underdrive pulley
I understand how basic engineering works. Take the engine at idle say 800 rpm. No mater the pulley size it is still 800 rpm and the belt travels at basically the same speed to the next pulley. Do you know how much change in pulley size you would need to make any noticeable difference?
Example: New wind energy windmills which turn really slow. The outer most tip of the blade is traveling at something like 300mph. A 1/4" or 1/2" drop in pulley size when the starting point is so small is almost null and void.

realize just cuz some people take the easy route and change the pulley on a s/c to gain more boost, other cars are hindered by electromagnetic s/c pulleys and have to change the CRANK PULLEY to up the boost
just ask the mercedes guys
its all about ratios

I understand how the ENGINE is spinning at 800Rpm's but.. The belt that off the stock pulley a full 3/4 and inch larger in Diameter, would sping the belt at like 200Rpms a minute at idle, now only spinning at like 150. All I am saying man, is that it does change. No matter how minimal, I also did notice a huge diffrence in my lights dimming and on cold morings my car turning over slower, which i do take account for it being my Battery, which would in effect no be charged due to my Altenator. Yet, im not argueing, just simply trying to understand how you see it? You kinda have me a tad lost on your views.
