RAM 6.4 Ike Gauntlet

If you don't have the same force applied to the road's surface for moving equal loads to an X velocity, the one supplying the lesser amoumt of force will always be behind! Got it?

Want to dispute this? Lets hear your wonderful explanation then. Mine is based on sound documented knowledge of the facts and backed by head to head testing results over and over. Your explanation, if you should choose to blowviate one, should be very interesting to say the least!

GM vehicles have always beaten Ford a Ram?

2017 3/4-Ton Work Truck Challenge

The only place the 6.0L beats the 6.4L is in the Ike which is only due to the 6.4L going into limp mode. If the 6.4L would not have gone into limp mode like it was programmed to, then I doubt the 6.0L would have had a quicker time.

As far as the difference in the type of SAE power methods, that is only for the diesels since it is Cummins who does that test for the 6.7L and not Ram. Cummins usees J1995 because the 6.7L is used in many different applications and Ram uses the same SAE J1349 certification method on the 6.4L that GM uses on the 6.0L as you can see in the link below.

Yep funny when the moved the truck forward (so they claimed) the sway went away. They are a joke and have been for awhile now. Shows how easy they can be bought.

Travelnutz,

I don't have to prove it wrong. It does take a certain amount of force to move the load. Weight is not the only load that is applied in the real world. It might be in a controlled environment like a proving ground but my proving ground is real world experience and pulling to different types, length, and loaded trailers that "weigh" the same is not going to net you the same results especially on a road that looks like it beats the truck to death. Trailer sway will slow you down by itself and they obviously had problems with that and blamed it on the coil suspension. I laugh at "Mr Truck" every time he opens his mouth about something.....LOL

There have been a few guys in the Ram forums who have experienced the limp mode(aka "feature") at much lower altitudes than the Ike.

IIRC, they said (summarizing) that it's a designed in software program when at high load, high rpm, high altitude (which rarely happens to 99.9% of the population), the engine kicks into to save the EGR systems or something like that. The Davis Dam grade test doesn't show this effect (stuck at 4k RPM in 2nd), so it appears they are being truthful. I never experienced it.

Hmm, very interesting!

One thing for sure - one should not use the 6.4 Hemi for kit plane applications :S :B

Exactly the opposite - look at Pickuptruck.com's dyno run, the 6.4 Hemi absolutely smokes the 6.0 GM:

GM: 276 hp, 311 lb-ft
RAM: 340 hp, 372 lb-ft

Your statement was somewhat true, back when Chrysler had horrible transmissions, like the 545RFE, or the 42LE in my old Intrepid. But modern 6.4 Hemi with 8 spd ZFs or manuals are dyno monsters.

You'll find most 6.4 Challengers putting down the same numbers as my LS7 Vette, even though mine was rated 20hp higher from factory.

Based on my reading, such as ib516 posting on towing in the Canadian rockies, people have been able to hold 2nd while towing at altitude. You can go 65+ in 2nd. Since I think this is the highest major road in the US (above 11K ft), this just may be a unique type test and Ram doesn't see a need to address it.

I think they need to address it, but maybe they are focused on getting an 8 speed transmission into the 6.4. That would be a great towing machine for a gasser.

I agree the programming/tune they use seems to **** out on the Ike Gauntlet, I never experienced that myself when towing at 8000' and less. Even when right to the floor (or close to it, high RPM anyway) for several minutes.

I even posted videos of my 6.4L Hemi towing as described in the previous paragraph. Some of you who have been around these forums a while have likely seen it. So, seems to be a non-issue for anyone who doesn't tow over the Eisenhower tunnel. I believe the "Davis Dam" towing test proves this as no one that tests the 6.4L Hemi there complains of this, and IIRC, the 6.4L Hemi was fastest on that grade which is what....7200'? Anyway, I was very happy with my truck when I had it.

I don't know that you can blame the gearing. At the top, it was high in the RPMs, but still slowing down. I think it is altitude and the steepness of the grade at the end that killed it. They used to be able to use time to quasi judge the trucks. But since the Eco-Boosts in the half tons, and the turbo diesels in the HD trucks, which have no problems staying at the speed limit, have come along, the altitude gets chopped out of the equation. So the moral of the story is that if you intend to climb steep hills to high elevation, get a truck that is NOT normally aspirated.

Well it looks like Nutz got his answer to the so called Ram inflated numbers and GM's so called "true numbers". Ram has always under rated their trucks unlike GM and Ford. Ram does not strip out their trucks so they can over inflate their EPA ratings unlike GM and Ford. Care to comment on that Nutz? I can post the links that show what items (it is long BTW) GM and Ford remove before they do their testing.

I have said over and over that all of the Big Three make great trucks. Unlike some of our resident fan boys I don't hate the other two. I have only had issues with Ford vehicles and yes it was a long time ago! But after getting burned three times (in a row mind you) they will never get another chance. Even if I didn't work for FCA.

I was actually offered a job as a Die Maker with Ford but turned it down mostly because we had just built a new home and I didn't want to drive 80 miles one way everyday seven days a week! Three months later I went to work for Chrysler in in Perrysburg.

OK, gotcha. Makes perfect sense now.
