top to bottom ro side to side FMIC?

[03MSPRO]

I am looking into getting a custom FMIC made for my car. All FMIC I have seen for the MSP flow side to side. The guy at the fabraication shop said they have a FMIC core that flows top to bottom and flows better than the side to side intercoolers. What do you guys think?

[speedhawaii]

no clue.

i think i need to pee

theres no way a top to bottom is gonna fit without significant modification to the bumper support and frame. I thought about a top to bottom but the cutting doesn't justify the benefits.

also top to bottom and side to side flow the same. There isn't an actual difference with the core, the performance benefit you get from our cars with a top to bottom is better throttle response due to less piping.

What do you guys think?i don't think it matters... because the air in the ic is already compressed, so it should be under pressure to toward the exiting source..

also if u think about it our intake manifold is up top anyways so if the IC flows top to bottom, i'll have to come back up again before goign into the intake manifold, thus it loses most of it gain..

see the ic how it flows side to side but top entering to top exiting, i belive that is the best way to cool air... Because as soon as the air enter the ic, gravity is going to pull it down to the bottom of the IC and it will get moved to the left side on the bottom and the when it tries to exist, it has to be squeezed back up inorder for it to exit. The air is kept in the IC for as long as possible making it as cool as possible...

Top to bottom (or bottom to top) will cool more effeciently according to Corky Bell, at the expense of a tricker design and install (more cutting would be required in our cars)

I think I am going with top to bottom design. This guys will use my car as a test car and make a kit to sell online.

since when does gravity affect air? if that was the case we wouldnt be able to breath at any elevation besides sea level right? anyway as stated grab "maximum boost" and read it :)

[AutoBox]

well if thats the case then the hot air enterin the ic would be at the top of the ic.....but i really dont see how gravity is gonna affect the efficently of pressurized air rushin through a ic system

[Notorious]

autobox is right, it doens't really matter because the turbo is pushing air at such a fast rate anyways. Sit in front of a fan and put a pipe in front of it, does the top of the pipe blow hotter air than the bottom???

[noclue119]

well if thats the case then the hot air enterin the ic would be at the top of the ic.....but i really dont see how gravity is gonna affect the efficently of pressurized air rushin through a ic systemwhat i'm tryign to say was that if air entered at the top leftside and exit at lower right hand corner it make a much better airflow design. but that = less time in the intercooler... while top entering and top exiting = slower exit speed, but more time in the ic

[Notorious]

also i would seriously rethink the top to bottom, take the bumper off to get an idea of how much cutting in neccessary. You literally wont have a frame in the front. You have to figure in a decent size core is going to be at least 6 inches tall. Most top to bottom mounts are at least 10x10x3. Then you are going to have to figure in end tanks, which your gonna have to further cut into the frame. To make this work your middle section is pretty much going to be non existance, which i don't have to tell you will make a difference in an accident.

[Notorious]

The flow is pretty much the same. You'll have less piping so better throttle response but your not going to really notice a difference. If your intercooler is a bar and plate cooling effeciency is much better (square tubes vs. round) so you don't need to spend that much time in the ic. Also slower exit speed is also going to mean greater pressure drop.

however i saw a guy's flow model that he did to simulate the IC and that were the results he came up with... I'm guessin he forgot about the bar/plate/tube factor

it doesn't look THAT big, but looks may be deceiving. RRE says 6" tall, now whether that includes end tanks or not i don't know. with outlets on the same side though you could use the stock ic location and cut out a bunch of piping

[Notorious]

the 6 inches doesn't include end tanks, plus we have a huge bumper support section along with a section of the frame there. The dsm doesn't appear that have the problem that we have.

[jred321]

oh they have the problem with the bumper there, i think they took it off for that picture though. it says "Minor non-structural trimming of the bumper reinforcement necessary." knowing how narrow a 1g front end is, i just thought there was a possibility of it fitting on our cars, especially since it didn't say anywhere if the 6" included the end tanks or not. oh well, i'm poor and can't afford anything anyways, just wanted to throw some pictures into the thread :)
