Correct, bar and plate. I will try to locate the link for a US company I dealt with several years back that used an extruded tube design and then vacuum brazed the cores. You could order them in any size that you wanted and the price was ~$350 for a core the size of what would fit in an EVO. I had them make a custom unit to my specs for my TT 240Z. Intake temps ran ~12deg above ambient.

BTW, a guy contacted me the other day and sent me a link to Nisei Engineering and they had a good writeup on intercoolers. They have a nice setup for the EVO.

nisei's core is pretty awesome.

id prefer tube and fin for road racing.... with the ic and rad sandwhiched right together...

lighter... and more air through the rad.

cb

 

i see ur point...

bigger most flowing for road racing?
combo of lightest and flow for drag racing
and sexiest looking for the street? lol


cheers?

 

for roadracing you're lookin' at two factors. weight and heat. if you race in greenland... even though it's melting i'm doubting that heat transfer is gonna be a problem. so a lighter core is due...

for roadracing in southern california high deserts, you'll need every pound of radiating aluminum you can fit.

florida... i can only imagine it's worse with the humidity, did they even put intercooler sprayers on the evos there???

 

Interesting info on the extruded tube cooler. Full race uses this design and this is what they had to say about it.

"Thank you for your interest in Full Race products. The intercooler core was designed to optimize surface area to pressure drop. Extruded tubes allow you to have only the amount of material necessary, not more. Bar and plate style intercoolers that flow the same amount, simply have a bigger pressure drop, which hurts power. Attached is an image of the core. I hope this information helps you and if I can be of any more assistance please do not hesitate to call. 866-FULL-RACE."


Full-Race now offers a stock-fit front-mount intercooler with a 24"w x 12" h x 3" dia high flow tube and fin core. The intercooler core is rated at 1320 cfm flow capacity and has a 282cu/in surface area with less then 1 psi air pressure drop increasing power output significantly. This core features extruded tubes radiused on the ambient air side to allow for smoother cooling air flow for additional efficiency.

 

^^^^ that is an awesome looking intercooler, buy 900 dollars wow

 

That extruded core looks familiar. BTW, nothing like a nitrous backfire
The company I dealt with would also let you choose the fin density as part of your desired performance. I also know the company that makes all the cores for Spearco. Hint, it is not Spearco!

 

any macro pics of outside?

 

Got some more pics to add to collection. Here is an HKS intercooler for s13 car. looks like it could be used on an evo. Core size is 24.75 x 12 x 3 . This core is obviously made by same manufacture that makes the factory evo core. The factory evo core is 19.5 x 11.5 x 2.75. Fin density of HKS in a bit higher on the inside with 30 bumps, the factory only has 17 bumps in a row.

here is the factory core for comparison.


Here is a greddy intercooler for the evo pulled from for sale thread. I am thinking this extruded core would have very low pressure drop but from the lack of internal fins I am not sure if it would cool better than stock. That doesn't make sense. You would think a major player like greddy would test a product before they put their name on it. I am thinking this type of core would work really well when teamed with alky injection. The alky acts like a second intercooler so a super good/big cooler isn't really necessary. Low pressure drop becomes more important.

 

Well here are a few pics of intercoolers for comparison

first one in the link is spearco wave technology.

This is old school spearco


XSPOWER below



Precision aka Garrett Core



Yonaka Motorsports Core



Full race(PWR Core I Think, tube and fin)



APEXI



Some no name brand tube and fin


Buschur per previous post uses a garrett core now
Bushur old spearco core(looks like old school spearco not wave tech)



Nisei Core, similar to Garrett may just be garrett


Looks like the xspower is similar to a few big name intercoolers in here, I think for road race something with a garrett core or nisei would be good, as far as 1/4mile I am sure most will be fine. The guys with the BIG HP, may have to let it cool down some hahaa

 

you don't happen to have closer ones of the hks right?

 

Wow, those are some nice looking end tanks..

I started a thread asking about a place to have some custom end tanks made for me a little while back, but didn't get much of a response.

Does anyone know where I could have some made just like the ones pictured above?

Obviously these are cast, so that may be a little more expensive and limit my options, but if anyone has any ideas, lemme know..

 

Here is the evo version that has endtanks that would match to factory piping.. I think the angle of inlet/oulet is a little better on s13.

 

What do you think about 2 intercoolrs on evo side by side , is it good or bad idea ? I think something like this <:><:> !

How good is FullRace for street ? Is XS beter ?

 

Why would you do that?
