FMIC Flow ratings
 

Has anyone flowtested those e-gay intercoolers? The ones that are like $60 from "JAPSpec". They would be a good deal if I could belive they were really "CNC machined and factory TIG welded", I'm sure there's some poor Taiwanese kid with a TIG welder slaving away for a sandwich-a-day.
If not I'd like to know if people have had good results with those.

3,391 CFM :o with Zero pressure drop :S

You're funny ;)

I did a flow test on a ebay intercooler and it worked great.Now shut up and support CDM nog

The eBay ICs flow really well, better than anything that actually does a good job dropping charge temps. You see, it takes the charge coming in contact with the IC for a significant period of time for heat transfer to take place which creates - of all things! - resistance to flow. This is why tube fin > bar plate.

However, the eGay ICs are a really good deal. Just go as big as you can fit and they do work well at that point.

Don't you mean bar&plate > tube&fin

Most of the ones off ebay are crap, but there are some decent ones as well. Just do your research, and fine one that's a bar and plate style, and ensure it has many, staggered, turbulators on the inside to stir up the air. If you can look in one end tank and out the other, I wouldn't buy it personally.

No, tube fin > bar plate. Bars have too much interior volume compared to tube design with plenty of turbulators. Datalogs don't lie.

TRUE DAT!!!!

Interesting. On the DSM side of the world, the Bar and Plate cores are the most sought after due to them usually have a superior internal turublator design. Most of the tube and fin's with internal turbulators that I've run across do not have nearly the density of turbulators as the bar and plates, or their turbulators are perfectly alligned down the tubes, which really won't stir up the air much at all. Tube and fins tend to have less pressure drop because the air can fly right through them, but that's not what you want. Like you said, you want the air to stay in there, and you want it to be stirred up a little, so max heat transfer takes place. All high HP rated IC's like Garret's 1300hp cores, or PTE's 750hp cores, Perrin 1000 h[ cores, Spearco, etc... there is a reason their cores are bar and plate, and people ditch the old Greddy 24 row tube an fins for bar/plates. I have never heard of anyone try to claim a tube/fin core is better.

Turbulators in a bar/plate:

Also attached is a pic of the inside of an "internally fiinned Tube/Fin":


Which one looks to you like it has more surface area inside to cool. Which one looks like it will stir up the air more so more air molecules come in contact with the surface?

Thats a poor ass tube and fin

Horrible comparisn
