Lol those 2 r the only ones that fascinate me as well. Very intelligent couple of guys and I've learned alot about so much from them throughout my build so far
I’ve got to put head gaskets on my lb7, it has 280,000 miles, should I spend the $700 extra to put in a new cp3 pump while I’m in there or spend the $700 on a good lift pump? Wish I could afford both but can’t, I’m also not having any problems with the existing cp3 pump, it’s just getting old. Thanks for any advice.
chris kriewall Chris, yup, it’s stock. I’ve never done anything to the computer and never pulled much with it, just packing the family around on interstates for 280,000 miles. I love that truck, my kids grew up riding around in it for the past 15 years. Had injectors put in it at 198,000 miles by a factory recall but that’s about it.
My lb7 has 370k on it towing a 34’ enclosed trailer a few times per month. It has a built trans, lift pump, custom tuning and have never had a single issue. Change the fluids and do basic maintenance, these duramax’s are fantastic.
Lambda is easy to work with on a computer controlled engine that consistently changes fuel delivery in relation to air intake charge. However, older mechanically injected Diesels unfortunately can't change fuel timing and delivery on the fly, the fuel that is directly proportional to boost pressurized intake charge will be over fueling at idle or half throttle input. So now the burning question is if an older non emissions/lightly emissions regulated Diesel can be a legal swap into a classic vehicle, and still pass an emissions test. I've heard hydrogen injection can vastly improve emissions, I have no idea if they'll allow you to pass a state emissions test using it though.
By very definition you can't overfuel on idle - if you did you wouldn't be at idle anymore, the engine would accelerate. Yes it's possible to run smokefree with a mechanical diesel if the boost compensator is adjusted correctly. But for max performance it should make just a tiny bit of smoke when you press the pedal quickly. It should restrict maximum fuel off boost and slowly increase as boost rises
Hello, I have a question which i cant find the answer anywhere and i hope you could help me. How does the catalytic converter on a Diesel car, (Diesel oxi cat) work efficient with a λ way to lean ? To get a catalytic converter to work we need a λ from 0.997 to 1.003, so how does it work? Thanks
Hi all. Can someone answer a question please. I found a afr kit for my car that matches my gauges. It is sold as a diesel afr kit. Are the wideband kits interchangeable between gas or diesel? I cant find any information anywhere
Sorry, But You're NEVER going to convince me that DPF, EGR, SCR, CAT and DEF is "BETTER" for these Diesel engine's. I don't care what or who's tuning you put into them! In the end, a Deleted Diesel Engine (Tuned or Not) will easily go 500K+ if properly maintained..... You will be hard pressed to find that with all this "Crap" bolted on them. (Sorry, Rant over) Thanks for the video's though, Nick.
That's cool. Just to be clear we never said the emissions equipment is better for diesel trucks, we just have accepted that they exist and we have to work with them.
@@Duramaxtuner I know I wasnt trying to be mean or anything. I just dont really see why all the emissions stuff is needed. Diesels produce much less pollution than a gas job. My 6.5 is a different story because that's an older truck.
Great question! We did a really in depth review of air density with Gale Banks on the Diesel Performance Podcast. Maybe we can re-hash the subject again in the future. traffic.libsyn.com/dieselperformancepodcast/swirl_2.mp3
It is surprising to hear that. All of our speakers are playing back clean audio on this video. Have you by chance tried to watch on a different device? (we use Sennheiser lavalier microphones which generally pic up really good audio).
While the DOC can get plugged, our experience has been more issues with the DPF and not the DOC. This video is a little dry but it explains these 2 components very well. ua-cam.com/video/4DTR4uze2Ig/v-deo.html
WHILE IN EUROPE PEOPLE BUY SMALL CARS TO DO LESS EMISSIONS - AMERICANS THINKS OF WAYS HOW TO COUNTERACT THAT AND MAKE GAMES WITH SUV TO PULL TRACTORS JUST TO PUT AS MUCH POLLUTION AS THEY CAN. TYPICAL AMERICANS -LIVE ONLY IN THE PRESENT AND NEVER THINKS 2 DAYS AHEAD.
Other than gale banks Nick is the only other man that turns me on talkin about these diesels.
americans understand nothing about diesels so.... nobody talks :) gasoline cars are simple like paper plane

Is there a diesel specific AFR Gauge system? Seems like the majority range from 10-20:1, Diesels go way leaner under lighter loads/cruise right?
plz answer what is the best afr for tuned diesel
18:1

Yes get that cp3 to save everything now.then do the lift pump later.best case

Does your lb7 have a tune on it? Just curious if it's stock and has head gasket failure? Thanks

Have you guys done a video on what’s the best fuel additive to use for LB7. If not what would you recommend
We are not real big on additives. A lot of buzz out there right now about Hot Shot Secrets. In the winter, most of us run Howe's.

I’m back !! Bang💥Bang💥
Why are these insights vids so short?
We try to provide a mix of run times for our videos.
Tell Paul what you want!
So... engines run hot from running RICH (while under load)
no Only diesels run hot from running rich. Gasoline cars are running hot when they run to lean.
Will doing an egt? Delete make my lb7 last longer?
Do you mean egr?
Lb7s don’t have egr, unless it’s a California version

@@Duramaxtuner Well...... you could always just take all that shit off and throw it on the floor like most people do. Lol
@@shawnhenaman6448 Due to EPA restrictions that is not an option for us.

What about air density? ;)
You already have mass airflow.
Great question! We did a really in depth review of air density with Gale Banks on the Diesel Performance Podcast. Maybe we can re-hash the subject again in the future. traffic.libsyn.com/dieselperformancepodcast/swirl_2.mp3
Can you please get a decent microphone. Bad video is easy to overlook. Bad audio makes it hard to watch.

L5P at 3mins in to the video.......I’m catching these hints.
face plug the DOC not the DPF

Cut the dpf out problem solving
Even if you have a pre-emissions truck, understanding how Air to Fuel Ratios impact your power, performance and MPGs is valuable knowledge.
Cool beans
Lambda lambda lambda limit
omega mu!
When diesel is burning rich it makes less heat then burning clean.
wrong more fuel in a diesel means hotter egts
