Re: VCT abilities
the VCT (from my limited understanding) simply changes the timing of the cam at the 3700rpm range (in the AU at least).
Stolen from another thread:
VCT - Variable Cam Timing. IIRC the Falcon Six's VCT setup retards the cam timing by 10 degrees after the engine revs exceed 4000rpm(is actually 3700rpm). From my understanding of it, what happens is that when the engine revs exceed 4000rpm, the engine retards the camshaft timing 10 degrees in relation to the crankshaft position, which allows a better higher RPM cylinder fill. Unfortunately, it also retards the exhaust timing, being the Falcon's head is still an SOHC design. This feature should be better when the Falcon comes out with a DOHC head.
I'm not sure about the actual retardation, I thought it was 13 degrees however the concept is correct.
So can you use a more agressive cam? Thats a good quetion which I would love to find out myself.
