If you are a newcomer to my Blog, the story behind my Shelby, “SoScary”, starts here.
The “Trinity” engine in the 2013/2014 Shelby is an awesome motor. Each engine is hand built by two highly experienced SVT (Special Vehicle Team) specialists whose signatures are on a plate that is attached to the engine. For those of you who want to read a great article on this motor look no further than this article on Mustang360 magazine:
2013 Ford Shelby GT500 Trinity 5.8L V8 – Power Of Three
To give you an idea of the comparison differences between the stock TVS supercharger (above) and the VMP Gen II supercharger I replaced it with, here is a photo. The VMP Gen I blower is also shown. The big difference is in the porting. The VMP Gen II can suck in a lot more air as it is much less restrictive.
To take advantage of the bigger porting on the VMP Gen II supercharger, requires a bigger throttle body. The stock throttle body is a 54mm one – this was upgraded to VMP’s enormous 67mm twin throttle body.
All upgrades require a new tune to be uploaded. VMP provided me with a complete custom Stage 4 tune and I uploaded it using my SCT4 Tuner
