Ford did OK with their boosted offerings in the gas arena (SVT stuff, SVO Mustang, Turbo Tbird, etc) and their diesel offerings to the 7.3 have been rock solid.

The problems IMO are of the user nature- the owner figures that if factory boost is good, more MUST be better. Boost is a great drug, and its relatively easy (especially on a turbo) to boost an engine to destruction. I'll bet the Eco-Boost owner put some sort of restriction in the wastegate circuit to increase the boost without compensating for additional fuel.

BTW, the same calamity can (and did) happen to GM products, as well as the old Shelby Omni GLHS, Chargers, Spirit R/Ts and turbo minivans.

Wow, that's a bold statement especially on a Ram forum.

Seriously though, I'd really like to see the numbers on this, because I find it hard to accept that, at say 1500-2000 rpm (prime initial load moving rpms) the turbo has spooled up enough for a gas V6 to out-torque a Hemi V8 (a diesel, yes - a gas V6, no). If it does make it's power down low, then it's got to be out of steam for the higher rpms. Remember, I'm also a CTD owner who tows +10,000lbs so I know about boost, torque and rpm ranges. For example, my 03 Hemi would smoke the tires from a dead idle when flatfooted, then hook after a couple of truck lengths. If I flatfoot my Cummins from a dead idle (same size tires and gearing), it rolls out for about a truck length or so before the boost comes in and then it destroys the tires (my 2011 Hemi has different size tires and gearing so it's not an apples to apples comparison). The Hemi then makes more torque again from 3100-5600 rpm since the CTD redlines at 3100 rpm and therefore makes no torque in that range.

LOL well I'm just being honest....everyone knows I'd take the ram over the ford (I did), and I'd take the hemi over the ecoboost because I think it's more reliable, and they are near equal power wise and torque wise.

I've looked it up before and can't comment much below 2,000 rpm because almost no dyno's are recorded at that low of rpm, but if I remember correctly it made peak torque at like 2,200 rpm (like 420lb ft) and it was over 400 lb ft from like 1,800 rpm to 5,500 rpm. Pretty impressive, and it is more than the hemi at any rpm (don't know about below 1,800 rpm, but I'd bet it's more, or about equal at the least). I understand and agree what you are saying about spooling the turbos, but just say it doesn't make good torque until 1,500 rpm, and the hemi does.....if there's a 1,500 to 2,000 rpm stall converter, it doesn't matter anyway.

You can google and find dyno's on it.

Sounds like my GNs of old.......stab the gas, start to move, then the boost hits and the 85mph speedo pegs to the right and massive white smoke erupts as the tires liquefy.......good fun it was! Thank God 245/60R15 tires were cheap!

I do like the Ecoboost- almost bought one. The boosted V6 would have been a great toy to play with, but the overall package of the Ram (interior comfort, ergonomics, ride quality, NVH index (noise vibration harshness), pricing, and dealer experience = 2011 Ram 1500.

I just reread that post and I'd find it very hard to believe that the hemi produces more torque at any rpm vs the CTD. HP yes, but not torque. Torque is not dependent on rpm, only hp is.

The thing thats crazy about the whole thing to me is this...
Ford brings the 5.0 back as their new motor to replace the 5.4 (which I think is a good thing), and they allow the 6.2liter in the F150 for the owners that want the big block under the hood. THEN they roll out this eco-boost V-6 thats pretty much cuts the feet out from under the NEW 5.0 . Can you imagine how good they'd be selling if they'd made a dual turbo'd 5.0... Like I said before, you keep your eco-boost, I'll keep my dignity...
