More on the vct system

Here are a few additional graphs showing the operation of the vct system in just an on/off mode.

• Run 3 is with VVT on all the way
• Run 4 is with VVT off all the way
• Run 8 is with VVT on up to 5500 and off after, plus final tweaks on fuel and
  ignition.

What really stands out is the additional mid range that it fills, and clearly the cam is capable of making power high up the rev range (normally compramised with the mid and low down).

Will try and writ some more on this interesting subject when I get chance.
