- 4.0L V6 Specific (http://www.mustangforums.com/forum/forumdisplay.php?f=48)

- - VCT? (http://www.mustangforums.com/forum/showthread.php?t=49237)

Ok so I was tearing apart the internet looking for a supercharger for my v6 when I came upon some interesting stuff (to me it was anyway)

Quote:

The 2005 Mustang GT's new aluminum MOD (modular) V8 is a single overhead cam design using three valves (2 intake, 1 exhaust) per cylinder. Incorporated in this new engine is Ford's VCT or variable camshaft timing, which is their version of a concept that has been used successfully by Japanese automakers for years. It essentially allows for variation of the overall valve timing and can optimize power output over a wider engine RPM range. Although not as sophisticated as some other systems out there, Ford states that their VCT is far less complex and lighter than others.

So basically ford vtec
How come they don't say anything about this in any American car magazines?? (that I've read anyway)
Do GTs that stay in america have this?? It doesn't say on the ford website.... http://www.fordvehicles.com/cars/mus...eatures/specs/
So what does this have to do with 4.0 v6s??
4.0 v6 ford falcons in Australia have it http://www.ford.com.au/falcon/htmlPa...tination=specs
they're DOHC and we have SOHC. I wonder if you got your hands on what ever makes this VCT work in the falcons and could find someone who REALLY knew what they doing...... probably not, I dont even know how it works let alone how you could modify it.
anyone out there know more about this??

oops after reading more i guess falcons are in line 6s (it said 4.0 l6 thought the l was for litre LOL what an idiot!!sorry but i don't see l6.... uumm... well.. ever)
still kinda weird I've never even heard of this vct stuff before

The only supercharger I've found that's even close is at explorerexpress.com. They make one for the 4.0 in the explorer, that they've told me only needs modified *slightly* to work in the mustang. However, they have yet to complete this modification, or verify that it actually can be done.

Sorry, don't really know anything about the VCT, just letting you know my search results (I've been looking too).

Maybe you're not reading the right magazines??? I've seen a number of discussions on the variable camshaft timing for several months now, especially as it relates to modding the 4.6L 3V.

hmmm wonder why ford doesn't mention it on the web site...

after looking around somemore i did see a couple references to it online.
forgive me but the last ford I owned was a 1978 ford fiesta.
its probably so old people just dont talk about it anymore lol

The following is from here: http://www.fast-autos.net/ford/05fordmustang.html

There is a lot of other info on that site, too.

Variable Camshaft Timing – Power Without Penalty

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.

The Mustang VCT system allows up to 50 degrees of cam variation in relation to the crankshaft angle. Ford’s "dual-equal" variable cam timing design shifts timing of both the intake and exhaust valves together, with one camshaft per cylinder head. This provides all the benefits of, but creates far less complexity and adds less weight than, VCT systems that actuate the intake and exhaust valves separately.

The cams operate both sets of valves using low-profile roller-finger followers, helping reduce friction and keep the overall engine height – and thus, hood line – low. Cam position is controlled by an electronic solenoid that modulates oil pressure to advance or retard the cam timing based on input from the engine’s electronic control computer.
