is the new ford 4.6 liter supposed to have some time of variable valve ? I was just comparing ford technology to toyota or honda..

kinda behind I guess

what other differences is their and why is it like this?

 

yeah i think it does

 

Yes it is a three valve(two intake 1 exhaust) with variable timing. In fact Ford has taken this technology to alot of its motors, the 5.4 and v-10 for two examples. My truck has it and it is like night and day at the way it runs compared to a older 5.4

 

I know the old 4.6 certainly has enough room in the valvetrain to support a wide variety of VVT ideas.

All I can say is its about damn time.

 

eh, my vtec jumps in from idle with my pushrods.

 

is the one exaust valve on the new motors like extra big or somthing? i dont understand why they would do a 3 valve instead of just fully upgrading to the 4 valve?

 

i got vtec to...

 

another cam shaft probably I don't think they could fit that many lobes on a sohc to do 4 cams a cylinder

but that is just my assumtion

 

They've had VCT (Variable Cam Timing) since 1995 or so in the states... Just in the 4 cylinder Zetecs. Nothing new, just implementing it into the V-8's, where many of the other manufacturers have not gone.

 

3 valves per cylinder? Cool, that's what my MX-6 has.
Something else it has that a Honda doesn't- torque.
