Interesting...When my 5-blade was destroyed by a General Lee-style crossing of some train tracks, I switched to a factory 7-blade and it pulls with noticeably more suction, at least just spinning at idle.
Well it seems the smaller pulley made about 5 degrees diff. , not sure, it was only in the mid 80`s but was humid as hell . Stiill wondering how much it will help in the mid to hi 90`s .
