"Whatever it takes to get on the list" I like this guy!!

[@mytmousemalibu]

Im a Dmax fan 1st & foremost but I was wholeheartedly expecting sparks, smoke, coolant, oil, and bits of hot metal on the floor! The stock rods aren't well known for surviving 600/700hp. Impressive!

[@warrior641000]

You and I both. I could hear my LML outside quivering once they smacked 1200. I figured the crankshaft would become quick disconnect

[@100pyatt]

Tuning is a huge determination Factor in HP/Tq durability

[@mytmousemalibu]

@@100pyatt Absolutely, im sure his tune was a big factor in that working, limiting torque, etc. They didn't lay into the spray till it was already up into the pull pretty good, any early probably wouldn't have turned out good.

[@ATVer85]

I agree with all of these comments! Pucker factor!

[@c177pilot8]

It’s not the horsepower that hurts them it’s the torque. Try to keep it under 1300 and they are fine.

[@charles15519]

Looks like the motor was going to come right out love it

[@h.h.legacydiesel6724]

Awesome❕l run a stock L.B.Z., SURPRISE - SURPRISE. I thought the last pull , well was the last ever pull! Dang, that is one stout stocker. Thanks for sharing 👍. 👌🏻👍✌🏻🌤 🇨🇦 😎.

[@fasteddie8225]

That’s crazy on stock head studs

[@rc4lifebnsf]

I’m at 310k on my tuned stock lb7, stock head bolts and I’m nervous when she’s gonna blow hg’s lol

[@Blackneck1994]

Showed up with I beams, left with S beams.

[@oinchadoomandwolfboy]

I’d like to see a 5.0 Cummins pushed. Bet you’ll detonate the transmission before you blow an engine.

[@luisdasilva2324]

Mark my words I will be on that list ! Love y’all 🙌🖤

[@tommykuebler323]

Almost 300k miles? That motors just now getting broke in.

[@shemwhitehead9517]

Holy crap!! That intro deserves a like by itself!!

[@N.A.J.]

I dont know which is better. The fire cracker intro or the stock duramax making such a huge number on the dyno. Both are awesome!

[@lanegeisewite1436]

Dmax powaaaa!!!!!🇺🇲🇺🇲🇺🇲💪💪💪💪

This makes me wanna come out there. 😎

Say when

[@builtbyme]

@@FirepunkDiesel i live in NJ but one day for sure.

[@Detroitcustompainter]

Hey guys glad to see ya'll strap a Dmax down. I have a 2015 LML that I'd like to add to your list. You mentioned it had a 48re swap. Is this something you guys could do on a lml?

[@FirepunkDiesel]

We can help, we buy the adapter plate and flexplate etc from suncoast

[@wickybuilt]

@@FirepunkDiesel curious if you’re familiar with the stand alone required to do this in an LML

[@Magucci13]

Why would you want to swap an Allison for a 48re?.

[@ThanksHero]

⁠@@Magucci13shifts faster, stronger.

[@cant_keep_up4123]

Talk about a sign or perfect timing or what. Always wondered if you guys messed or dealt much with duramaxs. Finally getting back into the process of building a 427 stoker s475/gt55 possibly 400% not sure injectors atm with 14m pump

[@broc212]

Is this not a record on a stock pistons/rods for an LLY?

[@lamarzimmermanmennonitefar5269]

That was intense! More rpm and more nitrous ftw!

[@barbaraepsaro2718]

I bought my 06 LBZ Duramax because I liked the sound . It's still my work truck and everyday driver

[@ethanhoullahan5423]

Where is the video of the L5P making 1300!!

[@specializ20]

Can you explain how it's possible to make that much power on stock head bolts? Why do so many people have head gasket issues and this guy can make big power.

[@134nick]

If he had re torqued the bolts before this run it might have helped it stay together a little longer

[@specializ20]

@@134nick I agree but 1400 HP?! That's crazy

[@RJisUnknown]

@@specializ20 he only did it those few runs. It 1000% wouldn't survive this for more then a few pulls. Shear luck the thing didn't grenade at this point honestly.

[@specializ20]

@@RJisUnknown that is true. But fuel only it dynoed at 900. Even that's amazing to be a stock engine

[@V8Lenny]

It's all in the tuning.

