    Is anybody here running the Forge Twintercooler on their S3?

    I'd like to get some feedback on installation as it looks like there is some trimming involved in the fog light areas. Is it possible to install the twintercooler without the trimming?

    Also would like some feedback on performance gains and any IAT data if possible :icon_thumright:

    Andy (BigAndy S3 Stealth Beast) had one, and had mixed opinions about it.

    From what I've read / heard the mutiple cores for engine radiator / intercooler / air con rad limit the effectiveness of airflow to the core of the IC, rather than the OEM IC not being good at what it does. I am looking to install WMI in the summer as whilst I hate temporary solutions, having a boost controlled supply will mean it gets used up far less quickly and should significantly increase the air density and low actual temps (as well as cleaning the carbonated valve heads!).

    I'm not saying don't go for it, the Forge FMIC that replaced my Leon's side mount intercoolers was pretty good, but the OEM SMIC's were badly flawed (airflow was restricted by fogs).

    I'd be very interested to see some before / after logs.

    Thanks Warren, I agree with what you've said and think the main benefit of the twintercooler is the place where it is located and the fact that it works in parallel with your existing intercooler.

    I have seen some good results of its performance when mounted to the S3 intercooler but this has always been in hotter climates. So I am wondering how much benefit it would really bring here in the UK.

    I've also considered WMI but it is not really practical for me due to the number of miles I cover - around 400 per week. I think I would be going through quite a lot of meth!!!

    I can see that there are benefits to this,but personally I would not lash out this sort of money on an add-on device,when I can buy a single,bigger intercooler for a similar price.

    Fair point. I think installation with the forge would be a lot easier and as an add on it will be easy to remove when the time comes to sell. If you were to replace the OEM cooler I think it would be more of a fit and forget jobby.

    I thought the 2.0TFSI /S3 had an FMIC? Does it have twin side mounts then?

    It does indeed. The S3 one is slightly uprated compared to the 200bhp TFSI one though

    This is what the S3 OEM intercooler looks like:

    The Leon with 1.8T BAM engine (225bhp - same in S3 8L and old version TT I guess) had SMIC's.

    As per KRL's pic, all new 2006> cars have FMIC.

    Would it not be all 8p 2.0Ts that have them not just 2006>? Pretty sure mine has an FMIC just with plastic end tanks unlike the S3s alloy one.
    THe OEM S3 one looks huge can't how anything below 400 BHP would need additional SMICs, especially in the UK?
    I would imagine they'd create a fair bit of extra lag.
    I read somwhere everywhere significant bend in IC piping is equivalaent to adding a few metres of extra pipework in the reduction in flow it causes.

    If you have VCDS please can you get some pre and post logs of IATs for comparison?

    that THS FMIC looks far better then having an FMIC AND two SMICs! The forge twin cooler set up just looks completely ineffecient.

    Akash i think your getting things mixed up. The S3 has a FMIC which you fit the Forge twintercooler infront of or you remove the standard FMIC and fit the THS/APR one. There are no SMIC`s involved anywhere.

    I would really like to see some cold hard facts as to how the Twintake performs on the S3 in the UK because everything I read about how it performs on the GTI abroad is good!

    For example:

    s3 has intercooler placed behind the radiators. i think it's ok at lower speeds, but i think forge FMIC will help at higher speeds. but first will have to try it to confirm that.

    Ok, please could you reply once you have it?

    Am particularly interested in how it fits and how much trimming you need to do.

    I've really though about this forge twintercooler and was wondering would it be worth while replacing the standard s3 intercooler with the pro-alloy one and then also using the forge twintercooler on top or would this not work (or is this overkill) for stage 2+ (and possibly BT).

    I think that would probably be overkill. The S3 cooler is already good so adding the Twintercooler should make the whole setup extremely good and easily provide enough cooling for big turbo setups as well as the K04.

    finally got it!!!!
    spent the whole day mounting it. but it was worth it. had the problem as the Forge front mount intercooler for s3 8p won't fit facelift without modification. my tuner phoned forge and they said that they didn't know that untill few weeks ago... seems that audi did lots of changes behind the bumper on facelifts. anyways...after whole day, cutting hoses and trimming front bar, making custom inox pipes, trimming of front bumper we made a perfect fit :rockwoot:
    the problem was that the left side IC pipes won't fit so we ended with doing custom pipe.
    here are the pics:

    and now impressions (i only did 30 miles since fitting so will post some more impressions after some milage):
    first: i think that car and intake sounds louder than it did before.
    second: it pulls slightly better, but from 3rd-4th gear it pulls like a beast!! i think there is a nice power gain throught the whole range, but over 60mph there is a huge difference!!
    i'm glad that i did this mod...cheers :beerchug:

    great information and apologies for any problems in this not fitting straight onto your car , we were lead to believe by ETKA that this would fit .
    Now if there are any UK guys with a facelift S3 2009 we would be happy to see you at Forge to look at the changes we need to make to a nice simple install , the happy helper would leave with the Forge twintercooler on his car at an unbeleivable price , we would need the car for 1 week
    please let me know if you are interested

    well...at the end of the day it worked very well..the right side hose fits perfectly the problem is the left one as you can see on the pics. but we've made a solution.

    @ xnox202: the last one, or do you mean without foglight mesh?
