Deeper gears less effective ?

that's a lot of math to say something pretty simple... lol.

I notice it when I was figuring something else out, thought might be of help/interest for some, Yes in the end of the day it didn't add anything much new, basically confirms that 3.55-3.91 give the most bang for the buck, It might give some explanation why though.

I've not heard anyone ever say that the gain remains equal throughout every change.

Some do some don't, now I know at least this one aspect of gears don't.

Did you know on a 440, that the gain from going from a 3 hp lawn mower air filter to a 14x2" air filter is greater than going from a 14x2" to a 14x3" air filter? Once you go from the lawn mower air filter to the 14", the gains will not be the same even if you stack three 14" air filters on top each other. The % of change dwindles.

Gotta tease ya... :poke:
:lol:

lol :)

Another thing I noticed 5.13 only has a 20 mph gap between 3,000-6,000 rpm (20-40mph) and 2.76 has an almost 40 mph gap (37-74mph) so not only do you have to get up to 37 mph with 2.76 to get into the powerband but almost have to accelerate 2 mph for every one mph (twice the rate) 5.13 would have to, luckily 3.55-3.91+ will also get you to 50-65%+ of that too.
