Power Jet Fuel Injector Development | 12v Cummins Dyno Test 

Love that we're still getting r&d and improvements for the 12 valve all these years later

Let's see the actual fuel economy with upgraded injectors

Now you’re speaking my language! Anxious to see the fuel economy results!

I'd really like to see what kind of real world fuel mileage you get with those new injectors.

Viideos like this showing testing and data are the best in my opinion.

It's awesome to see real research and development 🤘

Great content! Some of the most objective and best diesel content I’ve seen! Keep it up PD Diesel guys!! 👍🇺🇸👍🇺🇸

You guys are really going to next level in what someone can do with these trucks.

Very cool to see new stuff is the way. Look forward to putting some things like this on my 97

Awesome videos you are putting out about the second gens. Thank you. Cant wait to see and watch more VP dynos.

Wow very manageable egt not even past 1250! Very impressive. Great video thanks guys!

Love your still learning and sharing this info to....... please keep posting...

I can't wait to see some more testing with these injectors, that towing run with the new injectors looked real clean. The smoke was really low, more or less a haze the whole run.

Amazing, hopefully ready when I rebuild my 98 12v in 23 God willing.

Guys this is great video the tests between one component and another is really interesting it's real world testing not just burning rubber in my opinion doesn't prove anything ( but your local tire dealer loves them LOL ) PLEASE keep the tech videos coming As always take care stay safe and God bless you all 🙋‍♂️ 🇬🇧

Nice one guys ! Looks like a decent set of injectors 👍🏻

I like to see videos like this, very interesting and i like how you presented the testing and analysis! And if these end up being your level 2 version, I'm interested to see what the level 1 version numbers are if you bring something like these to production.

Love the info. And this is exactly what alot of people need now days. Best of both worlds power and fuel economy.

very cool info guys! can't wait to see more!

Hell Yea!!! This is exactly what I need for my shorty!!!! Keep it up guys and ill be waiting for them!

Looking at upgrading my injectors. Awesome info

DAMN!!! I just bought injectors....now Ima hafta buy some more :)

So cool to see the difference in egt’s, for me towing power and efficiency is the most important thing. My 09 has stock fuel and air but I am tempted to see what I could do with some custom cut nozzle’s.

Very well done, keep these coming👍😎 We all enjoy "Mur", and you two are good together.

You guys are badass, thank you!!! NC

I love the video this is thing I'd like to see before I buy a product!!! I definitely would a set when they come out

love the tech vids.

Hey guys , I am loca to Cedar , bought a swx362 in April for my 1998.5 and the only part of my truck I don't have info on is injectors . Truck gets 14-16 at best right now , want to get a good compliment injector and have the head flowed and a custom tune with the quadzilla I got . My other Cummins was 20 all day long mpg ... Hoping to get closer to that as build power as low as possible for towing.

Seeing how much that 180 pump can make on stock DVs almost makes me reconsider a 13mm pump from you guys for my 24 valve... almost

Yep. Keep the data coming. Muhr you doin good on camera. Todd please revisit the claw(respect to your boy. Lol). Trying to do the hotrod tow rig vortex of money thing on my 06 qaud. Trying to get it right.

I was about to pull the trigger on your 5x12s. I think you convinced me to get these. Love the real world dyno to help me make informed choices.

Yes good stuff. I can't do what you do that's why I always check out your channel. Let's me know what I can do that really works. So it saves me time and money wish I had a smart phone when I started my 95 12 valve

The information I learned is awesome thanks

Can't wait for these injectors! I have 5x14 injectors and they are hot and Smokey in a ve12v so I think smaller is the answer

Great content When are these hitting the market?

Hello from Sacramento CA. 1997 2500 4x4 cummins dodge

I have your 75hp VP44 injectors in my motorhome with your towing compounds on it. Would love to see if a more efficient injector at that power level comes available

When these come out, you've got a customer! I bought ol' Lazerus to WORK, not be a toy & these seem the best of both worlds! I'm not a tree hugging Green New Deal clown by any means, but more horsepower, less smoke, better fuel economy is an all around environmental win in my book!

Exciting stuff. I have a vp44 truck that I run 7x10s built by Weston Shuppe. I like his injectors simply because they run cooler, more power and less smoky. This truck is used for deliveries, running about 70 to 80k miles a year. If y'all make a set of these, comparable to 7x10s, I'd buy them to test them and see how they do. Mpg is important. At the end of the day, the better it is, the more money in my pocket.

would love to see some fuel economy optimized nozzles for the 5.9/6.7 common rail engines

DDP. Tell ‘em where it’s at! Lenny is the man

yes i like to see more those test videos! and after hours storys :D

Awesome video 👍🏻

This is great. Looks like a year in... Im pretty close to getting some. Looking for new, less smoke, and EGT. I think this is all around a great choice.

Love data all I can get

I like doing and seeing research done like this I do the same ony reloading ways to improve many different things.

muy interesante quiero mas ...

Are you planning on having this available for the 6.0 powerstroke

Yes I like day driver maybe test some 24 valves if you need one to test on I have 2001

Makes me miss my vp44 truck. With an adrenaline tuner and an Hx super 9 I ordered from y’all I was averaging 18 mpg. That’s better than my deleted LML I have now. 🤦🏼‍♂️

Will you be developing anything like this for the common rail trucks?

Really enjoy this content always watching your guys tech videos. I'm curious though I currently have a set of pdd 5x12s and was thinking about going a little bigger would you be able to compare these to 5x12s to see the power level difference? A drop in egts would be nice as well

This is what I am looking for……we have a stock 96 5 speed packing a camper that is starting to show her age. Looking to keep good fuel economy but increase the torque a little to better make the 3 rd gear 4th gear jump easier. There are lots of people looking to update there trucks while keeping the economy up.

