I get it... just disappointing given all that... no one has ever published actual data instead we have feelings.
FPP did the design work on this pipe around 20 years ago. Back then they did publish dyno curves.
But all that was popular back then was racing, So that was the target audiance. Top speed was king.
Since then, those of us who know Ross, basicly keep begging him to keep producing these pipes.
I would highly doubt they would put in the effort to do bottom end testing?
All that being said, I prefer the Limited chamber for bottom end performance on my motor packages.
The higher volume chamber is the key to low rpm power delivery. The correct water injection parameters
Make this chamber work that much better.
