In this picture the right pully on the pther side has a blower brace going from the crank to the blower, Honestly really don't no why it happend, I no you have a scat crank in your motor, The crank that is in my buddies mustang, The orange and purple one that was at track day, He has had that same scat crank in 3 diffrent motor cet-up and never had a problem at all, Scat is one of the best cranks thier are as you no, Guess it is just one of those things that happend. If you want ill take a pic of the crank pully from the other side to showe the blower brace. The blower brace is mad by Bob Kurgan who runs NMRA
