I have a 2014 California Special 420 hp GT mustang. I want to upgrade to maybe 650hp. what do you suggest I get to get to this range of HP?
Supercharger and upgrade the brakes exhaust and suspension while your at it.
Right of the bat your gonna want to do your basic breathing mods on your car (CAI, etc.). After that you can start doi g some of the higher hp rated bolt ons like headers and pulley. Now for the big stuff. For a mustang I would recommend a supercharger even though im a turbo fan lol. Make sure to ecu tune, boost controller, and I would also recommend some bigger brake pads and some sway/ anti roll bars just so you dont have as much torque steer and it handles a little better. Just some opinions from a 14
