I think at the eco-modding forum there are some BSFC maps which have been posted in the sticky.Hucho gets into this very well,shows the shifts,and how the gearing should be optimized to get the full-monty.Without the graphics we shouldn't even touch this,and we probably should take it over to the general eco-modding page.I don't have my text.From G.W.Carr,"The Development of a Low-Drag Body Shape for a Small Saloon Car",MIRA Report #2,1965, he shows that you can lose up to 45% of the streamlining benefit without gear-matching.------------ That's all I have with me.------------ The engine see's a lower load with streamlining,and will over-rev without the taller gearing,shortening it's life if not self-destructing.
