CCV Pressure

Beat me to the punch again. LOL

since im cleaning up the driver side and changing the fuel cooler, i want to weld a bung with a AN fitting on the valve cover. i found a -16 but its hard to get a bend that will look neat.
can i split the 2 hoses and run 2 1/2" vs 1 1"

 

[Tree Trimmer]

no.

pipe flow is kinda of backwards. to double the flow if pipe, you increase the size by half. if you double the size of pipe, it quadruples the flow

for instance, 1/2 pipe to 3/4 is 2x flow. 1/2 to 1" is 4x flow

in your case, its approximately 2 - 3/4" pipes you need to maintain the same flow. half again of 3/4 is just over 1".

two 1/2" pipes do not equal one 1" pipe.

its kind of hard to explain.

 

[BFT]

Sorry, what I meant to say is weld 2 bungs that equal the 1/2". It would essentially have to ports on the valve cover.
You saying I need to ports of 3/4"?

 

[SEABEE08FX4]

Are you talking at idle or while driving?

 

[BFT]

What you talken bout Willis?

 

[SEABEE08FX4]

What you talken bout Willis?

At what time is he trying to get a reading, (IE) at idle or while driving.

 

[BFT]

Probably better at both. I get a constant haze at idle on a big tune.
I was out and about looking to get stuff ready to take my valve cover off and getting stuff welded. Just trying to figure out what will equal the 1" or if I can do 2 at 1/2 the size, or what not.

Didn't want to start another thread on something that's beenbrought up

Draw a 1" circle, then draw 2 - 1/2" circles inside the 1" circle. Going with 2 1/2" lines you will lose flow.

 

[BFT]

The 1" line might be overkill, I don't know, but it would be good to do 1". What is suggested to vent out the excess pressure

 

[Jeff@Spartan]

I have a 1" line for mine. Dustin has two 1" lines I believe.

 

[Tree Trimmer]

if your trying to equal the flow of a 1" pipe, its two 3/4 pipes.

or its four 1/2 pipes.

i dont how to explain it better, other than to show the math.

area of a circle is as follows.

A= pie times radius squared or A= 3.14*(R*R)

the area of a 1" pipe is .785, of a 3/4 is .442, and a 1/2 is .196. all of these answers are smaller than 1" because its a circle, not a square. area of a 1" square is obviously 1".

as you can see, it takes four 1/2" pipes to equal that one 1". this is why i said it takes just shy of two 3/4" pipes to equal that one 1" pipe.

 

[Erikclaw]

Mine from Rudy's is two 3/8" lines if I remember right. Two elbows bolted into the valve cover in the area that isn't suppose to allow oil to flow freely into the elbows.

 

[BFT]

That makes sense. 2 3/4" lines it is.

Thanks

Whoa! SH!T just got technical. I'm outa here...

 

[bigrpowr]

same as trying to add up nitrous jets. a .73 and a .93 doesnt equal 1.66 ....

 

[Erikclaw]

.73
+.93

=1.66 I got learnins

Two 1/2 inch openings will have a surface area of .3927 = the total surface area of a .7071 diameter hole.

Two 3/4 inch openings will have a surface area of 0.883575 = the total surface area of a 1.0607 diameter hole.

 

[Jeff@Spartan]

So basically two 3/4" lines and one 1" line are going to work virtually the same? If that's the case, why run two lines? I would go 1" if you're going to do two lines. That makes it more worthwhile, correct?

 

[Blowby]

Maybe available space when routing the lines or the appearance of smaller lines could be more desirable. :shrug:
