hey, I'm rather skeptical myself, I think the idea behind it is is to cool the center section down enough to reduce heat transfer to the intake side of the turbo(since I dont think its really gonna cool the exhaust side anyway)1400 degrees isnt gonna be cooled by a bit of A/C but just because you have never heard of it is no reason to call it stupid, it may very well work for all I know, its not like it could hurt anything to try(A/C really isnt all that cold, what? 40 degrees at best?)
