<div>Honda and Acura made their VTEC equipped engines famous with the import tuner crowd in the mid-90's. Now Ford is launching the DOHC technological advancement with its Twin Independent Variable Camshaft Timing (Ti-VCT) system for the 2011 Mustang. VCT is a huge leap for Ford since the modular engine first appeared in a Mustang in 1996. Camshafts have only been able to open the valves at a fixed point defined during engine design and manufacturing.<br />
<br />
The 300 horsepower 3.7-liter V6 was introduced yesterday at the LA Autoshow with Ti-VCT and we expect the 400 horsepower 5.0-liter V8 to be announced soon with the same system. <br />
<br />
With Fords new 2011 Mustang engine line, modern variable cam timing systems were part of the design plan from the start allowing the camshafts to be rotated slightly relative to their initial position, allowing the cam timing to be “advanced” or “retarded.”<br />

<br />
The Mustang's Ti-VCT system uses electronic solenoid valves to direct high-pressure oil to control vanes in each of the camshaft sprocket housings. Each camshaft has one solenoid valve and is controlled by the Electronic Control Module (ECM). The intake and exhaust cams can be advanced or retarded independently of the other as engine operating conditions change, providing an exceptional degree of valve timing control.<br />

<br />
According to Ford, the Ti-VCT system delivers better off-the-line launch feel and a 5 percent improvement in low-end torque. The system also delivers at the top end with a 7 percent improvement in peak power versus non-Ti-VCT-equipped engines. The system also improves fuel economy with the 2011 Mustang rated at 19 mpg city/30 highway with six-speed automatic transmission and 18 mpg city/29 highway with six-speed manual transmission. <br />
<br />
“This overlap control via Ti-VCT helps us eliminate compromises in the induction and exhaust systems,” said Jim Mazuchowski, Ford manager of V-6 powertrain operations. “Drivers are going to notice improved low-speed torque and increased fuel economy and peak horsepower. Plus, there are benefits they won’t notice, too, such as reduced emissions overall, especially at part-throttle.”<br />
