can only be reduced by going electronic activation as they did with automotive gas engines in the 90's with slow egrs. This ego boost is sicking , just use
nitro if you have have that much power.

I hope that I'm not the only one here concerned about this, my question; how is Ford going to respond to the new GM 6.2l and how long will it take? The torque curve on this is better than I first thought and is impressive. 420 hp 460 lb-ft I also found that red line is 6300 RPM.

Z7What

Low compression??????

My 5.0L is 10.5:1 IIRC

so what would be a good swap in my 06 f150? Supercharged 6.2?

For what that would cost, you'd be better off just trading in for a newer truck with a 6.2 already in it.
