Double The Horsepower 12 Valve Cummins 

if i didn't know better this looks like a regular tv show except better with out commercials

Again, thank you so much! Husband has this gen (...and others) and it's awesome to understand what he is saying!! Please keep it coming! Thank you, The wife.

That is a beautiful truck, where I live they are just a memory. Back in High school you either dreamed of a 12 valve Cumins or a 7.3 with a turbo.

i like the 12 valve content. would have liked to see more how to on the parts you instead. there isn't very many good how to and detailed videos of performance mods like that. it would help some of use out but great video. great company

With a manual shift, icing on the cake. Awesome!!!!

This was a great video. Exactly the info I was looking for and super well-made.

I was not expecting that much of an increase in torque, that's insane!

The technician made it look easy!

Awesome! I have a 89 Dodge dully with 5.9 Cummins you guys should use on a double the power video

This guy was working so fast I thought he was getting the truck ready for SEMA!

Such a great video, I was wondering what I have to do to my 12V to get around those number! Thank you for breaking it all down and can't wait to do something similar

Verry good video!!! i hope you gonna make same type of video but on different engine like a old gm 6.5

As always todd you guys are awesome with the 12 valve and love your videos. Keep up the good work! All the way from mcalester oklahoma!

Awesome video, Not even 2.5x the torque, not 3, but 3 sounds cooler. That was one clean truck.

That's amazing, great job guys! You made it look easy!

I like your videos! I have a 96 3500 12 valve! I'm new to the diesel world!

That is a beautiful truck for its age, I would consider trading if got my 6.7

P.s I had the AFC live on my other truck and loved it. I still have the truck but it’s been in a crash that took it off the road. I definitely liked the 12 valve 5 speed manual better than the 24v with with the automatic. I’m considering swapping out drive trains.

these guys do good work ! just recieved my afc live but still building my engine so im stoked to put it in

I just bought a ‘94 Dodge 3500 with the 5.9L i6 Turbo Diesel. I would love to do something like this to mine.

Double how much diesel you buy a week with these simple mods. Great video and inspiration for my 12v

Awesome video,y'all are awesome

I would love for you guys to do something to my truck ive watched this video a couple of times just fascinating slowly buying what i need to do mine all at once 😭

Playing the white stripes at 7:25...nice!

I bought 3k gov springs and afc live from you guys, what a difference over stock.

Exactly what I was looking for thanks

Wow huge gains!!!

! did a few of these things to my truck and the biggest problem now is axle wrap when pulling my 5th wheel up a steep long hill...the engine wants to go but the tires are gripping to tight...traction bars/ladder bars are next I guess...

Awesome video guys

Great video! I think imma do a very similar build to my truck, do you know what the fuel mileage was after done installing all the upgrades?

Great video!!

Great vid👍

I have a 97 Newmar front diesel powered by a 6BT and running an Allison 5 speed transmission. Would these upgrades work on my engine?

You should do a video on how to do the fuel timing please. You speed by that part

nice job, i wish i can put DD 6.6 in my gmt330...

I really like the shape of the modded torque curve. To me, that is how a diesel torque curve should look. Low end torque to the max.

Just ran across this video and was curious what the mods you have done in this video would cost and if there are any other mods needed to ensure reliability and durability with the added power.

You guys should do a governor spring installation video

Nice video , whate a huge torque increse

Nice info-video - thanks for that. I did play (~300 hp) with my '97 Cummins, 2WD, 5-speed manual and pulled (too) heavy loads, close to 22K total trailer wight and yes, the truck pulled pretty good but it started to eat tranny's. I saw that you took a heavier clutch disk but haven't heard anything about the NV 4500 and like to know if you suggest to do any changes to the gear box too? Thanks again and take care!

Great video guys!

I will continue watching no harm done I hope just personal opinions I’m curious to see what will come of this I currently drive a Ford F-150 with 300,000 original miles with its original motor who nows I might decide to drop a cummins in it but I thank you for the clear explanation of everything it does make a little more sense my apologies non the less great sounding CUMMINS ...

That torque wrench is next level!

Awesome Job what else could you of done to get to 400hp at wheels and more torque! Change the turbo? Cold you go washer Fluid eject?

Would these kits work in a marine application for example 210 HP 6bt Cummins

How about testing with an aftermarket intake/air filter. As the exhaust has been updated, how about the intake side ?

Anything need to be done with the head gasket or valve springs?

Had Dean opted to purchase a performance turbo, which one would you have recommended with your 400HP kit, and what kind of gains would it bring? Thanks.

hi i've already get the clutch, the afc control and the exhaust, what more i need and how much cost, valves injector and plate?

Question Could you re-gear first to 35 inch tires. I’m not real sure on adding gadgets to make my 97 Ram 4x4 , it’s automatic transmission. I would like to double the horsepower for a stock truck , hauling & towing and occasional cruise night

When you bump the power up that much are head studs needed? Also what about the stock intank pump, does it need upgraded to keep up with the extra fueling?

Can't wait to show this to my teacher

Man I need this to my tuck. Where you guys located. Hard to find a good diesel mechanic in nyc

Interesting video. Just a coup;le of questions. What do you lose in the conversion? Increased Horse Power doesn't come free.Injection timing, has this been set up on an apparatus similar in concept to a Hartridge machine? Original Injector timing has been set to gain max burning of fuel at the moment of injection. Plus all injectors are bench tested and pre-set, equi spray patterns verified and formation of sprays checked inc delivery pressure to each injector.Spray patterns checked and delivery valve closure verified for efficiency and leakage.That plus the spray pattern of the injector determines the efficient generation of power from the cylinder. If the injection phase is early, then the flame travel / ignition will be early which immediately has a slowing effect on the piston travel. With all that in mind, what exactly has been lost, in able to gain the figures which are quoted? I am not slagging it off, just curious.The engine has been rated at a Horse Power for given RPM, increasing the RPM, unless original dyno info is available does not necessarily mean an increase in Brake Horsepower.. Again, I am just curious.

