Im sure you figure that because either someone else said it, or you just assume 50lbs of iron and steel cant hold up to "the elements". The inlet runs air down from a snorkel and dry sock so air wise its fine. Water wise...shouldnt have a problem...lots of turbo cars drive in rain all year long in Washington and none take a crap. The placement itself has about the same amount of crap flying around as a normal placement of a turbo and is as efficient as the worlds most efficient manifold-turbo kit for the Hona k-series. So why is it the "worst placement for a turbo ever?"
