    Olly, we've all been there before mate (well, maybe not with the supercharger air-filter thingy though ). You're not the first person to be sucked in by sales shpiel, and you defo won't be the last.

    The great thing with this club though, is that if you ask & take in the advice given, you'll save hundreds, if not thousands, of pounds when it comes to tuning your motor.

    I wasnt suggesting that he actually run the standard cooler at this boost level, but i admit the advise was wrong .

    I have driven a GTT with both a front mount intercooler and double cap intercooler piped in running a T25 at just under 25psi. Full boost was around 3800 rpm and the car performed very well.

    Btw, don't take it to heart if you think someone is having a pop at you. Defo not the case whatsoever; just merely a bit of rtoc/boards banter (borderline sarcasm ), which I'm sure you'll realise & appreciate once you've posted on here after a while, been to some of the events, met some of us in person, etc etc.

    It's all good

    Re: alloy intercooler

    Random question and probably an obv answer. Does it matter where you put your intercooler? Like on a cossie one people tend to have it on the lower grill thing on the bumper or on the grill. Would it matter if you had it at like an angle going down the side of the rad? Am i right in thinking it dont matter where it is aslong as a good amount of air gets to it and its not a massive circuit?

    As long as it fits, it is getting a good supply of cool air, and the pipework isn't too restrictive, then yeh - anywhere is good. But obviously 'anywhere' won't necessarily get you all of the above

    Exactly, although I didn't get sucked in by the fuel cat cr8p. As for the spark splitter though...

    Re: alloy intercooler

    I was going to buy the pipes and fit a cossie 2wd cooler instead of using my strapped O/E jobbie. I'm running 14-15psi. Is there any benifit or point in doing this? After reading this I think not.

    If you're mounting it at the front, I believe plenty of other members have done this and indeed endorse the mod Sy. I don't think there have been any back to back comparison tests conducted on it though.

    Working out the volume difference between standard and Cossie 2wd coolers might provide you with some help.

    There used to be a brilliant intercooler article on the old site. Has the data been saved and xferred here?

    I did read the article on the coolers and remember the standard and cossie2wd being the same volume. I'm just thinking air flow. Surley its better to have air going in one end and out the other rather than in and out the same end...

    Re: alloy intercooler

    As per the intercooler article on the old rtoc website...


    The standard 5GTT core and it's standard replacements are 200mm x 200m x various mm thicknesses with a U bend half way. Straightened out this standard shape equates to:

    400mm wide x 100mm high x 80mm thick = 5GTT standard cooler core, phase one or two.
    400mm wide x 100mm high x 80mm thick = Pace standard replacement.
    400mm wide x 100mm high x 110mm thick = K-tec or Forge standard replacement.(ô)
    400mm wide x 100mm high x 130mm thick = GTTuning 'Double Capacity' standard replacement.(ô)
    400mm wide x 100mm high x 96mm = 2wd Cossie cooler core dimensions.
    460mm wide x 115mm high x 120mm = 4x4 Cossie cooler core dimensions.
    500mm x 165mm x 60mm think = Forge FMINT104.(ô)
    495mm x 180mm x 60mm think = Forge kit for 5GTT.(ô) (I'm told this size by an owner)
    above are all core sizes.

    (ô) I think I am correct in stating that these all use the Alutech extruded duct with the fins glued on.

    The standard replacements mainly have the same number of ducts, 14. I have seen one with a turbo Technics sticker on it with 12 ducts for charge air. It was also about 100mm thick.

    The cross sectional area of the ducts varies from make to make and this has a direct bearing on flow resistance, as well as cooling ability.

    NOTE: NONE of them are double capacity
    The standard coolers are both 80mm thick and twin cored.
    The Pace 'double capacity' cooler is 80mm thick and twin cored.
    The K-tec / forge 'double capacity' cooler is 110mm thick and twin cored (≈35% extra).
    The GT Tuning 'double capacity' cooler is 130mm thick and twin cored (≈63% extra).

    As far as ducting cross sectional area goes though the ≈ % extra I mentioned has some variables. On some the weld partly obscures all the duct inlets and exits so reducing area, but some have longer duct area front to back so that increases area. Reports are that the K-tec / forge work a bit better than the Pace. The main advantage of the GTTuning one might be it's reduction in charge air flow resistance due to the extra duct cross sectional area.


    Cross sectional area of coolers end, for what that's worth:
    Standard 80cm2
    2WD Cossie 100cm2
    Forge kit 108cm2

    Cross sectional area of coolers front:
    Standard 400cm2
    2WD Cossie 400cm2
    Forge kit 891cm2

    Volume
    Standard 3200cm3
    2WD Cossie 4000cm3
    Forge kit 5346cm3


    The early Escort cooler is a bit odd looking as it has a small air/water cooler (charge cooler) at one end of the air/air intercooler.

    Well done Mart. So the Cossie is bigger. So is it a worth while Mod?

    That data needs to be rejigged and put into the articles section....

    That's three recent suggestions now and I'm not seeing any feedback

    Sy. You're unlikely to get an absolute answer mate. Given mine and Mart's posts and if you already have the cooler then get on and fit it. Whether you see a perceptible improvement or not may depend on your boost level and whether your GTT is fuelled right. My advice is - go for it and find out.
