The 2007 Shelby GT500 came out with a whopping total of 500 HP, before the power output jumped up to 540 HP in the 2010 model year . Both sets of numbers are rather significant, but with the 2013 Shelby GT500 pushing 650 HP upon its arrival, customers who own a 2007-2012 GT500 may feel as though they are at a disadvantage. Well, worry no more.
Shelby Performance Parts has announced a new supercharger kit for the 5.4-liter V8 engine that can add an impressive 300 HP to the GT500. This means, the total output can be increased to an amazing 840 HP!
The new kit will replace the stock roots-type supercharger and will add a new Competition Heat Exchanger and Shelby GT500 Competition Intercooler Tank to improve cooling performance. The new Competition Heat Exchanger will keep the intake charge cool, while the Competition Intercooler Tank can be filled with ice or dry ice to further reduce intake temperatures.
The bad part to all of this is that there are no pricing details associated with the package as of yet. We’re thinking an upgrade package of this caliber will run customers somewhere in the $5-6K area.
