A dyno run is in the gear closest to (on or below) 1:1 ratio to the cars FD

for example , most manual cars do a dyno power run in 4th gear.

So, you would find your gear which is closest and run low rpm to redline in that to give the most accurate power at the wheels readout. Make sense?




PS if you ran in 1st or 2nd gear the readout would be higher than actual, relevant to the mechanical ratio.
