So what do you gain with Double Throttle Bodies and Two Plenums?
I can understand that if I bumped the Stock Displacement of a 2.0, I'd get higher vacuum at the same RPM (making no changes to valve and cams). I'm assuming that this higher vacuum gets out of the range of the MAP sensor so the computer doensnt' get signal to send MORE gas? If I split the airflow into two seperate throttle bodies, I can see how Pressure-Drop or Vacuum would be reduced quite a bit for the same airflow since I'm flowing only to 2 cylinders. Is this the idea? |
