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

Typical GM owner.

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.
