Need some help on pulley sizing
When you buy those fancy alum pulley kits that advertise 'more hp' because they have reduced the size of driven pulleys, they do not tell you that the overheating you are going to get is included in the price!!
Use a 160-180 t/stat, not a restrictor. Use a shroud & plug any gaps so that ALL the air is pulled through the rad core, not though gaps.
