How is one going to determine performance potential?The engine builder can't possibly do this, as the dyno does not represent true conditions.Who will be the judge?What chassis,tire,damper,aero,driver,package will be used to compare?Seems that the testing that has been done is fairly "loosey goosey".Panic from one race surely can't be used as relative data.Who is going to pay for the correct testing?Seems that by the time this is worked out the Zetec will only be available in your local wrecking yard.So what was the objective?I realize that a lot of people did some good work on this project,but I just fail to see the benefit with regard to FC numbers,or anything else for that matter.Are there really 4 different kinds of Zetec formulas out there?[Cooper,Pacific,F2000twice/SCCA club]If that is not confusing to a newbie I don't know what is.
