And yes, Panic...I paniced a bit myself when you asked the question on the blower rotation...I though i had checked that 2 years ago when I first started piecing this together....but luckily it still is the correct rotation...;) I was thinking about that this morning, although it gives more rotating parts and more noise for sure...you could machien a little raotation reverser using a pair of quick change gears, which could you could use to help any offset on your belts if you need it and while your at you might as well design it to be able to swap the gears easily without taking the belt off....I wonder what those suckers sound like at speed...of coure you can slow them down with you belt pulley choice.....blower whine and QC gear whine under your hood, could turn some heads...;)
