Re: running a series of intercoolers?
 

the only thing i pulled out of my ass is the temps, but anyone can see if you have a big aluminum box filled with hot air, as the cold air goes through it, the cold air is going to get hotter

Re: running a series of intercoolers?
 

So basically, as i was trying to explain, the largest, thinnest intercooler is the most efficent.

Re: running a series of intercoolers?
 

there was a 300zx in the latest modifidied mag with dual sidemounts.

Re: running a series of intercoolers?
 

he even says right in the passage you quoted that increasing thickness will increase efficiency, but as you go thicker and thicker the gains in efficiency will not be as great. Basically you need to find a happy medium.

didnt they come with dual sidemounts?...its a bit easier/more practical if the car is twin turbo

Re: running a series of intercoolers?
 

I'd have to agree with tealcherokee in regards to larger IC's height and length wise are better than IC's with thicker cores. Here's a quote from corky bell's maximum tuning, "Core Thickness Choosing the thickness of the intercooler core is a bit of a juggling act similar to the turbulators. The juggling act is brought about by the fact that the second half of any core does only one-fourth the work. Adding thickness to the core will indeed improve efficiency, but the gains become less and less. Another negative effect is brought into play by increasing the thickness: the increasing difficulty of getting the ambient air to pass through the core."

lol.... i just quoted the same thing..... great book, defintly worth the $40

Re: running a series of intercoolers?
 

thats comparing 2 intercoolers of differnt thicknesses, with the same frontal area.... so a 12x12x2 vs a 12x12x4 double the suraface area, 25% more cooling. double the surface area and leave the thickness the same.. 100% more cooling

Re: running a series of intercoolers?
 

well in my experience its usually easier to go thicker than to go much bigger in frontal area. Im not arguing with you, just saying that there is a practical limit to the dimensions of an ic, and in most cases i dont see the need to go to extremes in either frontal area or thickness

Sig material :y

Re: running a series of intercoolers?
 

Things that you have to put into consideration:

Internal volume, IE how restrictive is it at a given cross section (vs overall). That restricts flow, obviously, but also a higher velocity inside leads to better heat exchange.

External airflow, which is both the mass moving though it, and how easily it can move through it. To give you a better idea, assume both fmic's are 24" long: a 12"x3" core will have just as much internal volume as a 6"x6" core, but air will want a move MUCH slower through the thick 6x6, because of pressure drop. It essentially slows the air down too much. WIth fmic's its not a big issue, since that large of an air mass being pushed through it at even 30mph wont' slow down much for anything. It will try to go around it though...

As mentioned, use two smaller ones if they can support the flow and you have no reason to go with a big fmic. I saw two stealth cores on ebay, but the owner expected a shitload. I was also thinking of that if I ever wanted to use a car w/o AC and maxamize cooling to the radiator.
