Which intercooler? Top or cross flow?
Which intercooler? Top or cross flow? Im building a new kit for my car. Combo will be a 370ci around 800ish whp. Single PT76
I dont want to spend a ton, but if anyone else has any leads on a good efficient intercooler besides these ebay ones that would be great.
2 different styles here......
Which would be better? Overall 31x12x4 cross flow- 4" thick Advertised 800cfm

Or would this one be more efficient/effective? Over all - 24x13x3.5 it is only 3.5" thick but the top flow area has quite a bit more area. advertised 700cfm
How accurate it the cfm rating on these?

if the top flow has a splitter, my guess would be that one.
it would be more effienct if the outlets were opposite of each other, same with the cross flow.
i have the cross flow one, but cut off one end cap and flipped it, then welded a 4" outlet to it.

I was thinking that also... cutting the end tank off and re-welding it on the other way. Im more curious about the cores....cooling efficiency and flow.
I vote vertical flow... i am using a very similar one for my procharger setup. Check out treadstone performance, they have the exact same unit... and I'm pretty sure it's much more like 1,000CFM. The reason I say vertical flow is because I believe they are better matched for V8 forced induction where there are lower boost pressures for higher flow rates. For this case having more tubes at shorter lengths is superior to less tubes at longer lengths.
This. In a way itll force the air use more of intercooler because the way that top one(and most others) is setup, the majority of the air really only flows directly across and doesnt use the entire volume of the intercooler.
The horizontal flow configuration shown above forces the charge air to flow through very few internal intercooler passages. In addition, each internal passage is very long, causing further restriction to charge air flow - resulting in a high pressure drop. In other words, the long route with few passages.
The vertical flow configuration spreads the charge air flow evenly over a far greater number of internal passages and results in significantly less restriction. The path length of each internal passage is also shorter, further improving air flow over a horizontal design. The net effect is a short route with many passages resulting in a massive charge air reduction but with improved air flow.

Why does everyone use the horizontal/crossflow style? I built one for my Nova a few years ago and did the vertical flow style with more passages.
Would the longer passages have a greater cooling effect? I searched some... couldnt find anything.
Another thing I found... the CFM ratings on them??? 800 for the horizontal, 700 for the vertical?? How can that be? or are they just made up numbers? The SQ inches of passages for the horizontal one is 48, and the vertical one 84. So you'd think the vertical one would outflow by far... but they dont list it that way.
Trending Topics
the majority of the cooling is done in the first 4 inches of tube travel, so there really is not a great deal of additional cooling effect beyond that. horizontal/crossflow is often used for intercooler piping routing constraints... besides that I cannot think of a reason why someone would want to use a crossflow vs. vertical flow.
Another vote for Treadstone. I have thier vertical flow offset tank one in my Nova. They use American made cores similiar to Bell and Garrett. They range in price from 300-450. Not too bad IMO.
I agree, and the splitter would be easy to add. It only needs to be on the inlet side of the IC, and could be as simple (in the shown configuration) as a straight plate inserted and spot welded through a couple holes you drilled.

how hard would cutting and welding the endtank be on the one for the vert flow?
i will probably just get the treadstone though... hoping to find one in the classifids...
used parts are just as good!

[/IMG] That unit is kick ***... I really wish I could use it in my car. It supports over 1,000HP. I am using the 18.5x6 vertical flow, I am designing custom end tanks so that I can have 3" inlet and outlet instead of the 2-1/2".
I basically have the same intercooler as the first one you pictured.....31x12x4.....I flipped the tanks and put a 3.5in outlet on it....and welded my foglight mounting tabs to it also. I had a friend weld it tho.
