2013 GT500 to be Turbocharged

Turbo's more efficient, ecoboost would be even MORE efficient.

Response is quicker too.

not that much more effiient, as the rotor transfers exaust heat to intake air

turbos have to spool up, a Keene Bell Supercharger does not. KB has boost at 1500 RPM

Turbos require hot tubing in engine, pop off etc.

And a twin turbo Mustang can make twice as much power as a blown one with less effort. Simple research will turn up that info

No, it's not the heat, it's the pressure from the exhaust that spins it, and it takes relatively very little power to spin.

The supercharger can take about 50hp to spin at high rpm.

Smaller turbos spin up pretty quick, not much lag at all. They also keep spinning, far more top-end boost than that twin-screw

This is the GT500 we're talking about here, if they use a 351 it's going to be a monster

Just read an update that it's the 5.0, not a 5.8 going in the GT500.

To be clear it seems it's still either going to be an enlarged 5.8 or the newer 5.O motor.
