There are some serious issues with that torque curve tho..... That is not normal at all! I have dynoed 3 F's and that is not normal... In any mode...
I was wrong, we put the prototype headers in by pulling the subframe. It worked very actually.according to andy, the elite headers require that the engine be removed. it has been stated from sikky that the engine does not have to be removed to install them, it can be done from underneath.
this is a huge factor. especially since i take joy in doing things myself, i will be putting on my headers. this means i have to do a lot less work.
The problem with that is my torque curve never drops in the middle....... his drops 20-30 ftlbs in that valley... That should not happen....At what rpm does the F get "on cam"? Just like a turbo car, the more agressive the cam profile, the more important your exhaust path is. IE, you are going to be seeing larger increases when the car is on the more agressive cam profile.
Also, the torque curves are similar, it's just the different scaling on the graphs that is exagerating the differences. You can see two small peaks in the torque curve on your DD dynno, but the two peaks on the other graph are much more visable due due the differences in scaling.
This says it all, I don't think we need to say much more. But I will add that this really comes down to the difference in dyno's. The dynapack is far more sensitive and will show fluctuations more than the dynojet. The mass of the rollers spinning tends to smooth dyno plots out and will not show the fluctuations that are present as clearly. Also, for comparison sake this setup has no tunning software or AEM ems setup on it. This factor pretty much eliminates the validity of a comparison between the two cars and there dyno plots.
