Mike, can you clarify...

The over 10K GVWR version of the 6.2L is rated lower due to epa noise restrictions? This "implies" that the exhaust system is more restrictive, and possibly all else is the same... right? Would opening up the exhaust (free breathing kit) make more power?

This sounds like an aftermarket opportunity.

The Banks kit opened up my '94 460 quite nicely, I'm wondering if it's replacement, the 6.2L, is going to make slide-in camper hauling and towing more or less capable?

No, I'm not.

 

The exhaust is the same on SRW and DRW (I believe). You can get F350 (over 10k GVWR) with both SRW and DRW.

 

Sorry, but I can't comment about future products. As mentioned, 6.8 3V with 5R110 is available in F450.

 

1. Not that I am aware
2. I have not idea - sorry. Oh and if I did know, I couldn't tell you. Product strategies are closely guarded.

 

I think you're not understanding this right. The engine in the DRW trucks is the same engine. It makes the same amount of power and the same amount of torque.

When they certify the power output of the engine, for reasons Mike already mentioned they have to do it in a different manner. So the 385 HP @ 5,500 RPM engine in the SRW trucks becomes a 316 HP @4,179 RPMs for the DRW applications.

The SRW version also makes 316 HP @ 4,179 RPMs, but it's "rated" power is considered to be the HP peak which is at a higher RPM than that.

It's not that it makes less power. It's simply that the "rated" power is taken from a different RPM. For reasons I simply can't wrap my head around! It's STILL a 385 HP engine! Ford just can't call it that.

 

Hey Mike-V8Ford, thanks for stopping by here. My new 6.2 should be hitting the production line over the next coupla weeks according to my dealer. Can't wait! Can you offer insight into the updated programing that the engine computers got during the first month of production? And I will be switching to Mobil1 after sufficient breakin. Suggestions on time period for the switch.

Can you answer an age old question? Is the oil fill at the factory just some plain ol' conventional oil, or does it have some special blend for more rapid or improved break in?

 

I'm not aware of any calibration changes over the first month, so if it did happen, it can't have been anything major.

The 5W20 factory fill has no additional additives to help break in.

Ahead of a durabilty test on dyno, we run about 8 hours of break-in. In a vehicle, I would say about 1000 miles. First 500 driving normally without excessive engine speed, then 500 of higher speeds and loads.

Good luck with your new truck, and thanks for supporting Ford. Let us know your feedback on the new rig.

Mike.

 

Good explanation.

 

The problem with this explanation is going to be disseminating this information down to the dealership sales people.

A simple example of this is what happened to me this past weekend. My local dealer just got in a few 2011's and gave me a call to come on down, as he knows that I've been trying to order one of these since last year. I drive a gas engined SRW truck and during the test drive he mentions that the truck I have on order is going to be *considerably less powerful*, because I specified the "over 10K GVW option". WTB? I'm figuring that he just wants to steer me into the $7K upgrade for the diesel because he could not give me any sort of explanation for why the same engine would be less powerful in a heavier duty truck. I ended up canceling the order for now, because I want to actually drive the less powerful one before I give him a $600 non-refundable deposit. But now I find out here that it's really the same engine, same power output regardless of GVWR, just "rated" differently.

I sense that during the next few months chevy and Dodge marketing types are going to crucify Ford on gas engine power ratings, assuming that they can each make at least one more horse and one more foot pound.

I wonder if this has anything to do with the fiasco of a few years ago on the Mustang engines that were over-rated by Ford?

Sorry Mike, I'm not trying to kill the messenger here, don't take this personal!

I see what you're saying, Joseph! Myself and another FTE member discussed this exact same thing a couple months ago when the power numbers were released. Took us awhile to figure out that the reduced HP number was both at a lower RPM as well as at the exact same RPM the rated torque number was. So unless the engine had a rev limiter of 4,179 RPM peak HP lining up with peak torque was almost impossible.

But it's not just Ford that's affected by this. Chevy's 2011 6.0L V8 in SRW form is rated for 360 HP @ 5,400 RPM. Make it a DRW truck and it's now rated for 322 HP @ 4,400 RPM. What makes it interesting is how the torque peak is actually below the HP rating on the DRW chevies, which is at 4,200 RPMs.

So it appears that the HP rating is at the highest RPM they can make it comply with the EPA regulations. And because the engine's true torque peak is higher than that, the highest it can get without going over the 4,179 RPM HP peak would be the exact Torque rating at 4,179 RPMs, which is only 397 ft-lbs.

So it appears that the HP is rated as high as it can get while still meeting the noise(?!) requirements for trucks over 10,000 lbs GVWR, and the rated torque number can NOT be at a higher RPM.

Am I close, Mike?

 

What's also kind of neat is how Chevy's marketing types made an error on their comparison between the Ford, Chevy, and Dodge gas heavy duty pickups.

Go to Chevy's 2011 page...

2011 Silverado HD Truck | Pickup | Chevrolet.com

And click on the "specs comparison" tab.

Notice how Chevy compares their DRW(over 10,000) gas engine with it's reduced power "rating" with the SRW trucks from Ford and Dodge with their full peak power numbers.

This way it appears that the 322 HP 6.0L Chevy engine is compared with a 383 HP Hemi and 385 HP 6.2L Ford engine!

 

I did not read all the posts, my apologizes if this somewhat off topic question has been asked.

Is FoMoCo going to offer the 6.2L in an F150 besides the Raptor?

The reason I'm asking is...I'll buy one...when and if.

Since 1965, I've bought 7 new Ford trucks, 4 new Ford cars. Currently, my wife has a 2008 Edge SEL, I have a 2008 Fusion.

 

I'm pretty sure he cannot comment on such plans. But they really should, and need, to do exactly that. Just to become competitive. The 5.4 is pathetic compared to what is out there in half ton trucks, and this 6.2 just makes par.

 

I'm thinking that if they dropped the 6.2 into the half ton truck line that might cannibalize sales of the gas powered F-250. More likely is that in another couple of model years they're going to punch out the displacement to 7 or so litres, throw that in the Super Duties, then the 6.2 will find itself in the -150's. Of course, that all depends on what our neighbors across the street do.
