Can a few of you veterans out there please offer feedback regarding this dynograph?
This is new to me, but I am skeptical here. (IMG:style_emoticons/default/confused24.gif) Thanks! Mike in Munich Attached thumbnail(s) |

Hi Jeff,
Thanks for your input. I would have been specific but the engine was already done before I bought the car. I do realize that it would be recommendable to change the cam as well as the valves, etc. along with the heads. I may well just accept it as is and if I am not satisfied with its performance I may, as you suggest, eventually have an entire engine sent over here next time I re-import one. (IMG:style_emoticons/default/idea.gif) Extra space in the container goes for about $175 a cu. meter. I'm interested in opinions about HAVING to shift at 4500 or lower. Is this normal? Would it be extremely annoying? Not optimal but acceptable? Opinions? (IMG:style_emoticons/default/popcorn[1].gif) M.i.M. |

Without a build sheet for that engine its impossible to prescribe any remedy short of a complete rebuild. |

Am I the only one noticing he is running the OBX header? I have no personal experience with them, but from what I have read they could be the problem.

I'm sure *if* one manages to make them fit, they probably work fine. However, last i heard, they need cutting and rewelding to fit and seal correctly. (IMG:style_emoticons/default/idea.gif) |

(IMG:style_emoticons/default/idea.gif) Hello Sir Andy, we die have to modify them and did MAKE them fit. I was not personally involved in this "we", but it is my project, so...
