Can anyone shed some light on intercoolers for me. I'm getting my car ready for stage 2 and iv been told to eliminate heat soak by uprating my intercooler, but I'm not sure what to go for. Iv been recommended that an S3 one is a good option.
Can anyone point me in the right direction as iv seen a few different intercoolers and not sure which will be the best.

Try a Search and you should come up with lots of info and discussion about this.
Broadly, your options are:
- S3 - oem VAG approach.
- THS - Very highly regarded. Better performance reported than the S3, but S3 is still good.
- APR - Highly regarded but very expensive.
- Forge Twintercooler - Front mounted and can be used in conjunction with any of the above (except possibly APR?) and also the stock intercooler.
-
take into account fitment costs as well. The S3, THS, APR intercoolers are a bit more involved than the forge twintercooler, so labour will be more, potentially cancelling out any savings.
-
can you have twintercooler with stock??
-
thats its main design. However it will be usable with all the others with minor adaptions.
Most use it along side the stock cooler, others have paireds it with the S3 cooler for top results. Think PDT has some good deals on iirc

I have the standard intercooler and the twintercooler, it's an excellent combination on the ed30.

Hello, be looking at getting an intercooler pretty soon and as Ive been reading it seems a cheaper option to get an S3 intercooler than the Forge Twintercooler which I was looking at. My car is not a ED30 would the S3 Intercooler still work?
Also any idea of the price of the S3 intercooler and where I could buy one at a good price?
Thanks Ash
-
JKM have it for £330

The forge IC, by far, out performs the S3 cooler, and the S3 cooler is a lot harder( more time consuming ) to fit. If you are fitting yourself then the S3 cooler works out a good option, but if you pay a garage to fit it, then you might as well go for the forge as it's cheaper to fit, but more costly to buy. That made sense when i started. :laugh:
-
Yeah I get what you mean, it's looking like I'm gonna get a twintercooler now anyhow and keep my stock ic. Does anyone have this set up and able to comment on performance increase??
-
It doesn't give much of a performance increase on it's own, though the accelerator feels more crisp and free flowing, but what it allows is the timing to be advanced more which means more power, also you get less heat soak in the summer. If you are tuning a engine then this is a great add-on. :happy2:
-
Yeah I'm getting bits together ready for stage 2 and this along with hi flow cat and down pipe and hpfp are part of my plans. Do you actually have a twintercooler ?
-
Yes pal, and a s3 one too. :wink:
-
Are you running stage 2??
-
2+
-
Is it a revo? Did you have stage 1 or go straight to what you have now. Would you recommend stage 2+.
what did you upgrade??
-
I did it step by step Revo, stage 2 is great because it makes it easier to drive with the power spread out rather than one big hit. If i remember correctly i went stage one, then turbo back, then stage 2, then S3 & twintercooler, then pump + stage 2+, then finally intake. Only did the intake last because i didn't really want one but it was obvious this arae was holding the car back, glad i did in the end because it felt like i got about 30 BHP with the intake. :jumpmove:
-
So what kind of figures does your car run now.
-
have a look in the dyno thread. absolutely shed loads of graphs in there
-
Dont know to be honest, somewhere around 270, 280 i would guess. Did this time on quarter of a mile, which beats most stage one Edition 30's. :innocent: and a few stage 2's. :driver:

Cheers for the advice, I was thinking I would probably give it ago myself installing the intercooler, saw a thread off another forum and it didn't look too bad to do.
Thanks Ash

Does anyone know what the dimensions are for a forge intercooler??
I know there is a little table with the standard, S3, THS items.
Thanks

there is a table i posted ages ago on here in the performance mod section. ou just have to hav a good root around. it compared all the core dimensions
-
Not sure if you guys have noticed but there is a new TFSI intercooler in town and it is rather good from the reports I have seen:

I know a couple of people that have been lucky enough to have been running this IC for about a year now and they have been very impressed with it. S3 IC is usually ~12 - 15 C above ambient, Pro is usually 2 - 5 C above ambient!

jesus thats more expensive than the S3 and THS. you could buy the forge and get it fitted for less than the cost of that alone id bet

£100 more than the THS does not seem excessive to me, remember there is also the APR IC costs around a grand! Personally the forge does not appeal to me on the S3 because bumper trimming is required and I believe (have no proof of this) the forge combined with a stock IC will have more pressure drop.

i did write that in my post above, this one

but it doesnt give sizes for Forge Twintercooler.
Pro item looks great good quality stuff too.

a bit later on in the thread i posted the forge core sizes iirc
