Ford 7.3L Gas Engine

[coobie]

Towed this explorer about 200 miles with my 20ft Pj bumper pull with my 2016 Ram 2500 6.4 hemi engine 3.73 gears and got a whopping 9.5 MPG,s driving 60-63 MPH highway driving.I am guessing the new ford 7.3 might get close to the same MPG,s towing.

I don't know either, that statement generally comes from people that hate Fords.. How about the cost of replacing one injector on a duramax?

The plug problem has been overblown by GM fan boys for years along with the exhaust manifold bolts snapping..

I’d get over that problem a lot faster than the motor being half under the cab and requiring the cabs to be pulled for any major repairs. Next problem on the era trucks I’m likely to buy the Chevy truck will turn a 10 foot tighter circle. My dually is 10 years older than my dads F350 SRW both trucks around 110k miles and mine drives better, turns tighter, and rides better.

Time will tell with this engine, just like anything else new. No one knows at this point if it is good or bad. They haven't even showed us the internals yet. They are taking a step back to old school tech with a push rod engine....nothing wrong with that either. :2cents:

Looks like Ford did their homework with this one.

I believe that only applies to F450 size and up... Which is why the V10 has still been offered in F450+ up to and including this year.

V10 is in lots of tow trucks, school buses, RV's... Many diehard fans. In my opinion this engine has big shoes to fill (based on my personal experience). But I'm definitely impressed and excited.

Now... If Ford would only offer an independent front axle setup as an option to work on that harsh ride!

Maybe something changed in the past couple years. I know nothing above 'half tons' had EPA ratings just 2 years ago.

If I recall, EPA doesn't test vehicles with a GVWR over 8500.

Will there be an EPA rating on this? I didn't think they tested engines in the HDs and up.

How does one compare a spark plug replacement to an injector replacement? That's like comparing apples to oranges, there is no comparison.

It's like comparing the miniscule amount of plug replacements on a Ford gasser was my point..

Hmmmm, have you driven a Super Duty lately? We have covered this already back a few months ago.. Same result..

The GM/Ford debate is like the Kubota/Deere debate, it's a good way to pass the time I guess on a hot day and that's about all it's good for...

People that are "bashing" this thing are crazy. Do they not understand how physics work and how torqy this thing is off idle. I'm a diesel guy and I must say, I'm impressed. If this motor gets mated to 4.30 gears it will pull anything just fine...even in a medium duty truck.

Exactly. 400 ft-lbs at 1500 rpm, and then a flat 'curve' all the way through 5500 rpm with only a 75 ft-lbs difference (475 max) through the range. It's gonna slot in nicely between the 6.2 and diesel.

Did you miss the era truck I’d drive part? I think they fixed that problem years ago. And no I’ve never driven a new Ford with 6 wheels. Doesn’t matter, I’ll never buy one.

I really thought it would break 500, on both numbers.

So for those interested, here is a discussion with the Ford guys putting together charts on HP vs Torque.
Yeah may not seem like much of an improvement for some. We all have a different baseline of what we expect for performance.
Ford did not spend years testing this engine for mediocre performance.
The target audience will be fleet owners, the RV'r, the F550/750 etc., all those like me that tow heavy but not often enough to justify a oil burner.
The local electric Co-Op uses the 6.2l for their service trucks. Low down time, maintenance and lower up front cost of the 6.7L.

7.3 L gas HP/TQ numbers out - Ford Truck Enthusiasts Forums

It was only three pages yesterday and heh see how quick it grew.
So enjoy for those in the market for a beefier engine/tranny (no not hollywood!) this may fill the ticket.
Also interested in MPGs but may have to wait until Dec. for some numbers after the new truck have a few thousand miles on them.
I'm so satisfied with my 6.2L and though its a 3.73 and not the 4.30, she works just fine.
I'm an old man I don't care if it pisses off people when I enter the roadway towing my Kioti and takes a few extra seconds to get to my 65 cruising speed....

Have they released the HP and Torque graphs yet? Why would they put 4.30 gears under it? Being that it will be mated with the 10 speed trans, there is no reason for high ratio gears.

Yes, follow the link I provided, more graph the Dow Jones...

See post #5 in this thread.

The torque curve looks like a diesel. It's amazing they can get that with a gas motor.

 

[nikerret]

I think they’re sandbagging. Give it two to three years and poof, the real numbers will come out.

 

[goeduck]

Pushrod and no boost. Interesting how designs go full circle.

 

[ruffdog]

I'm sure they are using some sort of variable cam/valve/lift to get better numbers. It is the age we are in now.

 

[Tractorable]

I’m sure Ford engineered in a good amount of “top cover” for when Chevy and Ram build the next “best in class” HP and torque numbers. I could see it easily hitting 500ft/lb+ numbers.
