600hp should be around 1200 lb ft torque. A fun daily driver for a 6-7000lb truck.. Definitely not disappointing. Diesels are expensive, this is common knowledge so... Have you driven a 600hp lml to justify making suck a statement.

[@alexandertaddy4639]

Jason Heinrich I had a 6.4 powerstroke. I deleted it and tuned it. Very inexpensive hardly any parts. Dynod 567, 985 at 30psi. On the street it would run 42psi. 8000lb truck. It was lots of fun. I’m saying keeping the emissions intact takes away a lot of fun. They were shooting for a thousand and got less than 600. That’s a lot of money for it a lot of return. If it was my truck I’d delete it as soon as the cameras were turned off lol

[@edwardmyers1746]

[@JohnDoe-gz8dw]

It's a balance weight because the engine is externally balanced. It reduces harmful harmonics in the bottom end of the engine. It keeps the engine from destroying the main bearings.

[@freedomfirst5420]

Yeah, noticed that.😄

[@jfrost42688]

My completely stock l5p Duramax will run that

[@chesspiece81]

I had a bagged 2005 3500 Duramax with a turbo back exhaust, Banks intercooler tubing with the stock intercooler, LBZ mouthpiece that I ported myself, a couple 90° 4" couplers 4" pipe and K&N filter on the end of a tune, Duramax Tuner's 450 whp tune using EFI Live and consistently went 14.2 at 97mph back in 2011 in Alabama in the hottest part of summer. With a built transmission and lift pump I would have safely run DT's 600 whp tune and easily run mid to low 13s. 8.9 in the 1/8th is a 13.95 roughly in the 1/4 so that's not too bad keeping all the emissions. Now ditch all of it, run a really hot tune and run deep in the 12s.

Nick at Duramax Tuner is awesome. I don't know if he still does it but a one year subscription for $300-500 got you all of the tunes he has written for all generations of the Duramax. I went from 16.0 with my bolt ons to 14.2 with just his tune on a LLY. And I still got 18-22 mpg in town with his tune. This truck's numbers aren't an accurate depiction of how fast his "race" tunes are or how economical his MPG tunes are, or how good his damn tow tunes are allowing the stock VGT to act like a Jake Brake helping slow the truck and it's load.

[@Donovan.Creamer]

Congratulations...all that work and you can almost outrun a stock Honda Civic. Hahaha

[@mr.lowslow7702]

That’s cause they kept stock exhaust. Don’t want to get chased after by the epa. They built the motor for 1000hp and then realized dpf couldn’t handle it and they couldn’t delete it. Trucks running at like 580hp they said.

[@SGTJDerek]

All these comments about the time slip and the power level they SHOULD be at. If you watch the beginning of the build, the parts used COULD handle more but you wouldn't pass Emissions in any way, shape or form. And that alone is an issue for a TV Show. Just look at The Diesel Brothers. How much hot water are they in right now? EPA has dropped the hammer on Tuners as well. BUT, just as we saw in the '80's, technology will catch up and the limiting factor, DPF, will eventually get better as well. It'll take a Hot Rodder in the vain of Gale Banks to do it but it'll get there. He is such a Geek he's already miles ahead of everyone else. Including the Factories.

[@overyonderjustapiece]

I can’t help but laugh at these guys. 20-30 seconds and they talk about it “getting too warm” cause of no cooling system. Clearly they have never tried starting one on a run stand and let idle to help seat rings. I mess with LS engines and always run them upwards of 3-4 minutes before shutting them off with no coolant. Never had an issue.

[@tylereast9622]

Oh yea the LB7 had 480k miles on it as well haha

[@thelifeofmatt0306]

For real man, not sure what these guys are up to on the line. My 7.70 truck is a 640 whp LBZ. If it’s a cool day sometimes that busts 7.60.

[@poot111111]

At least they posted the video after the puny 1/8th mile.

[@illesskilla]

All that work on the engine just to make that power the stock components could easily handle no problem because they wanted to keep the emissions systems in tact!!!....i deleted everything on my 06 lbz and added a cold air intake system, straight pipe exhaust, ppe downpipe, egr deleted exhaust turbo pipe and with a $75 used holley flashpaq tuner oh and 500k miles on it and is very fast for a 8k pound truck

[@eddierodriguezjr274]

Hey I got an idea! Let's waste 6 months of our lives and thousands of dollars to build a duramax engine capable of 1,000hp, only we wont push it past 600 because of emissions restrictions. C'Mon guys you could've hit those times with basic upgrades. I've seen gm diesels hit similar times on a tune. If you're worried about the emissions whyd you build this.

[@captainr.8882]

NO WHERE NEAR enough bang for the buck in this build.

[@lowranceajl123]

I like how that have to act happy about such a terrible outcome. The emissions absolutely chokes performance out. Yes 580s is okay, maybe even good for a car. But a 7k lb truck its barely any better. If it was a truly open show they could come out and say how they were just as disappointed as the viewers here. With emissions becoming more and more strict shows and products will slowly become more and more watered down until it is all black market.

[@pbalerig]

[@Dying2Live220]

Seems like alot of money "building" a truck to not crank it up for the original 1000hp goal.

[@TAGDIESEL]

Don't know what your turbo is or if the heads were just new stock ones put back on. I would've expected a bit more out of it considering you can push into the low 500's with just the basic 3 upgrades. I think that truck would run faster in the 1/8th as well, i didn't see a boost launch .🧐

[@1986z28owner]

Comical that theyfired the engine without a cooling system. Not like initial fireup is critical in seating piston rings or anything. I hear getting the rings and cylinder walls hot with no water is ideal.
