It seems like an awful lot of work to me to put a CVH engine on the Dyno just to prove a BHP figure. OK, so perhaps you can map it a little easier on the Dyno, but I am not sure that it can necessarily be done any better.

The reason that a CVH (or indeed a 'Normal' Zetec) is never seen on the Dyno is because for the money involved in doing it, most of us have better things to spend the money on. It's different with a Cossie Engine or a Big Zetec because the relative cost of building the engine makes the dyno session a bit less of a shock.

Thats my opinion.
