Nick, your testing and knowledge on the Duramax platform, not to mention transparency, is the reason why my last 3 trucks have been tuned by you! I love this stuff, knowledge is power!!
Awesome video. Data is awesome. I dont own nor do I plan on owning a duramax, but I love your videos because you are thorough. Had you done oil analysis on the motor during all these incremental changes? Curious if that would have told any of the story. Also curious what IAT's were and any sort of change in those as the power increased.
what about an LML with 100 overs and 10mm cp3. how much power can it safely live at? thinking of going that route and either stealth 67 or 64. would a 67 blow up my stock lml
I have the same question I’ve got a 68/73 dual sportsman’s but I’ve heard and seen people run those trucks 800-900 hp with stock bottom end I think the lml has stronger internals bottom end than previous models I may be wrong but you see a lot of lbz failed over 700 and a lot of people running 700-800 on lml with no issues
Was this a fresh engine when you started dyno testing with it? Or was it a used engine out of a truck and if so, how many miles where on it before it was used for dyno tested. Just curious. Great video Nick.
It was a used engine. Freshened up the heads and fuel system. If I said I knew how many miles were on the bottom end I'd be lying. Salvage yard stuff..
Quickly melting a hole thru the piston at 700hp likely means your runs at 600hp would have a the same issue if held for more than a short dyno run. Hard to consider that "safe" at all.
I have been to 7 so called diesel mechanics, my 06 lbz Trans and engine run hot only when towing. I changed out the thermostats , coolant, fan clutch. Some say it's the heads, others the water pump then others say egr valve and cooler or radiator. I have clean the stacks and all is stock. I don't trust parts changes it can become very expensive! The problem started in 2021 with 145k miles on it, I was pulling my 20 foot travel trailer which weighs 7k driving west on I - 70 in a bad head wind driving 70 mph for 3 hours all temps almost went red and oil pressure dropped and so did rpm. Everything is great not towing even with the bed full of rock. Help me please!!!

Curious how much lambda changes with the oval bowl. I would assume they would be a lot more smokey
I think Banks cautioned about turbine drive pressure being much higher than boost pressure.
It’s all about application. Old Banks was running a giant 8085 single, not something you’d want to drive on the street.
@@jamescharron8550yes but a good vgt shouldnt be 2x boost
Nick, have you guys done any testing with the "Speed of Air" pistons?

@ thats good to hear i might be going 67mm and sending it around 750hp on stock engine
Above 500 horse pwr...with all stock components and a tuner, slightly larger turbo...how many miles would you expect to get from the lbz.

Any details to share about fuel quality, like the cetane number?
No, just pump #2

We're all welcome to our opinions. I'm certainly not going to twist your arm to run 600HP continuous on your engine if you're not comfortable.
Aftermarket pistons would’ve helped
That was exactly what I was thinking. Those are the South Korean pistons?
Probably..

1650 spicy!!
Those look like the stock pistons!
It was a stock bottom end, so yes -the pistons were factory stock.
You killed a Duramax before Banks actually did it.
The trick is to not overthink it.
Banks makes like 300 hp 😂
Little but more methodical about it
@@HSKFabricationswhat?
@Eric_V410 What? Banks goal isn't to make power. It's to sell carb and epa compliant gimmicks.
So that’s like 500whp 😂 buy a Cummins if you want to make power
2019 L5p banks smog legal in CA. 501 hp 1010 ft lbs at rear tires.
9 min of talking what a waste of time
