Rumor: 2013 Shelby GT500 To Have At Least 600HP

Posted by on March 15, 2011 - more

According to sources at CarAndDriver, the 2013 Shelby GT500 will be more than ready to respond to the Camaro ZL1, as the GT500’s power will be pushed to at least 600 horsepower.

Our well-informed sources say the stratospheric output figure, which could be as high as 620 horses, is the result of boring out the current 5.4-liter V-8 to 5.8 liters and swapping the existing Eaton M112 supercharger for the same firm’s more-efficient and quieter TVS unit. This supercharger, with its four-lobe rotors, is the blower of choice for the Audi S4, Cadillac CTS-V, Chevrolet Corvette ZR1 and, interestingly, the Camaro ZL1.

If this turns out to be true, we can knock out the possibility of that EcoBoost Shelby GT500 for the 2013 model year.

They also hint at design changes coming up for the 2013 model year but offer very little input as to what will change other than it will be “less retro” and “more modern and edgy”.

    The engine bore doesn’t make sense to me. Just swap the blower and run a smaller pulley. I would rather see a 5.4 tivct blown engine. Or just swap in the new 6.2l tivct modular. N/a that would be more than 500hp. A small blower would get you 600 easily.

  2. They probably chose to bore it to 5.8L because that was a previously used displacement in Mustang engines, much like the new 5.0L is a numerical tribute to the 302. 5.8Ls or 351s, were used in Mach 1 Mustangs 1969-1973.
