2018-20 Mustang GT Whipple Stage 1 Supercharger Kit / Intercooled / BlackMike FillingerNovember 2, 2018This thing is crazy! Good crazy! I had this installed at Brenspeed and it made over 650 rwhp on the dyno! I finally beat my neighbors vette. It looks cool and my stang is a sleeper. I cant believe how much power this thing produces. I had a fox body that made 600 rwhp and it drove like poop. This baby drives like a dream. I am going to have to get the stage 2 upgrade next year for sure once I get used to this! Thanks Brenspeed!
