Ok, another thing I want to look at. Maybe I should make this a new thread, but whatever.
I want to build a new IC for my VMIC setup. I feel the one I have now may not be the best design, but I don't really know enough to be sure about that haha. I have a Rotary Extreme Monster VMIC kit. The core is 18X11X4.5, but what concerns me the most is the end tank design. There is no smooth flow to it, it's just pretty choppy, if that makes sense. The first pic with the black IC is my current setup. I'd like to do something similar to the second pic, and/or maybe the third/fourth pic. I'd also like to put some guides inside to make sure the air flows to all parts of the core instead of just through the middle.
I know I don't want air to move too fast through the IC though or it makes use of an IC kinda pointless. Sean from A-Spec suggested using 3" inlet and 2.75" outlet to offset that. I'm also looking into IC core size, and I'm not really sure what to get. I have an idea of what CFM to look for, somewhere around 740 at 10psi or 1300 at 15psi, etc, but this is somewhat based on my current turbo. Is there a way to use lbs/min (that the turbo is capable of) to get an idea of what CFM to look for? I'm thinking about going to a little bit shorter length, like 14", and keeping the 4.5" thickness and maybe going with 10" to get close to 740CFM (at 10psi, according to Bell Intercoolers which is where I've been looking). Or should I stick with 11" and go for closer to 800CFM? I was also looking at maybe stepping down to a 3.5" thickness, but Sean was saying the length of the IC will affect pressure drop more than thickness, which is one reason I'm thinking about stepping down to 14". I'm not too educated on all this flow business haha.
