Ford SHO V6 engine

From Wikipedia, the free encyclopedia

Ford Motor Company worked with Yamaha Motor Corporation to develop a compact 60° DOHC V6 engine for transverse application. This V6 was to power a mid-engine sports car in the early 1990s, but that project (known internally as GN34) was cancelled. The company decided to place the engine, dubbed Super High Output (or SHO) into the front wheel drive Ford Taurus sedan.

The SHO engines share a common bell housing pattern with the following Ford engines: the 2.3/2.5 L FWD HSC I4, the 3.0L FWD/RWD Vulcan V6, and the 3.8 FWD Canadian Essex V6.

Due to the engine's aesthetically pleasing appearance and its compatibility with common Ford RWD transmissions, such as the AOD and T-5, it is often transplanted into other vehicles.

[edit] 3.0 L

The SHO V6 was a high-tech design at its debut in 1989. Displacing 3.0L (2986 cc/182 in³), it was an iron block, aluminum head 24-valve DOHC engine with an innovative variable length intake manifold. Its oversquare design, which sported an 89 mm bore and 80 mm stroke, gave the high-revving engine an output of 220 bhp (164 kW) @ 6200 rpm and 200 ft·lbf of torque (271 Nm) @ 4800 rpm at the flywheel. Redline was 7000 rpm, and fuel cut-off occurred at 7300 rpm. This engine was available with a 5 speed manual transmission only.

[edit] 3.2 L

From 1993 to 1995, Ford mated a larger 3.2L (3191 cc/195 in³) version of the 3.0L V6 to an automatic transmission. This new engine, while retaining the same 80 mm stroke of its 3.0L brother, sported a larger 92 mm bore that helped raise torque output to 215 ft·lb (291 Nm) @ 4800 rpm at the flywheel. Horsepower output was still 220 bhp (164 kW,) but now at 6000 rpm: this is due to a slight reduction in intake camshaft duration.

In 1996, Ford replaced this engine with a 3.4L V8 and automatic transmission.
