Im curious: why hasnt anyone considered the possibility of a double pass fmic? its an odvious solution to our pipe routing problems. just have the in and out of the intercooler on the same side. that would solve the problem dont you think? its still the same length, maybe less, of piping too. anyone think of this yet and put it into production?

yeah put people here like the looks of the others,besides,they flow,and cool better end to end.
but if your interested I recamend Hahn race craft theres is(in my opinion) the best.
you can get it from them or www.modernperformance.com (http://www.modernperformance.com)

That looks like a really cool design, has anybody contacted them? Is there a reason why all the turbo -> IC pipes have to pass back over the IC on our cars? I'm guessing a piece of the body is in the way?

I can't find it on their site...help??

It is a good idea however the air would have to pass twice as quickly through the FMIC and would be a bigger restricter as well. Double Negatives Dude...

well if you think about it the air has to go across the front of the radiator to get to the one side so why not just have the air go in one side, do a 180 either with a u pipe or some kind of custom endtank, and go back through thus make about 2 feet of useless piping useful by putting it in the intercooler. it would simplify the whole thing and simple is good.

What problems? Just get the iON kit and make the holes for the piping.:)

It might be the same length, but that nasty U bend at the end of the IC can't be better than the direct path of iON's routing.

Also, with the piping running through the stock IC location you can not upgrade to a wider radiator.

iON's FMIC kit does not have any piping that passes over the the IC. It is a straight shot from the turbo to the passenger side of the IC, and then from the drivers side of the IC up to the TB.

I have argued with many over the effectiveness of this, but I think that a lot of people around here don't think like I do. I grew up in the town that made the first atomic bomb, I learned in their schools and then later worked in their labs. I tend to think less like a mechanic and more like a scientist when it comes to stuff like this.:) I feel that iON performance has the same philosiphy. Function over form.

Maximum Boost - By Corkey Bell.

Pg. 59

"...The Top and bottom cores have the same frontal area, heat transfer area and efficiency, but the bottom core has a much greater internal flow area due to the larger number of tubes (inside) and therefore a lower pressure loss"<O:p</O:p

This lower pressure loss will flow more air with less stress on the turbine...less sturess means less heat and less reason for a more efficient Intercooler in the first place. The air in the intake tube is flowing well regardless of how long it is. The idea it to make the inside of the intercooler the smoothest and less harmful to the airflow. By making one really long small FMIC (Basically what a double pass is) you have forced the air to speed up as it gets smaller and increases the back pressure before the FMIC. The other design however, the air goes from a small tube of 2" (The same size as the turbo outlet so it matters not) into a standard FMIC. Because the number of tubes inside are double that of the double pass, the air slows down in the FMIC and has more time to give up it's heat. Then as the air leaves the FMIC, it speeds up as the plumbing becomes smaller and enters the throttle body.<O:p</O:p

<O:p</O:p

Cool? Trust me, the reason a double pass is rarely used is because it is an inferior design when compared to a single pass of the same size.<O:p</O:p

sorry to sway off topic but anyone see the srt-4 section?? Sick shit....so much aftermarket parts its insane. http://www.modernperformance.com/dcx/srt4_index.shtml
