Does gear swap affect dyno #'s?

[Richie7]

Going from stock 3.07 to 3.55 would I expect to see my baseline dyno numbers change from the gear swap itself?? I have searched on this topic and can't seem to find a definitive answer.

i believe it only effects the SOP and not the HP

Minus 2 - 3% off your dyno numbers.

that's what I've always heard, roughly -2% loss in numbers.

Will it also get a better ET and trap higher speed at 1/4mi?

With traction, yes the gears will help ET and MPH. The reason is that you will be accelerating more in 4th gear as you cross the finish line due to the gearing putting you in a higher rpm vs wheel speed.
