What are everyone's thoughts on the Forge IC? Would you recommend any other particular one since they all hover in the same price range? I am a fan of the cooler not being sandwiched like the factory one is. I would think that it would promote a cooler charge, or is my logic flawed?

It's cheaper and easier to install.
And looks cooler. (No pun intended.)
The TWINtercooler definitely helps but testing has shown the APR IC to be the best. I just wanted a true front mount.
So incoming air runs through both coolers at the same time? It sounds like an uneven amount of airflow will pass through each respective cooler. I'm sorry if this is a dumb question. I've never seen an intercooler setup like this before. What kind of pressure drop are we looking at by adding a second core?
I feel the same way...I have the forge twintercoooler on my R...I also noticed more power through the mid range (more torque)...you can see my dyno numbers on my thread on the HPA Haldex/GIAC 2+ Review...I say it works very well especially on the track!!!
eace:Quite honestly, your biggest benefit comes from getting more flow for the charge air. The intercooler acts as a heat sync and can cool off at higher speeds or when you're not at WOT. Most cars don't really spend a whole lot of time at WOT so they don't really risk heat soaking the intercooler. I mean think how fast you'd be going if you pull for 30 seconds at WOT.
I would guess you would be around 150 mph? When I did the dyno pulls they were about 20 seconds long and redlined just about 120mph in 4th. I like WOT though it is fun!!! :vampire:
Sort of, incoming air particles flow through one or the other intercooler, but not both. So any incoming air will only pass through a single intercooler on it's way to the cylinder. Basically, they are set up in parallel, not in series. The bad news for cooling is that the outside air flowing over the intercoolers that cools the air in the intercoolers sees them in series. Most of the air getting to the stock intercooler has already passed over the Forge Twintercooler.
The pressure drop for the Twintercooler should be lower. The extra volume means the air is moving slower, which should decrease the pressure drop. Also because the air is moving slower, it has more time to cool off as it is passing through. That might mostly offset the effect of the outside air seeing the Twintercooler and then seeing the stock intercooler.
I have it and I like it, but don't really have anything to compare it to. It did make a noticeable difference when I installed it, but I don't have any dyno numbers to back that up. Not really sure this would show up very well on a dyno, because you don't have the necessary airflow to really make it work.

Bingo. I dyno'd my car against an equivalently equipped R minus the fact that he had a forge setup.. On the dyno, we pulled the same numbers (or close enough), and on the road the cars were about the same too. So.. it's a tough quantification.
That being said, when i was at WF18, in freaking hundo degree heat, idling the car in line at the strip for 15 minutes, it definitely would have helped.
That's really good to see that several people have it and like it. I'm sure on the freeway is where this setup really makes its money. Thanks for the feedback! I appreciate it! :thumbup:
That wouldn't happen to be testing by APR, would it? Do you have any information on the test you can share?
Sort of... I think it was scottisha's car that they demonstrated it on.
That is the same info I have heard of, and I believe you are right about it being on Scottisha's car. As I mentioned earlier, the benefits of the Twintercooler probably won't show on a dyno. I don't remember exactly what info they gave him to convince him to make the switch. I am sure they really wanted a full APR kit on the first stage 3 R they built.
Oh I don't doubt that, nor that they may have interpreted the numbers in their favor. It should be noted that both the Eurojet and APR intercoolers actually do show improvements on the dyno over stock on GTI's. I know we have a somewhat better intercooler, but I wonder just how much better it could be and if it's enough to hide the performance improvement of the Twintercooler. Ultimately, it's up to each individual modding to do the research, make the choice, and then live with the results.
