Richmond Hill,
Is it possible to have 2 intercoolers in your car, one that is mounted in the front, and another mounted behind the passenger side wheel and have them connected? This is on a 92 talon turbo.
 
Just a plain bad Idea, thats why people don't do it.

The stock IC would be a big restriction and any temperature drops would be negated by the loss of flow. A properly sized FMIC should be able to cool the air appropriatly and flow good aswell.
 
:laugh: I love the introduction of the Hyundai.

I would only consider the frontmount+stock sidemount idea if my FMIC isnt sufficient for the turbo (heatsoaking) that it necessitates a 2nd intercooler. Then again, I would just get a bigger frontmount and use a shorter piping. You want less pressure drop and shorter piping will give you that.
 
That video never gets old :laugh: :laugh: :laugh:

on-topic: I'm not sure the extra trouble will justify the power gained from having a stock side-mount and a frontmount ic , if there is any power to be gained from that .

well there isn't much planning to it, just run a pipe from the turbo to a front-mount then the pipe from the front mount to the stock side-mount then the side mount to the throttle body....
If you're putting on a FMIC, it's pointless to run through a sidemount besides.
would this be a good idea? or is there a good reason y people don't do this?
thanks for your input guys :dsm:
Flow restriction and intake volume. Both are bad. You're having to pump through all the pipe you put between the turbo outlet and the throttle plate.

What's been done is what works.
 
A FMIC and SMIC, bad idea.

However, many people have run two factory side mounts with slightly madified endtanks, dejon even made a piping kit for it. One sidemount on each side and a Y pipe from the turbo to both. Looked bad ass, but not extremely efficient.

The biggest drawback to the front mount and side mount idea is the huge difference in flow ratings. You would always be limited by the cfm rating of the factory SMIC. Like said before, it would be more efficient to just run the FMIC :thumb:

All good points mentioned. One more thing though...intercoolers rely on temperature differentials in order to transfer heat. If you have a properly sized FMIC to begin with, the outlet temperatures are going to be close to ambient. Expecting the much less efficient small SMIC to further cool this charge air is a lost cause. The flow restrictions you suffer from FAR outweight any cooling that might be accomplished.

Having a air-water IC after though is different, since you can have an cool medium like ice water to effect heat transfer.
 
The pressure drop using 2 IC's would outweigh the benefits. If you want to cool the intake charge more, go with water injection and/or an IC-cooler.

That is an interesting idea. Do you think a single stock SMIC is sufficient cooling for a T-25? I wonder if you would see any difference w/ two side mounts.
 
well guys thanks alot for the input, but when i put this plan together in my head i thought of the flow restriction and i didn't figure it'd matter 2 much (guess it does) but i didn't think of the side mount not cooling as much and actually warming up the fmic's air...that is a damn good point Jehu. but like Jehu and turbodsm90 said if you use a ice cooled side mount that would be really nice....but this is my daily driver, so i'm gonna go ahead and just go w/ a fmic only....
 
Just one intercooler is a huge restriction to the flow. Imagine having one large FMIC and then a small, inefficient SMIC. You would be severely constricting the flow. If you existing intercooler is not flowing/cooling well enough, the answer is not another inefficient intercooler. The answer is a larger, more efficient FMIC. The only set-up that would necessitate 2 smaller intercoolers, would be like on a twin-turbo set-up.

Unfortunately, I've only seen those dual SMIC setups for 1g's. If anyone had a 2g kit, I'd be all over that (for road courses, doesn't matter how much IC I have it's gonna be heatsoaked, but I *do* need to avoid blocking my radiator with anything! Would be nice to have MORE IC though for a little extra insurance). However, I don't know that there's enough room in a 2g for it to work anyways.
 
well if anyone's interested in making their own dual SMIC kit, I have a couple of very nice 1g intercoolers laying around. Dual 1g intercoolers sounds like it could be a very good plan, capable of holding up to a 16g (which is what most people go for).
 
Nope. That is not how it is done. You would put an intercooler on each side. Slightly modify the intercoolers to use a little bigger piping to increase flow, and route like this:

Turbo to driver's side intercooler
Driver's side intercooler to pass side
Pass side intercooler to TB
Use 2 1/4" piping and it might flow and cool good enough.....

Maybe I should make a kit and test it :p
 
I know some people upgrade to supra smic's, so why not try with those? Too big? They would allow more cooling then the stock smic.

I wouldn't say, "Nope, thats not how it is done", more like thats not how YOU do it. I think dejon's setup is the better, equally routing charge air through both. That would avoid heatsoaking just the first IC and ditribute the cooling. Just opinions.

Bottles are for babies, and water injection is just a band-aid for an inefficient intercooler :thumb:

Supra IC's are just a little too big for my taste. Even bending car parts (which I do NOT like to do), it just isn't a good fit. It ends up a little too far back, pushing the wheelliner back just a little (my wide track tires actually touch it then). It also hangs down lower than stock, and I've already crushed the inlet on a stocker after a "yump" on a gravel rally...

I've got that old slightly bent SMIC around, I should get a new inlet on it and start playing with trying to fit it where an A/T cooler would normally be. I still don't think I'd reasonably be able to get piping to it though.

Why don't you link some pics to this setup, I remember seeing something about it, but never pics. I was just thinking for ease of installation, most people are not capable of fabbing up the piping for a setup like that. Obviously he is trying to save money, and that way would not be the way to do it. I for one run a Big Front mount and would never run dual side mounts as it would be a waste for my setup.

And by water inj. I assume you don't mean meth. or alch. injection also in that comment because the reason for running such as system is to prevent knock from running pump gas. I would not call it a band-aid for inefficient intercoolers.

No doubt this is spoken more tongue in cheek, but I disagree :). Different means of achieving the same ends maybe, but water/Alcohol is more akin to running race gas then a bigger/better intercooler.

My brother ran this same duel sidemount design last season. Both intercoolers had 2 1/2' in's and outlets. With one intercooler in the passenger side of the front bumper and one in the stock location.
It worked well for him with a 16g running 12.30's at 113mph. I liked it most because it was so stealth under the hood you didn't see the y pipes the way he fabicated it.
