Turbo or Atmo

Ive driven a couple of Laguna V6s and a few Safrane V6s, felt no different really.

..but you can't honestly compare two of the cars when they are auto's, as you never get the true feedback from the car...and they can just have a duff sensor..

. I'm note sure how it's measured but the cams in the Saf are 1mm larger from tip to base of lobe, than the Z7U, which means 2mm more lift on the valve.

Yes, thats about right. Depends how you work it out. The rocker ratio is 1.33, so 1mm should only increase 1.33mm at the valve, but with the Saf/Laguna being hydraulic, you roughly gain back the 0.7mm clearance you would have on mechanical tappets..in theory.....

Both the Safrane and Laguna V6 run the exact same cams.
