I wouldn't go so far as to say causing the radiator to overheat but definitely, radiator temps go up about 2-3 degrees. But yes, it can happen, no doubt.

Precision does NOT use Garrett cores, and haven't for quite a few years... At minimum before 2006

 

It's called improper setup... Full radiator, two fans, A/C on full blast and my coolant temperature is the same as a factory vehicle. Given, I am running a 3" core, but the same would happen with a 4" core. A lot of it has to do with turbo placement… As was stated by another member, it's not the easy setups that are the best. So many details get overlooked it's pathetic. This is truly what keeps most vehicles from being "great". That blanket statement could be a 200whp car or over 1,000whp car (given the 1k HP car had to have some sort of thought to make it there, haha).

The vast majority will prefer the most basic combination to get the desired horsepower levels. The problem is 90% of those setups will lack nice power curves/usable powerband for their intended purpose. I have said it again and again, numbers don't mean crap, a purpose built vehicle is where it's at. The driveline is only two-thirds of the equation. There is such a thing as an all around performer as well.

Huh? Where am I?

 

Maybe a stupid question, but I have always wondered this.

Why are there no Cooper Intercoolers? I mean Cooper is has a higher heat transfer then AL.

 

Rubber does NOT have better thermal transfer properties. Unless you mean copper and not "Cooper"... then the answer is simple: Money.

 

Expensive and heavy.... More expensive than heavy tho.

 

And every crackhead would steal your intercooler...well atleast around here.

 

here too. THey'd skip the car and head straight for the intercooler

 

What about having the exterior AL and just the interior fins Copper?

 

Copper is mainly used as a component for heat exchangers that deal with water-to-air, more than anything air-to-air. They also keep microbes from contaminating systems better than aluminum, but the application wouldn't work as well with an air-to-air exchange. Copper is also not as durable as aluminum and for something like a street car, would be damaged very easily to a point of failure much more quickly than a well-designed aluminum core would be.

Now if your talking thermal conductivity, yes.. but the purpose of an intercooler is to dissipate heat, not transfer it.

This is a liquid-to-air heat exchanger at Ft. Jackson as a cooling unit

Nice... let's talk about BOVs on Intercoolers. Anyone want to start off (besides myself) as to the history and some technicality as to why this particular nuance started?

 

The answer is obvious, the history may not be. I am going to hold out until I see what other people have to say.

 

Ep, epp, epp... Stop being a negative nelly.. Let some explanation come into play. Its not always as obvious to others as it is yourself.

You keep trying to kill my thread... Don't worry, be happy

 

I was curious about this..

 

Yes, about 75,000 miles of it . It has encountered parking stops, driveways, rabbits, road gators, and small children. I think its time for a replacement.

Going to go with a Garrett 24x8x3.5 core. Will need it with 2" and 2.5" outputs. I think I can fit it without too much effort. Garrett rates it at 600hp and I can keep my bumper intact.

 

Ill bump for some BOV talk because I have a Turbosmart with my build, Ill have to check which one but am wondering what kind of luck people have had out of them and how they perform. its mounted near the TB, I figured you wanted boost to relieve as close as possible when the butterfly in the TB closes...

 

I would assume it's to vent from the hot side of the intercooler instead of the cold side, preventing some hot air from entering and transferring heat to the intercooler.

It seems like it would keep the intercooler temperature down slightly, but I'm no expert.

 

I logged on to this thread today to ask this question, and noticed you already ask it, this was one of my main dislike about the FR single backdoor FMIC, I hated the BOV on the side of the intercooler, I am in Germany and its mostly wet here and I was worried that since at some lower speeds the Bov opens. I really do not think there are any functional value to it, just the showoff part of it, which in my opinion is pointless.

 

I never noticed any advantage with putting the BOV on the endtank through an intercooler like that. There was supposedly an advantage of better recovery, but I really didn't notice it on the setups I help put together nor to others.

That's why I don't see any obvious benefits, from my experience with the phenomenon. anyone want to man-up and give the theory behind it?

 

I believe the thought process was to prevent compressor surge by placing it close to the turbo. The DSM people believe it displaces higher temps, but let's be real.... The air is going to come from both sides of the IC when it opens.

 

Ahh, but at what flow rate? Pressure differential anyone?

 

Come on keep it coming. I need to finish builing mine and the IC on this new set up does not have the BOV on it like my first one. Should I put it in line on the charge pipe or install it on the IC

To be honest I don't know much about turbo setup's and all. And I have bin following this thread for a while. A lot of good info in here.

So BOV, Is there a difference where you mount it?

What about Air to water? Not much info on that yet...

 

Well, if N3V3R starts to say something nice, I'll continue.................












....... Who am I kiddin'? I can't hold my breath that long.. Ok, so onto Air-to-water vs. Air-to-Air (A2A) intercoolers.

Generally speaking for street setups, there's no advantage running an A2W over an A2A setup, other than additional room in the engine bay. there has been no addition in power or efficiency with it. However, on Drag racing setups, you'll notice a bit cooler temps in-between stages sitting in line waiting for your turn.

I'll get together a formal write up here soon k?

 

If you run A2W you will have a lot less pipe, wouldn't that be a advantage? Faster response? Or will that be not noticeable amount of a difference? With A2W you will have less pressure drop too right?

(yes Im a noob and like to be spoon fed lol)
