And the HP Wars Begin

[timswi]

Yeah, the 6.2's and 6.5's were detroit diesels. GM owned Detroit Diesel for a long time, but they sold them off several years ago. I have been doing a lot of research on the engines so I can fix up my wife's old Step-Side. There is a nasty rumor floating around that the engines are gas conversions, which they are not. The old 5.7L diesels were supposed to be the "gas conversion" motors, but I think that too is a fallacy. I think they used some basic common measurements for the 5.7L diesel as the 5.7gas, but it is supposed to be a completely different block. GM just made it too weak in the head area etc. and it blew a lot of gaskets.

Agreed..I used to work on a 5.7 diesel Caddie for a guy I know. Not a bad car at all, ran good, got great gas mileage. He didn't treat it like a gas engine. He drove it like a human being and got around 225k out of it before he traded it. Only mechanical stuff was the water pump and alternator.

I was a little loud for a Cadillac.

The ex-fiance's parents had a Park Avenue with a 5.7 diesel and they ran that thing for years without doing anything to it beyond general maintenance.

The QSB4.5 is capable of 230hp when tuned to the same power per cylinder as the QSB6.7
America just has to get used to the 4 cylinder sound.... Some folks love the sound of those noisy Detroit 2 stroke Jimmies, so there will be some that like a QSB4.5 as well...

It would be only a small risk for them to put the configuration of the Dodge 6.7 into the QSB4.5 industrial engine.

However i think their idea is that the heavy duty market would want the power of the QSB6.7 and the commuter market would want the refinement of a V8 engine... Trying a 4.5 I4 in the 1500 would probably be competition for the 6.7 (which means investment in two engines, for the profit of one) while a 5.0 V8 would not be any competition for their existing 6.7 but tap into a whole new market.

I said it was coming. GM will be left behind at the end of the day using a engine that is at its limits of both HP/TQ but also technology and room to grow. My prediction is we will see GM with a whole new engine in the next 3 years to compete with Ford and Dodge and the newer designs with room to grow of the life of the engine.

We were at the Bristol nascar race and guess what Ford had out side in their tent... the NEW Scorpion engine in a Ford F250

What tabloid do you get your info from? Lets first see if this Scorpoin will even hold together, after all, it is designed by Ford. Did you forget about all the changes they wanted done to the 6.0, and what happened to them only and not Navistar?? And the 6.4 was not muc better.

Face it, the DMAX is the real deal, and will remain on top, in power and reliabiulity.

Typical Ford owner.

I agree with this...let's wait a few years until we see that the engine is as reliable as the Dmax. The Dmax has proven itself to be a great and reliable engine.

Afterall, at what point does more horsepower just become pointless? I think the Dmax still has a little bit left anyways.

The Scorpion has a lot of proving to do I will agree. The hope is Ford did the R&D necessary to hit a ball out of the park. If its anything like their class leading trucks it should be a winner.

When has Dmax been the real deal? I agree its a decent engine but that is where it stops. They have problems just like any other. Trust me, I had one and my neighbor has one sitting in his drive with bad injectors right now. The rest of the truck is just not up to par. They are making improvements to keep it in line with Ford but that IFS is a joke and you know it.

Lets face it the Dmax is at the end of its rope. Time will tell if Isuzu can come up with another winner for them.

The new Dmax isn't exactly "proven" either.

