thiking of DIY single pass
??
The "disruptions" itself in the manifold endplate will not cause a pressure build up in the total cooling system... (OK, there will be a bit higher pressure in the hose before the manifold than after it, but this is the same for the HE in-/outlets.) But such disruptions can maybe trap air, not good, and cause uneven flow through parallel cores due to different resistance. Also not good.
And I can see that GM designed some kind of bleeder on a closed cooling loop, as something has to relieve excess pressure when we put heat into that system.
Edit: Like EBristol said....

sigh.
here is the quick rundown.
stock and dual pass = disruption in the endplate due to design and my ********.
without a bleeder of some sort, option B, the hose on the stock filler neck, the system would start to build up pressure and explode from it if put under enough load.
gm realized this. put the little hose off of the T to alleviate this A BIT like a swollen tit.
gm also used the bleeder in option b which constantly bleeds out the pressure from this disruption.
a properly designed single pass does not have this problem. doesn't need a bleeder at all.
think of stock and dual pass without a bleeder as being in an airtight bathroom and flushing a clogged toilet.
somethings got to give, it's going to be the container.
horray.

Hmm. So a GM engineer told you that a single pass system is worthless?
This said engineer should find another job then because I've seen plenty of logs and runs that disprove that.
No wonder the stage kits aren't that great!
Like I said I gave the facts and get flamed with "oh that can't be's" and "you're crazy's", so believe what you want, it really doesn't matter to me. This is why people don't try to help other people anymore.
What. Jealous that someone a lot more knowledgeable than you took the time to explain to me how it really functions? Ok. That's fine, Leave it to yourself though.

and you called me out first with a statement implying i know nothing...and now you clamining you have logs and are bitching about getting flamed, if you have so much info why don't you use it and prove your statements...i would still like to see some proof on this outlandish statement of the IC system "exploding"
you have not provided any proof for your statements yet say you have it...you are the only one with information no one has ever heard...
The hardest part about a single pass for us has been the end plate. Modifying it to accept a single hose that feeds all 4 tubes.
the easy part was putting the tank on the other end and positioning the exit to fit in the car. If someone wanted to use all those T's and such to feed 3 inlets (on a dual pass endplate), we could sell you the LIM modified with single pass outlet. We probably have them on the shelf.

i am not sharing the information about the single pass because vendors on here would scoop it up and claim it as their own. besides, he asked me not to say anything about it.
Who said a 1-pass is worthless?
And can you please explain this new science of those facts you and some others seems to know about?
Heat in a completely closed system tend to blow things up, that's how nature works. Things expand. Running no relieve valve in the charge cooling system is not very smart...
Edit: I'm slow here...

i never said it was worthless, i said it isn't as beneficial, unless doing endurance/road racing...it is a very expensive mod for little gain unless you are big into road racing/autocross or w/e

When it's on my car and I get the ok to blab I'll be more than happy to post up the proof but I try to keep my promises to people so sorry for the time being.
It's very much benificial. As stated above I'll show why when time comes.
As for the IC system exploding, I never said that it has happened so how am I to provide proof? I was saying if under enough load with no bleeder on the stock and dual pass systems the intercooling system would give way. Single pass does not have this affliction.
I wanted to see the explosion!
It's just a bloody heat exchanger cooler with some cooling water running through. Nothing magic, you only have to take care that all cores work efficiently.

Sigh. Yeah I guess I should've used a better term. The room and toilet reference was just what was used to show me the correlation. The IM would not "blow up", but something WOULD give way under the right conditions like I said.

A very efficient 1-pass chargecooler will get a lot of heat out of the air into the coolant, more than the stock 4 (2)-pass, and the coolant will also not heat up as much. (massflow x dT)
But then you have to get rid of all this heat in the HE and there's not much of a temperature difference there to shed all this heat... So without a good BIG HE you will just feed warm water back into the manifold and in time the system will reach an equilibrium.
Oww yeah, you guys like the 1/4 mile over there.
That will work when cooled down. On longer road racing coarse things will even out more without balance...

I hope Vulcan builds that manifold fast because you're going to be without a car when this fails.

lol yeah it's not a weekend project.
bc as you can see most people on here refuse to learn how the system actually works and the fine details of it.
you can't just dive into a single pass like you can dual.
hope ya got a tig welder in the garage....

first off, the idea that you have anything of value and are keeping it a secret is a joke. Why even bother to say you have something only to say you can't share it? Oh that's right, you want the fame and glory of having 'all the secrets' while really not knowing much. Secret tune, secret meth mix, secret single pass...
ZZP will have a comprehensive review with graphs showing IC efficiency with standard, dual, single soon. We'll do a write up of HE effectiveness and have lots of FREE info that IS NOT a secret. Stay tuned...
