So, based on my eurocharged 65mm pulley, you seem to be saying I could easily add a 178 crank pulley without other/further mods except perhaps a retune? If so, what whp/tq gains from a dynoed 340 would that offer given my sig if anyone wants to hazard an opinion? Thanks in advance. (Yes, I did see the table but was unsure of my interpretation)


@boostmonkey; The 65mm and 178mm pulleys are approximately a 15% increase in supercharger speed. Many have run these all day long with no fuel mods - easy power.
