let us suppose we have 2 identical euro spec b16a2 civics with 4.266 final drives.they accelerate side by side because they are the same...now let us soppose the one of the two changes the final drive with a 4.4 one....will the one with the 4.4 be in front of the other or the fact that the one with the 4.266 will stay longer on the lower gears which accelarate better will be able to catch up with the one with the 4.4?
Mods: engine swap, headerback exhaust system, intake all bolted to a slighty built N/A motor
lets say you run the 1/4 mile and both you guys are running the same amount of power and get out of the hole the same and same 60ft times the guy who has the 4.2 will finish in 5th gear and the guy with the 4.4 will cross in 4th the 4.2 would have gotten thier quicker in theroy so there you go hope that helps since most of the honda people only drag not road race.

you have that backwards. the guy with the higer fd will finish in a higher gear because it will accelerate quicker

Question about the original post aren't the final drives on the B16A2 already 4.4?

The final drive ratio is actually the gearing on the differential, the last time input speed from the engine is altered before going to the wheels, higher numbers equal shorter gearing, and lower numbers equal taller gearing. The shorter the gearing the less time you will spend accelerating in the particular gear and your overall top end will be somewhat diminished. You need to decide for yourself or do the math wheather or not you will get through the quarter faster, if this makes you shift to another gear, say into 5th as opposed to finishing in 4th it may not be beneficial, unless you can shift like the flash!

Shorter Final Drives lick on long trips...........trust me on that.....and it depends on what your using your car for, the track? strip? or no reason

lets suppose that the forth is the last gear used.
which one will finish first?

street racing mostly...and every day use...
my fifth right know is 0.878 and with the 4.266 final drive gives 146-148 miles i think.
if I change the final drive I will use a usdm/jdm fifth with 0.84 ratio so I will be ok on long trips.
