Hi everyone, I really would like to see a decent resolution to this. so where are we with this option that"s been driving me around the bend. I have read most of the threads about this and the pro's and cons on it all but surely there must be a solution. A flat 11 blade fan set up must be way more efficient with equal air flow over all 4 cylinders than the vertical one. Why is it soo difficult to make an angle drive system as the 935 or a better solution than the problematic fan dual pulley scenario? Also I would have thought there must be an electric light weight fan thats just as efficient now? I am asking because my new engine is going need one. Regards Brent
