Tight spring does rob power, anything that puts that much side pressure on the belt is going to take power to open,This is an imporant rule when clutching, If the plan is to drag race, I don't know why you would be worried in the powder.The only reason to run that heavy of spring pressure is if your belt is slipping or your going hill climbing in powder snow, other wise a weaker tension will work. This is a 90HP 440, Green spring wound tight is to much, work with the stock spring.
