Have a T-trim with cog pullies on a 331 5.0 in a 85 mustang. I havent run it yet still winter in Chi Town but was wondering if running 20 lbs of boost if I will def need a blower brace. I will get one if I need on, I know there cheap but if I dont have to waste the 75 bucks then I wont. Thanks 4 the help.
