ULTIMATE TOWING 12 VALVE CUMMINS

[@tommygreist9560]

You and Myer make a great team and great videos...Ive learned alot that I can do for my 06 2500 2wd. 1 day............

[@horsetorquesdiesel]

You can do it!

[@eazymacavelli8375]

Great build. Id love to see a 6.1 build step by step with part numbers and specs.

[@user-el4ii7zq6l]

The truck itself is a cummins holy Grail 1998 12 valve 5 speed 4 door 3500 4x4!!!!!!!

[@hubert-wf1xz]

IIRC the holy grail was a 1998 12 valve 5 speed 4x4 2500 quad cab with the short bed. Factory short bed being the odd ball and rare thing since the rest of the years and trucks all had long beds. Everyone has their own version of options they like and consider a holy grail truck though.

[@zackpalmer2824]

I have a 98’ 12 valve 5 speed manual extended cab, short bed 4x4. Love it. It’s a holy grail to me.

Me either!

[@ProjectNotSoSlow]

nice thing about a 12v is your foot is the tuner.

[@horsetorquesdiesel]

if you like going slow sure.

[@ProjectNotSoSlow]

Just trying to find a positive thing about 12v. I actually prefer 6.7 with Vgt turbo. I love my vgt turbo it's amazing how fast it spools.

[@horsetorquesdiesel]

@@ProjectNotSoSlow I like 12vs because you feel connected to the pump, and they rattle takes me back to my childhood. I just hate how expensive they are to purchase.

[@lauriestump7134]

Gosh, that's a pretty setup! And love that smile at 5:55.

[@horsetorquesdiesel]

They both seemed very happy!

[@jeffbeaird747]

Tow rigs are awesome I love pulling and (accidentally) spinning a tire, lol

[@tjboggs3710]

Ive been reading on a lot of Cummins forums that the 215hp pump retards timing at full rack travel but according to your video it advances timing does a Mack rack plug advance timing more if so how much

[@noprob364]

Pretty sure a rack plug will just allow for so additional travel in the rack at WOT I don't think it alters the timing at all. Could be wrong

[@robserrano7040]

Hell yeah that’s what I want for a Tow truck

[@farmboydiesel4569]

Please do a video on what it takes to put a 6.7 crank in a 12 valve

[@horsetorquesdiesel]

Nothing with factory rods. Some clearancing required with billet rods

[@davidwitcher5443]

Woohoo! 12V content!!!! 18* timing at idle? 24* at high idle?

[@CumminsWorks]

It’s more to do with engine horse power, it’ll cruise at 18* but slowly advance to 24 at full throttle.

[@witcher71]

@@CumminsWorks That's what I was guessing. Too bad those pumps are hens teeth.

[@woos31]

That thing would be a stoopid good time loaded or empty!!

[@jimkillen1065]

Look forward to seeing the finished product. I want a 6 speed manual but that just me . If you don't mind is it 4.1 or 3.54 gears . So look forward to seeing how it tows with a lower stall . One thing that I have wondered how the lower stall effects the brakes as sitting a stop light with the low stall trying to pull the truck forward . I could put up with that I guess for a better fluid coupling . And see some rpm drop at gear shifts . I guess that is a 913 pump p pump

[@CumminsWorks]

I have a g56 in my toe pig, it’s nice but for hotroding around town that’s a lot of gears to tow through. I have the same low stall converter in my shawty, sure it try’s to creep a little at idle, but I haven’t been able to notice a difference between it and any of the other trucks I’ve test driven. The truck has 3.54’s.

[@larrypeachy2391]

@@CumminsWorks how stout are the g56's ? That's what I have and I've heard a lot of differing opinions on em .... wonder how much they can take - dont really wanna blow it up just yet

[@CumminsWorks]

@@larrypeachy2391 honestly I’m in your shoes. Heard a bunch of things about them and not sure what to think. I’ve been running ~700hp in mine for 2 years now without issue, however when I built it I messed with some of the problem areas so maybe that’s helping, not sure.

[@bigmurph1447]

The 12v's are the best in my opinion. I have a 96 with compound turbos it tows great. The only problem is the 2nd gen truck they just ride rough. I was a f350 of f450 with a 6speed and the 12v

[@twintibbsdiesel93]

What valve springs would you recommend for a 2008 Ram 3500 Dually 6.7 Cummins with stock bottom end and stock head with S366/S478 Compounds ? I want to do push rods and valve springs at same time. I was thinking D&J springs and push rods ? I don't want to over do it I just want something that will handle 900HP and won't smoke my pistons .

[@horsetorquesdiesel]

Can’t go wrong with d and j springs and pushrods. Our PDD 4.5k and stage 2 pushrods would also work well! That’s what is in my 2007.

[@twintibbsdiesel93]

@@horsetorquesdiesel I am massively jealous of your new Engine and setup with the red paint on it ! Looks awesome.My valve springs and pushrods are on the way from Hamilton they had a deal for the whole package I couldn't pass up. Next is 12mm CP3 and Airdog Lift Pump. Then last 100% over injectors . Then I'm on to painting the whole truck and new rims and a new SRT Hood .

I’d love to clarify the turbo set up. You’ll probably do that in a later video. It sounded like you said a 60/67 with an S 400 on the manifold, just sounded backwards…

[@CumminsWorks]

I miss spoke. It’s a he351 60/67 on the manifold with a 472/87/1.10

[@marcushert2759]

Who’s 60/67? I’m planning on doing nearly this exact setup with my VP truck. I’m really excited to see how it turns out!

[@MrLiamCooley]

How hard is it to throw a 6.7 crank in? Modify your piston length and let her eat? I wonder how a 6.1L VP truck would be,

[@horsetorquesdiesel]

Not hard. You just machine the pistons down. A 6.7 crank vp44 would be a torque monster!

[@ports787]

Does Myer have a KZbin channel also?

[@Texas12valve]

What do you have to do to run a 6.7 crank?

[@horsetorquesdiesel]

Really just good studs on the factory gasket is sufficient!

[@Tonycallanta1]

@@horsetorquesdiesel thank you for the response!

[@lwilde0422]

Too much compression. Need to reduce compression in your cylinders to clean up that smoke. Hate to say it but with that 6.7 crank you may need a custom domed head or find a way thicker head gasket that works with your fire rings.

[@horsetorquesdiesel]

Just wait we did an injector change and it made a huge difference!

[@lwilde0422]

Excellent! Weird those 5x14 smoked that much. Wrong spray angle?

[@Jc_my_12valve]

Curious how you got 19:1 with that setup. I figured it’s be sitting around 17:1 What was the piston protrusion?

[@horsetorquesdiesel]

We didn’t take the full 80 off the tops

[@CumminsWorks]

Plus the pistons started at over 17:1

[@Jc_my_12valve]

@@CumminsWorks hmmm well I think they took the 80 off mine and some valve reliefs so I was expecting to be around 16.5:1 on mine. But then again I haven’t actually done all the calculations, i don’t even know how 😂

[@CumminsWorks]

@@Jc_my_12valve when you deck the piston you make the bowl smaller. These started out with a 44.5cc bowl, but with a .075 cut off the top now have a 40.5cc bowl. Combine that with the extra displacement, it should be right around 19:1

[@glennhobbs59]

Because 12Valve is all mechanical that’s one good reason
