Is Chevy REALLY Building a New 8.3L Duramax Diesel V8? 

Then they can’t sell you another one in 6yrs

@@pryme2013 yessir. buy rinse repeat

If you're living in a climate with that much corrosion you need to occasionally wash the truck. Saying the frames rust in 6 yrs is a little melodramatic.

how about you not use salt on your roads like its a Columbian prostitutes?

I don’t understand why in 2024 they can’t apply a type of epoxy to the frame & underside that will seal out the salt & brine ? This is not rocket science I believe it’s planned that way so you can buy another in 10-15 years. Lol

But that would make sense

Cadillac 500/8.2 Liter V8:🗿

Maybe the bigger anchor up front will add enough weight to control the 8million pound trailers they would advertise it could tow

i’m thinking they can run lower boost and clean up emissions and run them at a lower tune

Totally agree. One thing sadly overlooked by reviewers are the DEF, regen and other emissions system hassles and their costs, all of which have ruined diesels for me.

Lmfao

And it will get 2mpg in Diesel Extortion Fluid

​@@motofunk1pay for your own pollution. My lungs dont needs to subsidize your emotional support truck

@@cptbuiltk7944 You're assuming these systems actually do anything for your lungs.

Regen emissions systems are smoke and mirrors. They are designed to make the unthinking accept the BS idea that EVs are a rational replacement for the internal combustion engine.

…… and operating at higher temperatures which kills an engine. It’s almost like people are waiting in line to throw their money away.

i dont think they will need too many exhaust treatment systems. theres a company (i forgot the name) that is experimenting with hydrogen injection on diesels, which will reduce the amount of NOx and CO2 emissions the engine makes, which means maybe we can get LESS exhust treatment systems. of course the only way to completely get rid of those systems is to convert to a supercharged hydrogen combustion engine with water injection. the water injection on an HICE engine completely eliminates those NOx emissions (hydrogen alone already makes zero CO2), nd hydrogen engines love boost, which is why it would be supercharged. then they cn strap a beefy hybrid system to it for more power

To hell with all emissions. Federal fraud. Makes them money and cost consumers. Make diesels normal.

@@mikeburke932 facts. There’s ways to tune diesels so no black smoke is produced, making them as clean as possible with no emissions equipment on it

Of course it’s gonna be a V8!!! All their diesels are v8.

GM doesn't have a 6.7 .

Where did he say 6.7???

@@DLVRYMN I think it's 6.6L

From 403 cubic inches to 506 cubic inches

400 cubes to 427 isn’t worth the time, they’d at least need to go for 450

No, 1000hp is barely livable daily. 1500hp seems a good all around number.

Bigger engines might be a strategy to improve general reliability.

I’m a sometimes truck guy. Sometimes I need a truck, sometimes I don’t. The ridgeline is enough for all the truck like things I would do. My closest friends are diehard truck guys, towing boats and travel trailer weekly during the summer. One of them has a GM 6.2 Denali pickup he tows with and it he tells me it’s the best truck he’s ever towed with. My question is why does 1000 lb/ft of torque have to be the standard and not something around 600 that’s reliable?

@@Heffelz8 Because it’s more. I mean, that’s it. That’s the answer. A Ridgeline is a minivan with the back half cutoff up top and formed into a “bed” so they need like 250lb-ft. When you’re towing in excess of 20, 30,000lbs, torque is king. 600lb-ft works, 1000 works better. And all things being equal, more torque is more reliable and in theory more economical; if you only have 600ft-lbs, the engine has to work harder to maintain 70 where 1000 doesn’t. This is all prefaced by saying with torque limiters and tuning, you’re not rolling around with 1000ft-lbs. It’s capable of making that…. A lot of fleets run low power, thinking they are saving fuel and saving parts. And it’s the biggest lie ever told and not realistic in any version of reality.

@@wyo_garage20I’ll keep this in mind whenever I see all the trucks towing 30k lbs down the road. I think it has more to do with auto manufacturers attempts to have “best in class” when in fact 95% of people will never use their trucks to the extent of this. You answered it exactly as I thought somebody would, defending it as “better” without addressing how much power 600 lb/ft really is when comparing it to 1000.

Some people are too fixated on numbers when they should be fixated on reliability

Why mention the trim when talking about engines 🤡🤡

So is a pound of ground beef

Those that are well equipped don’t care about the price😎

that’s not what’s driving up the prices it’s the technology and the bills and whistles.

Competition with. Cummins in medium applications is more likely than a 2500/3500

Yeah this is definitely for the 4500 and 5500.

I think they'll go over 7.3L if for nothing less than marketing reasons.

Light duty (2500 & 3500 and even F550) engines are the same in the medium duty (4500+ Chevy or F650+). I would love a 8.3L Duramax but if it’s a hybrid will be a maintenance issue and will never sell.

Exactly. If true, it would be used for medium and heavy duty trucks, not pickup trucks.

