just saw this on another forum. http://www.pickuptrucks.com/html/2010/gm/silverado/duramax/2010-chevrolet-silverado-1500-4-5-liter-duramax-diesel-spied.html

Thanks for the link. It's cool to know that they have some of these driving around right now as testers. I do find it funny that they try to cover it up with the 2500 hd badges.

Cool, thanks for the link........

I sure hope the 4.5 will be available in the RC SWB 2wd :)

Good info! Thanks

I liked the last line,

The 2010 Dodge Ram 1500 is expected to offer both V-6 and V-8 diesels built by Cummins.

That is a perspective issue. Those inline engines tend to last forever, while the V configurations wear out much sooner. If you are selling engines, it's much better to have the repeat customer!!!

the automotive V diesel engines were built as light-duty and Inline equipment diesels were designed as medium duty, lots of difference. the cummins engines you will find SAE continuos HP/Torque rating, basically load up engine for somany hours, constant. not snap reading

I agree. The Cummins I6 is not really better just because it is an I6, it's just built to live in an harsher application.

Huh? It's not better, it's just built to survive... better? This seems like a flawed rationalization.

The Duramax comes out of the factory in a high state of tune - and it performs well as a light duty workhorse for the consumer market. The Cummins comes in a fairly light state of tune and is really targeted at the medium duty commercial market. It does have the ability to run at a much higher level though - and it pretty popular with the bombing crowd as it is built to handle an incredible amount of power. Dodge wrapped their truck around the engine, GM designed the engine to fit the truck.

Isn't the Duramax an oversquare bore engine? That's not exactly the recipe for a commercial workhorse diesel. It's more in line with a high performance, high-revving gas motor. A CAT makes for a better comparison engine for the Cummins. You wouldn't seriously try to compare a Duramax to one of those, would you? :D

"Better" is a relative and opinoun oriented term anyway. Most people claim the superior durability of the Cummins to the fact that it's an I6. I don't think the fact that it's an I6 has anything to do with anything, FWIW. The Cummins has a longer design life because of the other applications it was built for, not because it's an I6, that's all I'm trying to say. I don't think one is "better" then the other.

you wouldnt seriously try to compare genius CAT technolgies like HEUI to common rail would you?

That's pretty subjective though!

An inline design has a natural advantage of having more bearings to spread the load over. It's better for longevity, but if you are trying to get maximum power out of a fixed amount of space, the V configuration give you more pistons to work with. I think most Cummins engines will outlast the truck they are in. It's a nice feature - and it makes for a lot of nice donor engines - but it isn't exactly what the manufacturer was targeting.

As to HEUI and common rail - personally, give me a P7100 and I'm happy! Electronics suck!!! I kinda like the low tech approach.

Electronics suck because you dont understand them?

Everyone I know that hates anything electronic/modern/having to do with creature comforts, its simply because they just dont understand it; its not what they grew up with and learned about when they were in the "learning stage", "so it must not be that important"


theres nothing to not like about electronics. They are the future and here to stay; people can either embrace them, take the time to learn and understand them (its not rocket science) and appreciate them, or they can choose to shun them and be left behind in their own ignorance.

Manual brakes and steering worked fine too and did the job with no issues, I suppose you would take those over power brakes and steering as well?

JMO, no offence intended.. :)

No - it's precisely that I do understand them that brings about this opinion.

Only - I grew up around computers. I excelled with them. It was my easy major in college. I interned at THE biggest name in software while in college. I worked for a major aerospace company as a software engineer prior to even taking a software engineering course in college after that internship. I outearned my professors. I make pretty damned good money programming computers now - and have for the last 21 years. I prefer not relying on them for my transportation needs.

And they can also take the time to walk home when an inexpensive sensor gives out and they cannot make their vehicle run. Then - they get to pay a "technician" - who could not figure out how to gap a spark plug if their life depended on it - swaps parts until he hits the right one that allows the vehicle to start up. Or - invest a lot of money into equipment to allow them to diagnose the problem. No thanks. I'll take a mechanical approach and get home every time.

That would depend on the vehicle, wouldn't it? I'm not sure you get this point though - both systems are mechanical in nature, no electronics needed!

JMO, no offence intended.. :)
None taken. I've owned a LOT of vehicles in my life. In high school and early on in college I regularly bought cars, fixed them up and sold them - trading up. All of my favorites did NOT have much in the way of electronic controls. The fastest ones, the best handling ones - and the ones that were the most durable - were all mechanical systems. The ones that were a major PITA and cost the most to fix were electronically controlled systems. They really make a car "disposable". They really are only about emissions.

I'll give you this much though - on a wet road - ABS and traction control can really help out when you have a lot of horsepower!

