just get rid of that tube ****. i swear, you could post that on any car forum, and no one would believe your a vendor planning on selling it to the market. Fins are a must for good heat exchange.

The temps u posted were non boost temps, ur iat's were ~120*f during no boost. The manifold hasn't even seen real heat yet. U can't post how the ic system works from #'s of zero boost. Would need to see the temps at WOT and full boost. Zoomer is right. That manifold won't work. Too many things are wrong.

Also what pulley r u running? Hope it's a stock or close to stock one bc I would hate to c a ld9 blow from the insanely high iat's of a 2.8 or 2.7 pulley. I will believe zzp over oem bc they have set the bar for m62 power pretty high. 365whp on the m62, never before seen. They know how high iat's really get

We are gonna add some fins, thats the whole purpose behind a proto kit. You test and test until you achieve the results you want. The way it is now, it works, boosted IAT's or not it lowers the temps. With fins on the plates, that will add surface area to the over all tubes and will be even more efficient. It seems to me that doing this will work even better then the current set-up.

I'm gonna have to LOL.

although, anyone got any idea at what putting runners like that in our manifold would do?

bolus

are they running liquid nitrogen through those tubes? That's probably work

Thats cool, I will have some IAT temps under PSI on Thursday for everyone.

awaiting results.

What pulley is on ur blower?

slowswap

Freaking awful. This better not be the substitute for the design we discussed.

lol. that one isnt even vulcan...which im pretty sure ur already aware of?

slowswap

My bad. Still a horrible.

dohc v6

I am not understand your comments I guess. If I show the results whats so bad about it? Its a proto kit. It seems to me that people on here follow a crowd instead of actually posting a comment that makes sense. If you have something besides, man its ugly or LOL, then please post. The manifold does cool the air as needed, and we are just making it better to prove so.

Hell no! I posted this to help oem see that their design is terrible. Not to promote :p designed we discussed is by far a lot better than this.

What pulley size is on the blower? 2.8"?

well, for starters...you shouldnt have ANY change in intake temps using that on an NA application. you're using ambient temperature water to cool the ambient temperature'd intake charge... you cant cool 80* air with 80* water.
On top of that, there's more surface area in half of a laminova than there is in your setup there.
Then there's the fact that its a 4 pass system, and as thus, will provide the least efficient cooling possible from a liquid to air system. I dont see how you think that there is a temperature drop here in your NA test....

The whole point of any intercooler system is to remove the heat that was ADDED by a compressor by taking the hotter air charge and running ambient temperature water or air (depending on the type of intercooler) through this hotter charge. The two temperatures will average out to a degree.

How do you think you can cool ambient air with ambient water...?

dohc v6

^^, I am not sure what you are talking about. I think, you think, that the air going in is going to be the same temp all the way to the head. That is not the case at all. Even though the car/ charger is not making boost, the temps from the charger will raise the temps in the manifold and therefor raise the IAT temps. When driving, you are pushing air over the hot water, that is probably around 150*, and cooling it to a good 90* over the time it takes to get back to the manifold. Am I correct in saying that you think that because the air going in is the same temp as outside that it will have almost no change.

Out of boost, the cars IAT2's will only be about 20 degrees above ambient air temp. The main flaw in your design is the water to air intercooler, even with fins is inatqiduete(sp? lol). There's a lot of time and research into making a water to air intercooler core that sufficently cools the air, allows for good air flow, and doesn't over heat the water.

dohc v6

Exactly why this is a proto kit. If it needs modifying, thats easy to do now. Also I was seeing around 160 on the IAT temps, not sure but my iat temps with the NA manny on is around 90-120.

Try single pass, more cooling tubes with fins, possibly smaller to add more tubes, for more surface, area so you can get multiple rows of tubes for better cooling. Ofcourse all depending on amount of room. Might work....

I applaud them for trying and doing trial and error to get this to work.

ok..first of all...is the charger installed or not?
If you're not in boost, and never were, then the charger wouldnt be hot at all, and definitely wouldnt be heating the IAT by the (at least) 60* you claim above. If you WERE in boost, then why dont you have test results with numbers in boost? I can easily place my hand on my blower even after a WOT run when the pulley is 3" or bigger. You seem to overestimate the heat the blower will make when its not making boost...
you may have up to a 20* increase from ambient to IAT2 with non-compressed air. Where does the added heat come from? The engine bay is hot, as are many of the components in it. Knowing this, the coolant that is circulating around in your engine bay is also likely to be a few degrees over ambient temps (maybe 10* warmer).

Using these numbers, we see that you are trying to cool a 90* IAT2 charge with 80* coolant flowing through tubes that conduct almost no heat due to almost no surface area, when the ambient temperature is 70* anyway.

So how the hell are you seeing 150* when out of boost?
