I haven't taken this thread in a negative way. The frustration is of course the lack of application specific comparative data. As stated we need a controlled dyno test of the various sytems.
This runs into a mirad of problems, most significantly the definition of our application. I have built my engine around what I believe to be the most common upgrades for a mid-level CIS engine. That is my baseline.
Dyno testing these systems would be, pardon the pun, exhausting. You are talking small differences that are hard to see on a dyno yet easy to feel on the street. Driveability enhancement is difficult to see on a full throttle dyno pull. With each new system you would have to tweak the AFRs and be confident that the charge air temp remains the same. Not as easy as it sounds.
I do plan to do this type of testing when time permits. One thing I would like to stress is that I am not fixated on any one design just because I sell it. The designs must sell themselves. If I have made a miscalculation and find a design is substandard it will be changed.