Also - and this will hurt the Duramax fans greatly - the old 12v Cummins is still top dog at the track. The Duramax crews are getting close, but the fastest ones out there still admit they are chasing down 12v's! Yep - those mechanical beasts still rule!!! Not bad 10 years after the last one rolled off the assembly floor. :D

PS. The spark plug gapping was brought to mind while shopping for bike parts for my wife. At the Harley parts counter, the salesman informed me that the plugs were gapped from the factory. I almost laughed in his face! What kind of a tofu-eating sissy place is this? It's all about fashion now. They don't carry many parts for older bikes and the folks couldn't identify some of the parts I was asking for - for a '95 model!!! The new Harley image seems to be more in line with some kind of 'Pride March than anything!!! I gotta get some T-Shirts made - "Real Bikers Ride Harleys" in front, with "Side-Saddle" in back... maybe with a metrosexual posing next to a Fat Boy while holding a latte!!!

Hey is the 4.5 out yet?
I saw a brand new Suburban 2500 yesterday with the towing mirrors. Going up the road and the guy was hammering it down. It WAS NOT A GAS ENGINE. It sounded like a diesel. but it was fairly quiet. It was a sharp looking burban.
I am pretty sure its a diesel b/c a guy down the road for me works for GM and I have been seeing vehicles in his driveway over the past year way before they are for sale on GM Lots.
Just Wondering

tell me where it is, Ill go take pictures of it and get 1000's of dollars for them!!!

anyone that rides harley rides with pride because they are the best bike out there has nothing to do with a pride march maybe for you it does.and thats true they dont carry alot of older parts but neither does anyone else for that matter they must be order in cant stock eveything.never had a latte never will straight black coffee for me. are you sure you are not a metrosexual talking about side saddle and lattes like you know all about it.

point taken, I didnt really mean to come off as much as an ass as I might have sounded like. :o: :)

If the inline 6 is not a superior design, why do we not see any v motors in anything larger than smallest of the medium duty vehicles?

you wouldnt seriously try to compare genius CAT technolgies like HEUI to common rail would you?

HEUI Sucks ass. We have it on alot of trucks at work. We had two trucks last month that the injector pistons stuck and washed the cylinders. JUNKED. Give me a bosch commonrail any day.

LOL - I only know from what I observed at the Harley dealership...:D

Best bike? Maybe you need to get a wrench and start taking off all of the "made in Japan" parts off your bike. See what's left when you are done! :eek: I've done all of the wrenching on my wife's bike and I think there are more American made parts on my Kawasaki!!!

Harley isn't the company that they used to be. When they went upscale, they left behind their old crowd and started catering to the yuppies. It's a fashion thing now. That's why there are so many nice, shiney late model, low mileage bikes out there. They don't get many miles on them with their owners just posing next to them!

Now - go try some tofu and a latte. You'll probably like it! :D

DuraTOthemax. Ill PM you Wednesday night. This "guy" had the hybrid Tahoe in his yard a WHILE ago like a long time ago.
I go by his house Wednesday morning, if its a Blue Suburban in his yard, its a Diesel.
I'm in Newtown.
Stop by after you take the pics, You can split the money with me and have a couple cold beers on me.

I think the I6 is cheaper to make and assemble. Plus the medium duty vehicles don't have the packaging concerns that light duty trucks do.

You're just not looking. In a truck, inlines are easier to work on. Things are more accessible. One friend just repowered a dumptruck with a V-Detroit Diesel. And a friend's 105,000lb boat has a pair of large V-12's, and we're talking heavy duty here. And V's are what go into all the newer high performance mega-dollar yachts.....also heavy duty.

V's typically mean more power in less space. Detriot and Cat have made plenty of V's and I believe neither make light duty stuff. They all have there places, and as long as the CTD and the D-max are competing against each other, these arguments will be around. I think they are both wonderful engines I just won't have another Dodge vehicle. Now back to the 4.5, I sure hope they put it in box vans.

rememeber the cat 3208 ran forever

rememeber the cat 3208 ran forever
Yep, made good power, but were thirsty...wasn't the best idea to be non-sleevable, but it was still a good engine...

Is it just me or do the mirrors look like they are "leveled" in the pictures? I would love if they re-designed them to be level so we dont have to do the "tow mirror leveling" mod.

When i was on the fire department, we had 2 cat v8 diesels, one detroit v8 diesel, and an isc cummins 8.3l. The 2 cats were complete terds. The detroit was turboed and wasn't too much better. The cummins was scary fast even with 1000gal of water on the back of it and who knows how much weight in fire hose, pump body, etc. I'm not making statements based solely on opinion. I have a little bit of experience in the matter. Inlines are just the way to go.

on some forums it's been called a 1500hd diesel, but the pics show a 6 bolt truck=which is obviously a reg half ton.
Will it be a true 1500 hd or is it just a half ton?

they fixed this on all the 2007.5+ new body style trucks. :) :cool:
