Ford Shelby SVT Cobra GT500 Mustang 2005

Shelby and Ford have again with a Shelby-branded Mustang, the Shelby GT500, for the 2007 version year. Introduced on the 2005 New York International Auto Show, the GT500 uses a 5.four L Modular supercharged V8, which stocks additives with the Ford GT supercar in addition to the 2000 Cobra R.

The maximum effective factory-produced Mustang ever is the brand new Shelby GT500. Car & Driver placed the Shelby GT500 up towards the Corvette (Z51 package) and will best get 12.nine sec quarter-mile at the same time as the Corvette ran a 12.8. Road & Track mag may want to muster best a 13.1 quarter-mile out of the Shelby GT500. However, Muscle Mustangs and Fast Fords (August 2006 issue) recorded low-12 2nd performances (best: 12.257s), with lure speeds of over 117 mph (temperature sixty six stages F; humidity 46%; strain 29.nine).

Transmission/Gearing/Clutch:

First tools is 2.97:1 (vs. 2.sixty six at the 2003 and 2004s). Rear-give up ratio is 3.31 (vs 3.fifty five at the 2003). Overall tools ratio in 1st is nine.831 (vs nine.443 at the 2003). Also sixth is the equal ratio as 2003 (0.63:1). Clutch is a double-disk unit (215 mm = 8.forty four in) sourced from Valeo. (Smaller diameter reduces polar second of mass inertia so much less inertial loss at some stage in acceleration.)

Engine:

Wet-sumped 5.four L 500 hp iron block with aluminum heads. Bore x Stroke is 3.552 x four.a hundred sixty five inches, generating 330 in³ (5,409 cc) displacement. Static compression ratio is 8.four:1 (equal as Ford GT, however vs. 8.5:1 at the 2003 Cobras.) Forged metal crankshaft is from the Ford GT. Manleys connecting rods which the engineers declare are on par with the Manleys withinside the 2003s, however much less expensive. Heads are at once from the GT, which include cams, valves, springs and ports and actually have the equal element number. The top strength score is at 6000 rpm, and redline is at 6250 rpm.

Supercharger:

Eaton M122H (H for hybrid...revised 5th-gen blower) Roots-fashion blower with nine psi of increase can be used. It has redesigned rotor and port layout Eaton presently claims 15% development in adiabatic performance over the M112. SVT became thinking about the usage of a Lysolm twin-screw unit, however determined towards it for deliver reasons.
