What I need is to get my IAT down significantly with the engine at good operating temp. Either a big aux tank for the IC with COLD water or some meth seem like viable options.....

mike if you look at some of brianbraves threads you will see that he tried the bigger tank and what the result was longer times between heat soak but the coolant eventually heats up to temp no matter how much is used. it simply cant be cooled down quick enough to justify a 5 gal tank and the weight associated with it.
now the meth thats a different story!!
