Broke down and bought an underdrive pulley
I finally broke down and bought an underdrive pulley for my 03 sohc. How long has it taken to install for those who have done the mod? I was also thinking about going ahead and converting to an efan, but im not sure if its gonna be reliable enough. And what lind of performance/mileage gains have yall seen? Jusnes Modified (where i bought it from) said 12-15 hp and 2-3 mpg, but i was looking for real world numbers.