Power sells!! Unfortunately the Big 3 have convinced the masses that they need the power of a semi truck to tow their little boats and campers. Just remember when you see an older 10 wheeler dump truck towing a big trailer with 40k lb excavator on it, that truck only has a 7 to 9 liter engine in it and at most the 9 liters makes 1200 ft lbs. 15 Liter semi engines make around 1600 ft lbs. No need for the ratings in these pickups other than marketing hype!!!

Exactly, larger displacement under stressed engines tend to last a bit longer.

@@GMCJay_lly The problem is, the issue isn't really the displacement of the engine causing them to fail sooner/more often, it's the requried by law emission equipment (which would also be on this 8.3L) that make diesels expensive pieces of shit these days.

The current generations of HD diesels already make stupid amounts of low-end torque.

@@nathanmcdonald610 theres a company that is experimenting with spraying hydrogen into diesels to lessen emissions. so some of those emissions systems can potentially come off and be weakened if GM were to add that to its engines. but the true way to go is a supercharged hydrogen combustion engine with water injection. the water injection gets rid of the NOx emissions, the supercharger feeds it the air it needs, and then they could also make it hybrid

Engine braking, hopefully not breaking.

Long live the LMM. Most capable and reliable vehicle I’ve ever owned

Your LMM also doesn't meet emissions, so it cannot be built anymore.

Your towing needs and my towing needs are completely different. Towing jets skis you should be good.

Lmm will pull a house down all day long

@@Southrn_Maniacyago Exactly. Those who say otherwise have never driven one

They should make the L5D 350 hp detuned duramax an option for the 2500 and 3500 trucks , it will still get the job done just fine with 700 lb ft torque and be far more reliable

Make the transmissions and electronics more reliable too.

It’s impossible to make dpf systems reliable

An under stressed larger displacement engine should last longer.

GM is doing exactly that ....reliable power from a large Eight Three !

The 10 speed Allison leaves a lot to be desired when used at higher GVWR.

​@ChaseLandMgmt that 10nspeed is "Allison" branded. It's the same 10 speed internals as the Ford 10R140

@@ChaseLandMgmtBecause it’s not an Allison. GM paid for the right to use the Allison name. Even the older Allison 1000 which was technically built by Allison was designed for what GM was willing to pay for and for how GM wanted it to shift. GM thinks that they know more about building HD automatic transmissions than Allison does . I would disagree.

Even your 07 has emissions equipment tho lmao (EGR)

@@loganamurray64 yeah but no DPF or DEF! The two killers for diesel engines.

And as we kno , Chevy med duty truck is no longer Chevy, it was taken over Navistar ihc commercial I hope the truck made at ihc continue as built by ihc much heavy-duty by conpair of size of parts !

125000 dollars inflation

The block will likely be updated but still similar in size as current. Stroke and bore will increase. In medium duty output will reduced if such route is done. Because GM has two brands costs can be kept uncontrol. To be honest Ford should have taken this route but probably wanted to keep costs down.

It wouldn't have to be much larger at all. Hog out the block and give it a longer stroke. Would fit in the same space.

Displacement increases don’t necessarily mean physical size increases. The Ford 7.3L gas engine is physically smaller than the 6.2L V8 it replaced.

yeah but 8.3L displacement

Not more braking, better tires imo. You can lock up the brakes in a Duramax ezpz

F450’s have good brakes. As far as engine braking that’d require a different valvetrain and the engine would have to be made slightly larger to incorporate brake pack under the valve covers. Updated oiling systems as well to supply oil to the brake packs.

Yes!!!

Yes! I'd love to see an independent review of Edison motors.

they dont have any trucks..freightliner.

You're right, but the will have pickups very soon.

Agreed

454 7.4 would be good too.

They have the 6.6 gasser...

@GMCJay_lly that's not a big block though and thr 6.6 was to replace the 6.0 gas. They need a replacement for the 8100

And the ford 7.3 has spanks GM’s 6.6 gas so they need an upgrade

Could probably get over 2,000ftlbs of torque easily.

It's coming!

Yes I agree. I think that’s an excellent idea. Or make the 8.3 a big block gas. Which what I thought this video was gonna be about.

I'd like to see an ecoboost 7.3 or at least a 5.0. I think there's a lot of potential there for decent towing economy in a gas engine.

@@leviduff2740 People put twin turbos on their 5.0s and they put out very impressive HP and Torque numbers. GM is currently working on a Twin Turbo 5.5L LT6 with dual overhead cams and a flat plane crank.

IDK I feel a 8.3 gasoline would be more reasonable

@@447Filmdidn’t they have a 8L gas v8 in the early 2000s for the 2500 trucks?

@@cobrademon761 Yep, a Vortec 8100. And considering that the aftermarket has already been pushing the LS architecture to past 520 cubic inches (through blocks with taller deck and bigger bores), it's not impossible for them to develop such engine.

