Im thinking about some pullies in the near future. My question is, what size belt can i use if i use both the crank, waterpump, and alt pully. I DONT have ac, and i havnt found a belt that i can use.

My other question is this, the alt pully is ment to speed it up to keep the watt output the same. My truck idles at abotu 1100 so i dont think that would be a problem. So could i do with out it, thus getting even more hp?

truck is a 98 4x4 auto 3.0

 

at 1100 rpms you are past the point where idle amperage can be a nuisance. no reason for the alt pulley.

The length should be 85" with the crank pulley and no air conditioning. Water pump is same as stock so it doesn't effect belt length. In gatorback lingo that is 4060850.