Notice how the real power guys don’t bother with a “cold air intake” or as I call them “hot air intake”

Great video

New subscriber here! I have a 94 second gen 12 Val with a single 74mm turbo 5x14 injectors 4K gov springs and triple disk converter. I have had EVERYTHING built inside my jasper transmission and I mean everything!! Im around 850 HP. I’m getting ready to put a fas flow fuel pump system on it but I want to add an additional turbo I just don’t know witch one to go with. I have had a lot of people tell me different things but just wanted your opinion. Love the videos! Thanks

Great video for possibilities for a 12V, but not super helpful for a diy guy. Would be nice if you did several videos that detailed the steps of what you are doing other than here is what we are going to do and three seconds later, “it’s done” next step.

What's the total price of this package? Which clutch would I need to use for an Eaton 13 or 15 speed?

Would you need to upgrade your clutch if you got a decent turbo and intake system

Do you guy's handle or do any-thing w/the 24v vp-44 trucks? My truck is a 99, 24v/vp44 pump,Nv4500,4wd,3500.thx.

Please do a ve pump truck. I want to see 500 horses with my truck but I don't want to change to the 14mm head on the injection pump

Does the AFC live work on a VE pump?

Just curious. What would the power look like if you didnt change the timing?

what kinda fuel mileage can you expect if you keep the AFC LIVE to a modest level?

No link to the in cab afc fuel adjuster?

In your horsepower doubling series, I think it would be cool to see if it was possible on the older IDI engines like the 6.2 or 6.5

I have compound turbos both on 3 brand first turbo is 72mm and second is 88 non waste gated, I have shields custom fuel plate, o clearance delivery valves, 7x14 injectors, hamilton cam 188-220 cam, valve springs and push rods. P pumped first gen, five speed, with fass fuel system. Should I mess with timing to create more power or consider blow off valves. What can I do to make good power with what I have. Its inner cooled and has 3 inch air intake.

Great Job !

Any advice for getting a wireing harness for a 94 12V ???

Dont even need to do any kf thoes upgrades to add much more power. Just tweak to p pump and there ya go more power.

Tips on how to get the tamper screw out??

Did it act like it had a rev limiter ? Blue/white smoke? Mine acts this way won't rev over 2000 rpm.

How much do you charge to do that I have the same engine on my 95 ford f800

I wish yall would do a video on doubling horsepower on a first gen ve pump😂

Make a video to go more in depth on the installs please

I have a fummins F450 self loader tow truck What can I do to a stock 12 valve with p pump to make enough power to get this up to 300-400 HP range like the 6.0 powerstroke that was in the truck originally without smoking up the street but still get out of its own way. I’m also running the ford automatic 5R110 transmission. Truck with me in it is 11,000 lbs then towing cars all day so I’m always heavy

Total price of install would be nice to know, even if its just an estimate or ballpark.

Thanks for the excellent video! I have used two of those clutches from South Bend and they are a bit stiff on the pedal especially for all the city driving I do. If you drop down to the 400 hp clutch it's a softer and more stock like pedal. I'm also curious what was the boost numbers you needed to achieve that horsepower/torque level. I've had my share of blown head gaskets on stock turbos and head studs. I've blown 2 head gaskets at 40 PSI on stock head bolts and two at 40 PSI with head studs. 17* timing. Needless to say I made some upgrades. 🙂

So How Much Boost Did It Make Stock And Modified? That's some vital info that was left out!! Why??

Hi I would like to know where I can find and purchase your product I live in Québec and can’t find canadian site with pdd stuff

I have a bone stock 1997 , 12 valve, automatic . Truck is one owner with 106k miles. I think I need to do the exact thing to it you just did to this truck. How much time in shop to make these upgrades.?

How do the runs compare at the same rpm?

That was a 25 year old truck. How much did it cost to get that extra HP? What if you have the stock auto transmission for 95? Can it support the extra power?

What about the turbo? Are you running stock boost? Can the stock turbo make/handle 400hp?

That's all well and good but HOW MUCH DOES IT COST?

I know this video is a little old. But I'm curious on how injectors are measured. On the website, the injector set in this video is rated at 40hp over stock. How were you able to push out 150 horsepower over stock with these injectors?

How much would this day cost minus the supplies.labor and dyno only?

Where can I get this set up for my truck?

This is going to sound weird, but is there a way to reset my AFC housing to factory-ish settings? I recently bought a 1997 12 valve and the dude said the pump "has been turned up a bit" referring to the smoke screw and the star wheel and the timing moved to 15.5 degrees. He doesn't know anything else about the pump, someone else did the work. Like I said, can I reset these changes so that I can redo everything myself the way I want it done? Thanks!

does any know how much all this work would cost nowadays? thanks for any info.

Was a new lift pump installed?

Great video 👍💥Power💥

Im new at Diesel Cummins. Just inharited a 1st Gen Cummins Diesel Dodge Ram 250 turbo and my question ❓❓. Is do you have package deal as shown on video for my 1st gen cummins turbo diesel?

very nice video thank yu

Thank you for this video; great information. What would be the cost these days for all the upgrades (minus labor cost) you show in this video to achieve the power numbers on the 12-valve Cummins?

Subscribed and liked 👍🏽👍🏽

What's the best turbo for that combo

So. Where are you located. I have a 1984 dodge ram charger. I need some upgrades just like this

nice to see the pilot bushing was swapped for a pilot bearing for the input shaft of the transmission, that was a killer for the Getrag 360 on the older trucks. Do all nv4500 trucks have that pilot bearing or was that just a southbend thing?
