Let’s the builds begin @Unclepooly 😉 I smell a drag race with big baz with lots of cheesy fast and the furious liners lol

[@Ahhhhhhh1983]

Really enjoying this build. Not sure if you guys watch your vids after you post them. It you have some wonky stuff going on with your focus on the cameras. Makes it really hard to watch and couldn’t finish the video. Hope this helps for the future. 🤙

​@Ahhhhhhh1983 you been sniffing diff oil again mate? I didn't see any wonky stuff.😂😂😂

Gday buddy I'm in Australia I'm getting a lil old but got a 12 valve p pump manual in my shed here in New South wales that's begging to get in the 86 square body that's sitting outside Mine won't b as elaborate but still b nice engine and box out of 96 2nd gen 2wd ram it's not the 700 hp I want it's that nice big block torque At low rpm I may head for an Allison 6speed when I get sick of shifting and clutches Still promises to be fun light And not 2 complicated Cheers

[@TJANDMAC]

Thanks ! 🙌

[@stuartkcalvin]

I saw a Garage 76 T-Shirt. They're now in Queanbeyan and banned me from further work and servicing, simply, because I complained about bad services - replaced an air filter when not necessary, replaced cabin filters when not necessary, post-OEM upper control arms not greased, screwed up a tyre rotation with TPMS fitted, left the drivers window down on pickup in a main street and the tug unlocked. Didn't empty and clean the catch can, nor drain the secondary fuel filter as requested. Despite being a 'Master Tuner', I got a vanilla downloaded tune despite my towing requirements. I had to pay another dealer for a custom tune - $1200 as Garage 76 wouldn't rectify their obvious error. There you go, lesson learnt, shop around.

[@Serpentiime]

Bloody loving the content boys and Love that pooly joined KZbin as well.

Thanks so much !

The tech used in this build is next level. Soo awesome, wish we could have done this back in the day. I mean its probably still not available in Darwin NT we are still years away 😂

American here! I use to run these 6.7 Cummins trucks for work. I asked my buddy who is the mechanic if you can run the 6.7 at a thousand horsepower with stock rods, he said “for a little bit”. Sounds good to me 😂

[@leekelly3875]

Absolutely pumped for this build!

[@CarlosDias74]

You really should build a 6mm stainless guard to fit between that 8hp and the truck body, saw some videos of gear boxes exploding and I can tell you that if they make BIG holes on the floor, imagine what they can do to you… stay on the safe side!! Awesome build mate 🤙🏻

[@TJANDMAC]

True ! Thanks for the tip

[@macpreston]

Haha yes i did see that, but i also saw what they were trying to do! Safe to say i wont be holding a hydro handbrake on and redline shifting gears that whole situation made no sence haha

[@DesignedandBuilt]

Hahaha nah XXXX sucks. Love this episode guys, these guys know their stuff and really enjoyed watching it all. Can’t wait to see that 8 speed get annihilated 😂🎉 Big project, huge amount of work, keep killing it! Let me know when you want some pretty pictures ❤

In the UK our 18T box truck has that engine, running well past 1million k's. Seeing you guys strap compound turbos to it is hilarious :)

[@krisolof7998]

NV271 should be available as a bolt on for your transmission and is designed for a GVWR of 17,500lbs. 2:72 low range and used in sled pulling in the states. I believe they are all left hand drop but you need a bigger front axle anyway. There is also a kit to convert to a divorced case if it comes out of an f-truck which can help with packaging. The 273 is the same case but in electric shift

[@macpreston]

Thanks mate! I may end up biting the bullet and going something expensive but for the moment well test out the patrol case!

Ahhhhhh Mac, 38 minutes 35 seconds in, I have to say I'm the exception to the rule here, as having a fun hobby offroad channel on KZbin, I don't edit out the mistakes. I want everyone to take away something from my channel, from how cringey I was offroad at the start. to learning where i miscalculate and stuff up on the bigger tracks. But anyway, loving the video and build, and frothing for more buddy!

15:05 Btw, those 90% over nozzles are good for about 900whp... idk where your boy got 1200hp from. Also; RIP con rods.

[@macpreston]

Copy that! I think my fuel pump will max out at 800ish anyway until i got to a 14mm, That will be the point i think well do rods and overhaul!

What adapter did you use to mate the 8hp to the 6.7? Couldn’t find any of the shelf

[@KingyY62]

Haven’t been waiting for this at all 🤠

[@danielschutte3839]

This is awesome mate!!

[@ECES69.]

I make right around 1000 hp with a big single turbo on a stock bottom end 5.9l. It's been reliable so far. I know quiet a few guys that have been making 1000 hp with stock bottom end 6.7l's as well. The general rule is to keep the torque numbers lower at lower rpm. The high torque numbers at low rpm are what kills the rods. So needless to say, tuning is a huge part of it. How heavy your foot will be is also a big part. Great video, just found the channel today. Hope this helps a little.

[@macpreston]

Great info to hear thanks mate! And every bit counts mate welcome to the channel! Do you run twin pumps or just a single 14mm?

[@ECES69.]

@@macpreston single 10mm pump with 150% over injectors. Airdog 150 lift pump.

Pwwoar TJ and MAC this is perfecto!!

[@TJANDMAC]

[@brianlau8316]

👀👀Definitely need more intercooler👍👍. Thousand horsepower totally doable as long as you keep the power higher in RPM

[@jaisout]

I was also looking at the 8 speed for my 800hp compound 12 valve cummins swap (I have an 8 speed behind a LS and love it) but when I did the numbers, the math don't math. Even the best of the best built 8 speed box from a well known 8 speed builder in the states wasn't sure if it would hold up to compound 5.9 cummins torque numbers. 6.7 can make more torque than the 5.9. I have gone the well known and tested direction, 47re with goodies. The 8 speed might be good for 1000hp but it wont like the 2200-2500 lbft torque.

[@TJANDMAC]

Yep well, the guy building seems to have some faith so we are all interested! Watch this space !

[@adrianbruenjes3952]

This is an awesome build guys! But don't let this distract you from the fact that Hector is going to be running 3 Honda Civics with spoon engines. And on top of that he just came into Harry's and he ordered 3 T66 turbos, with NOS, and a Motec system exhaust.

[@TJANDMAC]

😂 I know right , we r gonna need more turbos 😆😆

I think youd want the 1.32 housing on the 480, I've got a very similar setup on a mechanical 12 valve. But with the 1.15 rear, drive pressure will be mad on your 6.7

[@got5w4q22]

Definitely rods for 1000 too, street fighters are cheap

Ah cheers mate! Yeh thought that might be the case! What fuel pump and thoughts on fire ring the head?

[@got5w4q22]

Not too clued up on the cp3 but I think a 12mm exergy would do everything you want. 100% go fire rings and haisley gasket or similar with arp625s
