Random Idea... Would it work?

[rickyrickster25]

So i was looking on ebay the other day and a came across a pretty nice looking used FMIC and it got me wondering, instead of a CAI, what if you rigged up a turbo-less FMIC system in a NT car... Would it gain you anything reasonable?

I mean if you look at it it seems like it would be a good idea, but would the FMIC slow down the flow of air to an NT car? Or would it actually cool the air better then a CAI? Is this just a dumbass idea? lol

What do you guys think? I think it would be a fun project and its not something you see everyday which is why i would want to do it...

throttle response would go down peak power would go slightly up

I think you will lose performance on the whole.
I came up with the idea of the turboless FMIC along time ago. I was going to do it when I had my FMIC laying around before I put the turbo on, but I didnt get around to it before I went ahead and turboed it.

[rickyrickster25]

Yea i found a forum about it but all anyone did was bitch at eachothers input so i figured i would try it here, but the throttle response was brought up. Is there any way to mess with the system to make it work better? I just like to fabricate up crazy shit and i think it could be a fun idea to work with, plus a FMIC looks sexy on a 2g but i wouldn't want to have it just sitting there...

Why would he lose power on the whole? Eventually the cold air will reach the intake in a cooler form then it would with a traditional style intake. There is something to be said about pressure and velocity and all that stuff but he never specified which type of routing and which size pipes. I believe that if its done properly to his setup there is at least a couple hp's to be gained from it. WOuld it be worth it in dollars/hp no chance but what would cause the overall hp loss?

There would be no performance gain, infact it will be a negative. The job of the intercooler is to cool the hot air from the turbo as close to ambient as it can before its consumed by the car. On a NT car, since the air is in the intercooler is going to be negligibly different than the ambient air temp, the opportunity for performance is not there and thus the intercooler is nothing more than a giant blockage in the intake tract.

Its a pretty simple thermodynamic problem, a body A at temperature X cannot cool a body B to a temperature <X with out work being done on the system. Since no work is done, even at 100% efficiency (intercoolers are not, I believe its something more like 75%-80%?) the lowest possible temperature of body B is X. In other words, the lowest possible temp assuming 100% efficiency of the intercooler is the ambient temp. In the NT system, since the ambient temp is essentially equal to the intake temp, the intercooler is doing nothing.

True story. The rate at which the air changes temperature varies directly as the difference in temp between the charge air and the ambient air/IC. With only a ~20 degree difference the drop would be minimal. The lower density of the charge air wouldn't help either. The weight of the IC would negate any minor gains, which would probably too small to measure anyway. A CAI is much lighter and more cost effective. Even still, every 11 degrees drop is only good for 1% gain IIRC, which on a low power non turbo car just doesn't add up to an appreciable gain in most cases. For example, at 200 hp, a 10 degree drop is good for ~2 hp, etc.

I understand what you are saying, but wouldnt the fact that the wind was blowing on the intercooler have some effect on the temp change, or is that just one of those things that isnt the way it seems?

Are you figuring having the filter on the end of the IC then the other end going to the intake? You will have no gains with that because the air is blowing into the filter and going through the core. The air temp at the filter and the core is same temp (ideally if filter is where a CAI would be). The air since it's not moving at a fast rate, just sits and takes it time going through the core and will actually warm up (depending on air temp).

Basically, no.

[SilvrEclipse]

Everyone is correct. It will not improve performance at all.

[rickyrickster25]

Alright well thanks for your input guys.

[talon sleeper]

speaking about random ideas. does anyone know if it would be reasonable to swap a 1997 talon esi motor out with a mitsubishi evo motor. just an idea that i thought would be cool to really have people guessing if that was really an esi that blew their doors off.

[Thor06]

Yeah dude, its been done before.

[talon sleeper]

Alright i was just wondering about the transmission and how all that shit would work with swaping those engines. Like wether the transmission in it now would work or if i would need to use one from an evo too or not. Haha because i have no idea with this stuff i am just starting to get into it.

[david-b]

If you have no idea on this stuff... don't even try. Everything has to be replaced and used from the EVO
