Regardless of the gear or gearing they will still be the same when rpm hits 5252.

The below information (and dyno run charts) show how dyno numbers can vary by 10% or more depending on the correction factor used, SAE, STD, DIN, etc., smoothing that was used, and the gear in which the dyno run was made.