Should we discuss the track record of GM diesels. LOL

Chris,

I have posted with you on this forum for many some number of years now and have found your logic and insight on the mark more often than not. In this case, I think you may be a bit delusional. While I still think Ford has the best chassis and suspension on the market, it is not light years ahead of GM. The GM powertrain is better including the transmission and rear differential. I think we all could come up with a person or two who owned a given brand who had trouble, but I will say my GMC tows great and right up to its limit. It has never given me a spot of trouble and the refinement it has for a 3/4 ton truck is astounding. I just do not see the the GM trucks are not up to snuff as you suggest. Having had both brands within the past three years I feel I have some ground to stand on and personal use and experience not shared by many. I enjoyed my KR 2008 6.4L and also feel Ford did a good job developing its new heavy duty truck. I think it will be a good one; but that said, Ford will have to develop product that is fantastic to make me go back as the GM product right now is simply nicer--aside from those specifics I have mentioned in previous posts. From me, that is saying something. As for the Duramax being at the end of its run, the only thing I see terminating the Duramax run is the silly and overbearing emissions laws on diesels. These rules are going to make owning any diesel an expensive proposition. I am sure that GM will update the Duramax, as they currently are, but to say that an engine capable of producing 600-700 hp fairly easily and nearly 1000 lb.ft. of torque in race or pulling applications and pumping out in some cases greater than 100 psi boost is at the end of its rope is a bit erroneous. None of these engines and certainly not the Duramax are anywhere close to their limit capabilities.

Strongly disagree with you on that one. I have driven them all, Ford P-Stroke, Cummins, and Chevy.

We had a 6.0 P-Stroke that was actually used to perform work, unlike most diesel trucks on the road. Towed Case 580K back-hoes, multiple gooseneck trailers to/from job-sites. Pulled stuck tractors and rigs out. In general using these trucks for what they were designed for. Had trouble with them all too.

In mine and my families experience the D-Max has performed very well. Diesels and bad injectors are just a part of the game. Last time I checked nobody made an injector that didn't eventually need replacement, including Ford.

We got rid of the 6.0, but replaced it with the 6.4 because that was the only engine available for the equipment we need. You know, the one Ford bragged about so much they are already replacing it!! Jury's still out on this one, but I still like the Dmax better.

Scorpion has yet to sell a single unit, let's wait before we pass judgement.

I can not wait to see how they stack up in the real world say pulling a 14K dump trailer loaded then a 16,000# GN or 5th Wheel trailer. I would also like to see stopping distances with both rigs and fuel economy of both on say a 200 mile trip including both stop and go traffic, grade climbs, and highway driving at 70mph. There tranny, rear axle, tire size, ect can change all the numbers.

All I can say about this is, if that powerful engine is protected by an eggshell what good is it? I offer the following pictures as evidence. The first, is a picture of the 2005 Chevy 2500, (US government truck,) that rear ended me in upstate NY. It was completely totaled. The next picture is of the rear end of my truck, where he hit me. All the police, and people who saw this were astounded, as was I. My truck is a 2004 F250 crew cab super duty,short bed, with V10. I know, "they make em stronger now," I don't believe a word of it. Of course, Uncle Saw has yet to even look at the damage to my truck, let alone settle up, it's been two months. I bet if I had hit the Government truck, My wages would be garnished, and my tax return confiscated by now.

Uhh, not to rain on your parade, but it is pretty obviose that the bumper on truck that hit you, for the most part went under the rear bumper on your F 250. The radiator support, hood and fenders on the GM beared the brunt of the impact with your much stouter rear bumper and hitch. About 10 years ago, a woman in a mid 90's 1500 2wd chevy rearende my 99 F350 4x4 dualy. The results were very similar to what you posted. My false sense of security was short lived, as about a month later a coworker rearended a dakota with his New 2000 F250 a block away from work. his Ford looked alot like the chevy in your picture afterwards.

As for the insurance, I would place a call to your states insurance commisioner.

Unfortunately most people who buy one will only be able to tell you about how many sacks of groceries it was able to haul.
They won't be able to tell you anything about how it tows or stops under a load.

I wish the that fuel mileage would be a greater concern than this foolishness. If you need a medium duty truck, get one. Stuffing a lot of motor in a 3/4 or 1 ton truck does not make it a MD.

Another reason to stick to the tried and proven Cummins diesel RAM with no Diesel Exhaust Fluid required and 350hp/650lb.ft. :thumbsup:

While I agree the Cummins is the class leader it will be a hard sell with GM and Ford making 50 more HP and 150 FT LB more torque and tow ratings being as much as 5,000# more. Dodge will have to follow to sell trucks. Remember many who buy them want bragging rights, thats why they sell the way they do.

Anyway I am glad Ford is back on top where they belong. Cant let them folks in Washington win the race.