Are you selling yet ? I am wanting to pull the trigger on a bundle of stuff for my Fummins build and these seem like a good choice . I need to call yall and talk about a couple things I have questions about .

Hell yes baby

Love the videos wish you had the power jet injectors for the 24v with a 7100 pump.

What happened to that 24v video series yall were workin on?

Changing the nozzle or the whole injector witch is better result? What about 24v???

If you happen to take these injectors back out, I have a 1998 automatic with AFC Live that they would fit nicely in 😁

As I’m building my Cummins powered 4x4 Ford Econoline van for long trips this is the video series I’ve been waiting for!!! I bought your 400hp kit(still in the box) I believe that has 7x.009 injectors, will you be developing a comparable injector that is more efficient?

DLC coating can add to the efficiency!

Love everything I'm seeing about these Power Jet injectors.. are you guys planning on cutting this nozzle geometry into a 24V injector nozzle/body? I have a 180hp Ppump on my 1998.5 24V with PDD 362SX-E, PDD 7x0.0085 injectors set at p-pump pressure, and 055 DV's... love the power but looking for a little bit more efficiency and little less smoke.

Was this test carried out with stock timing? If so it would be interesting to see the same test with a mild timing advance 👍🏽 love the videos keep um coming.

Need to try some DLC coating.

EGT looked pretty good! Anything under 1250 in my book is pretty safe.

Is the truck running stock timing?

His reaction gave it away...lol

Great video! Let us know when we can buy them!

Early bird gets the cummins content

Please more for mileage

Id also like to see whats available for the 24V 5.9 in the way of similar injectors.

Ok I have a similar set up. 97 12v 5sp 2wd that I drive constantly on the highway. I have a turbo out of Texas and just the free mods done. I would love to be a real world Guinea pig. I am putting 600-1000 miles per week on it

Which builder are you partnered with?

I’d do some testing for ya with my 12 valve! 😄

DDP injectors come to PDD :-) those 5x.011 seemed pretty dirty. Would be good to see them against some marine 370s which are 5x.012. I don’t recall the 370s hazing when up on full boost like those 5x.011 were.

I’d buy a set of these but I was trying to pay attention to more of the (driving) rpm range like 15-2500/2800…

I’d be interested to learn how they compare to the 5 x 18’s that I’m currently running.

I know you guys have been testing these out for a while. Do you have any more information on how these are gonna do as far a fuel mileage goes?

Are you guys going to work on fuel mileage injectors for 1990-1993 12v? I'm currently getting 18-20 on my 92 12v which is bone stock except for a 4" turbo back exhaust. I would like to improve my fuel efficiency and possibly get a little more power.

Already subbed but i like seeing concrete data. Seat of the pants assumtions and claims have become annoying to me. I like seeing facts. Also i like seeing that you guys are deciding to take the road less traveled and try to make real changes instead of doing the same crap everyone is an throwing out some unsupported claim. I look forward to seeing more progress on these injectors.

So when can I buy a set?

That poor pitbike by the exhaust hose😂

Great video, but can you give an estimated fuel economy improvement?

So is Dynomite diesel helping you

Are these PowerJet injectors SAC or VCO? Are the stage 1 a good fit for a bone stock truck? Looking for mpg, clean burning, an maybe a little more power. I thought I had decided on VCO 5x0.011 sticks, now I wonder if these will be better for me… 🤷‍♂️

It would be awesome if you guys tested intake horns just to see if they are a waste of money

Bring on the data!

What I have been informed is most of the injectors are pre set to 1800rmp before they fully come on and the 5.9 love to chuck along at 1700 all day long sipping fuel. And most of the injectors are for marine/GPU's (ground power unit) and some injectors come on way higher in the RPM but I am sure the pump pressure also plays a important role and higher pressure can give better pattern and atomization leading to better, faster, more complete burn and cooler block temperatures. But to high and instant flame thrower with valves not in the volume metric efficiency so bad performance. So it is a fine line and pattern shaped/placement is critical and available fuel in a critical very short time. That is a lot of variables to juggle and fine the sweet spot. I am wanting a sequel turbos(lower EGT's) and better fuel efficiency/torque and peddle responce(less turbo lag / more air/boost) and you did address the intake and exhaust flow in this test. What we were not give was the flow rate, pattern/atomization and air to fuel ratio at RPM levels. And timing adjustments will have a direct effect on tests, so for what you need is a clear cylinder to see and adjust pump pressure versus atomization. Now my second concern is how long will it take to recover the cost of the new and improved injectors? That is were you know if the product model is a viable solution for your customers.

R&D is fun

So are these nozzles going to be available on their own? I was planning to build some of your 5x.012 nozzles on the spare set of stock injectors I have, but these seem like they may be the perfect setup to max out my first gen's pump with an SXE turbo

🤩🤩

I don’t see the 67/67 turbo for sale on your website in the 12 valve section. Is it more of a common rail turbo?

Wasn’t that the premise of the video to find out what kind of economy and mileage you could get out of it and not how much power because as you stated fuel cost was so high I mean it’s a great video but

So my question is can you do it for idi? As in GM6.5 turbo? Cheers

👍

Sounds like someone has been talking to Leeny and all his fancy new equipment.

Do you think you will come out with a set for ve pumps?

I need a set for my truck or better yet yall need to check my 24v out lol

I thot black smoke was unburned fuel how more smoke more efficient? It seems like it’s to much fuel on the full power the rest didn’t smoke to much. I also thought more un burned fuel made egt hotter?

Vp44 guy here. What are the odds of a set for us?
