The stock FMIC?

And as for your dyno experience, you could have put the biggest IC you can fit and it will still be 'hot as hell' after a few dyno runs. I think you can figure out why, so I'll not bother with an explanation.
If you think about it, a larger volume on the charge side would take longer to fill, thus taking longer to spool the turbo... Right? The advantage of a larger intercooler is a cooler charge, so i think it's a delicate balance... not just bigger = better.

DUH....... It comes witha new Lower IC Pipe, funny thing is that is what I picked up when I upgraded to UR IC piping kit, I got the same WHP gains. It is all in the LICP. Yes the stock unit is that bad. WAY too long, expands under pressure, and is VERY tiny diameter, upgrading a LICP will net you More power, faster spool, harder more solid boost hit, a turbo that will stay in boost longer, better response, and so on, I LOVE My IC pipe kit.
I guarantee anyone who runs a stock turbo/FMIC that they will get 95% of the gains of a larger FMIC with simply a Lower IC pipe. The upper pipes may add 3WHP and of course slightly better response. ONLY Benefit I can think a larger FMIC on a stock turbo would get is if you live in a REALLY hot area, and beat you car, it'll take longer to heat soak, but then if you have humidity, well you fuct, that robs WHP.

Where talking strictly IC is concerned (no lower IC pipes involved), it seems to more or less boil down to this:
- The primary difference one would see on a dyno is due to pressure drop only. There isn't enough airflow on the dyno to gauge real-world heat soak tendencies. They will ALL heat soak after a couple of dyno runs. Therefore, if one doesn't see a difference on the dyno, it's probably safe to assume that the difference in pressure drop between the stock IC and the larger IC in question is nil at that power level. If we assume that what umiami80 is true (don't know if it is) about pressure drop not becoming a factor until after 600cfm, that wouldn't begin to present a loss until over 7000rpm around 26psi of boost or 8000rpm above 20psi of boost.
- A larger IC will take longer to heat soak than a smaller IC. How relevant this will be is affected by vehicle speed and ambient temperature. Obviously, someone in a hotter climate will benefit sooner than someone in a colder climate, and this works just the same for radiator capacity as well - just as someone in steamy Tampa, FL will realize a greater benefit from a larger radiator than someone in the land of long cold winters and reindeer (Sweden).
This being evident and being supported by what I've read from independent reports in this forum, I'll venture to say that EVOVII_SWE should be able to tune effectively with his stock IC, and heat soak is going to be less of an issue where he is than just about anywhere else on the (civilized) planet. Is going to a larger IC a good idea for him? Yes. However, I doubt it will present any significant impact to his tuning.

[QUOTE=Ted B]I suggest performing a simple search to find first-hand information from unbiased consumers who reported results from before/after testing both on the track and on the dyno.

Thats exactly what i have been doing. re-serach have proven of 12 WHP and above. Your turn to search and of course look for the BR, injen, HKS and AMS everything else is just pc of crap oh and the one that i will be selling soon

Likewise, PM "Noize" and ask him of his results with one very popular IC (one of the brands you listed above) on Dyno4mance's dyno not long ago. The difference was <5whp to be exact.
If you're that convinced the ad copy you rely upon can be taken at face value, then I task you with getting any of the aforementioned parts sellers to stand behind what they say with a money-back guarantee that I will see 12whp or better on my car, and I'll probably buy it tomorrow. Good luck!

Yes, but potential pressure drop is a function of cfm, not boost pressure. The size of your turbo is what affects this, and the 3071r isn't large enough to cause a concern except in the regions and pressures I quoted above. In other words, pressure drop is an aggravation caused by excessive volume, not pressure.
We'll just agree to disagree. Produce data from independent tests where bolting on a larger IC made a substantial improvement in a moderate hp situation, and we'll discuss. Until then, it conflicts with the independently derived data evident in the links I've posted above.

And I'd be surprised if he'd see that much. There just isn't that much of a step up going to a 3071r, maybe an extra 50-60cfm. In any case, the original point was that is it going to be critical to his tuning? I doubt it.
Ok, thanks once again for all the input guys
, from my point of view I think I can summarise this as follows:
I would most certainly benefit from a properly made good quality FMIC if I could afford it. On the other hand it would probably be quite ok tuning the car with good results using the stock IC without it causing major limitations either in flow or cooling capacity given that I “only” run a 3071 and live in a pretty cold climate.
Cheers,
