Stock cummins turbo boost pressure
https://www.projectcummins.com This is how I added 7 psi to my stock turbo with the AFE wastegate Blade Runner sires #46-60059. If I had to do it again I would of done it when I would have more This is a short video of the boost and drive pressure on my truck. The top guage is booost, and the bottom on is drive press. 6.7 cummins boost and drive pressure Ben Vail. Cummins 6.7L The turbo is designed to reach peak boost pressure quickly, while creating minimal exhaust back-pressure in order to drive the turbine wheel. Performance turbos differ from stock in a number of ways: most have larger housings (which increase air-flow), larger wastegates (that prevent premature "blow-open"), and some "ball bearing turbos" replace the bushing with ball bearings providing quicker "spool-up". Those trucks in stock form (no programmer or boost fooler/elbow) should only hit about 17 to 21 psi boost. And Woods is correct, with aftermarket performance modifications with a stock head gasket you should try and stay below 40psi. I will also stress that fuel pressure if of utmost importance with these trucks. The computer will reduce the fuel rate (cut back the throttle - it is throttle by wire anyway!) when the boost exceeds 21 psi on 215hp and 235hp engines. From Cummins: Cummins builds engines with the proper combination of turbocharger, pistons, timing,

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. The map sensor on mine reads some where around 14.6 at idle which is atmospheric pressure. At full boost it reads 37.4 and stays there as long as I keep on the throttle. So about 23psi is what it will do. I've never seen it spike above 37.4. Lift pump pressure is only about 10 psi. Cummins actually does not put a spec on it. They put a spec on how much volume the pump is putting out. Should be more that 500ml in 30 seconds. What is the best way to increase boost and what can the stock turbo withstand? Assuming everything else enginewise is stock as well. Also, I may or may not want to blow some smoke and was wondering how one does that? Last, but not least, I here a lot of other Cummins with loud blow off/or what sounds like a jet engine shutting down Measured with Autometer boost gauge 26 psi stock on my 03 and 31 psi on my 05 ultra gauge on my 03 & 05 would read boost pressure to match mechanical gauge. My Cummins trucks are a totally different beast long stroke I6 designed for longevity and torque. Pre emissions for sure as well. No external EGR. If the filter minder is in good shape it's time to verify appropriate boost pressure. LB7- Stock turbo trucks should make 26psi with Jack tuning and 29-31 with king tuning as measured on an analog gauge. Do not trust any electronic boost gauge that uses the factory MAP sensor or OBD2 plug. They're only good to 22 psi. The HY35 turbo is limited to 30-32 PSI of boost. As for the programmer it will kill off the P0234 error code because of the programmer ability to boost fool. So the ECM never sees above 20 PSI so the error code is never tripped.
12 Valve 2nd Gen Dodge Cummins 94-98 - how much boost w/stock turbo lbs of boost outa my old stocker but u gotta be carfeul way to much drive pressure.
All depends on the situation but usually the waste gate on them open around 28 to 30 psi and they can hold boost at 25 psi for the most part. Cruising your looking around 6 to 8 psi maybe 10 depending how fast your going. Hope this helps not sure exactly what your asking. Although the stock turbo may only be making 40 psi of boost, it could be seeing 85 psi of drive. This means 45 psi is pushing on the thrust bearing. With the thrust bearing riding on a thin layer of oil, the pressure difference can force the oil out from between it and the shaft, leading to bearing-to-shaft The amount of pressure a turbo can generate is measured in pounds per square inch above atmospheric pressure. So a turbocharged engine with 15 pounds of boost would be moving roughly twice the air of a naturally aspirated engine, and all things being equal, would make roughly twice the power. https://www.projectcummins.com This is how I added 7 psi to my stock turbo with the AFE wastegate Blade Runner sires #46-60059.

Most cars can handle another 3-5psi boost pressure without extra mods. All you need is a boost gauge and manual boost controller. I'm talking about older turbo
Even on a stock truck you can easily gain 5-8psi of boost pressure to help cool your On 2007.5-2015 6.7L Cummins, the turbo uses electronically controlled In this instance no modifications to your turbo will be necessary. Stock 04.5-07 trucks typically spike up to 32psi of boost pressure. With the Boost Fooler you will 1 Mar 2019 This increase in pressure builds boost faster and harder - once you of your stock turbo, but give you increased performance and longevity. Garrett® Boost Adviser is a tool developed to perform a turbo match quickly and and address durability issues with the stock turbo at higher boost pressures Most cars can handle another 3-5psi boost pressure without extra mods.
