Hey! This is my first post on this forum, and a pretty dumb one at that. A few guys were talkin about 550 fan cooled sleds and the 500ss liquid cooled sleds when a guy brings up that he was drag raced by a 550X fan, while he was on his 500ss. He says there is nothing wrong with his sled and that the 550X must have something no other 550 fan cooled sleds have hahaha..oh excuse me. But anyways, I have argued black and blue to them....And yet they still say that the 550X is stock and the 500ss has absolutly nothing wrong with it. Can someone please agree with me that the 500ss would eat the 550fan..PLEASE!!
