I wanted to see what everyones thoughts were on lower pulleys? I have seen some recent threads the past 2 years about the crank bolt backing out and causing carnage. Current mods are trinity 2.4 pulley, 67mm TB, 123mm CAI, Hpipe, 93 boostane tune, car made 18psi and 707hp to the tires, 90mm aux idler, Xcal 4 VMP tune.
Would I need to run a bigger pulley to limit belt slip? Can you run an upper and lower combined these days? Do you recommend one or the other?
