i think this is a good question, but would be better suited in our power adders forum...

But to answer the question, in my opinion 2 turbos should be counted as one power adder because most people know, its usually more beneficial to run only one large turbo, I think the main reason alot of people use twins, is just for bling factor, and ease of installation etc...

But in my opinion, to call an intercooler a completely separate power adder is just retarded...

Think about it like this... Turbos run off of exhaust gasses to make power. The turbo, being that it is basically one piece, retains all of that heat from the exhaust, and it spreads to the compressor side, which drastically increases the temperature of the charge in the compressor. I would imagine intake temps. increase from 100, up to 300 degrees, just from the time it enters the compressor inducer, to the time it exits.... An intercooler is neccesary to cool this air, to efficiently AND safely make the power from that compressed air... Its basically just a supporting mod... That would be like, banning bottle heaters on nitrous fed cars.... Granted, the dry ice thing might create an unlevel playing field, because when put into perspective, thats almost the equivalent of nitrous guys using blow torches to heat their bottles, which as far as I know is illegal by all sanctioning bodies...

So maybe they should be told to just stick to ice and water, but to completely ban a liquid to air system in favor of an air-air would be ludicrous.... I personally like the idea of the dry ice, and having intake temps. below the outside ambient temperature... My hat goes off to whoever discovered that....
