Any feesible reason to upgrade to a FMIC if I am running the stock S5 Turbo?

 

yes, the stock ic heatsoaks like a bitch. You'll get more power out of a cooler charge. I run an fmic on an s4 motor with an s5 turbo. Big difference vs. stock.

 

I agree, you will notice a difference with a fmic. However, if you are sticking with the stock turbo you have to ask yourself what your plans are for the car. If you want a street car I would say go with a fmic. If you want a track car where oil and coolant temps are a main concern, keep the tmic. The stock turbo is good to 12 psi. The tmic is only effective up to 10-11 psi. So, in the end you will have to make a choice which will benifit you.

 

if you plan on keeping the stock turbo, make sure you dont oversize your IC.. 12x24" that everyone seems to like is way overkill and the lag makes it horrible for street use

I have a small 12x9" fmic core on my other TII, the lag is pretty much nonexistent, just like stock

 

Well I am keeping the stock Turbo for a while at least, but I am also very interested in keeping my AC and from what I gather going FM means no AC. If can keep my AC I'll do the front mount.

After I get the car together and running I will start planning a turbo upgrade. But for now Just going to keep it simple.

I am not a big fan of the huge IC's so a 12x9 will probably be along the lines of what I would do.. But again if I can't keep the AC I probably wont be doing.

 

I have the old school trust/greddy kit from japan. Zero difference in lag.

 

If you're going to drive fast enough to where the air is sucked out instead of in the hood scoop you might want a front mount.

For a "stock" S5 turbo I'd say no.

 

What idiot told you that would happen?

 

OK Oswald Bates, please define "feasible reason".

It's an internet myth that refuses to die. I first remember hearing about it from BDC, but I don't know if he was the source or just repeating the myth. I think it was supposed to be 50mph or so that there was some type of mythical pressure reversion, or the scoop was supposedly cut off from all airflow, or something like that. As you know, there is no way a static low pressure zone on the hood of the car is going to stop or reverse the dynamic flow of ram air through the scoop, but those without a physics background would not know any better. I personally tested the airflow in the stock TII scoop up to 70mph with no significant change in airflow. Sometimes I wonder if I should have ever posted that FC aerodynamic chart on the internet.

 

Oswald bates.. Guess I am too young for that one... lol I mean if I am keeping it stock for a while, is it feesible for me to upgrade. And can I keep my AC if I go FMIC?

as for the internet myth of going so fast the scoop stops working... I never understood that... lol it makes no sense... Besides the hood has a rubber seal that seals with the IC and forces the air where it needs to go. But even if it didn't the only way air would come out of the scoop is if you were driving in reverse... LOL anyway I thought maybe he was babbling and just said what he was trying to say incorrectly so I left it alone.

 

Oswald Bates is a comical character who engages in the vulgar misuse of sophisticated words. The skit ran on FOX's "In Living Color" TV show that aired from 1990-1994.

Yes, it is feasible for you to upgrade, and there are many cars on this forum with an FMIC and a stock S5 turbo. I am surprised that you haven't noticed them.

Yes, you can keep the AC with an FMIC. However, it depends on the construction of the FMIC, ducting, and other factors.

 

I thought you guys knew me better than that. Guess I've been hanging out in the lounge too much.

 

Ok I guess I am not too young, just forgot about In Living Color

Touché on the English/Grammer lesson. My days as an English major were very numbered, and it's been many years. But I really was one... As for my spelling I blame spell check.

I have noticed them, just seems like everyone is really quick to kill the A/C so I haven't seen many set up the way I am wanting to go. So with that being said can someone provide me with a construction, ducting, and other factors that I should look for?

 

I just had difficulty understanding your wording. Spelling isn't an issue as long as the basic message is understandable. Cee, eye kan myspel wurds an u kan stil uhnderstand teh mesaige. My Oswld Bates reference was intended to add levity, plus it is one of my favorite comedy sketches.

Corky Bell's "Maximum Boost" and "Supercharged!" books have an entire chapter dedicated to intercooler design and installation.

 

What about going with water/meth injection? I am considering going with it on my GSL-SE/S4 TII with stock top mount. It would allow you to avoid the long pipes and lag. Just a thought.

 

Y are u hijacking my thread with your meth/water question?

 

He is suggesting that you could use ADI rather than stressing over the FMIC.

 

just fyi, this weekend i took to the mountains in 100 degree weather and did a lot of hard driving.. even with a really hot engine (almost overheated several times), the TB intake temps never got above ~108F during hard runs. the temp sensor at the AFM was reading about 160F!

this is with a 20"x9" ebay fmic setup on stock s4 turbo, pushing about 10 psi. I doubt you can claim less than 10F difference from ambient on the stock IC. fmic = definite upgrade, stock turbo or not

when idling still, the TB temps will creep up to quite a bit, matching the temps at the AFM, so dont call BS on my readings

 

water/meth injection is gay crap. I hate these little additives..
might as well 200 shot nitrous the intercooler core.
