- StangNet.com4.0-liter SOHC V-6 – Anything but Basic Performance
With technologies like electronic throttle control, traction control and an available five-speed automatic transmission, the base Mustang’s new 4.0-liter SOHC V-6 powertrain is anything but basic. And with 200 horsepower and 235 foot-pounds of torque, the V-6 engine offers real Mustang performance at a more economical price.
The 4.0-liter V-6 offers improved NVH, higher power output and a more compact package than the previous Mustang’s 3.8-liter pushrod V-6. It features low-profile heads with single overhead cams driven by a slave shaft mounted in the "V" of the engine. This results in a lower overall engine height than a conventional overhead cam setup.
As in V-8 applications, a new composite intake manifold was developed specifically for duty in the Mustang. The 4.0-liter V-6 also gets a unique camshaft grind, new tuned-length exhaust manifolds, a new flywheel and an oil pan. In addition, Mustang engineers designed an enhanced fuel injection system with reduced evaporative leakage, a new EGR system and revised cooling circuit for the 4.0-liter V-6.
Key noise-reducing features of the 4.0-liter SOHC V-6 include a girdled crankcase for increased strength and rigidity, a dual-mode crankshaft damper, coated skirt pistons, optimized bearing clearances and isolated composite cam covers.
Research with current and potential customers played a role in achieving the sound quality buyers expect from a Mustang engine. Listening studies were conducted with current and potential Mustang owners to determine precisely what engine sounds were "powerful." The resulting sound reinforces the American muscle-car personality of the 2005 Mustang.
thats not really the same anymore. Maybe the shortblock is old but everything above that is different.Rick0636 said:Also the OHV and the sohc engine is the same engine, they just changed it around and made it into a sohc.
Congrats. You figured out the the main differnce between all engine. The only real difference is big block or smalll block.Its no different than Ford does with its V8s, they took the 221cu. in V8, bored it stoked it, whatever, and made the 260, 289, 302, 351W, yes the windsor does have some different heads and maybe deck height of the block, but still cut from that same old basic 221 block and modified. Chevy has done more or less the same thing, 265, 283, 327, 302, 350, small block 400, all from the same old block, and you can bet they are probably still pouring blocks in that same old mold at GM now.
