i do agree that just adding row upon row of cooling surface area will not work without proper end tank design and flow design, fluid and air share some of the same properties but not all, a great example of this is extrude honing services,.

 

extrude hone is great, if you can afford it

gasses and liquids are both part of fluid dynamics.. i wasnt implying liquid flow. sorry for the confusion.

 

Everytime I see a giant intercooler or 3" IC pipes I cringe.

The BEST intercooler for a car is a function of boost (and therefore boosted air temps), and that's it. The most efficient pipe diameter is only a function of displacement and RPM limit. Yet people strap intercooler systems on their cars which add 10 cubic feet of volume for the poor little turbo to try to compress. I'll never understand it.

Why do you want to lose efficiency? Use the proper sized IC for your application please. 300whp does NOT require a huge IC and you will NOT benefit from it. Infact you will lose performance.</TD></TR></TABLE>

Watch what happens to your dick if I see it near my car. . .

lol how many clamp did u use? i see like 12 just to connect the ic (nice setup though)

 

That right there is alot of money in t-clamps

 

Im looking at getting a turbo setup atm and the intercooler is 24x12x3.

Is this too big for the front of an EG?? How much bumper cutting will I need to do? Dont know if I should keep looking round for a 6 inch deep IC to make fitting easier?

Thanks (I did try a search)

if you mean that air will go in and air will go out, then i wont argue. if you mean to say that adding row upon row without altering the tanks is efficient, i will disagree. im not qualified to explain the intricate details to anyone as i struggle to understand them, but fluid flow is very complex and not really related to common sense as much as we would like. i certainly wish it was a 'bigger is better' situation.

here is a summary of a fluid dynamics course that i often refer to. i think its pretty good if you care to look.

on the real, how much HP can you gain for getting a properly designed FMIC with the right end tanks for the application?

 

 

thats a good question, and if i answered it with a number, id be purely making **** up. straight from the butt dyno, literally out my ***.

horsepower has more to do with how much fuel enters a chamber and is burned by a certain crankshaft degree. the limit of horsepower in turbo applications is usually the detonation threshold, where air temps come in.

intercoolers are about how much air comes in at what temp, how much air goes out at what temp, and how long did it take. if the intercooler lowers air temp, sure, detonation can be staved off and higher peak horsepower numbers are possible. if you win races on a dyno, then go for an IC thats way too big. if you wanna beat the guy in the other lane, size appropriately and have a car that recovers faster. (flame away.. ofcoarse you can catch up to him with more and more boost. and he can walk away bragging you needed more pressure to run the same time.)


i agree with beepy's statement above and see no reason to pay for, make room for, and then pressurize an intercooler with volume in excess of the engines airflow requirement.

to me, a huge intercooler just screams "get a prybar and steal me.. im worth $500 on ebay all week."

im all for air/air IC's,, but they look like these on the left with long tanks that taper down to a pointed wedge. baffled into thirds on entry AND exit.

want it done right, pay big bucks or fab your own tanks.

 

Anyone have pics of sav leones car when it first came out, aka Impo performance. I believe that car has all these beat. And it had a single cam motor. It was in a sport compact car mag years ago. I believe.

 

That is a good install

 

thats nothin, check this out:


yea I know the return sucks, but ohh well. .

 

where can you find the cast style end tanks like on the endless garage cars and alot of the supras?

 

You can get those from Apex.

you can fit it on an eg if you cut the bumper support and bumper...not a bad idea

that is what I am going to do with the intercooler that I have...its about that size

then I will get a bigger one for the integra

good point several people have made about choosing an intercooler and pipes that fit your power level, turbo size, and rpm range, so the intercooler you are talking about 24x12x3 is good for around 600whp or maybe more, so if you are only pushing 300, it is pretty big unless you have a decent sized turbo

as far as my set-up goes, I am going for 800+whp, I have a huge turbo (with a 3" outlet) and I will have a 90mm or 100mm throttle body, and will be running a 10k redline, so anything less than 3" i'c piping would be restrictive and that size intercooler is too small for optimum results

basically it depends on your set up and goals...and you won't need a 6" thick i/c unless you are going for crazy numbers...I probably do need it though.

 

each additional inch of core thickness is less efficient than the previous one because heatsoak is spreading through the inner layers. if you think you need a 5" air/air, its time to go liquid/air.

an engine of a given displacement/rpm/compression ratio etc will require a certain mass of airflow to make a specific horsepower. if you require 250cfm, there is no need for an intercooler than flows 600cfm. that was the whole point. do some math, and size accordingly.

 

Corky says the last half of the thicknes is less efficient because the amient air is alreayd heated by the time it reaches there thus less cooling.

that is true, but you can only go so wide and tall before you have problems (fitment), so although the last half is less efficient than the front part, it still works and still helps keep the intercooler from getting heat soaked...better than just having a thinner one

nice e-cutout


I dont know, but some of those enormous IC's with endtank ports on the very bottom, seems pretty inefficient for cooling the air at the top.

i agree...mine will have custom end tanks that will eliminate this problem

The two brothers with civics with huge IC's in this thread appeared to have good end tanks. They were curved metal rather than just made from plates and started expanding from the pipe a good foot back. The only negative that I saw was that it originated down low and expanded up rather than from the center and expanding downwards. But this is probably due to a fitment issues with the rest of the bumper components.

 

If you really wanted to improve the efficiency of a larger intercooler, why wouldn't you use end tanks with two 2" inlets and outlets instead of one 3" inlet and outlet? The flow would be the same and it would ensure equal pressures throughout the core. Maybe its just too hard to make the pipes all fit.
