I would really enjoy a tad more pep in my 3.0 Ranger. I heard that the pulleys are a nice upgrade.
question: I am running a 12" sub/amp. With the stereo up, my lights already dim pretty bad at night. Would running underdrive pulleys make everything worse? would it be bad for my engine? and would the overdrive alternator pulley solve the problem?
second: i am only planning on buying the crank pulley and alternator pulley (excluding water pump pulley) is the size underdog.com has for rigs with all 3 pulleys? or only the crank pulley? or is the crank pulley the only thing that affects the size of the belt needed?
final question: Will I have to remove anything besides the Belt to remove the crank pulley? (will i have to remove the fan/shroud, etc. to get to the pulley? or are the DIYs on this site saying to do that only when installing the waterpump pulley)
