Intake manifolds

[joefarmer]

Ah, I was correct. I guess the next question is why people are building these with runners 4" long....

On ppumps, packaging. For my commonrail, I'll be going with a common 450ci plenum that's butted to the head.

what is sealing the ports off to each valve?

Now you're making me question my own math. *Please hold.*

I prefer a 426 cubic inch plenum for nostalgia's sake.

 

[BigYellowIron]

Since 2008, we've had a discrete intake tract from each valve to the plenum - my original CR design: 12-IR

I was directing my previous question to you, but for some reason I am to retarded to use the quote button LOL

What is sealing each runner in the head to seperate the valves?

Yea im sure it is. I dispise (sp?) the 24v head!!!!! to many moving parts. LOL

Are you having to use sealer? Is there any machining that has to be done besides milling it flat?

 

[DIESEL_POWER]

Is the runner length going to affect things that much on a forced induction engine?

In short, NO!

 

[roachie]

In short, NO!

That was my other question. I've been thinking it doesnt.

LOL sorry Brandon...that was not my intent. That size just seems huge for a non-IR manifold (think that's what you are describing).

 

[joefarmer]

No problem. I'm still looking for my math sheet for why I did it.

 

[roachie]

Great. Now I have to do math.

 

[XLR8R]

No sealer required (not counting chewing gum:hehe... seriously, though - just a bit of machining.

 

[OT-OF-Here]

Seems like I recall,...

Seeing an intake that had TWO inlets.?? Anyone else see that? Since there hasn't been one posted (pics) then I guess it's not a hot topic. It just seems that there would be better air flow/distribution with the two port inlets.

 

[XLR8R]

... then there's some with 3 inlets - they should be best using the cast bathtub plenum; I'll pull some data off the SuperFlow this week for a % gain.

Nothing flows as well as a runner intake.

Got a call letting me know my head is done. Once it get's here i'll start on my intake. Thanks for all the info.
