I'm thinking about putting a pulley on my cobra.My question is whats the best size im hearing different things,not to go to small or you over spin the supercharger and actually loose top end power,due to slipping and heat.I have a steeda cold air,borla stinger cat back,predator,pro 5.0 shifter,and 17 by 10.5 rims in rear with 315 nitto drag radials.I'm thinking of 2.93 or 2.80 with a UPR belt tensioner and leaving lower pulley stock for now.Any and all advise would be appreciated.
