BOOST vs. DRIVE PRESSURE

[@zacharyruble6368]

Thank you for taking the time making video, great info! Always learn something.

[@DynomiteDieselTV]

Glad it was helpful!

Great video Lenny. Very informative and insightful.

Glad it was helpful!

[@DieselPowerProducts]

Fantastic video dudes. Nice work!!

[@DynomiteDieselTV]

Thanks a ton!

[@projectrollingthunder9049]

Grate video really well explained. I have a adjustable waste gate and was surprised when messing about with it how after the sweet spot those egt spirals and the truck actually looses power

[@DynomiteDieselTV]

Glad it helped!

Turbos. I am going with one I bought from DAP. I am not going for crazy HP numbers. 400 at the flywheel is is fine. Great video BTW. One of Lenny's videos on how they make injectors got my interest. I already had a set of +50hp not installed from someone else. I ordered a set of Stage III nozzles from DDP to swap in. After watching another injector video by Lenny I wish I just ordered a set of their Stage III injectors. I may do that still.

Great video

Awesome video man 👍🏻

[@DynomiteDieselTV]

Thanks! 👍

[@parkerdanielleffew]

Are you able to get an accurate drive pressure reading using the factory EBP and MAP?

[@johnnystanley4469]

Great content thanks for the info.

Here some perimeters 450hp mantifold turbo Spool around 1200rpm T3 Dual wastegated T3 Qsv (quick spool valve) Compound setup, so the mantifold turbine will need to suport 1200hp overall What's your opinion for the mantifold turbo choice. Im leaning towards a gtw3684r with a custom turbine housing But then i saw the massive borgwarner low drive 93mm turbine. And was concidering a custom turbo with a larger turbine or rather, higher flowing turbine via clipped, narrower hub, even the hub less ( all blade turbine) ive seen. Goal is obviously efficiency. I don't want to buy 5 turbos to settle on something, id rather pay extra fit a custom turbo that's actually right. Bedsheets lets face it, these turbos are not specific to a build

[@matt1560]

Where do you hook up your drive pressure line to

[@DynomiteDieselTV]

One end goes in to the exhaust manifold, with a copper tube coil. The other end goes to some sort of boost gauge.

[@ShainAndrews]

Watch it again.

[@matt1560]

Thanks for all yall videos it really helps a lot

[@DynomiteDieselTV]

No Problem, that's why we're here!

[@benwhittaker8630]

Will having the EMP gauge mounted near the base of the turbine housing, just after the flange, cause readings to skew at all?

[@DynomiteDieselTV]

Mounting it in the turbine housing, opposed to the manifold? No, it should not affect your readings.

[@finlay230]

excellent vid !!!

[@hallasnackbar1865]

If my truck is running clean and ego's stay below 1100 do I need to worry about drive pressure?

[@garrisonsmith9784]

what about VGT turbos lets say in a duramax? as far a drive pressure / boost ratio?

[@DynomiteDieselTV]

If it doesn't have compounds on it, I wouldn't be concerned with it.

[@birdshot3087]

Can you run compounds if they both have wategates? Sxe369 paired with a hx35w

[@Dirt18]

Will drive pressure affect turbo surge? My truck starts a surge/swishing noise when it hits lock up. It’s an 04 5.9 Cummins that has a bd super b special that is a 64.5 compressor and a .80 housing. Not real sure of the turbine wheel size

[@DynomiteDieselTV]

Yes, and No.... There is no short, and simple, answer to your question. The biggest issue that we've seen, for that application, is actually a result of the ratios in the transmission and too large of an RPM drop causing the surge.

[@Dirt18]

@@DynomiteDieselTV thanks for the reply. Really enjoy your videos

[@DynomiteDieselTV]

We're glad you're enjoying them!

[@JohnDoe-ud2cc]

Im doing a compound kit on my 12v right now. Do I wastegate the little turbo??? What keeps the little turbo from over spooling?

[@daviddroescher]

1 of 2 ways to keep the high pressure turbo from overspending. 1 size it too big to over speed 2 wg inturnal or external.

[@horsewhispererr]

Well dang, now I need to check my system. I have k27 over a 369 on a vp truck with your 125hp injectors and I can get 1400egt real easy... wonder if the 27 is working too hard. Huh

[@DynomiteDieselTV]

Drive pressure will tell you the answer!
