So in other words, Dyno calibration settings vary and can be changed from SAE to Standard by the operator, giving totally different dyno numbers
altitude,humidity,temperature can have a huge effect on dyno results when not using SAE corrected settings
Speed shops can exaggerate these numbers by using certain calibrations to inflate their numbers to make customer happy. From my experience only, all dyno numbers should be SAE corrected and smooth 5 for true numbers. Having said that 489 RWHP for Manny's car aint bad at all. I know that Champion will alway give you SAE and not standard.
Some people are just never happy
No matter , 450 , 470 , 500 dosen't matter to me one bit becuase I am happy with my car .
Say Mr. Vettefan , just who are you anyway , sure seem to have a lot of first hand knowledge
