Danger Zone: 570+ rwhp or 40+ psi boost ’07.5-present 6.7L common-rail: 480 to 530rwhp With a new-and-improved injection system, increased bore and added stroke over the 5.9L, the 6.7L Cummins was destined to be a torque monster, but its use of a variable geometry Holset HE351VE turned it into a real earth-mover.

How much boost does a Turbo add to power?
For the most part boost and power in psds and others go hand and hand. Okay partly true what is being explained, I will make this simple most turbos can make 30 psi of boost but the CFM or airflow is not there, also heat is a big variable you can add pressure increasing heat from over working which can cause a loss in power.
What is the boost on a 2007 Dodge diesel diesel?
I am glad I make you laugh, but I just switch from 2007 Dodge Diesel (for last 15 years I had Dodges ) where stock boost was 22 PSI and just adding Quadzilla controller rise the boost to 32 PSI when towing. That way sorry for maybe stupid question, but not really know to much about new Powerstrokes engines and turbos use on them.
How much HP can you tune a stock truck for?
You can tune the truck for modest power to upwards of 150hp on the stock fuel system, but it runs out of air and fuel shortly after 500rwhp. Why do you want to punch the boost up?
How much boost does a LML Turbo put out?
Still, as long as peak boost is limited to 35 psi, the LML turbo is just as stout as its predecessors. Want to fix some of the OEM problems with you diesel truck?
How much boost can a stock 6.7 Cummins handle?
When pushed to its absolute limit, the OEM fuel system on the 6.7L Cummins (lift pump, CP3, injectors) can support as much as 530rwhp and roughly 550rwhp with a turbo upgrade.
How much power does a stock 6.7 Cummins make?
The new high-output engine boasts 420 hp and 1,075 lb-ft of best-in-class torque. For RAM 2500 and 3500 (equipped with a 68RFE Auto) HP and torque have increased to 370 hp and 850 lb-ft to provide the right power for these models. Your vehicle is equipped with an engine oil change indicator system.
How much HP does a stock 6.7 Cummins have?
The new 2019 Ram 2500 and Ram 3500 trucks equipped with the high output engine produce 400 horsepower and 1,000 lb/ft of torque. Here is our horsepower/torque chart to make it easy for you!
How can I make my 6.7 Cummins faster?
Tunes primarily improve power by increasing turbo boost levels. When running higher boost levels bringing more air into the engine is necessary to reduce stress on the turbo and improve its ability to spool quickly. Therefore, we recommend going with a performance intake system to increase airflow into the engine.
What is the life expectancy of a 6.7 Cummins?
The life expectancy of a 6.7 Cummins engine generally ranges between 250,000 and 350,000 miles. There's more to the longevity of a Cummins engine than its mileage, though. The mileage of a 6.7 Cummins will specifically depend on the kind of driving you do, not to mention the state of your truck.
What should I upgrade on 6.7 Cummins?

What year Cummins is best?
1994-1998 2500 & 3500 As far as performance potential goes, it doesn't get any better than the mechanical P7100 equipped versions of the 12-valve 5.9L Cummins. They're simple, rock-solid reliable, and can easily tick off a half a million miles if properly maintained.
What makes a Cummins High Output?
The standard output Cummins provides peak torque at 1,700 rpm, while the High Output version will do so at 1,356 rpm. High Output engines benefit from a heavy-duty Aisin six-speed automatic with a 3.75 first gear, whereas the standard Cummins uses an FCA-built six-speed auto box (68RFE) with a 3.23 first gear.
What mm turbo is on a 6.7 Cummins?
2013 - 2018 6.7 Cummins Turbo It has an upgraded 63.5mm billet compressor designed to provide greater airflow and to lower exhaust gas temperatures.
What do I need to delete my 6.7 Cummins?
If you do need or want to delete your DPF system, there are a few components. First, you will need a DPF delete kit. Second, you will need a proper DPF delete tune. While deleting these exhaust components mostly just requires bolting up some new piping, keep in mind that you won't be able to find a shop to do it.
Does a 6.7 Cummins have a lift pump?
The factory fuel system on your 6.7L Dodge Cummins consists of your underbed fuel tank, fuel or lift pump, high pressure CP3 injection pump, and electronically controlled injectors (simplistically put).
Can you tune a diesel without deleting it?
Registered. Simple answer yes, but your powertrain warranty is for the most part toast once you load a tune. Considering a vast majority of issues with these trucks are related to the emissions components just be prepared to shell out for repairs if needed.
A Word on Stock Turbo Failure
In most stock turbo applications, drive pressure will become a problem long before boost pressure does. When drive pressure is considerably higher than boost pressure (such as a 2:1 ratio), the thrust bearing is forced to absorb the pressure difference. Although the stock turbo may only be making 40 psi of boost, it could be seeing 85 psi of drive.
Power Stroke
Thanks to being wastegated (bleeding off potentially harmful, excess drive pressure), the turbo used on ’99.5-’03 7.3L Super Duty engines, the Garrett GTP38, is capable of surviving slightly more horsepower than the non-wastegated unit found on ’94.5-’97 mills (the Garrett TP38).
Cummins
The HX35 is tough as nails. It can handle twice the boost it was intended to make from the factory and then some, long-term. It’s also been used as the high-pressure (manifold) charger in various compound turbo arrangements over the years. Simply put, it can handle plenty of abuse (40 psi of boost and high drive).
Duramax
Equipped with a fixed geometry turbo, the valley-located charger used on the first-generation (LB7) 6.6L Duramax was manufactured by IHI. Called the RHG6, it sports a 60mm compressor wheel (inducer), a 68mm turbine wheel (exducer) and features a wastegate.
Can Cummins be paired with 18*?
The cummins will be fine with the 18* of timing. Of course as timing goes up, so does cylinder pressure. If you start stuffing the cylinders full of other stuff, such as water/meth, then the pressures will get high enough to possibly lift the head. Mark Chapple, the owner of TST, is a retired engineer for Cummins.
Do turbos have more heat?
Just remember, for every degree of HEAT you put into the intake, you get another degree on the exhaust side too.#N#Turbos that are operated outside of their "efficiency maps" are making more HEAT than airflow. Hotter air = more boost, but less air flow.
