Does the Variable Valve Timing only exist in the V8? It seems that the Variable Valve Timing only exist on the current V8. Did the last gen 16 valve version have it?

Does it make the engine easier to rev?

 

i have no idea what it does but anything older than the 05 mustang gt's does not have it

 

it allows more aggressive cam timing at higher output levels without busting emissions laws. I think they are a waste myself.

 

Correct but can create more power but nothing significant. On a stock car it's great for emmisions and fuel economy.

But since I like to race here is the downside of VCT.......

If the cam keeps the valves open for longer periods of time, as with a racing cam, problems start to occur at the lower engine speeds. This will cause unburnt fuel to exit the engine since the valves are still open. This leads to lower engine performance and increased emissions. Basically it's crap if you plan to do anything internally to the engine. Personally I couldn't have a car that adjusted the timing for me. I would want it tuned and to stay the same way.

 

i think you are beter off with the other one

 

Variable Camshaft Timing (VCT) is an automobile variable valve timing technology developed by Ford. It utilizes electronically controlled hydraulic valves that direct engine oil into the camshaft phaser cavity. These oil control solenoids are bolted into the cylinder heads towards the front of the engine near the camshaft phasers. The powertrain control module (PCM) transmits a signal to the solenoids to move a valve spool that regulates the flow of oil to the phaser cavity. The phaser cavity changes the valve timing by either advancing or retarding the camshafts to allow for optimum engine performance, reduced emissions, and increased fuel efficiency. VCT effectively replaces the external Exhaust Gas Recirculation (EGR) system.

Variable camshaft timing was a key in the quest to wring more power from the Mustang’s 4.6-liter, three-valve MOD V-8 engine, while simultaneously improving efficiency and reducing emissions. VCT lets allows the valves operate at optimum points in the combustion cycle, tailored to the engine’s speed and load at that instant. Simular to the Honda VTEC

The VCT system is used in Ford's Triton 5.4L 3-valve V8 engine; the Australian Barra 182 and 240 Inline-6s; Ford's 4.6L 3-valve V8 engine used in the 2006-present Ford Explorer and 2005-present Ford Mustang GT; and the 2.0L Zetec Inline-4 used in the 1998-2003 Ford Escort ZX2, 2000 Ford Focus and 1995-2000 Ford Contour/Mercury Mystique.

 

Ok so I have a 2007 mustang gt with original motor n bought a new 2012 4.6l 3v sohc motor was told it would swap out just have to change some components however came to find out the 2012 motor doesn't have (VCT) AND my mustangdoes is there anyway to swap motors n eliminate the sensor so codes dnt confuse computer or what's best option here
