I disagree. They are industry standard and the hardest to manipulate numbers (correct me if I'm wrong). And there are more variables when dynoing on different dyno's different days. Temp, alt, etc.
Those numbers are sick for NA Honda's.
I can see someone sand bagging their quarter mile run if their main intention is street racing and winning big money.
My uncle used to street race up there (Grand Nationals). he said those boys race for pink slips as well. Y'all crazy up there.
