    But anyway, does reducing heat soak sound like what I need? And if so, how would you recommend I do it most effectively without heavy modding of the car, voiding any service I will ever want done on it at the dealership? I'm sure there's a link to it around here somewhere....
    Avoiding heat soak isn't a huge deal. You will have no more issue with it than any one else with a WRX or STI. If you're worried that much about it, look into Phenolic spacers.

    Its not so much a function of the intercooler but of the intake charge before the turbo. If the air outside is already denser the turbo doesn't have to work as hard to compress it, as well doesn't generate as much heat during compression. So not only would the air charge alone make more power the intercooler and turbo are more efficient at lower temperatures thus the entire assembly making more power.

    fmic introduce a much greater surface area to fill vs the tmic. This greater surface area means the turbo has to take more time to fill it and thus creates lag. Sure a fmic sitting in traffic will not heat soak as fast as a tmic trapped over the engine, however while moving both will only get you down to ambient temp and that's under perfect conditions. No intercooler is perfectly efficient so you'll only get close to ambient.

    the cooler the ambient temp is, the cooler the cooler stays. Get it? .. its all proportionate. The internal volume difference is the only thing that robbs the fmic of being king. Even still a larger aftermarket turbo and the proper tuning will eventually need the ability of a fmic.

    Factory snail.. the tmic is just fine.

    lol That's the second post from you here that I have no idea what you're talking about... I'm glad Shawn got the reference, but I didn't. And why would this thread be locked? Am I asking stupid questions that qualify me for a new fire-retardant suit?

    I have a bad habbit of blasting ill informed forum members for bad info.. especially if the advice/info they're giving out is easily dismissed by a quick search and a few lines of reading. No intel is better than bad intel.

    hahaha.. nah man, its not. The more you hang around the more apparent the dynamics are

    bottom line though and to stay on topic.. outside temps will and do heavily affect turbo car performance. Just a matter of physics and chemistry.

    And this thoroughly answers my question. Thanx everybody!

    Yeah, you'll pick up on things quickly...Shawn's a bit of a loose cannon and is always good for a bag of popcorn here and there. Lot of inside jokes that you can be on the inside of too (like Zax's pants...he lets everyone inside them).

    lmao

    I've picked up on quite a few things so far (coughDREWScough), but some still manage to fly over my head. Thanx for clearing things up!

    fmic or tmic you can only cool down to ambient temp anyway. Sure you dont feel it with a fmic but believe me you ARE affected by the higher ambient temperatures.

    giving bad advice is frowned upon around here and there are dozens of studies around to show that fmic on oem turbo's aren't worth the lag or amount of money you'll have to throw at it.
    Well Excuse me... But IAT do effect how the ECU deals with timing, I believe 126*F or so the ECU starts to retard timing so you loose power... No? As for saying that I got rid of heat-soak, well YES, I DID, even with a TMIC so I do not have to deal with it any more... I guess the bad advice could be linked to the fact that I didn't explain how I did it...

    Nothing bad about what I said at all, Factual and possible, maybe what you should have done was asked how I did it...

    I'm asking!! Clear the air, please!!

    EDIT: Read your profile. A water sprayer? Really? How and where?
