BS. 500 rwhp? from a duramax? I don't believe that for a second.


If the chevy or dodge were a superior product, I would own one.

 

jeeeze, Customz, I was gonna' let him get away with that since he doesn't even have a clue as to the changes between an LB7 and an LLY (egr valve only, give me a break, how about reworking the whole head for the new injection system??!).

Heck, he's juz hangin' out over hear to stir things up a bit anyway...

 

well, I am no rookie. I could go into tons of detail on all of the little changes they made between the LLY and the LB7, but the only man change to was to meet emisions. (EGR) Ya the heads changed some, and different injectors, a VVT turbo, higher fuel line pressures, lower compression pistons, and the list goes on. (including hp and torque ratings) But for the intent of my post was the main difference being EGR. Sorry, my goal is not to make myself look stupid.

If you doubt me on the 500rwhp tune, then check out diesel place Competition Forum. We have a guy running close to 700rwhp (683 and 1306 on #2) with only a turbo and twin CP3.

On Edit: If you doubt me, when you order EFI Live from mcratracing.com, he has been giving a free 500rwhp tune. So doubt away, but the duramax makes tons of power extremely cheap. Well after you buy an aftermarket trans kit.

 

I will continue to doubt away cuz there must be other mods to lower egts with those #s (or TT like you so slyly snuck in).

Either way the duramax is a fellow V8 bretheren which shows that two small truck manufacturers can't be that far off base (ford and cheb).

Read about the v6, v8 cummins due for the future...which brings me back to the OP question?

Why did ford go with the v block?

 

Well I'm going to make one more comment here and much like before you probablly wont like it. But think of this from a marketing point of veiw. If someone new to diesels walks in and says they want one ford can just say they offer a V8 and dodge only runs some 6 cylinder. Well to the foolish and ignorant the mind would automatically jump to the primal urg for more power so V8=good.

Another comment here. Now I'm thinking once you see the dodge cummins contrat expire ford may jump at the chance. I mean ford dealers have been saying for years that ford owns cummins. (BS) But in 2009 or 2010 when the contract runs out you may see some changes.

 

You are right, marketing is what it is all about. The public is just a bunch of sheep to industry and politicians. And we wonder why things never change... I know a lot of people who would never look at another truck if ford get the cummins contract and actually used it.

 

sorry, no twins turbos, no twin CP3's, no aftermarket turbo, no big injectors, no cam, no air intake, no exhausts mods. most use a secondary pusher pump, air intake, and exhaust mods, but even that is not necessary to make an easy 500rwhp. There are a few minor electronics that need to be modified to keep from setting codes, but otherwise 500rwhp on a dmax is all done via my computer to a truck. Pretty cool and pretty simple.

I am not saying that I would pull a camper up a mountain grade with a completely stock truck with a 500rwhp tune, but on the dyno and on the sled, it can be done.

BTW, the duramax manifolds can be seen glowing red at the pulls with no apparent harm to the "weak aluminum heads".

The top dmax is now at 813rwhp.

The only way to really know the competition is to read their forums, maybe you ought to do some research.

 

ok, so i just read nine pages of why ford went with the V-block, instead of the I-block. i truly only read maybe 3 or 4 threads actually concerning this matter, the rest is a bunch of bs. where did trains come into play? i do agree with, what alot of people have said, as far as, if your looking in the diesel direction, u want more bottom end torque. i do not agree with the whole part about no being able to fit enough gears such as big rigs, the new lexus ls,the self parking car, has an eight speed tranny in a car, double the size of the vehicle, and we cant fit more than six gears in a truck? anyways, i think what we might need to look at is when did ford and powerstroke sign the contract, and the same with dodge, or gm. this could lead us to the answer. does anyone know when ford signed o with powerstroke? o and by btw, i am 17.

I think you will find that ford went with the V8 as it would fit in the frame of the existing F series of trucks with little or not change which made engine selection easy you just picked the engine you wanted and put it in the truck.
Also if you check things out Dodge had all kinds of things to do to there truck to get the cummins in.

 

ok, but what i am asking is, WHEN did ford decide to go with powerstroke?

 

I beleive ford went with the powerstroke in 93 or 94, after using the origional IDI's.

 

Ford power stroke came about in 94 when they added the turbo to the 7.3. They first used the engine as a 6.9 in 83. then it went to 7.3 and then they added the turbo in 94. Many upgrades along the way. But the base engine was the same since 83.

 

The turbo and injection system were the biggest changes i beleive.

 

Yes...injectors like many other things evolved. Each year things always change a bit. HOPEFULLY for the better. I loved the 7.3 without the turbo..NO power...lol...but the damn things would run for a million miles...lol

 

Ain't that the truth.
