OMG you did frankenplenum correct?

I saw that and did have hopes for a performance gain....

I hear what you are saying, and it does make sense, however, I am pretty sure that the dropped plenum does actually make an improvement in track times and HP numbers.. please advise if this is not true..... or true...

Does anyone have a before and after story of a dropped plenum?

It?s often misleading when you see dyno tests due to variances in heat soak or weather. I tested 3 air intakes on an SLK55 AMG and it looked like one produced 12 more hp than the others but in reality it was just the manifold and engine temps that made the difference. So many tests you see could just be variances in condition
