I just laughed at you. Out loud.

The rate of heat transfer is directly related to delta temp between the fluid temp and air temp. The larger the delta the more heat can transfer and at a faster rate. So yes, a slower pump can cool better than one that is too fast.

The reason a faster pump will work well for Paul is because of the massive cooling capacity he has up front, which can adequately drop the coolant temp while at a high flow rate.

 

Yes, yes it actually does

 

So you laugh but then you prove my point.

 

No, no it actually doesn't

 

I did not. Reading comprehension > you.

How about instead of being an ass, you re-read and learn something.

Moving fluid faster, with no other changes, decreases delta temp which decreases the rate of heat transfer.

 

Then explain it using equations, because right now you're only stating opinions. General rule of thumb increase fluid flow to increase heat transfer rate if water or if air.

 

If this is a simple middle school project why do you keep getting an F when you talk about the subject.

You said earlier the greater the delta between the fluid and the air will transfer heat faster. That statement proves my point. If you have a pump that flows fluid slowly through the intercooler it will cause the fluid to heat up. As this fluid heats up it loses its abilty to pull heat as fast as it could when it first entered the intercooler.

Q: Why do people run a dual pass endplate vs a stock one?

A: The fresh cold fluid spends less time in the intercooler keeping the delta between the air and the fluid as high as possible pulling the most heat possible out of the charge.

If we run a high flow pump it helps to keep the fluid from heating up. This keeps the delta between the fluid and air as great as possible and therefore allows more heat transfer to take place.

 

wat

 

Hahahaha

 

sneak peak of part of the setup

 

but onto some more info
with the stock pump (which only lasted a week on this setup brand new btw) I was seeing a water temp increase of 15 degrees compared to inlet temps (before cores after cores) new pump maybe see 6 degrees, iat's decreased a decent amount along with system recovery time back to ambient fluid temps.
soon comes the fun test of below ambient fluid temps


but I would add that this pump would be way overkill on a stock h.e. non dual pass setup

 

You can't pull general rules of thumb out of thin air. That is absolutely not correct.
As far as equations, it's not that simple. Equations with what numbers? As a "general rule of thumb" with even a modest understanding of physics, flow rate has zero impact on heat transfer rate. It's all about delta temp.
A dual pass works not because of time spent in the ic, but because you have 2 cores getting the coldest coolant instead of one.
2x the core coverage of the best delta temp.
Allot your same reasoning to the front HE and maybe you'll see the huge flaw in your logic. Open your damn eyes and look at the whole system.

Exactly. Flow would likely be so great that your approach a constant temp, cutting best transfer rate.

 

simple terms.

If the pump flows too much you run the risk of pushing warm coolant through the heat exchanger before it a chance to have the heat "pulled" from it. the system, in turn, is just circulating warm coolant with minimal heat extraction. obviously some heat is pulled, but not as much as could/should be. If you take the opposite into consideration, too little flow and you don't circulate enough coolant to effectively cool the air charge. There needs to be a balance somewhere in the middle

When you are running a complex setup with multiple heat exchangers, even though the coolant is traveling at a faster pace, it spends more time in a heat exchanger.

Again, there needs to be a balance of all the different variables. Too small of a pump with too complex of a cooling system will putt too much stress on the pump and the system won't function properly. Too big of a pump with minimal cooling "mods" and you run the risk of inefficient heat extraction

Obviously this was already stated, just tried to sum it up in simple terms. There is a lot more that goes into it, but this is just in regards to the bigger pump=better argument

another, even more simple example:

you have a refrigerated tunnel, and a warm can of soda. if you have a major league pitcher (higher flow pump) throw the can through the tunnel, you are going to get your soda fast, but it will still be very warm.

if you rolled the can through the same tunnel with a gentle push, its going to take longer to get your soda, but it will be much cooler

 

lol and if you have a very complex h/e setup and a high flow pump, it might flow the same as the oem pump with stock/mild cooling system

 

Hey, look! Someone gets it.

 

Good points that I agree with and when you have a h.e. system like 06blackg85ss the fluid temps always come back to ambient before entering the intercooler. So therefore using a better pump that doesnt allow the fluid to heat up as much in the intercooler will pull more heat from the charge

 

You still dont get it

 

It has nothing to do with being tough. I'm saying you're wrong because you're wrong.

 

i forgot to say "in for the lulz"

 

Ooooooooh ok. Him and I said the same thing, but he's right and I'm wrong. Genius.



Keep trying.

 

 

No, he made some valid points. You are trying to say a stock intercooler pump will be more effective at pulling heat than a pump that flows 5x more which is false.

 

depends on the rest of the system...

 

Wow this thread has gone off topic. Let's talk about all of those heat exchangers. I think you may have too many in the system. You can only pull so much heat out of the incoming air with the laminovas.

 

This is another valid point, at what point does having more and more heat exchangers become a moot point because the laminovas have already hit their peak limit of cooling capacity.