That’s crazy I was waiting for the Boom.

Got bro so hard in beginning clip 😂

I need to get my dmax inti you guys asap.

[@Temptingss]

siiiiiiiiiiiiiiiiiiiiiiick dude

[@b-radd-max7340]

You should make a video of the after math and teardown

[@bernhard8540]

Best intro ever haha

[@joeyriveira6697]

So is the variables same on the Cummins dyno pulls ??? Are they also on spray and the same setup ??? I’m good on fuel only as that’s real world scenario & reliable .

[@350orangecrush7]

This a lbz or a lly or a lb7?

[@jessebamford8633]

lly

[@thebitefight2601]

You’ll have my truck when it’s back together.

[@Meal_Team6]

Is a built 48 REALLY better than a built allison ? Seems like planetary gears would be better than drums and junk.

[@markcherry6513]

Built 48 is a “dumb transmission” because it dosent have as many electronics holding it back, so essentially when you want it in 4th gear for example it will go into 4th gear no questions asked and will do it faster than an Allison. That being said, both transmissions have their strengths and weaknesses

[@barneymiller7894]

HOLY SH!T 😳

is this thing still alive?? shits crazy lol

[@CountylineCrawlers]

This is why I stand by my lly. Lbz crank would’ve snapped already

[@4wdiesels]

Did I hear that right? 48RE swapped? Allison's can't be built to handle power?

[@det645]

Commin swap. "Easy to rebuild" and can "handle power"

[@TheHarbin22]

Allison's handle that power just fine. They can't shift as fast a 48 and weigh a lot more.

[@4wdiesels]

I actually had to research that a bit because I've never seen it. I guess for sled pulling, dyno and drag racing, the 48 is the better choice. If you watch sled pulling videos, lots of Allison trucks going into limp because of sensor issues.

[@TheHarbin22]

@@4wdiesels That's not really the case at all. Dyno and sled pulling is fine with a built Allison because the don't require quick shifting. Drag racing is the only time a 48 really outshines an Allison.

[@4wdiesels]

@@TheHarbin22 you learn something new everyday!

[@dangosh3340]

Wow. Minus the parasitic loss through the drivetrain. That things probably 1600-1700 at the crank

[@specializ20]

Can you explain how it's possible to make that much power on stock head bolts? Why do so many people have head gasket issues and this guy can make big power.

[@FROSTY2588]

It has a big single turbo, if it had a set of small twins it would have already chucked rods.

[@builtbyme]

@@FROSTY2588 i think it would have snapped the crank first to be honest, cause the firing order on the lly is all at the front of the crank. Thats why an af cam is worth doing when you add power to them. To change the firing order to be more spread out.

[@joshuaquilliam2887]

@@builtbyme That's a great theory but still not proven. The only sure fix for Duramax is a billet small journal crank. And no it's not all on the front of the crank lol there is 8 cylinders. All the Duramax trucks have the same firing order, maybe l5p is different idk about that one.

[@builtbyme]

@joshuaquilliam2887 changing the order (1-5-6-3-4-2-7-8 has become the somewhat standard change) helps disperse forces throughout the entire crankshaft. "With an alternate-firing camshaft, you're basically taking energy and moving it rearward, away from the crank's snout, where it can be absorbed by the flexplate. I have a 1000+hp fully built truck. Im pretty sure i know what and why an af cam helps the crank live. Its not a theory, its been proven. By wagler, socal, and many others. But wait cause i didnt know it was a V8 tho bud. 🤡

[@Dparsons116]

😱😱 woow impressive for a Isuzu lol 👏👏👏👏👍👍 wonder how much spray it will really take? I say give her more an let find out 🤔🤔🤔

[@ChrisPote]

What year of duramax ?????

[@Sentinel15]

would i be able to bring my 6.7 cummins for dyno tuning?

[@shannonsisk]

Why would you swap to 48re? Is the factory Allison better but a built 48re is better than a build Allison?

[@joshuaquilliam2887]

48 is a better trans for racing. Less shifting, plus the Allison is a catch and release style transmission so it binds up if you try shifting it too fast. It's great for hauling and daily driving, but for drag racing nothing beats a 48 or 4r100, and the 48 is damn tough once upgraded.
