I'm not... I'm talking about my own long awaited design... the one that began last fall.

 

oh, lol. I remember that. Well, then there should be some competition for prices then. 3 options is good.

 

To clarify though...I'm not going to compete with vendors... I'll only to one-offs as per request.

Rebal and OTT have put on too much time for me to come in and swoop business.
I did mine purely for my own build.

 

well, just hit me up with some test numbers once you get them. Like IAT's, flow numbers, dyno numbers, and track times. Whatever you end up getting.

 

4 possibly...

i just got ahold of a second lower intake manifold, im not going to go as crazy as Omega5, more along the lines of what the average modder can do to the stock manifold.

 

still waiting on answers from the vendor........

 

You can throw my name on the list, I gave you guys my manifold to test while I was deployed ( well the company you worked with anyway ) so why not just give you a 100 bucks and say I helped with the cobalt community some.

Its for the people right?

 

damn just when i thought i had decided on the hahn turbo swap, this is getting interesting.

 

main questions : why copper with high convection via FI? and not aluminum?
What kind of flow design are we looking at? counter flow? parallel?

more i look at it, the more id rather chill the HE a bit better with a better coolant/method to maximize the efficiency of the intake mani. Brainstorming here....

 

Shaun and my self

 

Very interesting stuff, but i'd have to see real world gains before I'd commit.

 

Copper has higher thermal conductivity than aluminum. This should be self explanatory, as we have copper coils in our air conditioning units in our homes.

Thermal Conductivity (in W/m*K)

Copper 401
Aluminum 237


To answer your second question it will be cross flow or as us nerds would say "perpendicular" flow. Very similar to a radiator. Are you a degreed engineer by chance?

 

YOUR A MORRON AND A SELF ABSORBED JACK ASS WITH NO CONCEPT OF FLOW OR COLLING DYNAMICS

STOP POSTING

 

cmon guys lets stay focus in the topic, you cant get ideas from words like idiot or jackass
im not telling hes right or wrong, since i dont know
but i know that flaming people will not get me the answer

 

yes css.net is on an uprise lately with all this great info lets keep it civil.

 

Do not go there buddy, no flawed physics here. You think you know everything pal. GOOGLE cant solve all your problems. Im not going to get into this one indetail with you but just dont bring me into your arguements like that and insult me

this prooves how much you need to learn, coper is much better for this aplication then aluminum and LEWIS showed you why a few posts above.

You claim your very smart but to ask that question prooves that I guess you couldnt find the answer on google this time


this makes me respect you even more, Im sorry we got pulled in again by rrutter.


OK now Im done jacking the thread. This will be interesting to keep an eye on and it could be a very successful product if done right. Back on topic and let RREBEL get back to thier job

 

Yes - Copper is ideal in this situation. This does not act like a radiator. High end Rads use a copper core with aluminum fins. The copper conducts the heat to the lauminum fins which dissipate it to the air passing through the fins. Works great.

In the case of a liquid-to-air charge cooler, there is no heat dissipation in the IC - just heat transfer. The hot air hits the copper cores and fins and heat is conducted to the cool liquid running throught the cores and to the Charge coolant radiator (which should be copper core with Aluminum fins) - this is where the heat dissipation takes place.

 

Google solves specifics that you ask and is a good resource. Im going to avoid the bashing for now, we can do this in another thread.

I think i will step out, if this will be a copper core. I dont like the misinformation being flung around here. Obviously im an idiot (once again) so keep on with the copper and disregard the fundamentals of aluminum. I mean its obvious my physics are rusty, my engineering skills are on par to a pet fish, and i have no idea what i am talking about and never have.

good luck

 

rrutter - see my post above yours with regards to copper core within the actual intercooler

 

yes i agree however there are set backs to the reliability.

 

Ahh - yes, yes. I see what you are saying.

However, there are a number of copper alloys that can be used in place of pure copper (which is very ductile) without sacrificing much of its thermal conductivity. You just have to use the right alloy if you want to make cores and fins out of a copper varient.

 

I agree with you there if you are talking about the reactions with DEX-COOL. But that is something in my car would have already been changed. People do need to understand that dex-cool is bad for the copper and that has been proven in the past. Its is bad for high lead content solder too. If you do go to this or the REBEL heat exchanger you do need to change over the cooling system which also has to be done with high care to fully clean out the DEX-COOL.

But agian copper is going to give you the best cooling capabilities but other things need to be done with this system to make the copper ok

 

hit the nail on the head.

I dont feel like taking my intake manifold off every 6 months just to be slightly cooler than aluminum by a few degrees. I dont race funny cars.

Also ANOTHER good point made was the cooling system. I think some gains can be gained modifying the intake manifold how it stands, but modifying the dynamics of how the cooling system works will be MUCH greater.

Also copper vs aluminum is really a toss up. If you want to rebuild your engine every track run you build your 1500 hp ecotec. However if you are a daily driver (like me) keep the aluminum. You will see ALOT better gains through a redesign of the system than just changing the material.

my .02 cents

 

agree to disagree?

 

hmm this seems like a good idea but we will see
