SO Hurricane at drag strip

3.55s FTW!

3.21 will be faster for a roll or top end pull from highway speeds, 3.92 will be better from a launch. There is no free lunch in rear gearing you either give up low end or top end. Can’t have both.

I was just thinking, is it possible lower axle ratios could, at times depending on track conditions, allow wheel spinning on launch thus costing time? Maybe the 3:21s wouldn't be so quick to "break loose". I don't know what the answer is, track conditions, tire abilities, driver all play into the equation.

Taller gears usually prevail in the 1/4 of you know what you’re doing. It’s about the drivers ability, and the setup. 3.21s are definitely not drag gears.

Best gear ratio depends on the entire combo. From engine powerband, launch RPM, transmission gear ratios, finishine RPM, tire size.... Especially in the 1/4 mile where a taller gear can out you into a situation where you need to shift into higher transmission gear shortly before finish line
