2015 Lincoln EcoBoost vs the Ike Gauntlet

The Lincoln waxed the GM on the Ike whether anybody wants to admit it or not.

Here is the math to show how this works out.

The GMC comes with a 420 HP NA engine. The standard formula for altitude lose is 3%/ 1000 feet. The Ike tunnel is 11,000 up. I don't know what the climb is from A to B is but lets just say it's an average of 10,000 for round figures. The math says the 6.2 WILL lose over 120 HP at that altitude! That brings the potent 6.2 down to an impotent 300 HP. That's why the Cheby was shifting over and over and over again. It was trying to keep the engine in the power band because it needed all of that 300 HP it had.

Now for the twin snail engine.

The EB is reported to put out 380 HP in this vehicle. Since most turbo engines have extra air to put out they lose very little HP if any. So as anybody can see, the EB is going to have a 80+ HP advantage.

Another advantage is this engine can pump a lot of air at a low RPM giving it a wide flat curve.

Another thing to think about is the weather. The 6.2 would have a very hard time pulling up that mountain if it was 90 degrees out. Air density would have been way down. The GMC really got an advantage when towing in this type of weather.

While I follow your logic I fail to see how the engine that was down on hp could accelerate and the one that wasn't couldn't, and how you think the EB waxed the 6.2. In summer it may have been different, but in this test the 6.2 was not waxed, as it had power to spare when the EB didn't.

If the EB had more gears it would have been shifting too. 65mph in 2nd is above redline, therefore a downshift wasn't going to happen until the vehicle slowed a bit. It had enough hp to hold, but not to accelerate. The 6.2 was accelerating.

Does anyone know the WG specs on the EB? I would be curious how much boost it runs, and how much it has to spare. Mid rpm range is the hardest range to make peak power at elevation as the turbo isn't always running against the WG at WOT like it would be at rated rpm.

I don't think they mentioned GVW, so I wonder how close they were?? Shipping weight is close, but options can add quite a bit.


Math is one thing, actual results are another.

Gearing is huge when your getting power to the wheels. We know how much power the 6.2 loses at elevation, but the amount lost by the EB is an unknown. If the EB didn't lose any, unlikely, then Ford needs to work on gearing.
