I think this maybe a old subject but i have searched and not found what i'm looking for so i thought i'd ask.

Right, I'm thinking of upgrading my IC and i'm torn between a Apexi GT/Koyo NFlo and a V mount, i really like the idea of the V-mount and if i went with say a RW one they use Triple/Twin pass Rads and the IC core is 4" thick so still a decent size.

I have done a bit of reading up and most people say having a 90degree anywhere in the Inlet Run isn't ideal (should be as smooth as possible, the air speed has to slow to turn a sharp corner) so the V-mount with its 90degree end tanks would cause an area of bad flow?? But in the real world would that be seen as a power drop if you are moving allot of air through it? if you back to back tested the two IC set ups would there be one that makes more power (assuming both air temps are the same at the inlet maybe using wi??) then would a deeper end tank help with the 90degree turn (for example the 4" thick RW as opposed to the 2.5" Radtec V-mount we have here in the UK)

This is an Example of what i mean... First one note (I think) is a Radtec V-mount and has a 2.5” core


This seems to be a more ideal end tank but would have to be Custom made and there for proberly out of my Budget...


But most i have talked to say scrap the V-mount idea and get one of these.. Old school and you kinda know what your getting, but would it not hinder air flow to the Rad?


Ok my next Question, If it turns out the 90degree end tank is fine and there is no Noticeable flow issues i was thinking on using Pre Turbo WI with this set up, Would the Air entering the 90degree V-mount slam into the back of the End tank causing the Nicely Atomised Water Vapour to turn back into liquid? or would the sheer volume of air flowing through turn it back into Vapour just as quick?

Last question, this may sound a little dumb but just something that’s crossed my mind, If you are using a V-mount for racing and you have it all nicely ducted etc so all the air coming through the front of the car is aimed at the rad/IC when you start to get really fast air flow (120mph upwards) doesn't the Air speed damage the Fins on the cores as it isn't hitting the core straight on as they were designed for?

I kinda hope this makes sense...

That is why I like the HKS V-mount so much. It is a high quality tube/fin intercooler core with well designed end tanks.

They do look nice, i also like the TB elbow you get with the kit (much smoother than the greddy one) I think its PWR that Copied the HKS set up but i am not sure if the end tanks are as nice. I would seriously look into getting the HKS kit if they wern't so rare.

Yea..I love the intake elbow as well. They aren't that hard to get (thought you must import them)...but you have to pay $$$$$$$ for them now. When I got mine in 2007, the exchange rate was still about 120 JPY/USD and shipping rates weren't so astronomical. Think I paid 1900 USD shipped back then.

that is an Apexi intercooler and they did something a little interesting, you can kind of see it in that picture, but they built a core that is the normal width and height, but its a little thicker, and the tube density is lower.

the lower tube density lets more air pass thru the core, so more air goes to the radiator.

Grizzly

Yep if i went FMIC thats the IC i'd be getting the Apexi GT (4.5")

They really did think about the core design when they made it


And the Core Vains are much larger than most of the other makes


Then they also have well designed end tanks so they are going to flow really well both Internally and externally. mmmm i'm selling myself the FMIC

like i say, i don't know a lot about FD intercoolers, but my friend has a hill climb FD that is about 400rwhp* and he runs the Apexi IC, and his intake and coolant temps are stable. his cooling system is the 99 stock radiator (denser core) and that IC and that's it.

*400hp in a straight line isn't bad, but on a twisty mountain road the car is SCARY fast
