Power all over the rev band. Slight divergance.. Really interesting to see this graph and comparing it to the graph pinned to my noticeboard.. My Crate 2.0 black top with at the time 500 miles, Omex throttle bodies and Home made 4-2-1 exhaust. It is almost identical in power within a few horses up to 5.5K.. One would assume on similar gearing they would be similar to drive. My losses are quoted a little higher (ambient temp was 3 degrees so the gear oil was probably like cold lard. After 5.5K the black top graph begins to level off and produces 185 at 7k (my limiter), where the K series makes 192 ish @7K... It's not the same dyno but it is a MaHa. Looks like this K series aces my standard 2.0 blacktop. Link to comment Share on other sites More sharing options...

There's still time if not I intend to, but I still have to prove to myself that the car is OK, the present weather hasn't helped. Link to comment Share on other sites More sharing options...

Looks like this K series aces my standard 2.0 blacktop. Its not a standard K by a long way though.... Interesting comparison though, having 200cc more will be the most obvious benefit for the Zetec, that and the fact a standard Zetec head flows as well as a ported K series one! 1.8k vs 1.8 Zetec will make the same kind of power with the same kind of work. K just has the benefit of being around 30kg lighter than the Zetec. Link to comment Share on other sites More sharing options...
DamperMan Posted March 16, 2018 Share Posted March 16, 2018 A brand new.. virgin 2.o zetec costs £1000... zetec bomb proof in standard form.. 30kg is a lot of weight agvantage for a K series.. got to drill a lot of holes instuff to win 30kg. Would need at least 5% more power just to break even. Link to comment Share on other sites More sharing options...