@@Roddy_Zeh don’t forget that the 8100’s are super popular in the marine industry. A properly boosted big block (400+ cubic inches) could dang near have the same numbers of some diesels.

John Deere has an engine that runs 174 ft-lbs/l. Their new 18L puts out 3135 lb-ft of torque.

Yeah but those semi engines are designed for 1 thing mainly & that’s long haul trucking. Low rpm at 60-70 mph

Semi truck engine do have issues especially with emissions engines. Def is no good for engines over time. They clod the engines up with slime. The pre emissions engines last alot longer and are better the emissions engines. You don't see emissions engines having a million plus miles like the pre emissions engines

the dodge and ford monekys are only smart enough to look at power ratings

@@rock-uu7qr meanwhile the gm fanboys are replacing their broken crankshafts

Easily, I think the 7.3L is the best bang for buck engine you can currently get in any 3/4 or 1-ton truck.

U need to beef up Ur DD13 to 650hp & go with 13spd or 18spd

Ita for more tq with less emissions .

I can assure you we have lots of GMC 2500 & 3500 L5P trucks in Australia. 5 of them live in my rural town alone.

@@Ozgrade3 3500 duallys well I'll be

@@79series yeah they are getting popular. Every 2nd tradie is now in a RAM 1500. Lots of the trucks were privately imported and converted, ASV are very popular for conversions. I started promoting these trucks 12 years ago " nah mate they will never sell here, too bloody big for our roads". Well RAM has sold 27,000 of the 1500 model here.

The problem is, more powerful or less powerful all diesels have to emission equipment and DEF from the factory by law and that's a big part of where the asinine cost of modern diesel engines come from. So if Ford for example, we're to offer a significantly detuned PowerStroke that made say 350hp and 750ftlbs of torque, it would still probably cost just within a couple thousand dollars of it's HO 500hp/1200ftlbs of torque version and when people are spending at minimum 65K on a vehicle, they will probably just opt to get the most powerful engine available if the cost differential isn't very big. Honestly I think Ford has the right idea with the 7.3L gas engine. It's relatively low output for it's high displacement means it's an under stressed engine that should have no trouble lasting decades into the future and because it's a naturally aspirated gas engine it's far less complex and expensive to purchase and maintain than any modern diesel, aside from all that it's 430hp and 480flbs of torque is plenty for like 90% of what anyone should be doing in a 3/4 or 1-ton truck anyway.

All depends on what applications it gets used in. HD (commercial) trucks are tested/rated differently from the standard car/light duty pickup. Ford gets 500 Hp out of the ford pickup engine @ around 4,000 rpm. That 8.3 might redline at 3000 rpm. The torque will probably be higher, though. This is a bit apples to oranges (I-6 vs V-8), but if you look at a Cummins 9 liter, you can have HP from 260-380 & torque from 860-1250. Even jumping up to 15.0 Liters, you only see HP #'s ranging from 525-565 & torque 1650-2050.

That ford HO powerstroke engine is overtuned and unreliable. Just see on RU-vid fow Ford is replacing engines under factory warranty on trucks with low mileage

​@@jeffs2809 You know that torque and hp are related? Ford makes 1200 ft-lbs @1600 rpm, 500 hp @ 2600 rpm (not 400 rpm). If 600 hp/ 1200 ft-lbs is correct, that would mean that this engine would produce either torque or hp (or both) at higher rpms.

I believe the upside in engine liters displacement is for lowering the Nox# and Emissions not exactly for HP/LB-FT. John Deere is a prime example their new JD 18L Engine if I recall correctly has lower emissions output than the previous top engine JD 13.5L engine and has no DEF while delivering up to 908HP all due to the larger size of engine displacement.

@@midengineZ06 I’m reasonably sure that, with ag & construction equipment, “size matters”. So, once the engine gets large enough the emissions restrictions are loosened enough that they can get away from some of the equipment required on smaller displacement engines. I can’t say that’s entirely for certain, though. I do know manufacturers have been able to put out some equipment without having various emissions equipment while still having “mid-size” displacement engines. I didn’t really dig into the details of how they were accomplishing it, though. I know the general idea of decreasing compression ratio = lower combustion temps = lower NoX, but that’s also going to take away from performance and won’t completely eliminate NoX without egr or def/scr(diesel of course).

Technically it would be international.

Ford is already making a 7.3. It’s is a gas engine. Also the 7.3 diesel made a whole 260 hp and a little over 400 lb/ft of torque.

Only if ford can re tune the engine to make more than 500 hp

@@jackylsmith8138 They could in theory bore/stroke the current 6.7L out to 7.3L for extra power/torque. The 7.3L would like just be an arbitrary number used to attract people who fondly remember the old 7.3L from 20+ years ago.

the 2.8 duramax 4 cylinder can outpower the 7.3. the 7.3 couldnt even come close to the duramax the year it came out let alone an 8.3 litre one

Hybrids only make big power for short bursts due to battery size.
