Dry Sump for the Duramax.

[COMP461]

I started this thread to show the Dmax with a dry sump, Ill point anyone to get good Autoverti pumps for 100 cents on the dollar

I have always had Dry sumps on my diesel engines because they give better control of oil , It keeps the blow by from blowing oil out of every seam because I have bad ring seal
My current set up pulls about 45inches of vacuum at idle

I built this pan , so anyone can do this

here it is in the car

here is then one for the Cummins I had done 10 years ago

here is that motor on the dyno 10 years ago . my first complete diesel build

here is the Duramax adapter to put out in the motor , this one has 2 outlets fore an internal pump a dry sump only has one

here is the parts and diagram of a dry sump system

the pumps

what's inside

Here is the oil pan design Curtis Halvorson built years ago ,

I have always had Dry sumps on my diesel engines for two reasons , It keeps the blow by from blowing oil out of every seam

Umm, so the benefit of a dry sump is not allowing blow bye to push oil out of the engine from your words. Please explain to us how having an internal or external oil pump changes blow by pressurizing the engine.

my Dry sump system pulls 3 to 5 inches of vacuum on the crank case at Idle and around 10 to 12 inches at full power.

Because he builds pro stock motors

Because he is the best engine builder in the business!!! Nobody else knows how. Greg as soon as I figure out how (yes I'm computer stupid but I will admit it when I need help) I'm going to link your rant about cheating to the yellow bullet tread so all the people over ther can see what you have to say about them.

 

[Stingpuller]

I could only hope!

I can only wish for that day! Be sure to wear them knee high socks so I can pull them up over your head with your skid mark stained speedo's. Lmao

 

[Stingpuller]

Yep I'm the problem

Not the fact that you post pictures from ten years ago about nothing other than to blow your own horn. Or, lie about how fast your car is because it makes you fill all warm and fuzzy inside. Or take credit for what others have done. Or talk about people and things you know nothing about.

 

[Stingpuller]

How fast your car is!

Show a time slip. It's real easy.

I like those little pumps. Where did you say a fella can get them?

Essentially the gases that are in the crank are a good combo for explosion.. Correct? Hints why the big pro tractors tend to sperate themselves at the crank case at high rpm levels and all the heat built. Or I believe. So could a fella push an inert gas through the crankcase at a level higher than the oil level into a catch can, such as nitrogen? At a very low pressure rate just to neutralize the pressure and ride the engine of all gases. it would have to be introduced I to the motor at a similar rate to the engines rpms. Just thinking out loud. Or would that be a terrible idea?

Did you just hear that somewhere, oh Great Greg?
Is this another example of "learning by osmosis" just regurgitating info youre around and being just a driver...or what?

Pretty sure I read somewhere that the stock pump in the stock GM wet sump design pulls roughly 5" at idle too Greg, and matches your "@ full power" vacuum claim of 10-12" as well...there is a minimum and ideal requirement/ratio that needs to be adhered to...GM didn't mess that up and the stock pump can and does produce more volume than required, by like 125%??? Which is why we can tap and run bypass systems and centrifuges, no problem...I'm pretty sure the Melling, Dmax performance replacement pump, can out perform your pumps vacuum #'s set up with just a spring swap...lol

Im pretty sure the main benifits for a dry sump system are being able to mount the engine lower, to attain a lower center of gravity, less windage and pumping losses and technically unlimited volume, perfect evap control, as well as precision flow and heat control...but what do I know...nuthin

And that's mainly why I am here Greg, to learn. I used to get excited when you'd post this chit, thinking some valuable knowledge would be passed along...but I always click out of the thread to find myself disappointed and concerned...I truly hope you can find d someone to post for you, like you find people to build your bucket...then at least there might be something actually mechanically sound and intelligible associated with that hideous avatar and blow hard braggart signature

Ding, ding, ding!!! We have a winner.

And I keep seeing the word "design" thrown around, but have yet to see a resemblance of any sort of "design" at all...bending/welding up some tin and a few things isn't a design, its a high school metal shop week project...

Let's see the inside of the pan, accompanied by an intelligible breakdown of the how and why the baffles work BEACAUSE OF THE DESIGN! Like each baffled area is xx volume because, it needs to move x volume per port per secocond at this load/perssure, and, the ports are this size because, the total volume is xyz because...etc

But I'd almost guarantee the one on the Dmax posted above is just open, and not baffled and isolating pickup points under critical lube/moving parts of the crank

For the love of Chrysler, this gets old

 

[COMP461]

This pan is fully baffled and when I get home from the track tonight I will show a few pictures.
Maybe then I'll also tell you about the seals that I put in to retain vacuum for the front and rear main seal and maybe the part numbers of those inexpensive double lipe vitron seals

Why don't you enlighten us with some of your dry sump oul pans youhave built over the years for the Duramax are for diesels or for anything for that matter.

But........he has a RACE PROGRAM (whatever the hell that really means) And a FAN CLUB (he's the only member)

He just wants people to tell him he's wonderful.

Did you design and build that one on your engine?

 

[COMP461]

No I did not! But I took credit for it.
Who do you think does all this.

while you're posting useless oil pan pics throw up some slips from the track with today's date. Thanks.

 

[hondarider552]

Does that oil pan on that Cummins really say ZZ fabrication?
