Far too many people generalise.....point being I have seen some seriously pathetic excuses of ZVH engines as I have Zetec and CVH. There have been some CVH engines that have been properly engineered and produced results that would blow the doors of most ZVH or Zetec Turbo's however CVH boys wait until you've seen a proper
dyno not RR graph from a properly engineered ZVH engine. I am on the case and should have something posted soon.
